Embodiment

[0017] This example is an experiment on the "Shenma" chrysanthemum variety. The specific adjustment method is: in the first ten days of February, use the budding strips at the base of the chrysanthemum cutting seedlings that grow robustly as explants, and tissue culture (the composition of the culture medium is: MS+0.1mg / L NAA+2 mg / L 6-BA) to establish single-bud line materials. The single-bud material was subcultured, and after 3 generations of subculture (subculture medium composition: MS+0.1mg / L NAA+1.0 mg / L 6-BA, pH 5.8), after subculture The chrysanthemum shoots were treated continuously for 30 days by adding curcumin with a final concentration of 100, 200 and 400 μmol / l to the subculture medium. After the treatment, they underwent conventional rooting and seedling hardening, and then moved to the field for normal cultivation and management. Ensure sufficient water and fertilizer throughout the life cycle, remove side branches, side buds, and redundant buds in time, and ...

Abstract

The invention relates to a method for promoting precocious flowering of chrysanthemum by utilizing curcumin. The method comprises the following steps: by taking germination strips at the roots of robust chrysanthemum cutting branches as explants, performing tissue culture to establish a single-bud strain material, carrying out subculture on the single-bud strain material, adding curcumin with final concentration of 100-400mu mol/l into the subculture medium after performing subculture for 2-3 generations, and continuously treating the chrysanthemum buds for 30-40 days, performing conventional rooting and seedling exercising after treatment, and transplanting in farmland and performing normal culture management. The method is simple to operate, obvious in effect (the blossoming time of chrysanthemum is 5-8 days earlier than before), the appreciation value of the chrysanthemum cannot be influenced, and the method is applicable to large-scale production.

Description

technical field [0001] The invention relates to a method for regulating the florescence of plants, in particular to a method for promoting early flowering of chrysanthemums by using curcumin. Background technique [0002] Chrysanthemum has a long history of cultivation in my country. Because of its various flower colors, different flower types and long flowering period, it is a flower variety with great economic value in the modern flower industry, and has a broad market and good prospects. At present, due to the prosperity of large-scale holiday activities in various places, the market urgently needs to cultivate early-flowering varieties of medium-flowering varieties and late-flowering varieties that bloom during the National Day. Therefore, as an important economic value of chrysanthemums, the flowering period requires people to break through the traditional control methods of temperature and light, and seek more economical, effective, convenient and practical control met...
