This paper studied the effects of different shading(100%,51.2%,39.8%,18.9% and4.5% natural light)on the seed germination and seedling growth of Acanthopanax senticosus.The result showed that 100% natural light did not facilitate the germination of Acanthopanax senticosus seed,while shading accelerated the seed germination,difference of germination percentage between the shading groups was not significant.The seed germination coefficient was the highest at 39.8% nataral sunlight.The germination index was the...
