Abstract
玉米屬旱地作物,種子發芽對浸水的反應相當敏感,種子的萌芽能力隨著浸水期間的延長而降低萌芽率.氧氣缺乏為浸水下玉米萌芽降低的主要原因,王米生長發育期間以幼苗期(v3-v5)對浸水溼害最為敏感,根部的生長.生理活性.呼吸作用和植株生長均受到明顯抑制,葉片 PEPCase (PEPcarboxylase)活性與葉緑素含量(Chlorophyllcontent)均明顯下降,對籽粒產量影響很大. Maize (Zea mays )originater grom subtropical regions and often cultivates in upland field. The experimental results indicated that the emergence of corn seed was highly susceptible to flooding,and more damages as flooding period increased.
