Abstract: Laboratory experiments were conducted to estimate crystalline protein (CrylAc) levels in two Bt cotton hybrids TCH-4 and TCH-117 for two consecutive seasons during 2006-07 and 2007-08. The CrylAc protein content was high in leaves from top canopy (6.5 & 6.1 ?g/ g) followed by leaves from middle (6.1 and 5.7 ?g/ g) and bottom canopies (5.8 and 5.3 ?g/ g), square bract (1.9 & 1.7 ?g/ g), square bud (1.3 & 1.2 ?g/ g), seed (1.4 & 1.2 ?g/ g) and greenboll (0.8 & 0.7 ?g/ g) while caly x (0.7 & 0.5 ?g/ g), corolla (0.4 & 0.3 ?g/ g), anthers (0.2 & 0.2 ?g/ g), stigma (0.2 & 0.2 ?g/ g) had the lowest expression in TCH-117Bt and TCH-4Bt hybrids, respectively at 60 DAS. The order of CrylAc insecticidal protein content in different plant parts were leaves > squares>bolls> flowers. The CrylAc protein content in al the plant parts decreased by 90 days after sowing (DAS) compared to 60 DAS, further decreased at 120 DAS and reached to negligible levels by 150 DAS.

Keywords: Phosphorus sources, solubilisers, Cropping system, Vertisol
Abstract: A field experiment was conducted during 2000 to study the response of sunflower - maize cropping system by the application of selected phosphatic fertilizers, namely, single superphosphate (SSP), Mussorrie rock phosphate (MRP), paritally acidulated rock phosphate (PARP) and mixture of these on equivalent P2 O5 basis with P solubilisers (FYM, PSM & pyrite). Direct effect of phosphorus sources and solubilisers on sunflower and residual effect on maize was studied. It was found that yield of sunflower did not differ due to application of P sources and solubilisers. The highest (27.1 q /ha) and the lowest (24.4 q/ha) yield of maize were registered with residual effect of SSP and P control, respectively. Available P at harvest of both the crops was high with SSP treatment. At harvest of maize, MRP treatment recorded 9.0 percent higher available P than P control (no P source. Available P due to solubilisers was in the order of FYM>Pyrite>PSM>Control. Application of phosphatic fertiliers along with phosphorus solubilisers did not influence on phosphorus uptake and yield of sunflower. But residual effect of SSP along with FYM recorded the highest yield of maize.

Keywords: Rattans, Germplasm, Canetum, Conservation
Abstract: Canes, commercially known as rattans, are represented by four species of Genus Calamus in Orissa and they include Calamus rotang, C.viminalis, C.guruba and C.latifolius. Canes are of immense value for the tribals, local people and teh artisans for their livelihoods. Khurda forest division has a good distribution of Calamus in the semi-evergreen and moist deciduous forest types. Unscientific exploitation coupled with poor regeneration of canes, lead to destruction of valuable cane species in semi-evergreen and moist deciduous forest types. Rigorous plantation programmes in tandem with effective conservation strategies would ensure the rejuvenation and recovery of the cane species. It is also imperative to conserve the genetic resources of canes not only for revival of teh species both in-situ and ex-situ, but also for sustenance of livelihood of the local artisans and the tribal people who depend on these resources.

Abstract: Silkworm Bombyx mori races were reared in the laboratory and protein content of silk gland in the fifth instar was estimated in NB4D2, Nistari x P5 and PM x P5 races. NB4D2 showed a better performance among the selected races. Increased concentration of salivary gland proteins in NB4D2 (0.8g-04.3g) may be due to feeding of more coarse mulberry leaves and their assimilation and subsequent appearance of many stage specific proteins during fifith larval period.

Abstract: ADP-glucose pyrophophorylase (AGPase) activity in the developing grains of four wheat (Triticum aestivum L.) cultivars DL 153-2, C306, HD 2329 and WH542 grown under normal (27 November) and late (28 December) sown conditions was determined in relation to their grain growth and starch content. In order to analyse the temperature sensitivity of AGPase, excised developing grains (20 days after anthesis) of normal sowing were exposed for 1h at 25oC, 35oC and 45oC and subsequently analysed for AGPase activity. AGPase activity in the developing grains was also determined in presence of PGA and Pi to evaluate the sensitivity of the enzyme to allosteric effectors. The study showed a highly significant correlation of AGPase activity with starch accumulation and grain growth in wheat under normal sowing but not so under late sowing. However, AGPase was not found to be that sensitive to moderate heat so as to be responsible for decreased starch accumulation and grain growth under late sowing. PGA helped in overcoming inhibition by Pi but did not activate the AGPase further. However, genotypic differences in the sensitivity of AGPase to allosteric effectors were observed. An efficient AGPase insensitive to regulation by PGA and Pi in wheat grain would lead to faster starch accumulation and early filling of grains and may thus avoid extreme terminal high temperature experienced during grain development.

