摘 要: 对内蒙古地区有代表性的四个籽瓜品种植株 (地上部)的生长发育进行了研究 .结果表明 :内蒙古籽瓜的全生育期为92~101d,籽瓜植株的生长发育可分为发芽期、幼苗期、伸蔓期和结果期 ,结果期分为前期 (开花座果期 )、中期(果实膨大期)、后期 (种子成熟期 ) .发芽期、幼苗期以叶为生长中心 ,伸蔓期、结果前期以茎为生长中心 ,进入结果中期以果实为生长中心 .不同生育分期长短的差异主要表现在结果中期的差异上. The growth regularities of plant(overground part)in four typical seed-watermelon of inner Mongolia have been studied,respectively.The results showed that the total developing period of seed-watermelon of Inner Mongolia is92~101d.Plant growth and development are divided into four stages:germination stage,seedling stage,vine-extending stage,fruiting stage,and the fourth stage includes earlier stage(flowering and fruit setting stage),metaphase(fruit ex-panding stage),later stage(seed maturing stage).From germination stage and seedling stage to earlier stage of fruiting,the center of growth changes from leaves to stems,accordingly while in fruiting,fruits are the center.
