Abstract:
The experimental results showed that the assimilating tissue became denser, thickness of palisade and spong tissues were increased, palisade cells became longer, but thickness of warer storage tissue slightly decreased after spraying of PP333 on the leaves of peanut.Chloroplast structure in new leaflet emerging after PP333 treatment was changed.The numbers of grana and grana lamellae was increased.The number of mitochondria close to chloroplast was significantly increased.PP333 enhanced the lodging resistance of stem due to the reduction of plant height and the increase of vascular bundle the number of trachea and the thickness of trachea wall in the mainstem.Length of epidemic cells,cortex cells and pith cells of main stem in longitudinal section were reduced.
