通过对厚荚相思种子在不同温度及光照下发芽率、发芽势、发芽指数的测定，研究了温度与光照对厚荚相思种子萌发特性的影响。结果表明：温度对厚荚相思种子的发芽率和发芽指数的影响极显著，而对发芽势的影响不显著；光照周期对厚荚相思种子的发芽率、发芽势及发芽指数的影响均不显著；在25℃或者25/15℃的温度下催芽，厚荚相思种子的发芽率、发芽势及发芽指数均最高；光照对种子萌发无影响。

The germination rate,germination energy,germination index of Acacia crassicarpa were measured at dif-ferent temperature & illumination conditions.The effect of temperature & illumination on the germination charac-teristics of Acacia crassicarpa seed was studied.Result shows that:the temperature have significant effects on ger-mination rate & germination index of Acacia crassicarpa ;the effect of temperature on germination energy is not sig-nificant;the light period have insignificant effects on germination rate,germination energy and germination index of Acacia crassicarpa .At 25℃ or 25/1 5℃,Acacia crassicarpa seeds have higher germination rate ,germination ener-gy & germination index;the light has no effect on the seed germination.
