Studies on optimum moisture content and heat-stable protein of rice seeds stored at room temperature
通过使用在不同气候区室温保存8年的两个不同类型水稻品种，测定水稻室温贮藏的最适含水量，以及在贮藏过程中种子中的热稳定蛋白的变化。通过发芽试验和热稳定蛋白的测定，比较贮藏8年后种子的发芽率、活力指数和热稳定蛋白的变化。在北京地区贮藏种子，籼稻桂早2号（Oryza sativa L. ssp. indica Kato）最适种子含水量为5.5%～6.0%，而粳稻幸实（Oryza sativa L.ssp.japonica Kato）为6.5%～7.0%。在南昌地区，籼稻最适种子含水量为4.5%左右，而粳稻为5.5%～6.0%。耐超干的籼稻品种桂早2号种子中有一条分子量为39.4 kD的特异性蛋白条带...

The project investigated rice’s optimum seed moisture content (MC) in storage at room temperature. It also looked at the change of seed heat-stable protein using two rice cultivars stored in different climate zones for 8 years. The optimum seed MC and the change of seed heat-stable protein after storage for 8 years were compared using germination tests and heat-stable protein determination. The results showed that the optimum seed MC in Beijing was 5.5～6.0 for Indica cultivar Guizao 2 (Oryza sativ |
