ＰＰ３３３处理可使小麦叶片的表皮细胞、保卫细胞和叶肉细胞体积显著减少；增加叶片内叶肉细胞的层数和叶脉的机械组织的细胞层数，并可加强叶肉细胞的环型结构，使叶肉细胞之间的排列更加紧密。ＰＰ３３３处理对小麦叶片内叶绿体超微结构的影响表现为叶绿体内基粒数明显增多，高片层垛叠的基粒数比例增加，基质片层较为完善，基质内电子密度较浓，类囊体膜系统的发育进程明显加快。ＰＰ３３３处理可显著提高叶片的叶绿素含量，增加叶片的净光合速率，并延长叶片的光合功能期。
PP333 treatment can significantly reduce the volume of the epidermal cells, guard cells and mesophyll cells in wheat leaves; increase the number of mesophyll cells and the mechanical layers of the veins in the leaves, and can strengthen the ring structure of mesophyll cells, mesophyll cells The arrangement between the more closely. The effect of PP333 treatment on the ultrastructure of chloroplast in wheat leaves showed that the number of chloroplasts in the chloroplast increased obviously, the proportion of the basal grains in the high lamellar layer increased, the stroma lamellae were more perfect, the electron density in the stroma was stronger, Membrane system development significantly accelerated. PP333 treatment could significantly increase the chlorophyll content of leaves, increase the net photosynthetic rate of leaves and prolong the photosynthetic period of leaves.
