Description
Technical field
The invention belongs to breeding plant technical fields, specifically, be related to a kind of strawberry cuttage and seedling culture collect seedling method and
It is applied.
Background technology
Strawberry is rose family Fragaria herbaceos perennial, and the strawberry cultivated extensively in production belongs to octoploid pineapple grass
The certain kind of berries (Fragaria × ananassa Duch.), stolon is thin, internode length, upward at the second section position after stolon is sprouted
Shortening stem and leaf are grown, grows adventitious root downwards, the sub- seedling of stolon is formed, continues again at the axil of the sub- seedling of stolon newly formed
It sprouts stolon and forms the sub- seedling of next stage stolon, the sub- seedling of stolon can inherit the varietal character of female seedling completely, this is profit
The basic principle of strawberry seedling breeding is carried out with stolon.
Currently, the seedling in strawberry stolon source is mainly obtained in production by the method for keeping down the vines of a creeping plant and cuttage two ways.Pressure
Climing method：It with the elongation of stolon, keeps down the vines of a creeping plant at stolon even number section position and promotes sub- seedling rooting, do not cut between sub- seedlings at different levels
Stolon, sub- seedling can obtain nutrition by stolon from female seedling；But stolon is mutually wound, and operation labor intensity of keeping down the vines of a creeping plant is big,
Big boy's seedling mixes, and is unfavorable for cultivating high-quality strong sprout.Cuttage：Stolon growth period waits for every without operation of keeping down the vines of a creeping plant
When growing 3~4 sub- seedlings for having a small amount of adventitious root on stolon, sub- seedling both ends stolon is cut, by the sub- seedling of acquisition by big
Cuttage root-taking is concentrated after small classification, advantageously reduces labor intensity, improves seedling regularity；But since the seedling age of sub- seedling is different,
The blade of larger sub- seedling is excessive, the exposed overlong time of adventitious root and it is downright bad, and the blade and adventitious root compared with boy's seedling are very few,
It is unfavorable for surviving.
The Chinese patent application of Publication No. CN103975730A discloses a kind of cuttage and seedling culture method of strawberry, but it is only
