Abstract: Above-ground biomass of pioneer species of the Mangrove Swamp succession along the Lagos Lagoon coastline was investigated. Of the two most abundant species, Paspalum vaginatum had the largest biomass (3.8 + 1.2 kg m -2), twice as high as that in Cyperus articulatus in pure stands. Furthermore, its biomass accrual was about four times as that of C. articulatus when both occurred together. There was no significant difference in the biomass when each pioneer species occurred with other species. The mean weekly biomass accrual was highest also in P. vaginatum (1.92+ 0.62 kg m-2 wk-1) during the period of investigation. It was estimated that P. vaginatum contributed about 47% to the total biomass of the Mangrove Swamp whilst C. articulatus contributed about 20%. Biomass accrual was significantly correlated with soil moisture.

Abstract: Today in India and the entire world, electrical energy utilization in space ventilation dominate the field of commercial and House hold utilities. HVAC system consumes more electrical energy, and it is believed that electrical energy will be costly and scare in the near future. Therefore alternative energy sources use will become mandatory and even more common in the coming decades. Here, Energy reforms is the need of the hour. Subsequently, solar energy is a completely natural, renewable energy applicable in all most where electrical energy is used. Furthermore, solar energy utilization is actually reducing major greenhouse gases in the atmosphere. Hence, it is a boon in mitigating global warming and creates carbon free economy. This study is concerned with the design of a solar chimney to induce ventilation in a building by using CFD model. In this study CFD (GAMBIT and FLUENT) techniques were utilized to assess the impact of inclination angle and gap between glass cover and insulated absorber. It was found that, for a south-facing chimney, an inclination angle of 500 from the horizontal was optimum for the location of Tiruchirappalli (Longitude + 78.69 E, latitude + 10.81) giving greater efficiency than the vertical chimney by using a Black coated aluminium wall surface. In both summer and wintger seasons with vertical chimney the height of inclined chimney is having 25% less structure height and there is no variation in efficiency between them.

Abstract: Sacred groves are one of the finest examples of traditional in situ conservation practices and act as treasure house of endemic, endangered and rare plants. Endemic species of any geographical region, throw light on the biogeography of the area, areas of extinction and evolution of the flora. Six famous sacred groves of Kannur district were selected for study. Studies were aimed at the documentation of floristic diversity with special reference to endemic plants and to know threats to them. The vascular flora of the studied groves comprises 341 species belonging to 265 genera distributed among 99 families, with 329 angiosperms, 11 Pteridophytes and Gnetum ula Brongn. Major attration are the presence of 48 endemic (14.1%), 80 edible (23.5%), 269 medicinal (78.9%) and 7 critically endangered plants. Only 10 plants are common to all the groves while among endemic plants only three show common presence, making them an important gene pool. The percentage of endemic plants ranges from a minimum of 11 in Andallur to a maximum of 18.1 in Edayilakkad.

Keywords: Multivariate analysis, Genetic distance, clusters, hybridization and anthurium
Abstract: Sixteen anthurium genotypes were assessed for the nature and magnitude of genetic divergence among them based on 14 agro-morphological traits following Mahalanobis D2-statistic. On the basis of D2 values, the sixteen genotypes were grouped in to six clusters following Tocher ' s method. The magnitude of D2 values indicated that there is a considerable diversity in the materials studied. The D2 cluster means and inter cluster coverage divergence were utilized for the choice of parents to decide the cross combination to produce heterotic effect. The most divergent clusters were IV and V (D2 = 97.12) followed by I and V (D2 = 84.31) and clusters V and VI (D2 = 80.51). Highest intra-clustrer distance was observed in cluster IV followed by cluster I. Cluster I was largest one containing 7 genotypes from different characters. The clustering patterns of the genotypes were quite at random indicating that the geographical origin and genetic diversity were not related. The characters contributing more towards the genetic divergence were days of interval between two flowers, spadix length, spadix diameter, days taken for stigma receptively and percent disease incidence.

Keywords: Plant growth retardants, African marigold
Abstract: The present investigation was carried out to study the effect of Plant Growth Retardants on flower quality and yield of African marigold. Three plant growth retardants i.e. maleic hydrazide, cycocel and SADH (Alar) with three varying concentrations have been used and were evaluated against the two control treatments *(control without pinching and control with pinching). All three plant growth retardants were signifiantly superior over the two control treatments in all aspects of flower yield and quality. SADH 2000 ppm treatment recorded significant delayed initiation of first flower bud (47.13 days), duration for opening of flower from flower bud emergence (24.00 days), duration of 50% flowering (81.57 days), increase in number of flowers per plant (36.57), yield of flowers per plant (232.21 g), per hectare (12.90 t) and highest vase life of flowers (7.0 days). SADH 1500 ppm recorded significantly maximum flower diameter (5.43 cm) and weight of 20 flowers (138 g), while SADH 1000 ppm gave significantly highest seed yield per flower (255 seeds). Cycocel 750 ppm recorded the signficantly maximum flower stalk length (15.50 cm). Significantly highest 1000 seed weight was recorded in maleic hydrazide 500 ppm treatment.

Abstract: Societies have always depended on the climate. When climate is changed it will affect the human beings directly. The climate change is caused by too much emission of green house gases. The main green house gas is CO2. This is emitted more from the combustion of fossil fuel. The concentration of CO2 was 280 ppm in 1760 but it increased to 379 ppm in 2000. As a result, global warming has been realized all over the world. The heat waves and strokes are killing many people especially children and old age people. The World Health Organization (WHO) estimated that 34% of all childhood illness in the world and 36% of death in children under the age of 14 are due to modifiable environmental factors. The vector borne diseases like malaria, diarrhea and dengue are spreading all over the world. If global warming continues, it will create more threat to human beings. As a result, heavy economic and human loss will be happened throughout the world. The need for the hour is to mitigate the emission and protect the health of the people in the gifted planet.

Abstract: In Tamilnadu, one of the important States in India, a large number of tannery industries operate and release huge volume of the tannery effluent and sludge that contaminate the nearby agricultural lands as well as the underground water. Besides, there is always a pungent and foul smell in and around the industry installations. From the perusal of literature, it is evident that an in-depth study is totally lacking with regard to reclamation of the tannery polluted soil for raising fast growing tree species either for fire wood or timber. Therefore, in the present study using pot culture method , the effect of tannery sludge on the growth of fast growing tree species was investigated as a prelude to employ right type of tree species in reclamation of tannery polluted soil. The plants raised in pots containing the garden soil served as the control. The morphometric parameters of the 12 months old tree saplings showed enormous proliferation of aboveground biomass and the overall growth was not affected at all.
