Keywords: Sour Cherry, Pre-Treatments, Diameter Classes, Root-Cuttings.
Abstract: his study was conducted at the Faculty of Forestry, SKUAST-K wherein different pre-treatments were used for dormancy release and effect of rootcutting thickness on Sour cherry (Prunus cerasus L.). Out of the tested pre-treatments, mechanical scarification and cold stratification were significant compared to control with maximum germination (30.25 %) observed in case of cold stratification. Significant effect of root cutting thickness on all the tested parameters except the sprouting percentage was observed. 4th diameter class (D ) showed maximum results for 4 sprouting percentage (65.00), survival percentage (57.64), shoot height (27.40cm) and collar diameter (5.28mm) which was however at par with 3rd diameter class (D ). Thus pre-treatment cold stratification and diameter 3 classes D and D are recommended for dormancy release and propagation 4 3 of Sour cherry respectively.

Subject: Ethephon (2-Chloroethylphosphonic Acid) Application and Gummosis in Anogeissus pendula Edgew.
Keywords: Bundelkhand Region, Gum Inducer, Gum-Gatti, Sugar Content
Abstract: Present study was carried out to standardize the dose of ethephon (2- chloroethylphosphonic acid), a gum inducer hormone and suitable month for its application to optimize gum yield from Anogeissus pendula without deteriorating tree health. Separate A. pendula trees were used to inject with three different doses of ethephon viz., 390 mg/4ml (10%), 780 mg/4 ml (20%) and 1170 mg/4 ml (30%) active ingredients at monthly intervals during a complete year (March, 2010 to February, 2011). Increase in mean gum yield with the increase in ethephon dose was recorded. Maximum mean gum yield was recorded in March, 2010 (57.18 g/tree) and minimum in August, 2010 (0.17 g/tree). The cumulative gum yield was recorded maximum during summer (1028.90 g), followed by winter (965.00 g) and rainy season (862.00 g). Applications of ethephon had no effect on tree health; however, its use significantly increased sugar content of the wood after one month of the application. Higher dose of ethephon produced higher sugar content in the wood of A. pendula. Thus, the results of present study suggested that higher gum yield can be obtained from higher dose of ethephon during summer season, without affecting the tree health.

Subject: Agro Forestry and Sustainable Vegetable Production in Kumaun Lesser Himalaya
Keywords: Agroforestry, Vegetable, Agriculture, Constraints, Socioeconomic.
Abstract: The study focused on distribution of tree species and on vegetable crops which are grown under them. The aim was to identify the problem faced by farmers, farm characteristics and methods to improve the production system in kumaun lesser Himalayas of state Uttarakhand in India. A total 90 households were selected on the basis of economic criteria of land holding and occupation as landless, small, medium, big and large farmers. Questionnaires were prepared for survey. Farmers were primarily smallholders with access to less than one hectare of land. A total of 33 tree species were found. The most common species were Prunus persica (29.72), Prunus armenica (22.63), Citrus limon (21.68), Prunus domestica (18.68), while low prevalence species were Actinidia deliciosa (0.304), Melia azedarach (0.447) and Terminalia belerica (0.51). 19 vegetables species were grown in the area with most common being Pisum sativum, Solanum tuberosum, Phaseolus vulgaris, Brassica oleracea and Lycopersicon esculentum. Farmers earned income from selling fruits and vegetables. Vegetable agro forestry was not being conducted in a planned manner primarily due to lack of proper knowledge and awareness amongst farmers followed by frequent landslides in the area. Study concluded that proper training for farmers, enforcement of village by-laws on animal grazing, and facilitation of farmers' access to credit are the major approaches to enhance the adoption of technology. A participatory approach is more likely to achieve success with indigenous people, than the traditional technology transfer approach.

Subject: Evaluation and Optimization of DNA Extraction Protocol from Leaves of an Endangered Forest Tree Species Strychnos potatorum Linn. F
Keywords: Strychnos potatorum, Genomic DNA Extraction, CTAB Method, PCR Amplification.
Abstract: Although, several protocols are available for isolation of DNA form plants, it is essential to compare and establish a suitable protocol for isolation of intact and high quality genomic DNA in medicinal plants. This is fundamental in plants containing active biomolecules and is also essential and important in downstream studies like PCR, genetic transformation and genetic evolution studies etc. In the present investigation, three different cetyl trimethyl ammonium bromide (CTAB) based protocols have been used, compared and finally an efficient modified CTAB protocol was developed for DNA isolation from fresh leaves of medicinally important forest tree species Strychnos potatorum Linn. F. Key steps modified in the CTAB protocol were avoiding of â-mercapto ethanol and addition of polyvinyl pyrrolidine (PVP) and Ascorbic acids. This protocol yielded genomic DNA with excellent spectral qualities, increased yield (1.06μg/g) and purity (1.836). DNA extracted by this method is subjected for PCR amplification using an arbitrary RAPD primer OPA 10 and resulted in better amplification. Thus, the present modified Saghai-Maroof's CTAB protocol developed for isolation of genomic DNA is an efficient, inexpensive, simple, rapid, high yield, pure and suitable for further molecular studies in S. potatorum a medicinally important forest tree.

