华南优质稻花期耐热性鉴定研究
|
摘要
在人工气候室模拟水稻抽穗扬花期高温热害胁迫,以高温胁迫下的结实率和相对结实率为评价指标,对40个华南优质稻品种材料的耐热性进行评价。结果表明,品种材料间耐热性与产量潜力存在显著差异;N22、黄华占、HQ5、桂1025、广恢998、金香糯的耐热性强,粤晶丝苗2号、SH14、力源占2号、柳沙油占202、玉桂占的耐热性为中等,OM4900、882H、93-11等为高温敏感型品种。
Heat resistance during heading-flowering was evaluated with 40 high quality rice combinations under high temperature conditions in phytotron. Heat tolerance of rice varieties was evaluated using seed setting rate and relative seed setting rate under high temperature. The result showed that, there are significant differences in heat tolerance and yield potential among varieties, N22,Huanghuazhan, HQ 5, Gui 1025, Guanghui 998 and Jinxiangnuo are heat tolerant combinations; Yuejingsimiao 2, SH14, Liyuanzhan2, Liushayouzhan 202 and Yuguizhan are semi-heat tolerant combinations; OM4900、882 H、93-11 and the others are heat sensitive combinations.
