Problems solved by technology

Among them, tissue culture technology requires high requirements, complicated operation, and high production cost; because Cotoneaster multiflora grows slowly, only 2 to 3 branches can be cut as cuttings according to conventional cutting propagation methods, and the propagation coefficient is very low; Seedling production enterprises and seedling farmers carry out large-scale breeding of Cotoneaster multiflora seedlings; using the totipotent regeneration function of plant organs, using Cotoneaster multiflora cotyledon bud cuttings, the reproduction coefficient is more than 5 times higher than that of branch cuttings, and the reproduction cost is low. Easy to operate; after literature search, there is no report in China

Abstract

The invention discloses a leaf bud cutting and seedling raising method of cotoneaster multiflorus. The leaf bud cutting and seedling raising method comprises the steps of preparing a cutting base material and a rooting agent, preparing shoots for cutting, treating the shoots for cutting, cutting and the like. The method disclosed by the invention is simple and convenient to operate and feasible, is low in cost and has simple technical requirements.

Description

technical field [0001] The invention relates to the technical field of plant asexual reproduction, in particular to a method for raising seedlings by cutting cotyledon multiflora cotyledon buds. Background technique [0002] Cotoneaster multiflora is a variety of Photinia in the family Rosaceae. It has many beautiful flowers and fruits. It should be planted in clusters on the edges of lawns and at the corners of garden roads. It is an excellent ornamental ground cover plant and has a broad market prospect for landscaping applications. [0003] Cotoneaster multiflora seedlings can be raised by tissue culture, cuttings and other vegetative propagation methods. Among them, the technical requirements of tissue culture are high, the operation is complicated, and the production cost is expensive; because Cotoneaster multiflora grows slowly, only 2 to 3 branches can be cut as cuttings according to the conventional cutting propagation method, and the reproduction coefficient is very...
