直立品系小冠花植株性状及其与产量的相关分析

Dynamic study on the plant characters of erect crownvetch strain and the correlation analysis with yield

对3个小冠花品种(品系)(直立品系小冠花、匍匐品系小冠花、‘绿宝石’小冠花品种)在同一环境条件下的生育期、生物量及其相关性状的动态变化特征进行了比较研究.结果表明:直立品系小冠花有更长的青绿期,各时期株高显著高于其他2个品种(系);自5月底开始,直立品系小冠花茎粗、节间长和侧枝长均大于其他2个品种(系);叶面积在6月底之前持续增加,之后开始下降,但始终大于其他2个品种(系);生物量与其相关性状株高、茎粗、节间长、叶面积呈极显著正相关.

Dynamic studies on the growth period,biomass and other growth relative characters of three crownvetch cultivars（strains） under the same condition were compared.The results showed that the erect crownvetch strain had longer green-time and plant height was significantly higher than that of the other two cultivars（strains）;since later of May,the amount of stem diameter,internode-length and side branches-length was larger than that of the other two cultivars（strains）.The leaf areas of erect crownvetch strain continuous increased before the later of June and then decreased,which was bigger than that of the others.The biomass was positively and significantly correlated with plant height,stem diameter,internode-length and leaf areas.
