Embodiment 1

[0021] 1. Obtaining and disinfection methods of explants: in the growing season, the lateral bud shoot tips of excellent strains of Strelitzia reginae 'Gold' which are vigorously grown and free from damage by diseases and insect pests are selected as explants. Because its explants grow underground, it is difficult to disinfect the endophytes. In this embodiment, 42 days before the disinfection treatment, water once with 800 times of liquid of 50% carbendazim wettable powder and spray the leaves, and then water once with 4000 times of liquid of 72% agricultural streptomycin soluble powder and spray the leaves after 7 days . Then after another 7 days, water once with 800 times of liquid of 50% carbendazim wettable powder and spray the leaves, and then water once with 4000 times of liquid of 72% agricultural streptomycin soluble powder and spray the leaves after 7 days. Then after another 7 days, water once with 800 times of liquid of 50% carbendazim wettable powder and spray th...

[0027] 1. Obtaining and disinfection methods of explants: in the growing season, the lateral bud shoot tips of excellent strains of Strelitzia reginae 'Gold' which are vigorously grown and free from damage by diseases and insect pests are selected as explants. Because its explants grow underground, it is difficult to disinfect the endophytes. In this embodiment, 42 days before the disinfection treatment, water once with 700 times of liquid of 50% carbendazim wettable powder and spray the leaves; after 7 days, water once with 3500 times of liquid of 72% agricultural streptomycin soluble powder and spray the leaves . Then after another 7 days, water once with 700 times of liquid of 50% carbendazim wettable powder and spray the leaves, and then water once with 3500 times of liquid of 72% agricultural streptomycin soluble powder and spray the leaves after 7 days. Then after another 7 days, water once and spray the blade with 700 times of liquid of 50% carbendazim wettable powder,...

Abstract

The invention discloses a rapid propagation method for high-quality seedlings of Strelitziareginae 'Gold'. According to the rapid propagation method for the high-quality seedlings of the Strelitziareginae 'Gold' provided by the invention, lateral bud stem tips of excellent strains of the Strelitziareginae 'Gold' are used as explants, and culture medium formulas and culture conditions suitable for all culture stages are selected through the stages of obtaining and disinfection of the explants, adventitious bud induction and subculture multiplication, rooting culture, test-tube plantlet transplanting and the like, so that the rapid propagation of the high-quality seedlings of the Strelitziareginae 'Gold' can be carried out in a short time so as to meet the requirements of the market. According to the rapid propagation method for the high-quality seedlings of the Strelitziareginae 'Gold' provided by the invention, the technology is simple, affordable, feasible and high in application value. The implementation of the method only needs simple plant tissue culture equipment to achieve.

Description

technical field [0001] The invention belongs to the technical field of plant tissue culture, and in particular relates to a method for rapid propagation of high-quality golden strelitzia orchids. Background technique [0002] Golden Strelitzia reginae (Strelitzia reginae 'Gold'), also known as the golden bird of paradise, belongs to the family Banana, and is a mutant strain discovered after large-scale propagation and cultivation of Strelitzia reginae using plant tissue culture. The flower color of this mutant is bright and golden, and it is of great ornamental value. It is suitable for planting in gardens, parks, among street trees and other public green spaces for greening, and can also be used as cut flowers and potted plants for ornamental purposes. The market price is high. Golden Strelitzia can be propagated by division, but the reproduction coefficient is low, and the number of breeding seedlings is very limited. [0003] At present, there is no report on the propaga...
