摘　　要：以5个番茄品种为试验材料,研究弱光对番茄幼苗农艺性状的影响。结果表明:不同番茄品种幼苗在弱光条件下,植株增高,叶片宽度增加,弱光和正常光照条件下差异达到极显著水平,叶长在不同光照条件下差异不显著,不同品种间差异也不显著。其中,神宇红果对弱光耐性较强,未出现株高增高等现象。Five tomato varieties were used to study the influences of poor light on agronomic traits of tomato seedlings.The results showed the plant height of tomato seedlings in poor light was higher than that in normal light,and the leaf width of tomato seedlings was wider than that in normal light.The differences were extremely significant.But the difference of the leaf length of tomato seedlings in poor light or in normal light was no signifi-cant,and there were no significant differences among different varieties.The tolerant to low light of Shenyuhongguo was better,the plant height of which didn＇t heighten.
