| 摘 要： | 以4个耐热性存在差异的菜心品种(系)作材料,在盛夏高温和非高温季节种植并测定和分析这些菜心材料的产量及农艺性状,以期发现一些与耐热性相关的农艺性状.研究结果表明,高温胁迫下耐热性强的菜心材料产量明显高于耐热性弱的菜心材料,具有较高的生物量、薹质量、薹粗、薹叶数和植株最大开展度等农艺性状.相关性分析表明,高温胁迫下菜心的...

| Abstract: | Taking four flowering Chinese cabbage cultivars with different heat tolerance as materials,the yields and agronomic traits of the cultivars planting in the high temperature season and in autumn were measured and analyzed,to find out the agronomic traits related to the heat tolerance.The results showed that the yields of the heat tolerant genotypes were significant higher than that of the heat sensitive genotype under the heat stress condition,and they had higher biomass and stalk weight,larger plant diamete... |
