| 摘 要： | 以两个有代表性的茭白品种为试材,测定了植株主茎生育过程中地上各部位干、鲜质量的积累及叶片净光合速率的变化。结果表明在田间封行前,植株主茎叶和短缩茎的干、鲜质量持续缓慢增加;封行后至肉质茎快速膨大前,短缩茎的物质积累超过叶片和叶鞘;肉质茎快速膨大期间,干物质积累主要在其前期,同时短缩茎等其余部位干、鲜质量明显下降;之后肉质茎干、鲜质量增加趋缓,叶片、叶鞘质量仍持续下降,而短缩茎质量回升,进入新一轮物质积累期;主茎的总干物质量在封行后迅速提高,在肉质茎充分膨大后下降。功能叶片净光合速率在生育进程中总体呈持续缓慢下降的趋势,肉质茎快速膨大期间迅速大幅上升,紧接着又快速回落。

| Abstract: | The changes of fresh and dry weight accumulation in leaves and stems as well as the net photosynthesis rate of function leaves on main tiller of the Zizania latifolia were studied with two typical varieties at their different growth and development stages.The results showed that,fresh and dry weight of blades,sheathes and culm increased steadily before the gall’s quick swelling period, the accumulation of culm surpassed those of blades and sheathes.Fresh and dry weight of culm and leaves decreased obviously... |
