After analyzing glutinous rice waxy gene sequence reported by previous studies, two pairs of dominant and codominant STS molecular markers based PCR were designed for distinguishing glutinous rice, according to the distinctions between glutinous rice wx gene and nonglutinous rice Wx gene. Moreover, the whole sequences of the two Wx genes of nonglutinous rice reported by others were also aligned, and another two pairs of dominant STS molecular markers were designed to discriminate Wxa from Wxb based on the special site between the two genotypes. Then, corresponding rice genotypes were identified by the established new markers.

Effect of protein and lipid in rice on starch physicochemical characteristics, difference between the region of non-chalkiness and chalkiness of rice, dynamic variation of cell structure and CaM distribution on rice spike were expounded in this study. It was found that protein and lipid in rice had important effect on starch gelatinization, there were distinct differences between the region of non-chalkiness and chalkiness of rice, vascular bundle system in rice spike was changed during grain filling, difference quality of different position of rice spike was more distinct in dense spike rice for more powerful vascular bundle system, the development of rice seeds was corresponded to pericarp development, difference quality of different position of rice spike was also related to transport function of rachilla besides activity of "source", and calmodulin relative activity was closely related to grain filling velocity and enginery properties.

In addition, the hypha could also invade the rice root.3黄片子大全、Making clear the effects of silicon on the resistance to sheath blight and rice growth.Sodium silicate was added into the nourishing in the entire growth period and short period of rice, after being inoculated with R.solani, the rice with application (the Si+ rice) of resistant cultivar 91SP and Teqing had lower (but not statistically significant) disease rating and disease index with relative control effect of 10.02% and 8.70% compared to the Si- rice plants in, but the Si+ rice plants of susceptible cultivar Lemont and Ningjing 1 had significantly lower rating and disease index with relative control effect of 27.42% and 24.29% compared to the Si- rice plants. The results indicated silicon could strengthened the resistance to rice sheath blight, specially strengthened the resistance of susceptible cultivar Lemont and Ningjing 1 remarkedly.
