Screening of twenty-four candidate plus trees from naturally available Pongamia pinnata genetic resources was carried out to elucidate the genetic variation and relationship of pod and seed traits on germination capacity to select the best planting material for higher productivity. The experiment conducted at Forest Research Centre, Institute of Forest Productivity Mandar, Ranchi during 2005-2006. Variability studies reveled that, genotype CPT-19 recorded maximum values for six traits viz. pod length (65.64 mm), 100-pod weight (542.35 g), 2D surface area (351.18 mm2), seed length (27.93 mm), 100-seed weight (202.89 g) and total oil content (44.33%). However, maximum pod thickness (12.72 mm), seed length (17.49 mm), pod-seed ratio (2.89) germination capacity (94.67%) was recorded by the genotype CPT-6. The phenotypic and genotypic coefficients of variations were also close to each other for all traits, but 100-pod weight and 100-seed weight exhibited higher phenotypic coefficients of variation and genotypic coefficients of variation than the other traits. Estimates of broad sense heritability ranged from 0.82 (for seed length) to 0.98 (for 100-pod weight), genetic advance as percent of the mean ranged between 12.30% and 46.04% with seed length giving the lowest value and 100-pod weight giving the highest value. Germination capacity exhibited positive significant correlation with pod width, 100-pod weight, 2D surface area and seed width at both genotypic and phenotypic level. However, pod length, pod thickness and 100-seed weight expressed positive significant correlation only at genotypic level. Path analysis of pod and seed traits revealed that, the 100-pod weight (0.909) is the most pronounced character contributing directly to germination capacity followed by seed length (0.785) and pod length (0.324). In conclusion, the results revealed the existence of substantial genetic variation, which can be utilized for genetic resources conservation in gene bank and further tree improvement programmers of the species.

The nature of damage, seasonal incidence, developmental period and morphometrics of Cochlochila bullita (Stål) (Heteroptera: Tingidae) were studied on Ocimum sanctum L. in Jharkhand province of India. The infestation of C. bullita started in June and continued until December on O. sanctum. The highest population of C. bullita per twig was found to be 63.8 in 2011 and 71.2 in 2012, in the months of August and September, respectively. The highest per leaf population of C. bullita was observed in the month of September in both years. The adults and nymphs of C. bullita were found feeding gregariously on the tender leaf and shoot, and laid eggs - mostly single, but sometimes in groups. Pre-oviposition period, oviposition period and egg incubation period of the bug were 3.37, 15.56 and 6.06 days, respectively, whereas the nymphal period was 11.50 days and the adult period was 21.18 days. This is the first report of feeding of C. bullita on O. sanctum from Jharkhand, India. © 2013 Springer Science+Business Media Dordrecht.

The aim of the present study is to develop an environment-friendly method to convert orange pulp wastes to Carboxymethyl cellulose (CMC) by homogeneous substitution. Carboxymethylation of Orange pulp treated with alkaline PEG solutions was investigated and characterized by means of TGA, DSC, XRD and SEM and compared with commercial CMC. The TGA data reveals that shifting of peaks was observed towards lower temperature with increase in monochloroacetic acid (MCA). SEM studies showed greater blending of particulate powder with increasing MCA content. The crystallinity of synthesized CMC was found to be lower than the commercial CMC. Finally, the cellulosic materials were evaluated for the formulation and dissolution studies of prepared tablets. Dissolution release studies shows that synthesized cellulose (CMCOP5, CMCOP8, CMCOP11) release up to 70.1 ± 0.04%, whereas the commercial CMC 78.184 ± 0.07% in 8 h respectively and thereby suggests that it may be used in delayed drug delivery and targeting drugs to the colon. The synthesized CMC from orange pulp may be used as substitute for the commercial CMC. © 2016 Elsevier B.V.

