水稻茎秆抗倒伏研究
Lodging Resistance of Stems in Rice ( Oryza sativa L.)
摘要
Abstract
[Objective] The paper was to explore the relationship between character of rice stem and compressive strength. [Method] The morphological and anatomical characters of stems of 10 rice varieties (including three internodes) were systematically studied by paraffin sectioning technology; the digital force tester was used to measure the compressive strengths of various varieties; the correlation between above-mentioned characters and stem compressive strengths was analyzed. [Result] Correlation analysis showed that the outer diameter and cross-sectional area of stem had close relation with longing resistance of stem,which could be adopted as the important factors for stem longing resistance. The outer diameter and cross-sectional area of 63 Liangyou 636 was significantly higher than other tested varieties, three internodes all had high compressive strength,and the yield was also high. [Conclusion] 63 Liangyou 636 could be used as the rice cultivar with super yield.关键词
