Rooting and seedling strengthening method for tissue culture seedling of gerbera jamesonii

Abstract

The invention discloses a rooting and seedling strengthening method for tissue culture seedlings of gerbera jamesonii. The rooting and seedling strengthening method comprises the following steps: cutting clustered tissue culture seedlings of gerbera jamesonii into single buds, performing lighting culture on a seedling strengthening rooting culture medium, inducing rooting, strengthening the seedlings in covered bottles for 1-3 months in a greenhouse or a culture room after rooting, gradually opening the bottles to strength the seedlings, and performing heel-in in a cultivation medium. By adopting the seedling strengthening rooting culture medium, sufficient nutrition can be provided, the growth speed of the tissue culture seedlings of gerbera jamesonii can be appropriately reduced, the maintenance and management time of the tissue culture seedlings of gerbera jamesonii on a seedbed can be shortened, production of the tissue culture seedlings of gerbera jamesonii is not interrupted in hot summer and cold winter, the labor and the water and power cost of seedbed management are greatly reduced, the method is simple to operate and convenient to manage, the tissue culture seedlings of gerbera jamesoni, which is cultured by using the method, are good in root system development, the survival rate after heel-in is greater than 99%, and the seedlings can all survive after being transplanted fixedly.

Description

technical field [0001] The invention belongs to the technical field of plant tissue culture, and in particular relates to a method for rooting and hardening gerbera tissue culture seedlings. Background technique [0002] Gerbera jamesonii (Gerbera jamesonii) is a perennial herbaceous plant of the genus Gerbera in the Compositae family. It has the advantages of rich flower colors, high flower yield, and long ornamental period. It is one of the top five cut flowers in the world and is widely used in potted plants and fresh cut flowers. [0003] With the continuous development of the flower market, the amount of seedlings used for gerbera production is increasing day by day, and the rapid propagation of gerbera seedlings using tissue culture technology has achieved rapid development. This technology can overcome the shortcomings of conventional means such as slow propagation of seedlings, affecting the promotion of new varieties, and the offspring of seedlings will mutate and c...

AI Technical Summary

Problems solved by technology

This technology can overcome the shortcomings of conventional means such as slow propagation of seedlings, affecting the promotion of new varieties, and the offspring of seedlings will mutate and cannot maintain the excellent characteristics of the mother plant.

[0004] Tissue culture technology is an important method for rapid propagation of gerbera seedlings. However, the artificial planting of tissue culture seedlings is a process from heterotrophic to autotrophic, and there are still problems of high management level requirements and low transplant survival rate. The most outstanding thing is that, affected by the season, when transplanting in summer and winter, the transplanting survival rate of gerbera tissue culture seedlings is greatly reduced

[0005] In order to overcome the defect of low survival rate of gerbera seedlings after transplanting caused by high temperature in summer or low temperature in winter, it is usually necessary to set the seedbed in a greenhouse, but the capacity of the seedbed is small, the operating cost is high, and the cultivation cost of a single seedling is greatly increased. When the equipment conditions are not good, the multiplication and rooting of the gerbera tissue culture seedlings will be stopped before the hot summer and cold winter, so as to avoid the fake planting of the tissue culture seedlings in the hot summer and cold winter, so the production will be stopped for about 3 to 4 months every year And, using the rooting and hardening methods of the existing gerbera tissue culture seedlings, excluding the influence of seasons, the survival rate of the fake planting of the gerbera tissue culture seedlings is about 90%
