摘　　要：野古草(Arundinella anomala)是一种优良的固沙植物和园林绿化观赏植物,文章以6个野生野古草种群为实验材料,通过种子萌发实验,测算出不同光照强度下各种群种子的发芽势(GP)、发芽率(G)、发芽指数(GI)、简化活力指数(PVI)与活力指数(VI)等指标,通过测算和对比指标来评定光照强度大小对野古草种子发芽情况的影响,为其资源的进一步开发利用提供实验基础。Arundinella anomala is an excellent sand-fixing plant and an ornamental plant in landscape gardening.This study used six wild populations of Arundinella anomala as experimental materials and conducted seed germination experiments to calculate the germination potential(GP),germination rate(G),germination index(GI),simplified vigor index(PVI),and vigor index(VI)of seeds under different light intensities.By measuring and comparing these indices,the study assessed the impact of light intensity on the germination of Arundinella anomala seeds,providing an experimental basis for further development and utilization of its resources.