Abstract: The comparative assessment of morphologic runoff and annual silt load from micro-watersheds can help in establishing relationships between these parameters with objectives of controlling runoff, conservation of soil, reduction of reservoir silt load and enhanced groundwater resources in the micro-watersheds. The automated watershed delineation technique using the filled digital elevation model is observed to be reliable for area having converging slopes The estimation of watershed based annual silt load using universal soil loss equation along with runoff estimation utilizing the soil conservation services model using remote sensing data is possible on such automatically delineated micro-watershed groups.This can be validated through ground measurements. The output in raster geographic information system (GIS) is highly beneficial in making an inventory of soil loss, runoff and morphologic parameters with an objective of establishing relationship between these parameters for planning conservation measures. The GIS output products like soil-erosion potential map, run-off potential map, etc. obtained by using raster interpolation techniques are of value addition for developing and harnessing natural resources enabling sustainable development.

Abstract: The bulk of the late Arcaean volacanic- volcaniclastic rocks from the Gawler Craton range in age from c.2535 to 2510 Ma (Fanning, Reid and Teale 2007). However, these units were preceded by an older set of volcanics, the c.2558 calcalkaline volcanics of the northeastern Gawler Craton (Cowley and Fanning 1991). These older bimodal volcanics have not been discovered in outcrop and are confirmed only in one mineral exploration drillhole, DP1, located in the northern Olympic Cu-Au province, midway between Olympic Dam and Prominent Hill. Upon discovery, these low-grade metavolcanics were initially correlated with the c. 1592 Ma Gawler Range Volcanics (Giles 1981). However, U-Pb zircon dating defined an eruption age of 2558 + 6 Ma (Cowley and Fanning 1991) indicating the volcanics were a significantly older and unrelated magmatic event. These older volcanics, informally known as the Devil ' s Playground Volcanics, are formally defined herein. The calcalkaline geochemistry and low-metamorphic grade make these volcanics an exploration target in themselves, with potential for volcanic-related sulfide and /or gold mineralisation. Recent PACE-supported drilling by Eromanga Uranium Limited in the vicinity of DP1 intersected weakly metamorphosed basaltic to andesitic volcanics at depths < 300m. This article presents petrological and geochemical results from these recently discovered volcanics along with a discussion of possible correlations. The data has implications for our knowledge fo the distribution, geochemistry and mineral potential of the c.2558 Ma volcanism within the Gawler Craton.

Abstract: Based on established linkages between ferrimagnetism and heavy metal concentration of anthropogenic particulates, we attempt here to delineate pollutant residing domains and study the role of surface runoff and wind circulations over its redistribution in the Pune Metropolitan Region (PMR) in Maharashtra. A total of 118 samples collected in a ~3 X 3 km grid during pre- and post-monsoon seasons for surface soils, bed-rock, dust and rainwaters were analysed for magnetic susceptibility (Xlf ) and the isothermal remanent magnetization (IRM). The Xlf in the soil profiles decrease from bedrock to intermediate soil horizons but notably increase towards top. Spatial variations based on the fundamental rock magnetic parameters (Xlf and their frequency dependency (Xfd), saturation IRM, demagnetization ratio) and knowledge of the polluting sources show significant anthropogenic loading for the topsoils. The study further reports remarkable post-monsoon changes in all the parameters controlled by surface run-off due to slope variation which appears to be the most effective mechanism of redistribution and dumping the topsoils loaded with anthropogenic particulate matters. Distribution of Xfd% further wind as another important agent for dispersal of finer ferrimagnetic particulate matters predominantly controlled by the topography amongst other meterologicla factors. Additional data for succeeding years would help in modelling the redistribution sensitivity and heavy metal residence effect for topsoils and sediments in the PMR region.
