“…Seed hydration–dehydration cycles (differing in duration and number) have been investigated intensively at the physiological level. Approaches include soaking–drying, moisture equilibration–drying, and moist sand conditioning–drying [ 12 ]. Hydration–dehydration cycles can maintain or enhance seed vigor and viability [ 6 , 13 , 14 , 15 ], improve seed storability, and improve resistance to some stressors (e.g., heat shock and salt stress) [ 12 , 16 , 17 , 18 , 19 ].…”

Hydration–dehydration cycles can frequently cause stress to seeds, but can also be used to improve germination. However, the molecular basis of the stress caused is poorly understood. Herein, we examine the effects of hydration–dehydration cycles on seed viability and profile the membrane glycerolipid molecular species. We find that seed viability was not affected during the first two cycles, but significantly decreased as further cycles were applied, until all viability was lost. The abundances of seven glycerolipid classes increased and decreased through hydration and dehydration, respectively, but the phosphatidic acid and diacylglycerol abundances changed in the opposite sense, while total glycerolipid contents remained constant. This suggests that during hydration–dehydration cycles, turnover of glycerolipid metabolite pools take place, while no significant lipid synthesis or degradation is involved. As further hydration–dehydration cycles occurred, lipid unsaturation increased, plastidic lipids decreased, and phosphatidylserine acyl chains lengthened. The latter two could be lethal for seeds. Our findings reveal a novel model of membrane lipid changes, and provide new insights into the responses of seeds to hydration–dehydration cycles.

This study was conducted to determine the effect of industrial effluents on seed germination and seedling growth of some leafy vegetables under pot culture condition. Waste water sample was collected from natural gas fertilizer factory Limited, Fenchuganj, Sylhet. Four different leafy vegetables were selected as test crop to grow using these effluents. The design of the experiment was randomized complete block. The effects of different concentration of effluent were compared to that of distilled water (control). The results revealed that different concentrations of the extract caused significant inhibitory effect on germination and root elongation but benefited the shoot elongation. Maximum reduction in germination and root length was observed with the increase in effluent concentration, but increasing the shoot length. Bioassays indicated that the effects were proportional to the concentrations of the effluents and higher concentration showed stronger effect. Different physicochemical parameters of water e.g. pH, temperature, conductivity, dissolved oxygen (DO), chemical oxygen demand (COD), turbidity, Total dissolve solids (TSS), total suspended solids (TSS) etc. of the sample was also analyzed. It was found that the values were far apart from the optimum values that require for safe aquatic environment to establish an aquatic ecosystem on water body. It can be concluded that polluted water is becoming a threat for the crops and also for aquatic environment with the passage of time as more and more wastes are becoming a part of it.
