南粳44植株抗倒伏能力的研究
Study on Lodging Resistance of Japonica Rice Variety "Nanjing 44"
摘要
Abstract
Taking the lodging - susceptible strain "Ning 7412" as the check, the author studied the lodging -resistant mechanism of the japonica rice variety " Nanjing 44" from the aspects of morphology and physiology. The results showed that: comparing with " Ning 7412" , the basal second and third stem internodes of " Nanjing 44" was shorter, wider, thicker and better filled. The contents of SiO2 , calcium and soluble sugar in the mature stem of "Nanjing 44" were significantly higher than those of "Ning 7412" , while the content of K20 of "Nanjing 44" was significantly lower than that of "Ning 7412". The epidermis and basic tissue of the basal stem internodes of "Nanjing 44" had more and thicker cell lays and vascular bundles than those of "Ning 7412", so the lodging resistance of "Nanjing 44" was better than Lhat of "Ning 7412".关键词
