The content and composition of storage protein, which were controlled by genetic factors, environment and cultivation techniques, are important index to evaluate rice quality and nutrition value. Panicle fertilizer obviously enhanced crude protein content of matured rice grain, but the impact on the relative content of each component was not significant. High temperature stress significantly changed the dynamic process of the accumulation of storage proteins components, the components soluble in dilute acid or dilute alkali, including more than 57 kD polypeptides (which is considered a precursor of glutelin or protein polymer), maintained a high level from the beginning of filling stage. After high temperature stress, the glutelin of matured seeds were existed in state of high molecular polymer, and the contents of glutelin monomer and prolamin were reduced.
