| 摘 要： | 通过自然低温鉴定,从84份水稻核心种质中初步筛选出13份苗期抗寒材料,其中包括3份籼稻和10份粳稻品种.在光照培养箱中进一步的低温处理结果表明:在较长时间的持续低温胁迫条件下,抗寒材料的抗寒级别分别达到1～4级,其中粳87-304达到1级;在低温变温处理的条件下,低温敏感品种三百粒和加巴拉植株的叶片枯萎、恢复室温后缓慢...

| Abstract: | 13 rice germplasm displaying cold resistance at seedling stage including 3 Indica varieties and 10 Japonica varieties have been identified from 84 varieties in Micro-core Rice Collection screened by natural low temperature.Further cold treatment in climate chamber showed that cold resistance of above 13 rice germplasms reached level of 1 to 4,of which Japonica 87-304 reached level 1 under continuous low temperature treatment.In altered low temperature condition,the leaves of cold sensitive varieties Sanbail... |
