Kuntze) from leaf calli Sivapriyadharshini, A; Ranaweera, K.K; Ranatunga, M.A.B; Seran, T.H Somatic embryogenesis is an efficient regeneration system with high genetic integrity which useful in the crop improvement. The present study was conducted with the objective of developing a viable somatic embryogenic protocol for leaf calli of tea. Leaf segments of 3 rd leaves of TRI2043 and TRI2024 cultivars were used to produce calli and for induction of somatic embryos 2 nd and 3 rd subcultures were selected. Calli were inoculated in MS media with (i) 2 mgl -1 Benzyl amino purine + 3 mgl -1 Naphthol acetic acid; and (ii) 2 mgl -1 Benzyl amino purine + 3.5 mgl -1 Naphthol acetic acid growth regulator combinations. The greatest amount of embryogenic callus proliferation in both cultivars were achieved from 3 rd subculture using 2 mgl -1 Benzyl amino purine + 3.5 mgl -1 Naphthol acetic acid medium. Compact and friable callus was observed in all culture bottles 3 weeks after culturing and friable calli was reported as the best for the induction of somatic embryos. Somatic embryoids were observed in 2 mgl -1 Benzyl amino purine + 3 mgl -1 Naphthol acetic acid of TRI2043. Significantly highest relative growth rate (92.21%) was observed from leaf callus in 2 mgl -1 Benzyl amino purine + 3.5 mgl -1 Naphthol acetic acid of TRI2024 when using 2 nd subculture (mean value 83.89%). Second subculture of leaf callus in MS medium with 2 mgl -1 benzyl amino purine + 3 mgl -1 naphthol acetic acid is better to induce somatic embryos. 0201-08-24T00:00:00Z http://www.digital.lib.esn.ac.lk//handle/1234/15374 Effect of compost and Expert TM fertilizer on the vegetative parameters of bush beans (Phaseolus vulgaris L. Imthiyas, M.S.M; Seran, T.H A pot experiment was laid out in complete randomized design with seven treatments and three replications to evaluate the vegetative parameters of bush beans cv top crop. Treatments included applications of compost (1-2 kg/m² as basal) and expert M fertilizer (20-30 g/m² (topdressing) at different levels. After 40 days of seeding, fresh and dry weights of leaves, roots and shoots, number of nodules and leaf area were measured and recorded. All the collected data were subjected to statistical analysis. The results revealed that 2 kg/m² compost with 30 g/m² expert fertilizer treatment had higher values in leaf area and plant biomass than other treatments and showed significant differences in most of vegetative parameters. This treatment was statistically similar in its effect on leaf area and plant biomass with 1.5 kg/m² compost and 30 g/m² expert fertilizer treatment. Nodulation was high in 1.5 kg/m² compost than that in 2 kg/m² compost along with 30 g/m² expert fertilizer. Therefore, it would be concluded that 1.5 kg/m² compost with 30 g/m² expert fertilizer application would increase vegetative and reproductive growth of beans than NPK fertilizer alone. 2017-10-06T00:00:00Z http://www.digital.lib.esn.ac.lk//handle/1234/15373 Impact on selected skill development programs on women’s income generating activities in tsunami affected area in Batticaloa district. Seran T.H.; Brintha I,; Balasingham, H.S. Over the past three decades women’s issues and more recently gender issues have gained prominence of the development platform and women play a significant role in household and community service. Households are the first place of gender socialization. Skill is an important aspect in people’s life and it should be considered as a part of their life. Today, it has been challenging for people in view of improving the people’s living status, improving income level and employment opportunities, especially for those who are in the developing nations affected by the tsunami. The contribution of government and non government organizations is highly expected by the people to empower them to face this challenge. In this way, CIDA has joined with Eastern University, Sri Lanka to contribute a lot to improve their living status in the Batticaloa district. Under the CIDA Restore project, skill training was provided to women, who were affected by tsunami in 2004 to raise their income and reduce poverty. The objective of this study was to assess the impact of the training on these women’s lives. Therefore, the conceptualization frame work for this study was developed based on the objective of the CIDA Restore project. It covered four areas such as living standard and income, service quality, self employment opportunity and human development activities. Personal and research information had been collected through structured questionnaires. The five point Likert Scale model of statement was used which ranking from one to five. The questionnaires were randomly issued to participants in Palameenmadu village. The present study revealed that women’s participation in skill training was more (31.3%) in the age group of 21-30 followed by the age group of 31-40 (22.8%). Among the respondents, most of them were married (62.5%) while 27.1% were school girls and 2.1% were women household heads. The main income of the family has declined. According to monthly income obtained before training, 54.2% of respondents had fallen into the family income category of below Rs.3000 but after getting training, it had been reduced by 47.7%. Also it was found that 37.5% of the women surveyed were self employed and 2.1% were working in the NGO sector. It was further noted that, a large number of respondents participated in a combination of sewing techniques and fabric painting (22.9%). Income level has increased after getting skill trainings provided by CIDA at Palameenmadu village. All the variables derived from the data revealed that the women were highly satisfied by the skill training provided by CIDA. Living standard and income, service quality, self employment opportunity and human development activities had mean scale value of 3.98, 4.17, 4.17 and 4.42 respectively. This present study concluded that skill development program under CIDA Restore project had a capacity to strengthen the living status of the rural community. 2009-01-01T00:00:00Z
