Developmengts anslysis on plant high, caulis leaves and single fruit showed with coincident disciplinarian, but distributing unlikeness. From seedling time to flourishing time, 2 importing varities's developments curve were keeping epigyny, showed that importing tomatoes varities had obvious advantage on plant high, caulis leaves and single fruit, and had bigger increase production potential.

株高、主茎叶片数和单株果数等3个测试指标的动态分析表明，规律一致但分布不同，2个进口品种的动态曲线从苗期到盛果期始终保持上位，说明进口品种在株高、主茎叶片数和单株果数3个生长发育指标上具有明显优势，植株生长旺盛，增产潜力大。

With an increase in the abundance and cover of Eupatorium adenophorum , there is a concurrent
