白皮小麦品种间穗发芽敏感性有极显著的差异。白皮小麦品种中穗发芽敏感性有三种类型,即以种子深休眠为主要机制的低敏感型、以种子浅休眠和穗部因子保护作用为机制的中敏感型和高敏感型。黄熟期水层纸巾穗发芽7天试验,方法简便而高效,适用性好,能兼顾多种机制抗穗发芽材料的筛选鉴定。本文还对白皮小麦抗穗发芽育种选择指标进行了探讨。
There was a significant difference in sprouting susceptibility between white wheat varieties. There are three types of susceptibility to white spike germination in white wheat, which are the low sensitive type with the main mechanism of deep dormancy of seeds and the medium sensitive type and high sensitive type with shallow dormancy and spike factor protection. Yellow maturing water tissue towel sprout 7 days test, the method is simple and efficient, good applicability, can take into account a variety of mechanisms of spike sprouting material identification. The paper also discussed the selection index of white-wheat resistant to spike breeding.
