Abstract:
为了解光质及内源激素对黄瓜幼苗形态建成的影响，并向设施栽培育苗过程中光源的合理配置提供理论依据，采用发光二极管（light-emittingdiode，led）精确调制光谱能量分布，以白光为对照（ck），研究红、蓝、黄、绿4种单色光质下黄瓜幼苗叶片和下胚轴中赤霉素（ga3）、生长素（iaa）和脱落酸（aba）含量的变化.结果表明：不同光质可能通过调节内源激素的分布来影响黄瓜幼苗的光形态建成.红光和蓝光通过影响iaa的极性运输，影响真叶的生长进程，其中红光显著促进了iaa的极性运输，叶片中iaa含量仅20?gg-1，而下胚轴中iaa含量却高达120?gg-1；黄光处理下叶片中ga3含量高（约为对照的2倍），抑制叶片脱黄化，并引起叶片卷曲.各单色光质下黄瓜幼苗下胚轴与对照相比均有不同程度伸长，说明光对幼苗下胚轴的抑制作用可能是各种光质共同作用的结果.黄、绿光处理下胚轴中ga3含量显著升高，aba含量显著降低，下胚轴显著伸长；红光引起下胚轴中ga3和aba含量显著升高，但下胚轴长度增加不明显，黄瓜幼苗下胚轴的伸长可能与光质调节ga3和aba的相对水平密切相关.综上所述，不同光质对黄瓜幼苗中内源激素含量的变化影响显著，从而引起了幼苗形态特征的显著变化.
