| Abstract | The objectives of this study were to determine color changing of pod and seed germination and vigor of soybean (Glycine max (L.) Merr.) seeds at the physiological maturity (PM). Soybean seeds, cultivar Chiang Mai 60, obtained from Chiang Mai Field Crops Research Center were planted in teh field during dry season. The seeds were sampled every two days form the sixth, seventh, eighth and ninth nodes throughout the maturation process for determination of seed dry weight accumulation, seed moisture, pod and seed color and seed color and seed shrinkage. Germination and vigor of seeds were tested at PM and harvest maturity (HM). In the first period of maximum seed dry weight, it was found that at about 60% moisture content seeds became shrinkage. At this period, loss of green color of pod and seed was not complete. After six days of the first maximum seed dry weight accumulation, the green color from pod vigor of seed at this PM, were substantially higher than those observed at HM. |
