Abstract
The invention discloses a node order using method of medium-concentration IAA gel, and belongs to the field of plant biotechnology. The method comprises the steps of: first, compounding an IAA mother liquid of 1mg/mL; thendiluting the mother liquid to a medium-concentration IAA working liquid of 100mg/L; using the working liquid to compound a medium-concentration IAA gel sealing liquid, wherein the mass concentration of carboxymethyl cellulose sodium is 1%, and the mass concentration of sodium alginate is 8%; inserting branches into a cultivating substrate; and dropwise adding the gel sealing liquid to axillary buds of healthy and strong branches.
Description
Technical field
A joint position using method for middle concentration IAA gel, belongs to plant biotechnology field.
Background technology
Cottage propagation is one of vegetative common method of plant, especially trees, and the method has that cost is low, instant effect, cycle short, used branch abundance and can keep the plurality of advantages such as parent's merit.Usually can use dissimilar hormone during cottage propagation, as IAA, IBA, NAA, 2,4-D, GA
3, 6-BA, KT, TDZ, TIBA, ethrel, B
9, PP333, MH etc., the interpolation of above-mentioned hormone can enable plant at body or in vitro ahead of time or postpone to take root, bloom, bear fruit, and increases radical, induction axillary bud sprouting, improves percentage of fertile fruit etc., agricultural production plays important purposes.But the branch being difficult to break up in in-vitro propagate or rooting process, due to the loss of long moisture or nutriment, extremely easily causes death.And the method that existing employing urges root to lure bud to bloom possesses skills the shortcomings such as step is more, cost is high, unstable, in production, effect is unsatisfactory.Therefore, need badly a kind of fast and convenient method for plant axillary bud deriving, take root and Cheng Hua etc.
Summary of the invention
A joint position using method for middle concentration IAA gel, is characterized in that, include hormone mother liquor, working solution preparation, the preparation of hormone gel, cuttage, the dropping of axillalry bud place in described method, concrete operation step is as follows:
1. hormone mother liquor: precise weight be 0.1g IAA with a little 95% ethanol dissolve after, be settled to 100mL with distilled water, be the IAA mother liquor of 1mg/mL;
2. working solution preparation: it is concentration hormone working solution in 100mg/L that above-mentioned mother liquor is diluted to concentration according to the ratio of volume ratio 1:10;
3. hormone gel preparation: accurately take 1g sodium carboxymethylcellulose and 8g sodium alginate, dissolves for subsequent use with the hormone working solution that the concentration of 100mL is 100mg/L under 50 DEG C of water bath condition;
cuttage: branch is inserted in cultivation matrix;
axillalry bud place drips: drip gel confining liquid at the axillalry bud place of branch.
The invention has the advantages that from the viewpoint of water conservation, short root, lure bud, bloom, bear fruit, with hormone working solution for solvent, sodium carboxymethylcellulose and sodium alginate are gel carrier, are mixed with containing gel solution that is dissimilar, concentration hormone.Features such as during use, branch, flower being soaked in slightly above-mentioned solution or above-mentioned solution is dripped at axillalry bud place, film can be formed rapidly after gel drying, reaching the evaporation of minimizing moisture, being continuously applied hormone, be easy and simple to handle.
embodiment:
Below in conjunction with specific embodiment, the present invention is conducted further description.
