This observation provided a strong support to the point that most leaves export the most of assimilates in the light time. Plasmodesmal densities between SE/CC, CC/PP, PP/PP and PP/BSC (bundle-sheath cell) decreased in weak light. Plasmodesmata were observed between CC/SE (nacreous-walled sieve element), PP/BSC in branch veins in normal light intensity, but not in weak light. Thus apoplasmic pathway may be the main mode of transport of assimilates in weak light, however symplasmic pathway may be the main mode of transport of assimilates in normal light intensity.
在筛管/伴胞、伴胞/韧皮薄壁细胞、韧皮薄壁细胞/韧皮薄壁细胞和韧皮薄壁细胞/维管束鞘细胞之间的胞间连丝密度都在弱光条件下下降，在正常光照强度下支脉筛管/伴胞和韧皮薄壁细胞/维管束鞘细胞之间可以观察到胞间连丝，而在弱光下几乎观察不到胞间连丝的存在，所以同化物的运输在弱光条件下可能以质外体运输为主，而在正常光照强度下，共质体运输可能是主要的运输方式。

Experimental results show that there are existing some indifferent mechanisms to the pollen sterilization of the Ms types: during the period of single nucleic to three nucleic pollen cell,we observed that the cell of xylem and phloem in anther septum abnormally developed,also the cell in the sheath of vascular bundle,smaller and arranged irregularly; the metabolic block developed too,es...
结果表明，不育类型的花粉败育有着一些共同的机理：在花粉单核期至三核期可见到花药隔维管束的木质部及韧皮部细胞发育较差，维管束鞘细胞发育不良，体积较小，排列紊乱；在单核花粉期至三核花粉期均发生物质代谢障碍，特别在花药部位尤为明显；由于维管束发育不良和花药物质代谢障碍，导致了花粉缺乏营养而败育。
