Abstract: Assessment of water quality is important as water is used for domestic, agricultural and also industrial purposes. The coastal stretch of Andhra Pradesh abutting Bay of Bengal is also a part of the Coromandal coast that runs to a length of 960 km on the east coast of India. The two large rivers Godavari and Krishna, which originate in the west coast, join the sea with in a gap of 200 km between them. The rivers, in addition to suspended sediments coming through surface runoff, also receive discharge of domestic as well as treated adn untreated industrial effluents. The water samples of various freshwater bodies from 80 different statiosn in the nine districts were collected and analysed for their physicochemical characteristics to determine the hydrogeochemical characteristics of the stretch of Andhra Pradesh.

Abstract: Emission from coal fired thermal power stations discharges numerous types of gases as pollutant in the ambient air environment, which is causing potential threats to crop production. This study deals with the effects of sulphur dioxide on rice crop (Oryza sativa L.), and yield responses at selected rural sites adjacent to the power station. Eight hour averaged SO2 concentrations were measured at the two statiosn during the crop period. Physicochemical parameters of the soil and water samples were observed in the crop fields in pre-flowering, flowering as well as post-flowering phases. The uncontrolled area was located by determining the predominant wind direction with the help of wind rose using the meteorological frequency data whereas the controlled area was located upwind to predominant wind direction. The data were constructed and related with the yield responses. There was only a slight reduction in yield of rice crop because of the thermal power plants.

Abstract: Biomonitoring is a method of observing the impact of external factors on organisms and their development over a long period. The level of Zn, Cu, Cd and Pb has been determined in samples of the moss Bryum cellulare from the area of Almora, Nainital and Pithoragarh of Kumaon hills. A gradient was observed in metal load while projecting from forests to urban areas. Maximum metals were observed in locations proximate to higher traffic density areas, which integrated due to enhanced tourism during summer, followed by winter and monsoon season. In rural areas high value of Zn, Cu and Cd attributes to their use in fertilizers. Positive significant correlations were obtained between Pb-Zn and Zn-Cu suggesting a common origin of these metals. Interseasonal variability in metal deposition pattern shows that summer had maximum metal load followed by winter and rainy season.

Abstract: Verticillium dahliae was identified as a pathogen causing wilt disease of Polyalthia longifolia. It was isolated from the infected roots of the seedlings collected from Central Forest Nursery of Imphal, Manipur, India. Four fungicides viz. Bavistin 50% WP, Dithane M-45, Dithane Z-78 and Fytolan 50% WP were screened against the pathogen at different concentrations using poison food technique in vitro and then in field - conditions using soil drenching technique. The results revealed that Bavistin 50% WP was most effective at 75 ppm with 100% growth inhibition followed by Dithane M-45, Dithane Z-78 and minimum efficacy was observed by Fytolan 50% WP with 31.27% growth inhibition in laboratory conditions. All selected fungicides were evaluated against pathogenin field conditions at 0.1% and 0.2% concentrations. Bavistin 50% WP was found to be the most effective at 0.2% concentration. Thus the present study recommends soil drenching with Bavistin 50% WP at a minimal concentration of 0.2% for management of the disease.

Abstract: Forest Fire, an anti enviornmental human activity, is becoming a great threat for eco restoration of Cherrapunjee- the site famous as wettest place on earth. Human ' s carelessness, negligence and ignorance are the main causes of annual ground fire resulting into pronounced and prolonged ill effect on climate, land use, land cover, biodiversity and forest ecosystem. There is an urgent need of fire management practices based on scientific technology, where emphasis should be given on people ' s participation through Joint Forest Management Programme.

Abstract: Healing of boreholes involved sequential production of callus tissue and formation of vascular cambium by dedifferentiation and conversion of callus cells into cambium cells. Healing of boreholes was initiated by callus formation from edges. The callus growth on lateral sides of the hole has been observed to be more than top and bottom of the borehole resulting into formation of narrow elliptical shaped hole after healing upto two years. The healing percentage showed decreasing trend with increase in the diameter of boreholes. The boreholes of 0.50" (1.25 cm) diameter showed maximum healing percentage of 28.46 percent and minimum healing percentage of 2.86 percent was obtained in 1.25" (3.125 cm) diameter boreholes after one year of tapping. Whereas, the healing percentage in 0.50", 0.75" and 1" diameter boreholes was observed to be 70.73, 59.42 and 53.56 percent, respectively after two years of tapping.

Abstract: Laboratory study was conducted on one year seeds of Fraxinus floribunda during August 2006. In order to over come poor and slow germination due to dormancy, the seeds were first moistened for 48 hours imbibition and thereafter subjected to (warm, cold and warm + cold) stratifications ranging from 1 to 4 week duration. Seeds thereafter were put to germination test in petri plates on germination paper at 20 + 20C in seed germinator. Germination was recorded after 7 days and continued till 30th day. Results obtained indicated that F. floribunda has intermediate physiological dormancy and the same can be over come by cold stratification for a period of 4 weeks. Germination percent, mean germination time and germination value were 78%, 16.42 days and 26.67 respectively after 4 week of cold stratification.
