| 摘 要： | 1983—85年间观察了五个小麦品种地上部伸长节间的大、小维管束数目和面积及其与单穗粒数的关系。结果表明,小麦茎节间维管组织的发育状况因节位、品种、年度气候条件等而异。节间大、小维管束之间在数量上呈极显著的负相关(r=-0.4118)。并证实小麦节间大、小维管束数目与面积和单穗粒数之间呈正相关,但其间密切程度有差异。

| Abstract: | The number of macro-bundles and micro-bundles are complementary each another,and the negative correlation between the two types of bundles is significant (r=-0.4118~(**)) .Thus,the total number of internodal macro-bundles and micro-bundles are more stable than that of macro-bundles and micro-bundles separately.The number and area of internodal bundle tissue of wheat are positively related to the grain number per spike,but the degree of relationship is different among them. In general,there is a trend that the relationship of macro-bundle and the grain number per spike is closer than that of the micro-bundle, and also closer than that of the bundle area; further more, the relationship of the development degree of upper internode bundle tissne and the grain number per spike is closer than that of the lower internode. |
