Description
Technical field
The present invention relates to the method for a kind of quick breeding citrange, especially relating to a kind of is explant and continuous shoot proliferation cultured method with the grafting plant.
Background technology
Citrange [C.sinensis (L.) Osb * Poncirus trifoliate (L.) Rsf.] is the hybrid of sweet orange and trifoliate orange, it is the stock of each oranges and tangerines producing country extensive use of the world, growth potential is stronger than Fructus Aurantii, inherited the characteristic of Fructus Aurantii anti-foot rot, anti-decline disease, and have drought-enduring, cold-resistant, an impoverishment tolerant, wide to soil suitability, with features such as most of commercial breed affinity are strong.
In the quick proliferation of oranges and tangerines cultured in vitro, majority utilizes seedling plumular axis, cotyledon to cultivate at present, instrument has minority to pick up from the grafting tree stem apex or the stem section is an explant, and this mainly is because the differentiation of bud is of poor quality, coefficient of differentiation is low, be easy to generate callus in the incubation, particularly in the enrichment culture process of bud, produce callus Cheng Miao, often produce character variation, breeding kind problem of unstable occurs, do not reach the specification requirement that the oranges and tangerines nursery stock is bred in batch production.
Summary of the invention
The object of the present invention is to provide a kind of differentiation quality of bud good, the coefficient of differentiation height, what the breeding kind was stable is the citrange quick breeding method for tissue culture that explant and continuous shoot proliferation are cultivated with the grafting plant.
The objective of the invention is to be achieved through the following technical solutions.
It comprises the steps: that it is MS+BA 0.5～1.5mgL that inducing of (1) grafting plant stem-segment with node explant bud sprouted the inducing culture based formulas
-1(preferred version is MS+BA 1mgL
-1); (2) proliferation and subculture of bud is cultivated and is used medium MS+BA 0.2～1mgL
-1+ NAA0.01～0.1mgL
-1(preferred version is MS+BA 0.5mgL
-1+ NAA 0.05mgL
-1) shoot proliferation cultivation continuously; (3) culture of rootage and transplanting are with 1/2MS+NAA 0.2～0.8mgL
-1(preferred version is 1/2MS+NAA 0.5 mgL to+0.2% active carbon
-1+ 0.2% active carbon) medium is induced propagation blastogenesis root, 24 ± 2 ℃ of cultivation temperature, and continuous illumination every day 10-14 hour, intensity of illumination is 1000～1500lx; Cultivate after 20～35 days, take out test-tube seedling transplanting, the transplanting medium prescription is a white sand soil: the peat composed of rotten mosses=1: 0.8～1.2 or white sand soil: fermentation cotton seed hulls=1: 0.8-1.2 (preferred version is a white sand soil: the peat composed of rotten mosses or fermentation cotton seed hulls=and 1: 1).
Advantage of the present invention is: citrange grafting tree stem explants induced bud quality is good, and bud can be in proliferated culture medium continuous multi-generation propagation, and regeneration plant does not have variation, and reproduction coefficient can reach more than 3, reaches the specification requirement that the oranges and tangerines nursery stock is bred in batch production.
