摘　　要：以角堇亮点播种苗为试材,研究秋冬季不同遮阴程度(100%NS、40%NS、20%NS和5%NS)对角堇幼苗的生长以及定植苗生长和开花的影响,以得出不同阶段最适合角堇幼苗生长及开花的适宜遮阴环境,为其植株盆栽生产提供科学依据。结果表明,在幼苗生长阶段,100%NS下角堇幼苗炼苗效果优于其他3个处理,其壮苗指数、叶绿素相对含量和干物质量显著高于其他3个处理;随着遮阴程度的增加,株高呈现先增加后减少的趋势;定植后角堇盛花期植株在40%NS下开花质量优于其他3个处理。To find out the best shade environment for Viola cornuta L.seedling growth and flowering in different stages and provide scientific basis for its potted production and application,the growth and flowering of Viola cornuta L.seedlings under different shade degrees(100%NS,40%NS,20%NS and 5%NS)in autumn and winter were studied with sowing seedlings of Liangdian Viola cornuta L.as experimental materials.The results showed that the seedling refining effect of Viola cornuta L.under 100%NS was better than that of the other three treatments,and its seedling index,relative content of chlorophyll and dry matter quality were significantly higher than those of the other three treatments.With the increase of shade degree,the plant height increased first and then decreased.And the quality of flowers blooming under 40%NS in flowering stage was better than that under the other three treatments.
