Cloning of a group 3 Lea cDNA from tworow barley;

二棱大麥LEA cDNA的克隆與測序

The results showed that accumulated temperature before wintering mainly affected single ridge stage and double ridges stage of spike differentiation.

結果表明,隨著冬前積溫的減少,不同幼穗分化時期累積GDD減小,冬前積溫對小麥幼穗分化的影響主要表現在單棱期和二棱期,護穎分化期后幼穗分化受冬前積溫的影響較小,冬性品種幼穗分化累積GDD對冬前積溫最敏感,半冬性品種次之,春性品種則對冬前積溫不敏感。

) were used for investigating effects of sowing dates and vernalization treatments on corresponding relation between leaf appearance and double ridges stage,and glume stage of spike differe.

為解析小麥葉片出生與小穗原基分化的同步關系,為營養器官生長和幼穗分化的協調發展、苗情診斷和培育壯苗提供理論依據,以16個小麥品種為試驗材料,采用室內春化處理和田間分期播種的方法,研究春化處理和播期對不同春化發育特性小麥品種葉片出生與壯苗冬前安全穗發育期(二棱期)和護穎分化期對應關系的影響。
