THE EFFECT OF PP333 DPC ON THE GROWTH AND SHOOT STRUCTURE IN ARACHIS HYPOGAEA L.

Spraying with PP333 DPC in Arachis hypogaea L.,the development of its main stem was restrained, internodes were become short and leaf short and narrow. The leaf petiole was become thin, the length of its vascular bundle was increased while the wideneds was decreased distinctively and the mechnical tissue was become thick. The leaf lamina and its main vein were thicker, the palisade tissue was become thick clearly, the length and the wideness of the vascular bundle of the main vein were increased. The leaf,e pidermis cells were become small, the length of stomata was decreased while the wide ness was increased. The number of grana lamella was decreased, indicating that PP333. DPC could restrain the development of chloroplast.
