Keywords: Genetic variability, Heritability, Genetic gain, Genetic correlation, Age-age correlation, Candidate plus tree, Eucalyptus hybrid
Abstract: A trial of progeny of 11 Candidate Plus Trees (CPTs), 2 sources of clonally propagated planting material and one source of clonal seed orchard seedlings was conducted as Thathlan, Hoshairpur (Punjab) to assess the growth performance and to evaluate genetic variability and correlation among different growth characters for three consecutive years. In all quantitative characters assessed, clonal material viz. T9 , T1 and T10 gave the best height, diameter and clean bole. The heritability values for height (0.67 to 0.71), diameter (0.50-0.59) and clean bole (0.64-0.76) were high genetic gains upto three year of observations.The findings suggest that these characters are governed by the genetic make up of the trait and attribute significantly to the phenotypic performance at early stage giving ample opportunity for selection of the outstanding genotypes. Similarly, straightness exhibited high heritability varing from 0.55 to 0.64 during the first and third year respectively. The heritability estimate for axis persistance ranged from 0.46 to 0.56 with high genetic gain of 21.10 to 14.63 in year one and three respectively. The significant genotypic and phenotypic correlation found between height and diameter suggests that improvement in one character will be accompanied by another. Also a high positive significant correlation was exhibited in year one to three. A highly significant age-age correlation for height and diameter growth indicate that selection based on these two characters can be done at the juvenile stage to achieve more gain per unit time.

Abstract: Acorus calamus commonly known as Sweet flag is a medicinal herb, effectively used in treating variety of illness. The chemicals were fractionated from rhizome of Acorus calamus and antimicrobial properties of Hydrocarbon and Beta asarone were studied. Acorus calamus were collected from Nilgiri wetland areas. The components of rhizome of Acorus calamus were separated using column chromatography. Hydrocarbon and Beta asarone parts were eluted from the column and tested for its antimicrobial assay. Antibacterial activity of fractionated beta asarone inhibited the growth of Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Salmonella typhi and Listeria monocytogenes. There is no antibacterial activity in fractionated hydrocarbon. The determination of antimicrobial activity of Acorus calamus reveals that beta asarone is responsible for antimicrobial activity and this can be used in future for preparation of drugs.

Keywords: Fly ash, Ferns, Diversity indices, Management
Abstract: The study site was thermal power station, Kanti and nearby locality (District Muzaffarpur , Bihar), having Gangetic plain topography with fertile soil. But fly ash deposition of thermal power has reduced the soil fertility of nearby area and consequently local farmers were vexed by adverse effect on crop yield. In similar condition ferns were found luxuriantly growing inside and outside the campus of thermal power without any visible phytotoxic symptoms. In context of the above, during present study metal content and physico-chemical properties of the fly ash site and soil samples of natural forest site of Balmikinagar (reference site) were studied. Community structure (frequency, density, abundance, and IVI) and several diversity indices including population density, concentration of dominance, heterogeneity, equitability, Shannon Wiener ' s diversity index of ferns of both fly ash site and reference site were studied. Effect of fly ash on photosynthetic pigments were studied and compared with reference site. Results showed that fern communities existing on fly ash site perform better than reference site even in presence of high metal content in fly ash. As ferns grown on fly ash site show slight reduction in chlorophyll content but no visible toxicity symptoms and have higher population distribution, it indicates the possibility of management of metal loaded wastelands with metal accumulator fern species.

Abstract: Thirty-five genotypes of Tamarindus indica L.were evaluated to study variability and character association for various pulp biochemical traits as scope for further improvement. Variability studies revealed that none of the genotypes recorded maximum for more than one pulp biochemical trait. Maximum anthocyanin pigment and total tartaric acid was expressed by TI-32 (1.566 mg/100g) and TI-5 (20.60%) respectively. Total phenol and anthocyanin pigment expressed high heritability coupled with high genetic gain. Correlation studies indicated an inherent association between the characters with most of the traits having negative correlation with total tartaric acid content. Pigment anthocyanin showed negative and highly significant correlation with moisture content genotypic level. In path coefficient analysis total sugars, total phenol, protein, ash, moisture, total soluble solids showed positive direct effect on total tartaric acid content.