Abstract: Himalayan ecoterrains are globally known as hub and store house of Asian endemic taxa, and the diversity within ecosystems varies from tropical to alpine meadows. Investigation on assessment of vegetation compositions, forest types and floristic analysis of Nokrek biosphere reserve (NBR) in Northeast India were carried out in eight successive years between 2007 and 2015. Two hundred line transects were laid down randomly of 50m x 10m and in total 1406 species 6 subspecies 8 varieties of957 genera and 155 families identified from NBR. Out of the total species studied, 991 species are dicotyledons, and 294 species are monocotyledons. In addition, 113 species of lycophytes and ferns and 8 species of gymnosperms are also documented. In terms of species diversity, Orchidaceae is the most dominant family represented by 141 species, followed by Poaceae (91 spp.), Euphorbiaceae (56 spp.) and Rubiaceae (54 spp.). The present communication deals with information on forest types, floristic compositions and economic valued plants of NBR. Jhum cultivation, coal mining and limestone extraction are the main human activities exploiting the natural ecosystem of this biosphere reserve. This research will be helpful in formulating future conservation strategies for endangered taxa of Nokrek and adjoining areas.

Keywords: Vegetative Propagation, Air-Layering, Endangered Plant, Ulmus wallichiana, LCMS.
Abstract: Ulmus wallichiana is an endangered plant used for healing fractures in folk tradition of Uttarakhand Himalayas, India. Four bioactive metabolites for osteogenic activity have been isolated from the bark of this plant. Habitat degradation, biotic interferences and indiscriminate collection shows decline in species richness and total tree density in Indian Himalayas. This paper reports a fast and effective protocol for vegetative propagation of this plant using stem cuttings and air layering technologies along with Liquid Chromatography Mass Spectrometry (LCMS) analysis of developed plants. Different sizes of coppice shoots and hormonal concentrations i.e. Indole 3-acetic acid (IAA), Indole 3-butyric acid (IBA) and 2, 4 dichlorophenoxy acetic acid (2, 4-D) were used for standardization of optimal conditions for vegetative propagation. 3000 ppm IAA under 65-95% RH and 25-41°C temperature resulted in optimal number of 21.2 sprouts per explants and 6 % rooting through stem cuttings. However, 100 % rooting with an optimal number of 20.7 sprouts was achieved through air layering and it proved to be a better and more efficient technology. The developed plants have been successfully established and acclimatized in tropical environment Moreover, LCMS analysis of leaves from acclimatized plants showed higher peak abundance of quercetin-3-O-alpha-L- rhamnopyranoside, an important metabolite for osteogenic activity.

Abstract: Aporosa bourdillonii is a little known rare, endemic tree species from the evergreen forests of Western Ghats. In Kerala, it perseveres only in an isolated location of Thrissur Forests. This study assessed the ecology, status analysis and vegetative propagation potentials of this naturally vulnerable plant. The low reproductive success of A. bourdillonii leads to the extinction of the species in the nearby future. Successful population reinforcement had been made by nursery techniques to conserve this species. The data presented in this paper would provide useful information for the conservation of this rare and endemic taxon.

Keywords: Salinity, Ceriops, Starch, Sugar, Glycinebetaine, Propagules.
Abstract: This study was conducted mainly to assess the effect of NaCl salinity on amino acid, total sugar, starch, Proline and glycinebetaine content of Ceriops decandra. One month old, mature and healthy seedlings were selected for NaCl treatment and seedlings were treated with 200, 400, 600 and 800 mM NaCl by soil drenching method. The samples were collected on 60th, 90th and 120th days after planting (DAP). The results showed that total sugars content were increased in 800 mM NaCl treated leaves of Ceriops decandra. However 400 mM NaCl treated leaves of Ceriops decandra showed no significant increment in sugar content. Starch content showed gradual increment in 400 mM concentration in all the three plant tissues but 600 mM and 800 mM showed decreased starch content when compared to control and other treatments. There was a slight increase in the level of proline content from 200 mM to higher concentration in all the three tissues on all the sampling days with increasing NaCl concentration up to 800 mM. Glycinebetaine content showed considerable increase in the accumulation at increasing salinity up to 800 mM. The amino acids content showed gradual increase up to 800 mM NaCl and highest value also obtained in 800 mM NaCl.

