Effects of Seed Storage Conditions on Biochemical Changes of Freshly Harvested High Moisture Undried Rice Seeds cv. CO 51

Effect of Storage Temperature and Moisture Content on Seed Quality, Plant Establishment and Grain Yield of Cowpea

“…Evidence of photosynthesis, and protein synthesis (Malhotra et al, 2018). During the period of storage, when vigour and later germination decline, many physiological and biochemical changes occur (Marthandan and Jerlin, 2017). It has been found that a decrease in the integrity of the cell membrane is the first change to occur during ageing as revealed by the increase in solute leakage that occurs from aged but living tissues.…”

“…DMRT respiratory changes during ageing has also been strongly linked with vigour levels in seeds during ageing. A decline in early respiratory activity, increased leakage of electrolytes, and loss in seed dry weight were observed in soybean seeds subjected to accelerated ageing and in soybean seeds stored at 25 ºC, respiration rates of mitochondria from axes decreased as leachate conductivity increased (Marthandan and Jerlin, 2017). Thus, the reduction in vigour observed in the stored cowpea seeds was related to the damage to weak embryonic cells, and therefore destruction of enzymes, genetic constitution, respiratory activities and protein synthesis required for germination and seedling growth.…”

Studies on Effect of Micronutrients on Seed Quality Parameters in Paddy (Oryza sativa. L)

“…Hasan et al, 2016 also concluded that paddy seed primed with ZnSO 4 (3.0 %) for 30 hours, resulted in highest germination percentage and the lowest mean germination time. Marthandan et al, 2017 reported that undried rice seeds at high moisture stores under cold storage is found to be best as compared to ambient storage condition. The enzymes which help the storability of seed was maximum in undried and dried seeds stored under cold storage condition viz., Dehydrogenase (0.174 and 0.773 OD value) amylase (1.38 and 1.43 mg).…”
