Viability and respiration rate of Glycine max L. cv. SJ.4 seeds
1985
Somchit Moongklang
The percent germination and respiration rate, at the 15th hour after the beginning of germination, of the seeds which stored in different conditions were decreased in different rates. Seeds with low moisture content (9 percent) decreased slower than seeds with high moisture content (12.5 percent). Seeds which stored in cold room (5 +- 1C) decreased slower than stored at room temperature (30 +-2C). The percent germination and respiration rate of the low moisture content seeds stored in cold room (9 percent moisture content and 5C) decreased slower than other three conditions. The percent germination was 75 and respiration rate was 162.52 microliter/hr/gm dry weight after 20 weeks of storage. Seeds with high moisture content and stored at high temperature (12.5 percent moisture conte1153nt and 30C) decreased the percent germination and respiration rate rapidly. The percent germination was decreased to zero in only 14 weeks of storage. When percent germination and respiration rate were greatly decreased, the RQ increased. The decrease in rate of respiration during the germination and percent germination were highly significant correlated and had the coefficient of correlation of 0.