Abstract: A study was undertaken to assess the impact of the existing ban on green felling of trees in Chirpine (Pinus roxburghii) areas above 1,000 m altitude in Uttarakhand state, India. Crop composition, regeneration status and soil nutrients were studied for 374 sample plots in eleven forest divisions representing the entire ban-affected area of the species to analyse differences between felled coupes and control plots (un-felled forest where the prescribed felling could not be done due to ban). On the expected lines, the control areas were found to have significantly higher proportion of very dense forests (54 per cent) than in treated areas (38 per cent). The number of total tree species in treated areas was more (34) than in the control areas (23). Chirpine was the dominant species from standpoint of tree density forming 80.96-100 per cent and 71.03-100 per cent of tree population in treated and control stands respectively. However, in Pithoragarh control areas, chirpine component has decreased from 86.27 per cent in treated areas to 71.03 in control areas. Treated areas had greater diversity of shrubs than the control areas. However, significant differences were not observed in IVI values of tree species in treated and control areas, except for Rhododendron arboreum which recorded significantly greater IVI for control area vis-Ã -vis treated area. Shrub species were found to have significantly higher IVI values in the control areas than in the treated areas thereby implying that weed species like Eupatorium spp., Ageratum conyzoides and Berberis asiatica have steadily gained space in the control areas. Out of the 11 forest divisions where this study was conducted, regeneration in treated areas was good in one and fair in nine forest divisions while in control areas it was poor in eight forest divisions. Regeneration was absent in one forest division. Though seedlings of regeneration were recorded in control areas of seven forest divisions, saplings were absent. Soil fertility in treated areas was generally better than the control, thereby dispelling the fears that opening of canopy might lead to reduction in soil fertility.

Keywords: Santalum album, Heartwood Formation, Oil Per Cent, Edaphoclimatic Factors.
Abstract: Santalum album is regarded as the only species in Genus Santalum yielding high quality sandal oil. In India, However, a scientific assessment on heartwood and oil yield in non-traditional areas is lacking. Core samples from around 168 sandalwood (Santalum album) trees aged between 8 to 35 years and above and girth class ranging between 30 to ≥ 80 cm were extracted at breast height (1.76m) using Hagl-of increment borer from 22 locations across seven states during 2015-2016 to assess variation in heart wood and oil yield. Data revealed that the overall oil content in heartwood in all the girth classes ranged between 1.0 to 4.0%. Mean percent of heartwood and oil increased significantly with age. Maximum oil concentration (4.38%) was observed in natural population in Marayoor (Kerala) in girth class 70-80cm whereas in similar girth class in Madhya Pradesh the maximum oil obtained (1.52%) was substantially low. In sandalwood samples from other states like Maharashtra, Orissa, Punjab and Rajasthan, the maximum oil concentration was in 1.0- 2.29% range and was observed in the girth class ≥ 80cm. Oil per cent estimated was correlated with heartwood content and was found to vary significantly with girth class and locations. The present study indicates that though Santalum album may grow well across states in India there is no uniform pattern in heartwood formation and oil content with the increasing age of the tree which may be attributed to varying edapho-climatic conditions and source material.

In agrisilviculture system, canopy management like pruning is an essential silvicultural management practice for reducing both above and below ground competition with associated crop. The experiment consists of four pruning intensities viz: no pruning, 25% pruning, 50% pruning and 75% pruning and one open condition (no tree crop only) in main plot and three levels of fertilizer doses and seed rate viz; T1 recommended dose of fertilizer and seed rate, T2-T1 + 25% more nitrogen then recommended dose of fertilizer and T3-T1 + 25 % more seed rate than recommended dose of 3 1 seed rate in sub plot replication in 5 times. 75% pruning recorded significantly higher yield attributing characters as compared no pruning. Open condition recorded higher grain yield (27.3 q ha-1), straw yield (41.8 q ha-1) and harvest index (39.5%) as compared to different pruning treatment' 75% pruning gave higher grain yield (24.4 q ha-1), straw yield (40.6 q ha-1) and harvest index (37.5%) as compared to other pruning treatment. No pruning recorded significantly lowest grain yield, straw yield and harvest index. At age of 16 years, Dalbergia Sissoo in 25% pruning gave higher tree height (11.92 m), dbh (22.71cm), cylindrical volume (217.27 m3 ha-1), and stand biomass (167301 kgha-1). In managed agroforestry system wheat + D. Sissoo in 25% pruning gave significantly highest monetary return (` 79421 ha-1) as compared to no pruning (` 67506 ha-1), crop alone (`39714 ha-1) and tree alone (` 40243 ha-1). In agronomical management practices 25% more nitrogen then recommended dose recorded significantly higher monetary return (` 69616 ha-1) than recommended dose of fertilizer and seed rate (`59544 ha-1).

