OKWUOKEI, Tobechukwu Louis
This research assessed the diversity in species of woody species within the lowland rainforest floristics of Ika region, Nigeria. The research design used was the quasi experimental approach. The Ika region was stratified into 12 sub-areas, while selection of sampling units was made using the technique of random sampling. The sampling units were specified into two different groups as secondary (degraded areas) and primary (mature rainforest within conserved areas) groves. From each sub-area, 2 sampling units were selected randomly, making 24 sampling units. Data collection which was based on species of the woody trees and their populations together with the sampling areas, adopted the quadrat size of 10m x 10m to ensure effectiveness. Standard approaches were followed in data collection; while data generated were analysed using graph, Simpson’s index, and student t-test statistics. Population of the tree species varied in the 2 ecosystems. Tree species such as Milicia excelsa, Swietenia macrophylla, Alstonia boonei, and Aniba rosaeodora are gradually becoming threatened. Tree species diversity varied between the 2 ecosystems, with observed loss of biodiversity. Tree species were more diverse in the primary grove. Simpson’s indices of tree species diversity values for the secondary and primary groves are 0.5783 and 0.8050. With probability, variance and t-values of 0.000, 0.0015 and -14.027 respectively, species diversity between the 2 ecosystems is significant at 0.05 level of confidence. Degradation has negatively impacted on the rainforest and its tree species. Reforestation of the degraded rainforest is recommended for sustainability.

Plant growth–promoting rhizobacteria (PGPR) inhabits the plant roots and has positive effects on plant growth and physiology. To investigate the effect of inoculation of plant growth promoting rhizobacteria in Radish plants, four bacterial strains i.e. Pseudomonas putida, Pseudomonas fluorescens, Azospirillumlipoferum and Bacillus subtiliswere applied to radish plants at 3 leaf stage along with some plants left untreated to act as control. Experimental analysis of different parameters revealed that morphological parameters viz. plant height, number of leaves, fresh weight and dry weight were found to be improved in response to the applied PGPRs in comparison to control plants. Various biochemical parameters like nitrate reductase activity, superoxide dismutase activity and protein content were also found to be improved in response to PGPR application. Therefore, from the results obtained it can be concluded that use of PGPR has immense potential to be used as agricultural crop inoculants as they promote plant growth as well as improve the health and yield of the plants.

Grain legumes, which are interchangeably called pulses in the Indian sub-continent, have occupied an important place in the daily diets of the population of the region due to their nutritional potential, particularly as rich sources of proteins. In the present study, physicochemical attributes and the impact of UV-B irradiation on the black gram (Vigna mungo (L.) Hepper) were documented. The hundred seed weight of the black gram is higher than certain common legumes cultivated in India. The seeds posse good physicochemical properties which can be incorporated into human diets not only as protein supplements but also in processed food such as weaning, backed and soup products. In this paper, we investigated the changes in morphological, photosynthetic and physiological responses of the black gram seedlings to UV-B radiation. In the present study, the results showed that the growth of black gram was adversely affected under UV-B exposure with the response depending on the duration of exposure. Maximum reduction of growth i.e., plant height, internodal length, leaf area, plant fresh weight, plant dry weight, plant water content, chlorophyll a, b and total chlorophyll, was noted under the higher duration of UV-B irradiation.
