以黑龙江省的3个超级稻品种及分别的普通对照品种为材料,采用田间试验的方法进行了茎秆各性状的研究。结果表明:超级稻品种的倒1节间长度和粗度均显著高于的对照品种,而倒2节间和倒3节间均短于对照品种;黑龙江省超级稻品种的穗颈、倒1节间和倒2节间大维管束数均分别高于其同熟期的普通对照;相关分析表明,倒1节间长度、粗度、倒2节间粗、倒3节间粗与穗颈和各节间大小维管束均呈正相关的关系。
Three super rice varieties and their common control varieties in Heilongjiang Province were used as materials to study the traits of stalks by field experiments. The results showed that the length and thickness of down-internodes in Super-rice varieties were significantly higher than those in the control varieties, while that in the second and third inversions was shorter than that in the control varieties. The panicles in the super-rice varieties in Heilongjiang Province were 1 The number of big vascular bundles in internode and internode were both higher than those in normal control. The correlation analysis showed that the length, And the size of each internode vascular bundle were positively correlated.
