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.
