Abstract: Pinus wallichiana cones collected from two elevations viz., (1500-1700m) and (1700-1900m) and stored for two weeks produced seeds with maximum germinability. At 1500-1700m elevation the seeds showed maximum germination (79%) and germination value (9.97) in case of fresh seeds and 85% and 11.80 in case of stored seeds. However, at 1700-1900 m elevation maximum germination of 81% and germination value of 11.89 in fresh seeds and 85% and 11.62 in case of stored seeds was observed. Hence collection of Pinus wallichiana cones in western Himalayas can ben started during 1st week of October and cones can be stored at room temperature before their dehiscence and seed collection.

Keywords: Water hyacinth,vermicompost, Enrichment, Nutrient content
Abstract: A study was conducted in Tamil Nadu Agricultural University, Coimbatore to explore the possibility of conversion of water hyacinth into nutrient rich vermicompost. The experiment consisted of eight treatments viz., vermicomposting of water hyacinth using earthworm E. eugeniae, P excavatus, Perionyx + Eudrilus mixed culture and a treatment without introduction of earthworm (control). All the above four treatments were tried with and without enrichment by Azospirillum, Phosphobacteria and rock phosphate. The results revealed that water hyacinth is a suitable material for vermicomposting. Among various treatments, vermicomposting with E. eugeniae along with enrichment is superior, considering the total N, P, K, Ca and Mg content of the vermicompost. Enrichment with Azospirillum, phosphobacteria and rock phosphate significantly increased the total N, P and Ca content in the vermicompost.

Abstract: In Atomic and thermal power plants the temperature difference (?T) between intake and outfall assumes greater importance for laying down legal limits for thermal discharges. In order to ascertain the adverse impact of elevated temperature on the life of aquatic animal such as wedge clam Donax cuneatus (L.), experiments were conducted at different (?T) temperature and their thermal tolerance was assessed from percentage of mortality. The thermal tolerance experiments were conducted in the field as well as in the laboratory. In the field, the cage experiments were carried out in the thermal discharge canal located on the coastal site where Madras Atomic Power Station (MAPS) discharge the thermal effluent. In the laboratory, the experiments were conducted in two modes: (1) Gradually increasing temperature and 2)Direct exposure. In the upper Incipient Lethal Temperature experiment 100% mortality of Donax cuneatus was found in 75 minutes at 480C and in the lower Incipient Lethal Temperature experiment no mortality was found at 200C for 48 hours. Percentage of mortality due to direct exposure in different ?T(?T 50C (330C), ?T 70C (350C), ?T 100 (380C) and ?T 120C (400C) at 48 hours was observed that there was no mortality at ?T 50C and ?T 70C. However, 50% mortality was recorded at ?T 100C and 70% in T 120C. Field experiment on thermal tolerance of Donax cuneatus at the discharge canal indicated that elevated temperature (above 350C) of the heated effluent could not affect the orgnism.

Abstract: In an oil field oil from the wells is pumped to Group Gathering Stations (GGS) where the oil undergoes some treatment and is stored for transporting to refineries. A large number of contaminants including heavy metals enter into the nearby agricultural fields of a GGS through spills, leaks as well as through emissions from gas flaring and from effluents which are likely to pollute the environment. Plants can take up heavy metals from air and water as well as from soil and sediment. Excess concentrations of heavy metals in plants are toxic to both plants and animals. We investigated heavy metal accumulation in plants at crude oil contaminated sites near the five well-known GGSs, i.e., Rudrasagar GGS1, Rudrasagar GGS2, Lakowa GGS1, Lakowa GGS3 and Lakowa GGS9 operated by the Oil and Natural Gas Corporation Limited in Assam. Rice grains, papaya fruits and tea leaves in crude oil contaminated areas and uncontaminated areas were sampled. The concentrations of seven heavy metals (Cd, Cu, Zn, Fe, Mn, Ni and V) in rice grains, rice husks, papaya fruits, and tea leaves for different locations were determined. Soil samples were also taken (at 0-45 cm depth) for the measurement of total petroleum hydrocarbon content. Variation in heavy metal accumulation in a plant part depending upon the growth sites was studied. Results indicated that the concentrations of heavy metals in the plants increased with the increase in crude oil contamination of the growth sites. Substantial differences in the abilities of various plant species to accumulate the heavy metals were also observed. In the plant samples, the element wise variations in metal concentrations were found to be very complicated. Our results indicate that the consumption of rice grown in contaminated soils may pose a serious risk to human health.

Abstract: Present investigation work Activity levels of Aspartate Transaminase (AAT) and Alanine Transaminase (ALAT) in freshwater fish Labeo rohita exposed to Deltamethrin. Aspartate and Alanine transaminases (AAT and ALAT) are widely distributed in the cells of all animals and serve to link the carbohydrate and protein metabolism, by interconverting dynamic substances. These two enzyme activity levels were estimated in lethal 1, 4 days and sublethal 1, 4 and 8 days concentrations in different tissues. In lethal concentrations activity was more than that of sublethal concentrations. Whereas in sublethal concentration the increase of these parameters in the tissues of fish was more at day 4 and less at day 8 which was in the order 1< 4> 8 day. The activity levels were in order to gills > muscles > liver.

