Abstract: India has a long coastal line of over 7500 km supporting vast habitats such as lagoons, backwaters, estuaries, coral reefs and mangrove ecosystem commands the higest importance because of its biological productivity and specialized diversity. After coral reefs, mangrove forests have the highest productivity among the coastal wetlands. With regard to biodiversity, mangroves support a unique group of fungi, microbes, plants and higher animal species including several species of migratory water birds. Such unique wetlands are in peril due to increasing salinity in recent times especially after the tsunami of 2004. It is time to control the increasing salinity, failing which the Indian subcontinent stands to lose its unique coastal biodiversity which, in turn, might affect the marine food web of hte entire tropical region.

Keywords: Neem, Azadirachta indica, A. Juss, Reproductive studies, Spermidine application
Abstract: The in vivo morpho-physiological responses to spermidine application in Neem (A. indica) were studied during three consecutive annual reproductive flushes from bud development onwards to seed set (prior standardization with endogenous levels). The number of buds and flowers per inflorescence was higher in treated branches as compared to the control. Physiological responses were observed to be polyamine -specific. Year 1 sample protein, total sugar and reducing sugar measured higher following spermidine at 0.2 mM as compared to spermidine at 0.5 mM. The response to year 2 treatments was even better, being significant in 0.2 mM spermidine samples. Year 3 spemidine treatments produced poor flowering response, longer juvenility and low contents of the above compounds as compared to the control. The enzyme assay measuring the activities of invertase, protease, acid- and alkaline phosphatases was consistent with the biochemical responses to teh spermidine treatments. In control, a shorter regeneration phase seems to lead to lower productivity in terms of floral inflorescence and fruit set. Therefore, it is suggested that the application of spermidine may regulate the reproductive phase resulting in improved organ/biomolecule production.

Abstract: The present investigation deals with effect of structural composition of agroforestry system, number of woody perennial involved in the system and the management practices plays a major role in influencing the biomass level, carbon storage, CO2 mitigation potential and total carbon sequestration (in trees) of 70.59 tha-1, 21.38 tha-1, 116.29 tha-1 and 18.53 t C ha-1in system S1 followed by 68.53 tha-1, 20.63 tha-1, 113.03 tha-1 and 17.60 t C ha-1 in system S4 , respectively. It was also observed that all the agroforestry systems can sequester more carbon as compared to sole agricutural land use systems. It was also observed that Populus deltoides + wheat and Populus deltoides + lemon grass under block plantation have the maximum potential to sequester carbon than the boundary plantations of Populus deltoides and Eucalyptus hybrid.

Keywords: Growth and flowering, Growth cycles, Liparis cordifolia
Abstract: Liparis cordifolia is a cool growing terrestrial orchid distributed in Himalayan region. Small sized-plant, and its heart-shaped shining solitary leaf, long lasting elongating raceme and low light requirement during cultivation make it an attractive plant for indoor decoration. The growth and flowering behaviour of this species under Darjeeling conditions are reported. The shoot bud arised in July and August from basal part of the pseudobulb and inflorescene emerged from the top of recently formed stem (pseudobulb) 23.8 days after initiation of shoot bud. The first flower bud opened in the last week of September to October, 15.12 days after emergence of flower buds. The raceme remained in flower for 54.18 days up to first week of December. The growth phase marked by emergence of roots from the basal part of stem and swelling of pseudobulb in last week of November to first week of December. This phase lasted for 183.81 days. The plants proceeded to dormancy after senescene and drying of leaf in April and May. The data on morphological characters like pseudobulb length and width, leaf length and width, inflorescene length, racemose length, number of flowers are tabulated. Inflorescence length, raceme length and number of flowers were found to determine by length and width of previous years growth (pseudobulb) The various plant parts when compared with colour chart developed by Royal Horticulture Society showed different shades of green yellow colour. The leaves were found to have deepest (RHS 146 A, 146 B, and 147 A) and sepals and petals lightest green yellow color (RHS 145C and 145 D).

Abstract: Bhimbetka World Heritage Site in Madhya Pradesh is quite important both from archaeological and biodiversity point of view. There are over 700 rock shelters with world ' s oldest Stone Age rock paintings, which are surrounded by a thick cover of primeval forests supporting a rich biodiversity. The forests of the area are typically dry mixed deciduous type with preponderance of Mitragyna parviflora, Terminalia alata, Careya arborea, Chloroxylon swietenia, Sterculia urens, Ficus mollis, Lannea coromandelica, Anogeissus latifolia, Schleichera oleosa and Diospyros melanoxylon trees. An analysis of floristic diversity revealed that there are 201 species of flowering plants belonging to 157 genera and 56 families. The legumes are most dominent in the area in respect to number of species (36 spp), followed by families like Malvaceae (13 sp) and Euphorbiaceae (12 sp). An assessment of economic potential of the flora has also been made based on the first hand information generated from local inhabitants mainly Gond adivasis. The economically potential species are categorised into different groups based on their uses. Rare and endangered species have also been identified based on the status evaluation of their populations.

Abstract: Prosopis cineraria was grown in a green house in a low phosphorus (4mg kg-1Olsen ' s P) soil (Typic Camborthid) under arid environment inoculated with alone or mixed AM fungi either indigenous or from outside sources. Uptake of relatively immobile soil nutrients (P, Zn, Cu) as affected by different AM fungi was also studied. In general, significant and positive response of plant height, root and shoot biomass, root colonization and AM fungal population was observed in inoculated plants as compared to control. Inoculated plants had significantly higher P, Zn and Cu concentration as well as upto three times more total uptake. Mycorrhizal dependency to P. cineraria varied between 13.76 and 56.28%, which was more to Glomus aggregatum. In general, G. aggregatum was found to be the most efficient AM species for growth and nutrition of P. cineraria plant.

Keywords: Genetic variation, Eucalyptus tereticornis, Half-sib progenies, Punjab Agricultural University, Ludhiana
Abstract: Being suitable species for timber production, genetic improvement programme of Eucalyptus tereticornis was started in Punjab Agricultural University, Ludhiana by selecting superior phenotypes and raising their progeny trial. In this study, phenotypic and genetic variation of 18 months old half-sib progenies of 17 selected plus trees were assessed for the height (m) and collar diameter (cm). The maximum mean height and mean collar diameter were 2.50 m and 2.20 cm respectively in family no 16. The individual tree heritability for height and collar diameter was estimated 0.30 and 0.24 respectively, while the family heritability was 0.65 for height and 0.60 for collar diameter. The phenotypic and genetic (additive) variance among the families for the height was 0.38 and 0.11 respectively, while it was 0.64 and 0.15 for collar diameter. The phenotypic coefficient of variability was 29.10 % for height and 46.75% for collar diameter while the gentic (additive) coefficient of variability was 15.86% and 22.72% for height and collar diameter respectively. The estimated genetic gain was 0.49m and 0.50 cm for height and collar diameter respectively.
