Abstract
The effect of exogenous phytic acid application on rice grain yield and quality was investigated by foliar spraying at six concentrations during mid and late growth stages with the hybrid rice Zhongzheyou 1as material.The results showed that rice grain yield per plant increased by 4.1%-9.8% under foliar spraying of phytic acid at various concentrations,economic coefficient and plant height increased,but panicle length shortened,dry matter weights of main organs per plant at mature period dropped,moreover,quality traits such as brown and head milled rice rate,grain chalkiness increased,but milled rice yield,rice starch alkali digestion value and gel consistency descended,the contents of amylose and protein varied discrepantly. However,the effect of exogenous phytic acid spraying was not concentration-related but application stage-related on seed setting rate,1000-grain weight,dry matter weight,economic coefficient,head milled and brown rice rates,grain chalkiness,rice starch alkali digestion value,protein content etc.The results indicated that foliar spraying of phytic acid at concentration of 0.25%-0.5% contributed to the improvement of rice grain yield and quality at the full heading or the grain filling stages.
