摘　　要：对10个基因型不同的番茄品系幼苗进行了不同弱光环境下需光特性变化的研究。结果表明,随着光强的减弱,各番茄品系的光补偿点、光饱和点和最大光合速率均逐渐降低,而不同品系在不同光环境中表观量子效率的变化不同。The light requirement characteristics of 10 genotype tomato strains seedling were investigated under different low light density environments. The results showed that light compensation point, light saturation point and light saturated-Pn decreased gradually with reduced of light density, the change of apparent quantum yield were different among the tested strains under different low light density.
