| 摘 要： | 对68份不同进化阶段的稻种资源的储藏特性进行了初步分析,结果表明:供试材料中耐储藏性好的材料有10份(占14.71%),主要为野生种和地方品种,耐储藏性很差的材料有5份(7.35%);野生种中耐储藏材料的比例最高(75%),在籼型材料中耐储藏材料的比例较高(12.8%),在粳型和偏粳型材料中未发现耐储藏的材料。种子老化指数与籼粳形态指数总分值呈显著正相关(r=0.251*),与酚反应值呈显著正相关(r=0.250*)。 |

| Abstract: | The storage characteristics of 68 accessions of rice germplasm in different evolutional stages were studied.The results showed that there were 10 accessions or 14.71% of the tested rice genetic resources had a good tolerance to storage,and these storage-tolerant resources were mainly from wild rice and local rice cultivars.There were 5 accessions or 7.35% of the tested rice genetic resources had a very poor tolerance to storage.It was found that the percentage of storage-tolerant materials was highest in wi... |
