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里显著正相关(r=0.251~*),与酚反应值呈显著正相关(r=0.250~*).

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 wild rice(75%)and relatively high in indica rice (12.8%).but none of the tested japonica or japonicaclinous materials were found to be tolerant to storage.There was a significant positive correlation between the ageing index of seed and the total scores of morphological index(r =0.251~*).as well as between the ageing index of seed and the scores of phenol reaction(r=0.250~*).
