Keywords: Pinus radiata, Thermal treatment, Termite resistance, Neem seed oil, Linseed oil, Unifed thermal and Neem seed oil treatment.
Abstract: The present study was conduct to investigate the influence of unified thermal and neem seed oil treatment on the termite resistance of Pinus radiata D.Don wood. For this purpose, wood was heated at different temperature i.e. 180, 200 an 220?C for periods of 30, 60 and 90 min in an inert atmosphere and then submerged in neem seed oil (diluted to 25 % with linseed oil) for 24 h. Thermal treatment at similar temperatures an time duration, Dip treatment in 25 % neem seed oil and 100 % linseed oil were also performed on wood to find out the role played by each component. Results revealed that untreated Pinus radiata wood is susceptible to termite and very heavy attack in ground contact was observed. Thermal treatment alone had not efficiently protected wood against termite. Neem seed oil increased resistance of wood against termite attack and only slight to moderate attack of termite was recorded in treated wood. Unified thermal and neem seed oil treatment was found effective in controlling termite attack. It was further observed linseed oil was not efficacious of reducing termite attack on wood.

Keywords: 2C nuclear DNA; Cardamom; Elettaria cardamomum; Flow cytometry; Genome size.
Abstract: The relative 2C genome size and total number of base pairs of small cardamom (Elettaria cardamomum Maton) was determined using flow cytometer. Seven accessions of cardamom were included in the present study. Zea mays.L.CE-777 (2C=5.43 pg) was found to be the most suitable reference standard. Samples for analysis were prepared following the two step procedure described by Otto and involving propidium iodide staining. The fluorescence intensity of 5000 particles was recorded. The mean amount of 2C nuclear DNA of the cardamom sample was calculated as 2.84 pg. Conversion between DNA content and genome size (1 pg DNA=980 Mbp) indicate that the diploid genome size of cardamom is 2783 Mbp. This is the first report of DNA content and genome size in cardamom. Low variation in genome size has been observed for various germplasm accessions including wild, released varieties and landraces.

Abstract: For obtaining contamination free cultures, the most important step is sterilization of explants. In the present study, the sterilization procedure was standardized for Chimonobambusa jaunsarensis syn. Arundinaria jaunsarensis. Comparison was done between three important sterilants, HgCl2 (0.05 %, 0.1 % and 0.15 % w/v) for 5, 10 and 15 minutes; NaOCL (5%, 10 % and 15 % v/v) for 5, 10 and 15 minutes and H2O2 (5 %, 10 % and 15% v/v) for 5, 10 and15 minutes, supplemented with few drops of Tween 20 per 100 ml. Sterilized explants were inoculated on MS medium supplemented with 1 mg/ 1 BAP to evaluate the response of different sterilants. The present study has been done to standardize the sterilization method for explants of Chimonobambusa jaunsarensis for in-vitro propagation intended for its propagation using different types of sterilizing agents by varying their concentration and duration of exposure. Result showed that amongst the three sterilants i.e. Mercuric chloride (HgCl2).Sodium hypochlorite (NaOcl) and Hydrogen peroxide (H2O2) HgCl2 was found better for controlling the infection with maximum number of healthy cultures.

Subject: Ecosan (Ecological Sanitation) based Agroforestry for Boosting Rural livelihoods
Keywords: Livelihoods, ECOSAN, Agroforestry
Abstract: The earlier ' Nirmal Bharat Abhiyan ' (NBA) and the recent ' Clean India Mission ' , for promotion of safe sanitation has been the only driving force for this article, which pertains to synergistic union of ECOSAN (Ecological sanitation) with Agroforestry. Various constraints and limiting factors affecting rural livelihoods have been elaborated to highlight the important of this issue, which advocates for the use of recycled human excreta (urine and faeces) for optimizing the land resource use efficiency through Agroforestry. The benefits, relevance and intricacies of ECOSAN have been reproduced to sensitize the stakeholders for its adoption in Agroforestry systems.
Suitable tree-crop combinations have been recommended for the different regions of India. The examples and database of enhancement of farm production through use of nutrient rich Human excreta, recycled by ECOSAN, as manure have been reproduced through comparative studies of human excreta vis-?-vis conventional fertilizers. This recommendation for innovative Agroforestry is expected to be an incredible cost-effective option to boost the rural livelihoods of India, which suffer a lot due to multidimensional setbacks. Keeping in view the taboos for use of human excreta, only three categories of Agroforestry Systems have been recommended under: Silvi-pastoral, Horti-pastoral and Silvi-horti-pastoral systems. It is expected that the proposed synergistic integration of Agroforestry with ACOSAN would revolutionize the rural livelihoods besides upholding the dignity of rural populations by ensuring a hygienic an ecofriendly sanitation system. The free inputs for Agroforestry would substantially boost rural economy as well by cutting down the expenses of fertilizers.

Abstract: An experiment was conducted at National Research Center For Agroforestry, Jhansi (situated between 24?11 to 26? 27`N latitude an 78?17` to 81?34`E longitudes, at an elevation of 300 amsl), to study the effect of seed source of Pongamia pinnata, on germination and seedling growth, which can be used in genetic improvement programme. The ten sources/provences were selected from Uttar Pradesh (Jhansi, Babina, Matateela, Faizabad), West Bengal (Kalyani, Jhargram, Haldia), Haryana (Hisar), Karnataka (Dharwar) and Andhra Pradesh (Hyderabad).The seeds from these sources were obtained either through survey or through coordinating centres of All India Coordinated Research Project on Agroforestry (AICRP on AF).Comparison of morphological characters among different seed sources revealed, that the seed source of Jhargram exhibited its superiority in seed and pod size. Seed length was found maximum in the seed collected from Kalyani. The germination and related parameters indicate that the provenance of Kalyani gave the significantly higher value for germination percentage, germination value and Germination energy index. The seedling growth parameters indicated that the provenance of Dharwar exhibited maximum growth and biomass of Pongamia pinnata in comparison to other provenance/sources. Overall results exhibited that the seeds collected from West Bengal (Kalyani and Jhargram) performed constantly in term of germination, growth and biomass at nursery stage.

