A method for rapid cultivation of small commercial pot plants of the genus Echeveria which is difficult to propagate by cuttings in a bottle

Abstract

The invention discloses a method for quickly cultivating small potted Echeveria plant goods difficult to cut and propagate on the basis of in-bottle molding. The small potted plant goods are obtained through two steps. The method includes step 1, inducing and cultivating high-quality molded rooting seedlings, and step 2, transplanting the molded rooting seedlings to pots for acclimation, and cultivating the small potted plant goods according to standards in later period. The step 1 includes selection and sterilization of explants, induction of regeneration bud seedlings, molding, proliferation and cultivation of the regeneration bud seedlings, secondary molding and rooting of strong seedlings. The method has the advantages that the technical problems of seeding propagation difficulty of the small potted Echeveria plant goods difficult to cut and propagate, low effective seed feeding rate, recombination or shape modification after single sprout potting, long operation cycle and the like are solved; effective seed feeding rate of tissue culture reaches more than 89%, duration is shortened by 90-100 days as compared with conventional methods, cost is reduced, and uniformity of potted plants for sale is high; particularly, the method has high economic benefit and practical utilization value in development of high-end famous Echeveria seedling products which are difficult to obtain through field cutting.

Description

technical field [0001] The invention discloses a method for quickly cultivating commercial small potted plants of the genus Echeveria that are difficult to propagate by cutting and propagating by plastic molding in a bottle, and belongs to the technical field of tissue culture rapid propagation and cultivation. Background technique [0002] Crassulaceae Echeveria is a perennial succulent ornamental herb, native to Pakistan, which can be cultivated in many places in the world. It has a beautiful appearance and rich colors. In the past two years, large-scale planting has developed rapidly. The rapid increase, the supply and marketing of commercial potted plants are booming. Especially since 2015, the demand for commercial potted plants of imported high-end varieties such as Echeveria 'Colorate Special', Echeveria 'Agavoides Red' and Echeveria 'Elegance' has increased rapidly, and the prices have remained high On the one hand, the market prospect and economic value are broad. ...
