为了解不同南瓜品种形态指标的动态发育过程,以3个不同品种南瓜种苗为材料,系统地研究3个南瓜品种在苗床上的形态指标的动态变化规律,并对其形态指标进行比较和分析。结果表明:3个南瓜品种形态指标动态发育有明显差异,整体来讲种苗前期在株高、茎粗、地上部鲜质量干质量、地下部鲜质量干质量、叶面积等形态指标发育上红香栗占优势,但根长发育次于黄狼,蜜本的各项形态发育指标都比较低,种苗前期发育较迟缓。 In order to understand the dynamic development of morphological indexes of different pumpkin varieties, three different varieties of pumpkin seedlings were used as materials to systematically study the dynamic changes of the morphological indexes of three pumpkin varieties on the seedbed, and to compare and analyze their morphological indexes . The results showed that there were significant differences in the morphological characteristics of three pumpkin cultivars. In the whole, the morphological indexes of plant height, stem diameter, shoot fresh weight, shoot fresh weight, Xiangxiang dominated, but the growth of root length is inferior to that of the yellow wolf, the morphological indicators of honey are relatively low, early development of seedlings more sluggish.