A total of 24 candidate plus trees (CPTs) of Pongamia pinnata (L.) Pierre. were selected to elucidate their variation and diversity based on thirteen quantitative traits (4 pod traits, 6 seed traits of parent trees and 3 progeny traits) at Forest Research Centre, Institute of Forest Productivity - Mandar, Ranchi district during 2005-2007. The results show that, CPT-19 had maximum for seven traits viz, pod length (65.6 mm), 100-pod weight (542.4 g), seed 2D (two dimension) area (351.2 mm2), seed length (27.9 mm), seed breadth (17.4 mm), 100-seed weight (217.9 g) and plant height (164.3 cm). The traits, 100-pod weight and 100-seed weight had a high heritability (98.4%, 96.9%) accompanied with high genetic advance (46.0%, 34.9%). There is a positive significant correlation between 100-pod weight and 100-seed weight traits at both genotypic and phenotypic levels with plant height, collar diameter and volume index at 30 MAS (months after sowing). Volume index expressed a moderate heritability (47.4%) accompanied with high genetic advance (48.4%), indicating that the character is governed by additive gene effects. In divergence study, 24 accessions were grouped into 6 clusters on the basis of non-hierarchical euclidian cluster analysis. The genotypes in cluster IV (CPT-5, CPT-6, CPT-7, CPT-12, CPT-16, CPT-18, CPT-22) and cluster III (CPT-4, CPT-8, CPT-9, CPT-20, CPT-21) were most heterogeneous and can be best used within group hybridization. The wide diversity exists between the cluster V and II, followed by cluster II and I and crosses between CPTs of these clusters may result in substantial segregates. It is revealed that the existence of substantial variation and diversity can be utilized for genetic resource conservation and further tree improvement programmers of the species. © 2011 Northeast Forestry University and Springer-Verlag Berlin Heidelberg.

Callusing and root induction in air layering was evaluated aiming at evolution of procedure for mass clonal propagation of mature ortets of five tropical broadleaf species differing in their potential for adventitious root formation in shoot cuttings as: Anogiessus latifolia < Boswellia serrata < Dalbergia latifolia < Gmelina arborea < Dalbergia sissoo. Two experiments were conducted in rainy season during consecutive years; without application of growth regulators in the first year and with growth regulators (T1 - water, T2 - 100 ppm indole-3-acetic acid, T3 -100 ppm thiamine- HCl and T4 -combination of T2 + T3) in the next year. Air layered branches were detached from the trees to record percentage of alive airlayers, callusing and rooting (%) as well as root number and root length. Response to air layering was found to be highly variable in five tree species but appeared to be feasible procedure for clonal propagation of mature ortets of B. serrata and D. sissoo with 100% (in auxin + thiamine treatment) and 83.3% (in auxin treatment) success, respectively. Maximum callusing (%) was found in D. latifoliawhile no callusing was observed in D. sissoo, which is most easy-to-root among all five species. Callus formation impedes adventitious rhizogenesis in air layers as significant negative correlation of callusing (%) and adventitious root formation was recorded in air layers of five tropical broadleaved tree species. Application of exogenous auxin alone or in combination with thiamine circumvents callusing to ensure direct development of roots for successful air layering.

Medicinal plants play an important role in disease management and livelihoods of people worldwide. In recent years, the growing demand for medicinal plants has accelerated over exploitation of valuable resources by unscientific and destructive manner without considering sustain ability and quality issues. As a consequence, the quality of both raw material and finished products has become important concern for herbal/pharmaceutical/nutraceutical/cosmeceutical industries and the public alike. Moreover, medicinal plant collectors are not getting remunerative value for their produce because of poor quality (due to wrong identification, immature collection, poor processing, inadequate storage, adulteration etc.). Good collection/harvesting practices of some important medicinal plants i.e., Aonla (Phyllanthus emblica), Baividang (Embelia tsjeriam-cottam), Baheda (Terminalia bellericd), Gudmar (Gymnema sylvestre), Sarpagandha (Rauvolfia serpentina) and Kalmegh (Andrographis paniculata) have been standardized for tropical climate of central India. The quality (active ingredients) of above plants was also evaluated. It is evident from our study that the medicinal plants harvested at right time of maturity following Good Field Collection Practices (GFCPs) possess better quality in terms of active ingredients concentration. Adoption of GFCPs and quality evaluation of medicinal plants will have positive impact on resource conservation, socio-economic status of community, quality of produce, economic returns and marketing. To achieve these, R and D institutions may act as nodal centers for quality evaluation and dissemination of GFCPs to the collector/growers of medicinal plants to augment utilization and get premium price of their produce. © 2014 Academic Journals Inc.
