Three plant growth regulators (9,10-Propyl dihydro jasmonate, Brassica napus and 5-Aminolevlinic acid) were sprayed for Yangdao No. 6, Liangyoupeijiu and Shanyou 63. The results as follows: Different regulator had different affect on rice quality. BR and ALA caused decreasing of the head rice rate and increasing of chalky rice rate, while PDJ enabled the head rice rate to increase, and chalky rice rate to decrease in a certain degree. Different density of ALA caused the decreasing of the head rice rate, and the increasing of the chalky rice rate as well as chalkiness. All of them could improve the ratio of ripened grain and the 1000 grains weight of varieties. The gel consistency in hybrid rice increased, which opposite to routine rice. The amino acid content of brown rice rate varies.
