摘　　要：为了解决华重楼的优质种源短缺的问题,以4年生以上的野生华重楼根茎为试验材料,开展根茎切块繁殖,观测种植后第3年地上部分的生长量和开花物候,研究野生华重楼植株之间的差异,观测结果表明:整个开花期的天数最少的45 d,最多的83 d,两者之间相差38 d,存在明显差异;优良植株高度和茎基直径大小的差距比最低的增加了118.42%、128.57%;植株结果率不足50%,果实的平均直径大小差距比最低的增加了68.55%;每颗果实的种子数量差距比最少的增加了1425%,而且3月22日以后开始开花,花期在55~64 d的植株高度和茎基径生长量最高。由此可见,开花期和地上部分的生长量植株之间存在着极大的差异。所以,不能直接将野生的华重楼根茎作为种苗培养采种母株,必须要通过人工筛选。In order to solve the problem of shortage of high-quality provenances of Paris polyphylla Smith var.chinensis(Franch.)Hara,the rhizomes of wild Paris polyphylla var.chinensis over 4 years old were used as the experimental materials,and the growth and flowering phenology of aboveground parts were observed in the third year after planting,and the differences between wild Paris polyphylla var.chinensis plants were studied.The observation results showed that:the minimum number of days in the whole flowering period was 45d,and the maximum number was 83d,resulting in significant differences.The difference between the height of the superior plants and the diameter of stem base increased by 118.42%and 128.57%,respectively,compared with that of the lowest plants.Plant fruiting rate was less than 50%,and the difference of average diameter of fruits was 68.55%higher than that of the lowest.The number of seeds was singular,and the difference of the number of seeds per fruit increased by 1425%compared with the least.In addition,it began to blossom after March 22nd,and plant height and stem basal diameter growth increased the most at the flowering stage of 55−64 d.It indicated that there was a great difference between flowering stage and aboveground plant growth..Therefore,the rhizomes of wild Paris polyphylla Smith var.chinensis(Franch.)Hara could not be directly used as the mother plant of seedling cultivation and seed collection,but must be artificially screened manually.
