Abstract: Bamboos have provided ample fuel to the human creativity. Without bamboos, it is impossible to think of rural life. In the past few years, the Government of India has been making incessant efforts to create an awareness among the masses for use of bamboos for protection against environment degradation because of fast growth the bamboos can attain, they have no parallel. Therefore, it is important to propagate and propularize some selected bamboo species which can be used as fodder for milch cattle, timber for house building and new shoots for food. The IHBT has taken up the responsibility of propagation and extension of one such edible Chinese bamboo. The present paper deals with bamboo seed germination and nursery management practices.

Abstract: Thirteen different provenances of Acacia nilotica were collected from different agroclimatic zones of India. Before sowing in the field, all the provenances were tested for seed mycoflora and germination. Large number of fungi belonging to different taxonomic groups were identified from seeds of A. nilotica. Aspergillus terreus showed the highest dominance in different provenances. The frequency of fungi was less in the provenances of Mandla and Jabalpur. A fungus Trichurus spiralis was recorded first time only on 6 provenances. The fungus was secreting the inhibitory substances, which possibly reduced the germination of seeds.

Keywords: Dendrocalamus brandisii, NAA, IBA, Vegetative propagation
Abstract: Dendrocalamus brandisii is a large size sympodial edible bamboo species of India and Myanmar with multifarious uses. A study was conducted to find out the effect of three seasons-summer, rainy and winter and three different positions of culmbase, middle and top and five different concentrations of two growth regulating substances-NAA and IBA on adventitious root induction in this species. Factor analysis of the observations revealed the significant influence of interaction effects (P=0.01) of season, position and growth regulating substance on growth attributes like height and collar girth of the sprouts, rooting percentage, number of roots and length of the longest root. Out of the three seasons, summer season and of the three positions, basal portion gave maximum rooting. Application of growth regulating substances increased the number of roots. Clustering of different treatment combinations identified the cuttings collected in summer season from basal portion of the culms treated with IBA 200 ppm as the superior treatment.

Abstract: Correlation and path coefficient studies were carried out in 15 seed sources of Simarouba glauca DC. collected from Tamil Nadu, Karnataka, Maharashtra and Orissa. Genotypic correlation coefficients were higher than phenotypic correlation coefficient in all the cases. Height and basal diameter had positive and highly significant correlation with volume index at both phenotypic and genotypic levels, in all the three locations viz. Mettupalayam, Tindivanam and Coimbatore. Height exhibited positive and highly significant inter correlation with basal diameter at both levels in all three locations. Path analysis revealed that height and basal diameter exhibited positive direct effect, while number of branches showed negative direct effect on volume index in all the three locations except at Mettupalayam. Height and basal diameter could serve as reliable selection index.

Abstract: A 9-year-old Hardwickia binata Roxb. plants at a spacing of 5m x 5 m was intercropped with V. radiata (L.) Wilczek in 2003 to study interactive effects of trees on resource use and crop production. Tree height, collar diameter and crown diameter did not differ (P<0.05) between the treatments. Soil water content (SWC) was heightest (P<0.01) in August and lowest in December, 2003 depending upon rainfall. SWC was highest (P<0.05) in AC plots and reduced in FC/RC plots by 37.1% , 25.9% and 20.2% in August, September and December, 2003, respectively resulted from tree. Lowest SWC in 0-25 cm soil layer and at 1 m from tree suggested competitive use of soil water by the trees reducing crop yield (by 97%). Despite an increase in leaf wate content, reduction in grain was relatively greater than husk and holm. Soil organic matter, PO4-P, NO3-N and NH4-N did not differ among the treatments and distances but these nutrients were highest (P<0.01) in 0-25 soil layers suggesting trees role in nutrient enrichment.

Abstract: Forestry CDM projects involving afforestation and reforestation offer opportunities for CO2 mitigation by removal of accumulated CO2 in atmosphere and sequester it in vegetation, soil and wood products. Besides being grown for longer periods, tree species of medicinal importance are associated with recurring benefits to the growers, on account of fruits, seeds and other products. The potential of involvement of low income communities in growing these tree species for sustainable economic returns make these plantations a promising activity under CDM framework. The present study on plantation of tree species of medicinal importance such as Amla, Arjun, Bael, Bahera, Harar, Jamun, Neem and Reetha has shown that there is significantly large sequestration potential in the range of 3.05 to 11.01 tons of CO2 per ha per year with corresponding carbon benefits of Rs 702/- to Rs 2532/- and Rs 1404/- to Rs 5064/- under carbon prices of dollars 5 and dollars 10 per ton of CO2 respectively on annual basis for a project period of 30 years. The study has further shown that the increase in returns due to carbon benefits can motivate the small farmers to opt for plantation of these species on farm bunds. The eligibility requirements of these plantations as required under the definition of ' Forest ' as acceptable by India is also discussed.

