摘　　要：以黑老虎[Kadsura coccinea （Lem.）A.C.Smith]种子苗为试材,研究了不同光照（100％光照、50％光照、30％光照、10％光照）对黑老虎生长及其叶片SPAD值的影响.结果表明,在100％（全光照）和10％光照下,黑老虎植株矮小,叶片数、叶片长度、宽度及长宽比和冠幅偏小,叶片SPAD值偏低;在30％光照和50％光照下,黑老虎植株高大,叶片数、叶片长度、宽度及长宽比和冠幅大,叶片SPAD值较高.黑老虎生长最适宜的光照范围是30％～50％光照.The effects of 100％,50％,30％ and 10％ light intensity on the growth and SPAD of K.coccinea [（Lem.）]A.C.Smith seedlings were studied.The results showed that dwarf plant,leaves number,leaves length,leaves width,proportion of the length and width,crown width and SPAD of K.coccinea [（Lem.）]A.C.Smith leaves were small under 100％ and 10％ light intensity.Tall plant,leaves number,leaves length,leaves width,proportion of the length and width,crown width and SPAD of K.coccinea （Lem.） A.C.Smith leaves were big under 50％ to 30％ light intensity.It is indicated that 50％ to 30％ light intensity is optimal for the growth of Kadsura coccinea （Lem.） A.C.Smith.
