Madhupur Sal (Shorea robusta) forest, the largest belt of natural Sal forest in Bangladesh, is rich in ecological resources and biodiversity. In recent years, human disturbance leads to biodiversity loss from the forest, and it has a successive effect on the services that the forest provides. Thus, it is crucial to explore the present condition of the forest’s available ecosystem services with local people’s consciousness about the ecosystem. The present study investigated the available ecosystem services of Madhupur Sal forest, respondents’ perception towards those services and the socio-demographic characteristics of the respondents that influenced their perception. Data were collected by interviewing 90 respondents with a focus group discussion. Most of the respondents in the study area were ethnic people (Garo). A total of 20 ecosystem services were identified where soil erosion control, mental peace and maintenance of soil fertility were the top-ranked services. About 83% of the respondents had moderately favorable perception towards ecosystem services. The study results showed that the respondents with a higher level of education, higher family annual income, and more training received on agriculture perceived ecosystem services to a greater extent than others. So, improvement of their perception towards ecosystem services can make them aware of forest biodiversity conservation.

Soil salinity, a major environmental concern, significantly reduces plant growth and production all around the world. Finding solutions to reduce the salinity impacts on plants is critical for global food security. In recent years, the priming of plants with organic chemicals has shown to be a viable approach for the alleviation of salinity effects in plants. The current study examined the effects of exogenous ethanol in triggering salinity acclimatization responses in soybean by investigating growth responses, and numerous physiological and biochemical features. Foliar ethanol application to saline water-treated soybean plants resulted in an enhancement of biomass, leaf area, photosynthetic pigment contents, net photosynthetic rate, shoot relative water content, water use efficiency, and K+ and Mg2+ contents, leading to improved growth performance under salinity. Salt stress significantly enhanced the contents of reactive oxygen species (ROS), malondialdehyde, and electrolyte leakage in the leaves, suggesting salt-induced oxidative stress and membrane damage in soybean plants. In contrast, ethanol treatment of salt-treated soybean plants boosted ROS-detoxification mechanisms by enhancing the activities of antioxidant enzymes, including peroxidase, ascorbate peroxidase, catalase, and glutathione S-transferase. Ethanol application also augmented the levels of proline and total free amino acids in salt-exposed plants, implying a role of ethanol in maintaining osmotic adjustment in response to salt stress. Notably, exogenous ethanol decreased Na+ uptake while increasing K+ and Mg2+ uptake and their partitioning to leaves and roots in salt-stressed plants. Overall, our findings reveal the protective roles of ethanol against salinity in soybean and suggest that the use of this cost-effective and easily accessible ethanol in salinity mitigation could be an effective approach to increase soybean production in salt-affected areas.

Introduction: An experiment was conducted to study combining ability and heterosis for yield and related traits in chili during November 2015 to September 2017. Materials and Methods: The experimental material consisted of six parents and their fifteen F1’s developed by half diallel mating design. Analysis of variance for combining ability exhibited significant General and Specific Combining Ability (GCA and SCA) effects for all the characters studied. Results: The SCA variance was higher than GCA variance for all the traits except ten fresh fruit weight, fruit length and fruit width indicating the predominance of non-additive type of gene action. The parents P1 and P6 were identified as the best general combiners and the hybrids P1×P6, P1×P4 and P2×P5 were identified as the best specific combinations for fresh fruit yield per plant and related traits. The hybrids P1×P6, P1×P4 and P3×P6 showed significant average heterosis and heterobeltiosis for fresh fruit yield per plant and its related traits. (H1/D)0.5 ratio indicated partial dominance effect of genes for all the traits. Conclusion: Therefore, it may be possible to take advantages of better heterotic effects to be fixed in the later generations to facilitate further selection and best specific combinations for development of the hybrid variety of chili which can help to increase the total production in Bangladesh.
