【目的】研究适宜国家二级濒危珍稀植物对开蕨（Phyllitis scolopendrium）组培苗生长的光照条件,为其推广栽培提供技术指导。【方法】通过盆栽试验,在温度25~36℃,相对湿度55%~65%条件下,于温室内设置4种光照处理T1（CK）无遮光,T2遮光56%,T3遮光78%,T4遮光97%,对应光照强度分别为17 863~18 322,7 520~8 253,3 788~4 020,342~435lx。通过测定不同光照强度下3年生对开蕨组培苗的形态指标及光合色素含量、净光合速率日变化、光合-光照强度响应曲线和叶绿素荧光参数等指标,筛选适宜对开蕨组培苗生长发育的光照条件。【结果】经遮阴处理（除T4处理外）的对开蕨组培苗较对照组叶片变薄,比叶重降低,单叶面积增大,叶绿素含量增多。随光照强度减小,Pn日均值、L_（UE）、P_（max）、A_（QY）和ΦPSⅡ均表现出先增后降的变化趋势,并在T2处理下达到最大,T4处理最小;Chl a/b、L_（CP）、L_（SP）、R_d、Fv/Fm、Fv/Fo、Fv′/Fm′、qP及NPQ均呈下降趋势。T1处理的Pn日变化呈＂双峰＂曲线,T2、T3、T4处理呈＂单峰＂曲线。【结论】4组处理中以T2处理的植株生长状态最好,故认为对开蕨组培苗生长的最适光照强度是7 520~8 253lx。