Abstract: Light textured soils having low organic matter and nutrient content in the soil are prone to nutrient deficiencies in the plants growing on such soils. Zinc deficiency symptoms were observed in poplar plantations and nurseries, having soil deficient in organic matter and nutrient contents in Ludhiana District of Punjab on such soils. The deficiency was exhibited by development of irregular interveinal chlorosis of recently matured leaves along the margins that extends towards base of leaves. The deficiency was ameliorated by soil application of 25 g/plant Zn (through ZnSO4
.7H 2 O) in 1 year plants, 40 g/plant Zn in 2 years old plants and 30 kg/ha Zn in 4.5 years old plants. Application of 20 kg/ha Zn was sufficient for eradicating Zn deficiency in nurseries. Deficiency could be cured by 5-6 weekly sprays of 0.5 percent ZnSO4.7H 2 O(alongwith half the quantity of unslaked lime) in the solution volumes of 11/tree for one year old trees, 21/tree for 2 year old trees and 250 l/ha for nursery. The micronutrient (except Fe) content of the recently matured normal leaves (Zn :29.2 - 38.6 mg kg -1)was higher than the deficient leaves (Zn :25.2 - 28.4 mg kg -1) taken from same position on branch or stem of trees. It was suggested to apply Zn at the planting time of poplar that can meet the requirement of plants throughout its growth.

Abstract: The paper presents a comprehensive account on taxonomic identity, niche characteristics and distribution pattern of two important bamboo species of Meghalaya viz., Phyllostachys mannii Gamble and Sinarundinaria griffithiana (Munro) C.S.Chao & Renvoize. The altitudinal distribution of both the species and stand micro-environmental variables and soil characteristics indicate similar niche of the species. Both the species follow three-phase growth sequence. Based on the culm height, diameter and sheath morphology, it was concluded that Phyllostachys mannii, Phyllostachys assamica and Phyllostachys bambusoides are synonyms instead of being independent species as has been argued by many earlier workers. The distribution map of Phyllostachys mannii and Sinarundinaria griffithiana in Meghalaya shows extremely restricted distribution. Phyllostachys mannii has a restricted distribution world - wide and is confined to Meghalaya, Arunachal Pradesh and Nagaland of India, Yunnan province of China and Myanmar. Sinarundinaria griffithiana has also extremely restricted distribution in Arunachal Pradesh, Assam, Meghalaya, Mizoram, Nagaland and hills of West Bengal in India, Bhutan, Laos, Myanmar, China and Vietnam. Hence, based on their global distribution pattern, both the species may be termed as Endemic to South-East Asia.

Abstract: A study on soil water retention pattern under Chir (Pinus roxburghii), Khair (Acacia catechu), Eucalyptus (Eucalyptus hybrid) plantation and barren land was conducted in Mussoorie Forest Division (UK).Multivariate test showed that the mean soil retention changes across the different soil depth. The maximum amount of water was retained by the soils under Khair (356.90 to 879.40 k lit /ha) followed by Chir (286.73 to 913.13 k lit /ha), Eucalyptus (212.50 to 932.50 k lit/ha) and the least under barren land (116.27 to 824.03 k lit/ha) during the different months of the year. Good amount of water can be retained by the soils under plantation even in the drier months of April (255.20 to 393.27 k lit/ha ) to June (21.50 to 356.90 k lit/ha) as compared to barren land (116.27 to 221.0 k lit/ha). Even in the driest month of May, surface layer can hold 148.89% and over all entire profile by 217.73% more water under plantations as compared to barren land. In drier months, lower layers had higher retention as compared to upper layers. From July to September, soil profile retained maximum water because entire profile gets recharged due to rainfall.

Abstract: The present study deals with the computation of compositional pattern diversity in Kalsa watershed, Kumaun Himalaya. Compositional pattern diversity, which is a measure of complexity of the landscape, has been measured as mosaic diversity using affinity analysis. A total of four forest types were classified using satellite remote sensing data which include temperate broadleaf forest, temperate conifer forest, pine forest and degraded forest. The results of affinity analysis showed maximum value (6.53) of mosaic diversity for temperate conifer forest followed by the temperate broadleaf forest (6.49) , degraded forest (5.72) and pine forest (5.58). Pooled data from all the forest types when was taken for stratawise analysis showed maximum value (4.63) for herb layer followed by the shrub layer (3.51) and tree layer (2.50). High values (>3) of mosaic diversity indicated the presence of many underlying ecological gradients controlling the vegetation and high sensitivity of shrub and herb layer towards landscape complexity.
