Abstract: Salmonella/microsome reversion assay was used as a biological parameter for monitoring the toxicity of common effluent treatment plant (CETP), Mandia road industrial area, Pali catering to textile industrial areas in Pali, Rajasthan. The influent and effluent water of CETP, surface water (Bandi river) and underground water were tested using Ames bioassay. The results showed presence of mutagens in surface water of Bandi river and the underground water in Pali. Further, comparison of mutagenicity of CETP influent and effluent water revealed that the treatment method employed at this plant has failed to remove mutagenic substances present in Pali textile wastewate. The study also showed that Ames assay is an important tool in genotoxic studies because of its simplicity, sensitivity to genetic damage, speed, low cost of experimentation and small amount of sample required. Further Ames assay, as seen from the results of this study, can be used as a monitoring tool for not only CETPs but also for other water resources. The outcomes of the Ames assay demonstrated its performance as a sensitive, cost-effective and relatively rapid screening tool to assess the genotoxic potential of complex environmental samples.

Abstract: Santalum album Linn is partial root parasite in nature and hence requires host plant for its regeneration and establishment. A study was conducted to observe the regeneration status under different plant ecosystems. Distribution of natural regeneration of sandal was found to be statistically significant among different ecosystems situated. The overall regeneration was highest in medicinal plant garden, followed by natural forest and bamboo plantations. Considering the different stages of plant growth, plants (seedlings) belongs to the class less than one meter height showed maximum count in all the ecosystems with overall percent of 69.9, followed by plants (saplings) belongs to 1 to 2 m height (26.0%) and least in plants with more than 2 m height (4.2%). The overall result indicated that, regeneration and establishment of sandal is greatly influenced by availability of seed bearing mother plants in the area, seed dispersal agents, host plants and their nature, fire, grazing and browsing, site conditions and degree of protecction provided.

Abstract: The present study was conducted taking quality seeds of selected plus trees of Gmelina arborea in four different size of root-trainers, viz., T1 (150 cc), T2 (250 cc), T3 (350 cc) and T4 (500 cc). Each root-trainer size was treated as a separate treatment and each treatment replicated three times. Each replication had 10 seedlings of 3-leaf stage in Uniform potting media. At the end of three months, four seedlings were selected randomly for measurement of growth parameters and biomass studies. Total seedling height, collar diameter, shoot biomass, root biomass, tap root length and number of lateral roots were recorded. Sturdiness quotient, shoot-root ratio and seedling quality index were calculated. The results of the present study show that root-trainer size had significant effect for all growth parameters. Treatment average difference for all growth parameters except number of leaves, which was maximum in T4 and minimum in T1 observed. The sturdiness and seedling quality have direct and positive relationship with root -trainer size.

Keywords: coppiced trees, bio-energy plantations
Abstract: The study was a part of biomass research programme on selection and improvement of fast growing leguminous tree species suitable for short rotation bio-energy plantations on sodic soil sites (ph 8.6 to 10.5) It included selection of promising seed sources and plus trees followed by cloning of selected in Leucaena leucocephala (K8 variety) for high biomass productivity on sodic soils. Evaluation of field performance of five seed sources revealed best performance of plants in Madurai seed source after 3-year of growth while plants of Oxford seed source showed poor performance as compared to plants of other seed sources investigated during present study. Intra-specific variations were observed at individual tree level in an even aged 8-yr-old population. Several plus trees (30) were identified on the basis of phenotypic superiority in plant height, trunk thickness and biomass productivity. Successful populations (gene pools) and individual plus trees were multiplied vegetatively using coppice shoots and conserved as a future resource for production of site adapted quality germplasm for plantations on sodic wastelands. The study would help in establishing site adapted germplasm for optimizing gains in future afforestation programmes on degraded forest and community lands.