Abstract: Growth and Biomass of three important energy plantation tree species viz. Acacia auriculiformis, Cassia siamea and Eucalyptus hybrid was studied in three districts (Deoghar in subzone IV, Ranchi in sub zone V and East Singhbhum in sub zone VI) of agro climatic zone VII (Eastern plateau and hill region) of Jharkahand, India. The measurement was taken during 2011-12, when plantation reached at an age of four years. The comparison of growth performance in terms of survival percent, plant height, diameter and total biomass of tree were done. Among three species, Eucalyptus hybrid was better as compared to other two species in terms of survival, growth and biomass. Survival per cent of all three species were found more than75%.Growth performance (height an diameter) of Eucalyptus hybrid was found better as compared to other species. The tree height and diameter of Eucalyptus hybrid was recorded maximum11.42m and 9.14cm followed by Acacia auriculiformis (5.54m and 4.69 cm).and Casia siamea (5.03 m and 3.85 cm). The data for fresh biomass of different above ground parts (bole, branches, leaves and barks) and below ground parts (roots) were also collected. The result indicated that Eucalyptus hybrid (average 307.69 kg/tree) had maximum fresh biomass as compared to other two species, whereas below ground maximum fresh biomass obtained by Acacia auriculiformis (average 19.33 kg/tree) followed by Casia siamea (average 14.61 kg/tree) and the minimum fresh biomass of rot obtained by Euclyptus hybrid (13.45 kg/tree.).

Abstract: Tecomella undulata is a medicinally, ecologically an economically important timber species of hot arid regions of India and Pakistan. No methods are available for its vegetative propagation therefore, micropropagation was standardized using explants collected from mature trees. Sterilization an establishment of explants remains the most important step for successful micropropagation. In the present study differences in per cent aseptic (72.0 to 37.33) and necrotic (25.33 to 4.0) cultures as well as morphogenic response were observed when explants were collected in different months from mature trees of T. undulata. Per cent bud break (72.0) as well as number of shoots induced (3.04) was maximum in the month of April while explants collected during winter months (November-February) showed poor response. Callusing on explants was maximum during autumn months and decreased in explants collected during spring season. Antioxidants namely ascorbic acid (50.0 mg/l), citric acid (25.0 mg/l 0and arginine (25.0 mg/l) when added to the establishment media (MS+10?M BAP) reduced extent of callusing).Induced shoots were successfully multiplied on SH medium supplemented with 5.?M each of BAP an kinetin while rooting was induced on 10?M IBA supplemented SH medium followed by hardening an acclimatization of rooted shoots.

Abstract: The study was conducted to note the phytodiversity and its distribution along range of 2850 m to 3400 m on both sides of Chattergalla ridge in Jammu and Kashmir, north western Himalayas. The ridge displays a typical conical cross section with characteristic vegetational diversity and distribution along the opposite aspects with more or less same degree of slope inclination. During the investigations, 180 species belonging to 139 genera in 54 families were recorded from the study area, of which131 species were observed common, while 161 species were exclusively found in northern and 150 in southern aspect, respectively. The number of deciduous species was relatively higher than evergreen species with more concentration along the northern aspect owing to micro-climatic fluctuations. The species richness and diversity revealed a decreasing trend with the rising elevation. The biodiversity of the region is slowly eroding owing to uncontrolled grazing and ruthless extraction of medicinal plants.

Subject: Tree diversity and structure of a tropical dry deciduous forest in Sri Lankamalla wildlife Sanctuary
Keywords: Dry deciduous forests, Rank abundance curve, Importance Value index, Population structure, Sri Lankamalla wildlife sanctuary.
Abstract: Tropical dry forests are the dominant and threatened forest ecosystems in India. Species richness, diversity, importance value index of tree species of tree species were analysed in SriLankamalla dry deciduous forest of southern Eastern Ghats. All trees>30 cm gbh were enumerated in plain and hill slopes of the sanctuary in two hectare area. A total of 1994 tree individuals that belongs to 35 families and 73 genera were recorded. Euphorbiaceae was the dominant family comprising of 11 species. The Shannon index value of 2.9 indicates a moderate level of species richness. Few tree species dominated the forests, the top twenty species had recorded 77% of tree individuals an 54 % comprised of density of less than ten individuals per ha. Pterocarpus santalinus, Hardwickia binata and Anogeissus latifolia were the dominant tree species. The population structure of the dominant tree Pterocarpus santalinus has abundance of individuals in lower size classes probably due to selective logging. The topographical features such as plain and hill slope areas has helped increasing the tree diversity.

Subject: Genetic improvement in Pongamia pinnata
Keywords: Bio-diesel, Oil content, Plus tree, Progeny, Storing
Abstract: Pongamia pinnata has become an extremely important tree species for extraction of oil for bio-diesel. The study conducted on various stages of storage revealed that the freshly harvested seeds produce maximum oil of 35.27 %, which reduces substantially with storing duration. The seeds stored at 4?C for six months were found to have 33.34 % oil. The same was further reduced when seeds were stored at temperature for six months to 32.49 %.The oil content also varies from progeny to progeny an progeny 81 was found to contain highest oil content of 41.43 %.Therefore, utilization of seeds of such genotypes for bio-diesel could play significantly important role in bridging the gap between demand and supply.