Subject: Estimation of Variability, Heritability, Genetic Gain and Correlation in Clones (Grafts) of Kachnar (Bauhinia variegata L.)
Keywords: Progeny Test, Growth Traits, Genotypes, Clone, Genetic Parameters, Correlation.
Abstract: Thirty two genotypes of Bauhinia variegata were evaluated for growth characteristics, mineral nutrients and proximate principles after four years in a previously raised progeny trial in the experimental field of the department.. Thus top eighteen selected genotypes were grafted separately on seedling stock of the same species and a clonal seed orchard was established which consisted of eighteen clones raised in RBD with three replications. After four years the observations were recorded on plant height, basal diameter, leaf width, leaf length, number of branches, petiole length and green leaf yield in each ramet of clones. Significant differences among clones were observed for different morphometric traits. Various genetic parameters and correlation coefficients for different growth characters were determined. The highest per cent GCV (33.20) and PCV (36.02) as also heritability (84.95) were exhibited by green leaf yield while maximum GA (3.23) was noticed in leaf width. The highest percent GG (61.86) was recorded for green leaf yield. Significantly positive correlations were observed between plant height and basal diameter (0.6086), plant height and green leaf yield (0.8461), basal diameter and green leaf yield (0.6924), leaf width and leaf length (0.6490), leaf width and green leaf yield (0.5688) and leaf length and green leaf yield (0.4225).

Subject: Durability and Dimensional Stability Assessment of Chemically Treated Harvested Bamboo (Bambusa balcooa Roxb).
Keywords: Dimensional Stability, Anti Shrink Efficiency, Strength Properties, Termite Resistance.
Abstract: The present experiment was carried out to study the durability and dimensional stability of the chemically treated bamboo (Bambusa balcooa). The efficacy of the preservative chemicals for the treatment of bamboo samples was evaluated in ground contact against termite and fungus. The bamboo samples treated with boric acid (BA), copper acetate (CA), phthalic anhydride (PA), sodium salt of triet Helen tetramine dithiocarbamate (triendtc) and kerosene showed higher dimensional stability efficiency in terms of anti shrink efficiency (ASE), bulk coefficient (BC) and weight percent gain (WPG). The strength properties such as modulus of rupture (MOR) and modulus of elasticity (MOE) of treated bamboo samples showed higher values than the untreated bamboo sample. The thermal behavior of the treated and untreated samples were studied using thermogravemetric (TG) and differential thermogravemetric (DTG) techniques and found that the treated samples were thermally more stable than the untreated one. The treated bamboo samples could resist termite and fungal attack which extend the service life.

Subject: Assessing Land-use Land-cover Dynamics (1990-2030) in Pathri Reserve Forest using Geospatial Technology
Keywords: Pathri Reserve Forest, Land Use Land Cover, Geospatial Technology, Markov Modeling.
Abstract: Forests being a dynamic feature are prone to changes which may be either positive or negative. The present study has been taken to monitor Land use land cover (LULC) dynamics in Pathri reserve forest over the past three decades (1990, 2000 and 2010), before and after de-reserving some part of this forest in view of the rehabilitation of Tehri dam evacuees. Landsat TM data has been used to generate maps on 1:50000 scale using visual interpretation. The three time period forest vector layers were used for predicting the forest cover for the periods 2010 and 2030 using Cellular Automata (CA) Markov model. The analysis reveals that out of 17.31km2 in 1990, only 2.62 km2 of area was left as dense forest in 2010, while the remaining area was degraded to open forest and scrub. About 13 km2 area of water bodies and wetlands in the study area reduced to 3.4 km2 in two decades indicates demand for intensification of agricultural besides the pressure for fuel wood collection and uncontrolled grazing. This loss of forest over the decades can be attributed to the Rehabilitation Policy, 1998 of the Government of Uttarakhand to resettle the Tehri dam evacuees and relocation of Gujjars, a nomadic community to an 8 km2 patch at Pathri rehabilitation site. Human interventions as well as signs of disturbance such as lopped off trees, presence of invasive species such as Ipomea spp. and Clerodendron spp. could be the causative factors. From the present LULC dynamics and projection for 2030, it is evident that the Pathri reserve forest continues to be under pressure from anthropogenic activities.
