滇重楼[Paris polyphylla var.yunnanensis(Fr.)Hand.-Muzz.]根茎的各部位切段都能繁殖出新植株。这些后代的四年生根茎,其增长速度比同龄实生苗快3—6倍。但切段间表现出较大的差异性:带顶芽切段能于种植的第一年成苗,并开花、结实,是根茎中生活力最强的部位,但其地上茎一般为单轴;中间和末端的切段,它们的出苗情况和有性繁殖相似,第一年只有极少数出苗,第二年才大量出土成苗,但不开花,地上茎出现较多的多轴现象。后代根茎和地上茎的主要成份与野生滇重楼基本相同。
New plants can be bred in all parts of rhizomes of Paris polyphylla var. Yunnanensis (Fr.) Hand.-Muzz. The four-year-old rhizome of these offspring grow 3-6 times faster than the same age seedlings. However, there was great difference between the cuttings: the cuttings with the top buds could be planted in the first year of planting, flowering and fruiting, and were the most viable parts of rhizomes, but the shoots were generally uniaxial; The middle and the end of the cut, their emergence and sexual reproduction similar to the first year only a very small number of emergence, the second year before a large number of unearthed into seedlings, but not flowering, shoots appear more multi-axis phenomenon. The main components of the descendants of rhizomes and aboveground stems are basically the same as the wild Yunnan relics.
