摘要:
在长、短两种光周期条件下对新铁炮百合的三种生理指标进行了测定。结果表明:新铁炮百合上、中部叶片的生理活动与植株生长发育状态的关系较为紧密;顶芽形态分化初期,上、中部叶片可溶性糖和淀粉含量降至较低的水平,而总氮含量则升至较高水平;此外,生殖生长状态下,3部分叶片各自C/N值均高于营养生长状态下其各自C/N值。
Abstract:
Three physiological indexes of Lilium formolongi under long day and short day conditions were studied. The results were as follows:physiological activities of the upper and middle part leaves had close relation with growth and development state of plant. For the upper and middle part leaves,soluble sugar and starch indexes decreased to a lower level,while total nitrogen index increased to a higher level at initial stage of bud morphological differentiation. Moreover,each C/N index of three parts leaves in reproductive growth state was higher than each C/N index of three parts leaves in vegetative growth state.
