Embodiment 1

[0012] This example is to test the "National Day Yellow" chrysanthemum variety. The specific adjustment method is: take the young stem end from the field chrysanthemum plant as an explant, and carry out tissue culture. The culture medium is MS+6-BA 2mg / L+ NAA 0.1mg / L, culture room temperature 24-25°C, light 12h / d, illuminance 1500Lx; establish single-bud line material (use a single bud to propagate generation by generation); carry out 5-nitrogen on single-bud line material for 30 days Heterocytidine nucleoside treatment, the treatment concentration is 10uM, 1uM; the treated materials are rooted culture, the culture solution is: 1 / 2MS+NAA 0.1mg / L; finally transferred to the field cultivation management.

Embodiment 2

[0014] This example is an experiment on the "Mo Qilin" chrysanthemum variety. The specific adjustment method is: take the young stem end from the field chrysanthemum plant as an explant, and carry out tissue culture. The culture medium is MS+6-BA 2mg / L+ NAA 0.1mg / L, culture room temperature 24-25°C, light 13h / d, illuminance 1500Lx; establish single-bud line material (use a single bud to propagate generation by generation); carry out 5-nitrogen treatment on single-bud line material for 30 days Heterocytidine nucleoside treatment, the treatment concentration is 10uM, 1uM; the treated materials are rooted culture, the culture solution is: 1 / 2MS+NAA 0.1mg / L; finally transferred to the field cultivation management.

Abstract

The invention discloses a method for regulating and controlling chrysanthemum flowering season. More particularly, the method comprises the following steps: tender stem apexes are taken from field chrysanthemum plants as an explant; tissue culture is carried out, then a single bud material is established, that is, a certain single bud is reproduced in successive generations; the single bud material is treated by methylation inhibitor for 30 days, the treated material undergoes rooting culture and is finally transplanted to the field for cultivation management. The method of the invention adopts 5-azacytidine chemical treatment to change the epigenetic information of chrysanthemum in tissue culture, therefore, the chrysanthemum blooms 7-9 days in advance, and the effect can be passed on by vegetative propagation, and in the next year, the plants growing from the treated material roots can still bloom 7-9 days in advance.

Description

technical field [0001] The invention relates to a method for regulating the florescence of plants, in particular to a method for regulating the florescence of chrysanthemums. Background technique [0002] Chrysanthemum is one of the famous fresh-cut flowers in the current international flower market, and it is also the most widely cultivated popular potted flower. Chrysanthemum has been cultivated in my country for more than three thousand years. According to incomplete statistics, there are more than 7,000 kinds of chrysanthemums in the world at present. According to the natural flowering period, chrysanthemums are divided into spring chrysanthemums (flowering period from late April to late May); summer chrysanthemums (flowering period from late May to August); autumn chrysanthemums (flowering period from late October to late November); February of the year). Generally speaking, plant growth and development, flower bud differentiation and flowering are closely related to...