Abstract: Red tides caused by Euglenoid protozoans are common in the floodplain wetlands of Barak Valley, Assam, North-East India. Though the presence of Euglena renders water unfit for drinking, its role as food for surface feeding fishes makes it important to fish farmers who artificially induce euglenoid bloom for augmenting fish production. A study on the fluctuations of the chemical parameters, major phytoplankton taxa and chlorophyll concentration of phytoplankton from morning to afternoon in five ponds revealed that no specific pattern could be discerned in the concentration of chemical parameters except Mg, chlorophyll a and free CO2. Concentration of Mg and free CO2 were lowest in the afternoon in all the five ponds and chlorophyll a was found to be highets in the morning in all the ponds except pond 1. DO showed significant positive correlation with chlorophyll b, NO3 and TA. Mg was found to be significantly positively correlated with TA, conductivity, TDS, Zn, chlorophyll a and free CO2. No significant relationship of phytoplankton taxa with chemical parameters was recorded. Euglenophyceae showed significant positive relationship withChlorophyceae and significant negative relationship with Bacillariophyceae.

Abstract: In order to study the effect of planting date on potato growth indices, a field experiment was conducted in Mashhed area in 2008. The experiment was laid out in a split plot design with three replications. Planting date (9 and 30 may, 20 June and 11 July) was the main plot, and varieties in subplot. Results concluded that the leaf area index in primary planting, because of more different growth condition, got to the maximum level at a later time and Agria variety in the third planting date (June 20) had the highest leaf area index between other varieties. Total above dry matter in primary plant dates in comparison to other planting was higher. Crop growth rate in comparison to other growth indices had a closer connection with the crop yield. So Almera having the most tubers yield, presented the maximum production rate. The point to consider is that with delay in planting date and length reduction of variety growth, all growth indices got to their maximum value. According to the results obtained from the experiments, maximum tuber yield was yielded from second and third planting of the Almera result conduced form this test, maximum tuber yield was yielded from second and third planting of the Almera variety.

Abstract: Drought stress is one of the most important abiotic stress which suffer damages on tobacco production in many countries including Iran. Thus, investigating of drought tolerance genotypes is the important goal in tobacco breeding projects in Iran. For the reason, five Virginian tobacco genotypes and their hybrids were evaluated in a RCBD with three replications in two different environments (water stress and normal irrigation). In the present investigation, some tolerance indices were studies in five Virginia tobacco together and their hybrids (fifteen genotypes). The materials were evaluated in two different experiments using a RCBD with three replications in two environments (water stress and normal irrigation). In the present investigation, some tolerance indices were studies in five Virginia tobacco together and their hybrids (fifteen genotypes). The materials were evaluated in two different experiments using a RCBD with three replications in two environments (water stress and normal irrigation) in the Tirtash and Rasht tobacco research station during 2006 and 2007. Based on the dry leaf yield potential (Yp) and yield stability (Ys), some quantitative criteria of drought resistance such as : mean productivity (MP), tolerance index (TOL), geometric mean productivity (GMP), harmonic mean (Harm), Stress susceptaibility index (SSI) were figured out. Significant differences were observed among genotypes for all indices and for potential and stress yields, indicating the existence of genetic variation and possibility of selection for drought resistance. Correlation analysis among indices, potential and stress dry leaf yield indicated that were MP, GMP and STI the most suitable criteria for screening tobacco genotypes. Multivariate biplot indicated that k394 x NC89, NC55 and NC89 x Coker347 in Tirtash and CC27 and Coker254 x VE1 in Rasht have highest yield and they have tolerance to drought stress. Distribution of the genotypes in the biplot space indicated the presence of genetic diversity among the genotypes for drought stress.

Keywords: Heavy metal, brain, Gobius malabaricus
Abstract: Periyar, one of the major rivers of Kerala state passes through the highly polluted industrial area, Eloor and Chitrapuzha region. Heavy metal pollution is one of the major problems of the water pollution in this region. Heavy metals are vigorous oxidizing agents and thus are highly bound to biochemical inability of tissues and thus affect fishes.
The main objective of the study was to check whether the heavy metals have targeted the most vitally protected tissue-the brain and to analyse the increasing tendency of heavy metal accumulation with age in fishes. The study area includes the higly polluted Eloor and chitraphuzha area, nearly 11 kms away from Kochi.
The Fish, Gobius malabaricus, belonging to the family Gobidae were collected, weighed and grouped. Fishes were dissected for brain tissue, weighed, homogenized and heavy metals were detected using ICPAES (Inductively coupled plasma atomic emission spectrophotometer). The study showed heavy metal accumulation in the order Copper > Manganese > Zinc (0.55 ppm). Cadmium and Chromium were found below detection limit. The greatest accumulation of heavy metals was found in the brain of older fishes. Accumulation of heavy metals even in the brain of fishes, thus, indicates the extent of heavy metal pollution in the industrial area.
