What plants are sensitive to NaCl?
This study was carried out to evaluate the physiological responses of four selected Cucurbitaceae species to NaCl salinity stress. Four types of Cucurbitaceae viz. cucumber (Cucumis sativa), squash (Cucurbita moschata), bitter gourd (Momordica charantia) and bottle gourd (Lagenaria siceraria) were subjected to four levels of NaCl (0, 25, 50, 75 mM) and data on growth – leaf area, leaf number, stem diameter, plant height, plant dry matter and concentration of leaf and root Na were collected. In terms of growth, bitter gourd had the lowest reduction of leaf area, plant height and stem dry weight while cucumber had the highest reduction of leaf area. Total reduction of plant dry matter as salinity increased to 75 mM NaCl was the least in bitter gourd, 44.40% and the highest in cucumber, 67.84%. As salinity levels increase from 0 to 75 mM, Na+ concentrations in roots in bitter gourd had the highest increase; 5.71 times, while increment in squash, cucumber and bottle gourd were only 2.89, 2.59 and 2.57 respectively compared to control. Na+ concentrations in leaf in bitter gourd had the lowest increase (8.00 times) compared to squash, cucumber and bottle gourd which increase by 19.00, 11.50 and 9.50 times, respectively. In conclusion, based on reduction in plant dry matter and accumulation of Na ions in leaf, bitter gourd was least salt-sensitive while cucumber was most salt-sensitive, compared to other species tested. The level of salt-sensitive between the species from least sensitive to most sensitive is bitter gourd >bottle gourd>squash>cucumber.
Is Bangladesh a food safety concern?

What is Ethylene?
Fruit ripening is the set of processes that occur from the later stages of growth and development until the fruit is ready to be consumed. Fruit ripening results in changes in fruit quality characteristics. The firmness of the fruit flesh typically softens, the sugar content rises, and acid levels are reduced.
