根据1962及1963两年,对于冬小麦农大183,在不同播期条件下,分蘖、叶片及穗部等性状的观察资料,分析了主茎、分蘖、叶片及穗部之间的关系;论述了分蘖或在组成小麦群体中的地位;各级分蘖成穗率及其经济性状的比较;叶片的功能期;叶龄与分蘖力的关系;主穗与分蘖穗在穗分化上的差异;穗群分化及叶龄指数和叶龄余数与穗分化的关系。文中还初步提出了根据主茎叶片数目,推算分蘖节数目、分蘖叶片数目及单株分蘖力的经验公式。
According to the observation data of tiller, leaf and ear under different sowing date in 1962 and 1963, the relationship between main stem, tiller, leaf and ear was analyzed. The tiller Or in the composition of the wheat population; at all levels of tillering spike rate and economic traits comparison; leaf functional period; leaf age and tillering capacity; main spike and tillering panicle in the spike differentiation; ear cluster differentiation And leaf age index and leaf age residue and ear differentiation. In the paper, the empirical formulas of the number of tillers, the number of tillers and the tillering ability of individual plants were also proposed based on the number of main stem leaves.
