Problems solved by technology

[0005] In order to solve the problem of trait degeneration of seedlings obtained by mainly using above-ground organs such as flower organs, leaves, and stem tips as gerbera explants in the prior art, the present invention proposes a method for rejuvenating and rejuvenating degenerated gerbera

Embodiment 1

[0023] Embodiment 1: Below in conjunction with example the technical scheme of the present invention is further described. The implementation time is from 2013 to 2014. The adventitious bud induction, plant regeneration and seedling hardening of gerbera were carried out in the tissue culture laboratory of the School of Forestry, Southwest Forestry University. The tissue culture seedlings were transplanted and seedlings were cultivated in Meilan flower seedlings It is carried out by a limited liability company, and the seedling planting and fresh-cut flower production are carried out at the gerbera planting base in Jinning County.

[0024](1) Obtaining the roots of degenerated gerbera: the aseptic bottle seedlings (variety name solar wind) propagated with gerbera filaments as explants by Kunming Meilan Flower Seedling Co., Ltd. as the original material, the material is After 3 years of subculture and breeding, the seedlings have shown degenerate traits, that is, the seedlings g...

Abstract

The invention relates to a method for rejuvenating degenerated plants and particularly relates to a method for rejuvenating degenerated gerbera jamesonii bolus. The method comprises the following steps: culturing the roots of the degenerated gerbera jamesonii bolus, wherein the roots of the degenerated gerbera jamesonii bolus serve as explants; selecting the lower sections of the roots of the degenerated gerbera jamesonii bolus, wherein the selected lower sections can be dedifferentiated to form callus, and the callus can grow into adventitious buds; inducing the adventitious buds, and performing enrichment culture to obtain rooted seedlings. By adopting the method, the seedlings can grow vigorously, the influence of continuous cropping soil to the growth and quality of the gerbera jamesonii bolus seedlings can be eliminated, the soil utilization efficiency can be improved, the character degenerated gerbera jamesonii bolus can be rejuvenated and reutilized, and money spent in purchasing high-quality gerbera jamesonii bolus seedlings of gerbera jamesonii bolus seedlings breeding companies can be saved.

Description

technical field [0001] The invention relates to a method for rejuvenating and rejuvenating decayed plants, in particular to a method for rejuvenating and rejuvenating degenerative gerbera. Background technique [0002] Gerbera ( Gerbera jamesonii Bolus), also known as gerbera, sun flower, etc., is a perennial hairy herbaceous perennial plant of the genus Gerbera in the family Asteraceae, native to Africa. Because of its huge flowers, tall and straight pedicels, rich flower colors, high rate of cut flowers, long life of flower arrangement, high ornamental value, and annual supply of fresh cut flowers under suitable conditions, it has become one of the top five cut flowers in the world. The genetic segregation phenomenon of gerbera in seed propagation is obvious, so that its excellent traits cannot be stably maintained between generations, and the multiplication coefficient of ramet propagation is low, which cannot meet the market demand for seedlings. The current commerc...