Keywords: Clustering, pollutant tracer hydrochemistry, tariff, Vaal basin, surrogate
Abstract: A mathematical model being used by the Department of Water Affairs (DWA) to analyse various environmental management options emphasises on total dissolved solids (TDS) as a water pollution indicator, to which pollution economic impacts are also related. Since its use, it has become apparent that water quality problems in the Vaal basin are much more complex and need a variety of other management measures. Furthermore, an initial focus on the imbalance between available water, growing demand and increasing river regulation has contributed towards elevated proportions of polluted return-flows to natural runoff. This has led to a decline in quality of water feeding the catchment as well as rising potable water treatment costs. Research being carried out in the Upper (upstream) and Middly (downstream) Vaal Water Management Areas (WMAs) bounded by Vaal dam outlet and Bloemhof dam inlet, aims at developing a multi-year tariff model for surface raw water of variable quality, in order to predict cost of treatment using historical data and compatible toolboxes on a Matlab platform.
Two pre-requisites for developing the model are an analysis of the raw water tariff structure at tier 1 of the cost chain for water services and pollutant tracer hydrochemistry for major pollutants using conductivity (EC) as a surrogate. For 2003-2008 the total cost of raw water for both upstream and downstream utilities was made up of a Water Resource Management charge (WRMC), the Trans-Caledon-Tunnel-Authority (TCTA) charge and an abstraction tariff. Utilities paid the same TCTA charge per year and a slightly varied figure for the abstraction tariff. However, clustering of the WRMC indicated a dominance of the UVWMA for the lower clusters 0.50-1.00 and 1.00-1.50 while the MVWMA predominantly covered the 1.50-2.00 cluster. Results of pollutant tracer hydrochemistry showed a marked deterioration of water quality towards downstream. It was concluded that a downstream utility paid higher WRMC for more polluted raw water than an upstream utility. It was recommended that surface raw water quality variability be incorporated at tier I of the cost chain for water services to ensure fairness of service delivery and spread of burden to consumers based on quality requirements.

Keywords: Neem seed kernels, age, morphology, azadirachtin
Abstract: Azadirachtin is one of the most prominent triterpenoids obtained from neem (Azadirachta indica A Juss) seed kernels. Its demand has been on rise in industries due to its immediate application as an ecofriendly, biodegradable biopesticide and various other significant biological activities. Concerted efforts are being made for its extraction in higher quantities in an economically feasible way. However, fulfillment of this objective has been long overdue owing to high heterogeneity in quality and quantity of azadirachtin present in the seed kernels. In the present study, an attempt has been made to study the effect of various parameters like age and morphometric parameter of seeds, on azadirachtin production in neem trees growing in fifteen different ecotypes. It has been observed that the middle age trees (20-40 years old) produced maximum amount of azadirachtin (4000 ?g/g dry weight of kernels) inspite of that the highest kernel weight was observed in trees of youngest age group.

Keywords: Sulfamethoxazole, photodegradation, iron, oxalate, direct photolysis, kinetics
Abstract: In this work, the direct photolysis and indirect photodegradation of sulfamethoxazole (SMX) in water were investigated under UV-C light (? = 254 nm) and in the presence of Fe(III)-oxalate complex UV-Vis light (? = 365 nm) respectively. The kinetics of both direct photolysis and indirect photodegradation of SMX at the concentrations in the range of 5.0 ~ 20.0 mg L-1followed first-order law and the rate constant of direct photolysis was much higher than that of indirect photodegradation under UV-Vis light. The influential factors of pH values, initial concentration of SMX, Fe (III)/oxalate ratio, as well as the chemicals adding sequence on SMX photodegradation were studied in detail. The Fe(III)-oxalate complex system had strong SMX oxidizing ability at pH 3.5 and the concentration ratio of Fe(III)/ oxalate 10.0/120.0 ?M.
