不同超级大南瓜品种生长动态研究

Growth Dynamic Research of Super Big Pumpkin Varieties

为了增加超级大南瓜的可塑性,研究超级大南瓜的生长规律,本项目通过对3个超级大南瓜品种的生长动态进行统计分析。结果显示:巨型南瓜表现为生长势强,瓜个体最大,瓜蔓最快生长期60-105d,纵横径的最快膨大时期均在生长第60-90d之间;3个南瓜品种在60-75d时,果实纵向生长速度快,横向生长慢,75d-105d则果实横向生长加快,纵向生长变缓,105d之后果实纵横向生长基本同速,这些时间段是超级大南瓜个体性状调控的关键时期,可以根据市场需求,在对应的生长期内对瓜的形状进行控制。

The growth dynamics of three super big pumpkin varieties was studied to reveal the role of super big pumpkin. The result shows: the giant pumpkin has stronger growth vigor, biggest size, the fastest growth period is 60-105 d, vertical and horizontal diameter are growing the fastest expansion period between 60-90 d. The fruit longitudinal growth speed of three pumpkin varieties in 60-75 d is fast, lateral growth is slow, the result is opposite in 75 – 105 d. The time of 60-75 d and 75 – 105 d is the key period to the super big pumpkin individual character control.
