摘　　要：为了解外果皮去除与否对珍稀濒危植物堇叶紫金牛Ardisia violacea种子萌发及幼苗生长的影响,设置了去皮与未去皮2种处理4次重复的试验,研究了田间条件下堇叶紫金牛种子萌发与生长性状。结果表明:堇叶紫金牛未去皮种子的出苗时间推迟了19d,显著迟于去皮种子(P<0.05);未去皮种子出苗率为70.3%~75.6%,与去皮种子间没有显著性差异(P>0.05);堇叶紫金牛幼苗的生长表现为“慢-快-慢”的“S型”曲线,至生长结束时,株高、地径、叶长、叶宽分别介于5.32~5.34、0.12~0.13、4.40~4.96、2.08~2.12cm,叶片数量为13.4~14.8张,未去皮与去皮处理间差异不显著(P>0.05)。可见,果皮的存在对堇叶紫金牛萌发及幼苗生长没有显著影响,可以直接播种育苗。In order to understand the effect of exocarp removal on the seed germination and seedling growth of Ardisia violacea which was a rare and endangered plant,two treatments,peeled and unpeeled,were set up with four replicates to study the seed germination and growth traits of Ardisia violacea.The results showed that the emergence time of the unpeeled seeds of Ardisia violacea was delayed by 19 days,which was significantly later than that of the peeled seeds(P<0.05);The seed emergence rate was 70.3%-75.6%,and there was no significant difference between the unpeeled and peeled seeds(P>0.05);The growth of Ardisia violacea seedlings showed an″S-shaped″curve of″slow-fast-slow″.By the end of the growth,the plant height,ground diameter,leaf length and leaf width were respectively in the range of 5.32 to 5.34 cm,0.12 to 0.13 cm,4.40 to 4.96 cm,2.08 to 2.12 cm,and the number of leaves ranged from 13.4 to 14.8,so there was no significant difference between the unpeeled and peeled treatments(P>0.05).In conclusion,the existence of pericarp had no significant effect on the germination and seedling growth of Ardisia violacea,and the seedlings could be directly sown.
