有芒小麦芒与穗粒重的关系研究

Study on the Relationship between the Awn Length and Grain Weight of Awned Wheat

为了探索有芒小麦穗间芒长与粒重的关系,选取66个小麦品种,对不同基因型小麦芒长,芒黄速率与穗粒数、穗重以及千粒重之间关系进行了研究。结果表明,芒长与穗粒数、穗重呈正相关,与千粒重呈负相关,线性关系不显著。芒黄速率与穗粒数呈负相关,与穗重、千粒重呈正相关,线性关系不显著。

In order to explore the relationship between the awn length and grain weight of awned wheat, 66 wheat cultivars were selected, the relationships between their awn length, awn yellowing rate and grain number per spike, spike weight and 1 000-grain were studied. As indica- ted by the results, the awn length is positively correlated with the grain number per spike and the spike weight, while negatively correlated with the 1 000-grain weight without significant linear regions. The awn yellowing rate is negatively correlated with the grain number per spike, while positively correlated with the spike weight and the 1 000-grain weight without significant linear relations.
