Abstract: In order to explore the sprouting and growth habits of Polygonatum sibiricum rhizome, and to study the seedling cultivation technology of Polygonatum sibiricum, Polygonatum cyrtonema Hua was used as the experimental material. Seedling cultivation experiments were conducted by cutting 1-3 year old complete 1 segment rhizome and 3-year old 1 segment rhizome into different sizes of Tuberous rhizome to study the growth habits of cut rhizomes.The results showed that the new buds of the cut rhizome grow from the wrinkles on the epidermis of the rhizome, and they first sprout new buds, and then new roots grow at the base of the new buds, while mother rhizome does not grow new roots. The mother rhizome with buds begins to be unearthed in early April of the year of sowing, while those without buds can only be unearthed in the following year of sowing. The 1-3-year old Tuberous rhizome had no effect on germination rate and root length, but their impacted on plant height growth increases with the age of rhizomes. The germination rate, height growth, and root length of rhizome seed blocks all decrease with an increase in the number of cut blocks;Cutting a 3-year-old rhizome into 8 pieces can breed multi flowered Polygonatum seedlings, which can produce 4.43 times more seedlings than using uncut ones. The germination rate, height growth, root length had negative relation with the number of segments from rhizome increased. Seedlings cultivated by 8 segments from one section of rhizome was 4.43 times of that by one section. From this, it can be seen that Polygonatum cyrtonema Hua can choose to cut 3-year-old rhizomes into blocks for seedling breeding.
