| 摘 要： | 通过７个不同生态型的小麦品种在郑州４ａ１６个春、秋播期中的生育表现,提出了不同生态型品种在不同播期中的主茎叶片数,主茎叶龄等指标。如在秋播条件下的主茎叶片数春性品种为１２片,半冬性品种１３片,冬性品种１４片;主茎生长锥伸长时叶龄春性品种为３片左右,半冬性品种为４片左右,冬性品种为５片左右。

| Abstract: | Wheat varieties with different ecotypes were studied in Zhengzhou for 4 years in succession.The plant morphological and ear developmental indices of varieties of different ecotypes were presented in the light of the developmental expression of varieties in 16 spring and autumn sowing times and the earring circumstances in spring sowing times.The leaf numbers of main stem are 12 for spring varieties sowed in autumn,13 for semi winter varieties,and 14 for winter varieties.The leaf ages at the begin growing period of main stem are 3 for spring varieties,about 4 for semi winter varieties,and about 5 for winter varieties. |
