Effects of silicon on seed setting rate of rice intersubspecific hybrids

W. - C. Li, Zhang, L., Wang, J., Wang, D., Wang, T. - X., and Duan, C. - X., Effects of silicon on seed setting rate of rice intersubspecific hybrids, vol. 14, pp. 10359-10364, 2015.

The present study found semi-sterility in rice intersubspecific hybrids of ‘Taichung 65’ x ‘Guangluai 4’ and ‘Ludao’ x ‘Qiuguang’. Embryo sac fertility was evaluated using the overall staining transparent method. The results showed that the embryo sac contained a normal egg cell, normal synergid cells, polar nuclei cells, and antipodal cells, indicating that semi-sterility was caused mainly by pollen semi-sterility. In the pot experiment, the effects of silicon on the seed-setting rate of the two intersubspecific hybrids were examined.
