Abstract: The effects of different plant growth regulators on wheat development and yield were studied through two points experiment. The results showed that MET can decrease the plant height of wheat, but plant protein, 21 albumin, Green storm 2008, Cuixiu, and Labor one had primitives effect on plant height; Besides leaf area per plant of DPC, the other treatments can obviously promote the leaf area per plant and amount of dry matter accumulation; Plant protein and 21 albumin can obviously promote the chlorophyll contents, but a2, a3, a4, PP333, and DPC could obviously promote the chlorophyll contents and cell fluid concentration; Some treatment increased three factors, some treatment increased two factors, and some treatment increased one factor. Generally, 21 albumin, Green storm 2008, Labor one, Enshibao, al, a2, a3, PP333 and DPC could assort the relationship with yield components, it attained high-yield.
