Seed hygroscopicity and longevity in rice cultivars (Oryza sativa L.) differing in amylose content [Philippines]
1985
Credo, F.R.
Seed hygroscopicity and longevity studies in rice cultivars varying in amylose contents were conducted to determine differences in water absorption and viability patterns. Relationship between amylose content and the various parameters were also made. Although rice cultivars exhibited the same rates of water absorption and desorption they exhibited differences in equilibrium moisture content value at 15 and 80% relative humidity levels and in germinability and vigor under accelerated ageing conditions. Equilibrium moisture content was negatively correlated with amylose content. Germinability and vigor showed no correlation with amylose content at any sampling date, although they were affected by seed moisture levels. Amylose content is not a good basis for grouping when considering storability. Scanning electron micrographs revealed no cultivar differences in terms of surface geometry of the starch granules
