摘要：

本研究以黑龙江省的3个超级稻品种及分别的普通对照品种为材料，进行了茎秆各性状的研究。主要结论如下：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。

Abstract:

To study on stem traits and correlation among them, 3 super rice varieties of Heilongjiang province were studied in this experiment, and 3 common varieties were used as contrast respectively. The main results were as follows: Compared with contrasts, length and diameter of the 1st internode of super rice varieties were higher, and 2nd and the 3rd internode of super rice varieties were lower. It were more than contrasts that the number of large vascular bundle of neck-panicle, the 1st internode, the 2nd internode of super rice varieties. Correlation analysis indicated that the number of large and small vascular bundle of neck-panicle and other internodes had positive correlation with length and diameter of the 1st internode, diameter of the 2nd internode and the 3rd internode.
