Effect Of Exogenous Regulators On the Metabolism Of Biochemical Constituents In Some Plants

The aim of this study is to investigate the dwarfing effect of both CCC and B-9 on some high maize CVS. (Giza 2 and Cairo 1) alongside with the other chemical effects either on the metabolism in leaves or on the biochemicl constituents of grains. in other word it is aimed to find the proper hoemone treatment which induces a desirable reduction in stem length of the new maize cultivars which enables them to aviod lodging.at the same time this treatment should be either favourabie to or an effective on the plant yield .
