摘要:
以黑果龙葵为试材，研究了不同温度对其幼苗生长指标的影响。结果表明：在300 μmol·m-2·s-1的光照条件下，昼/夜温度30℃/25℃～25℃/20℃有利于龙葵幼苗的生长；相对较高（35℃/30℃）或较低的温度（20℃/15℃～15℃/10℃）极显著地抑制了幼苗株高、茎粗、叶面积的生长和地上、地下鲜重和干物质的积累；低温使龙葵幼苗叶片黄化、植株细弱。
Abstract:
Taking Solanum nigrum Linn as experiment materials，the influence of different temperature on the growth indexes of Solanum nigrum Linn seedlings were studied.The results showed that in the circumstances of a 300 μmol·m-2·s-1 light intensity，Day/night temperature between 30℃/25℃ to 25℃/20℃ was beneficial to the growth of seedling;a relatively higher temperature（35℃/30℃）or a relatively lower temperature（20℃/15℃ to 15℃/10℃） could inhibit the height，thickness of trunk and area of leaves and also inhibit the accumulation of weight of the above earth part and dry substances.Besides，at a lower temperature the leaves of seedlings would become yellow and the seedlings were thin.