Keywords: Noni (Morinda citrifolia L.), Growth and development, flowering and fruit setting, Ambient temperature and relative humidity
Abstract: High valued medicina plant of Noni (Morinda citrifolia L) were grown in Varanasi (25018 ' N 83001 ' E) during 2007-09 to assess the agro-climatic potential on the crop cultivation in sub-tropical and dry sub-humid conditions. The germination and emergence of noni seeds at an ambient temperature ranged between 23 and 360C of September conditions has been studied. Highly signficant linear relationships between the leaf tip appearance number (Y) and the heat units (X) was developed: Y = 0.0038 X + 0.4823 with cc = 0.998 (significant at 1% level) for the seedling stage of the crop after the emergence. This indicated that the seedlings took about 2540Cd of growing degree days (GDD) for producing each new leaf tip before its transplantation. The, agro-meteorological measurements visualised that the noni seedlings growth ceased when ambient temperature was either <120C or >400C under Varanasi conditions.
Study also indicated that the leaf tip production was the fastest (1560Cd leaf-1) on the plant under partial shading treatment (T2) followed by zero shading (T1) treatment (1770Cd leaf-1) and partial shading with compact soil (T3) treatment (2010Cd leaf-1) plants, after the transplantation. Height of the main shoot (MS ) of the plants has increased rapidly and measured to highest (4.25 m) again under T2 treatment followed by 3.0 m under T1 treatment and lowest (2.95m) under T3 treatment at the end of second season (Novermber 2009).
Growing period for the noni crop was found nine months (270 days) from March to November. The plant took about 75 to 90 days time and at least 1250 to 1600 0Cd of GDD for proper fruit development and to reach at semi ripening stage in Varanasi area.

Keywords: Populus ciliata, kanamycin sensitivity, regeneration, transformation
Abstract: Kanamycin sensitivity studies were conducted in leaf and petiole tissues of Himalayan poplar to investigate the suitability of kanamycin resistance as a selectable marker for genetic transformation. Increasing concentrations of kanamycin i.e 10, 20, 30, 40 and 50mg/l was given to find out the minimum dose of kanamycin required for the selection of putative transformed cells during genetic transformation. A decrease in fresh weight in leaf and petiole explants was observed with the increase in kanamycin concentration. At 50 mg/l kanamycin, callus formation and shoot regeneration was blocked and the explants turned brown and started dieing. The higher tolerance level of leaf and petiole tissues of Himalayan poplar up to 50 mg/l kanamycin concentration indicated that this concentration of kanamycin would be the most useful for selection of npt-II gene transformed leaf and petiole tissues of Populus ciliata.

Abstract: Eucalyptus vegetative mass production has been advanced through the adoption of many improved methods. The suitability of vegetaive mass propagation using minicuttings derived from the minihedges grown in the sand beds was evaluated. The study reveals the superiority of this technique over the regular stem cuttings from the open clonal multiplication area. The minicutttings of Eucalyptus camaldulensis (ITC 413, TNPL 103) and Eucalyptus tereticornis (ITC 3, TNPL 106) clones recorded more than 80% survival in the mist chamber, whereas the stem cuttings from the open CMA of the same clones recorded only 50% survival. The use of growth substances wee completely eliminated in the minicuttings. Among the treatment periods T2 (21 days in the mist chamber) proved to be highly effective for the Eucalyptus mass production through the mini cutting method. Except shoot length the other parameters like survival percentage in the mist chamber, 50% shade house, root length and number of lateral roots was more in T2 compare to other treatments. The juvenility and nutrient status of the mother plants influences the survival ability of the minicuttings in the mist chamber. The present study reveals the suitability of minicutting clonal production method for E. camaldulensis and E. tereticornis clones in the Indian condition.

Abstract: Survival and growth of Jatropha curcas was examined in relation to slope gradient and rainwater harvesting treatments with a view to use this species in revegetation of degraded hilly area with its socio-economic benfits. Varying slopes were < 20%, 10-20% and >20%, whereas rainwater harvesting treatments were control (CL), contour trench, (CT), Gardonie (G), Box trench (BT) and V-ditch (V). Soil water content (SWC) was greater (P<0.05) < 10% area and decrease in order <10% <20% <10-20% slope areas. SWC was lowest in the CL plots, whereas it was highest in Gradonie plots in August. The increase in SWC over control was by 16% and 24% in August 2006 and 2007, respectively. SWC was highest in CT in June 2006 and in BT in June 2007, and the improvement in SWC resulted from rainwater harvesting was by 51% and 15% in the respective treatments influencing survival and growht of J. curcas. The lowest survival in >20% slope area indicated its susceptibility to water stress, further supported by the highest growth in BT plots with the highest soil water. Plants were tallest (p<0.05) in <10% and smallest in >20% slope area. The plants growing along the contour trench were tallest (p<0.05), whereas plants growing in the control plots were smallest (p < 0.05) suggesting the beneficial effects of water harvesting on the growth of J. curcas in degraded areas. Conclusively Jatropha curcas can be used to restore degraded hilly tract utilizing rainwater harvesting.
