Abstract
The invention relates to a breeding method of a new variety of banana, which comprises the five steps of sterile material acquisition, bud differentiation and proliferation, adventitious bud strong stock cultivation, rooting cultivation, and seedling adaptation and transplantation to obtain banana sprouts. Compared with the prior art, through a tissue culture technique, the breeding speed and the neatness of nursery stock can be greatly increased, the original female parent properties can be better maintained, the survival rate can be improved, thus, the output is increased, and the transplanting survival rate can reach 95%.
Description
Technical field
The present invention relates to a kind of herbal tissue culture method, especially relate to a kind of method of cultivation of new variety of banana.
Background technology
' Rowe Red ' plant is large-scale draft to banana, and is high about 1 meter, and red streak is arranged on the leaf, and sight is peculiar, belongs to small-sized plant in banana belongs to, and is to see the vegetable material that leaf is the master.Banana mainly in the torrid areas cultivation, is also paid attention at Temperate Region in China at present very much.As the Introduced Cultivars comparatively small amt of external introduction, its plant division is slow, but fixing market demand is arranged, and the huge market demand, and the seedling supply is restricted.By tissue culture technique, greatly improve the reguarity of reproduction speed and seedling, keep better original maternal character.' the group training report of Rowe Red ' there is not yet banana.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of reguarity that can greatly improve reproduction speed and seedling for the defective that overcomes above-mentioned prior art existence, keeps better the method for cultivation of a kind of new variety of banana of original maternal character.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of method of cultivation of new variety of banana is characterized in that, the method is acquisition, bud part Differentiation and proliferation, indefinite bud strong seedling culture, root culture and hardening and the transplanting five-step approach that comprises sterilizable material, and concrete steps are as follows:
(1) acquisition of sterilizable material: the budlet that takes the banana base portion, with behind the tap water flushing 2h on Bechtop, be the alcohol immersion 20-40s of 75wt% with concentration, the mercuric chloride solution of 1wt ‰ soaks 10-20min, behind aseptic water washing 5-6 time, blot surperficial moisture content with aseptic filter paper, get the budlet base portion and be cut into that 1cm is long to be inoculated on the inducing culture;
(2) Differentiation and proliferation of bud is: budlet was inoculated on the inducing culture after 3 weeks, the budlet base portion begins to expand, and the yellow-green colour projection occurs, visible significantly callus after 1 week, cultivated 1 month, and then downcut band bud callus and put into the adventitious bud proliferation substratum and cultivate;
(3) indefinite bud strong seedling culture
The Multiple Buds that in the adventitious bud proliferation substratum, induces, the Da Cong bud is divided into Xiao Cong or simple bud after, put on the strong seedling culture base, indefinite bud extends rapidly, can grow up to the plantlet of 2-3cm after 20 days;
(4) root culture
Get and highly be the plantlet of 2-3cm, switching enters root induction in the root media, and the seedling base section dissolves the former base of root of many whites after 10 days, can grow to 4-6cm after 30 days;
(5) hardening and transplanting
Root culture 20-30 days, when root system grows to 1-2cm, select the aseptic seedling of well developed root system robust growth, indoor uncork hardening 3 days is taken out afterwash root agar, and domestication after 40 days in the greenhouse can be transplanted outdoorly, gives rich water quality management and gets final product.
