Culture method of gloxinia double petal tissue

Abstract

The invention discloses a culture method for sinningia speciosa tissue, comprising the following steps: firstly culturing sinningia speciosa callus for induction; then culturing strong seedlings of sinningia speciosa to obtain robust plants; then performing rooting culture on regenerated buds of sinningia speciosa to obtain seedlings with roots; and finally performing seedling hardening and transplanting to obtain regenerated plants. According to the culture method disclosed by the invention, rapid propagation of sinningia speciosa can be realized, the survival rate is high, and the variety isexcellent, thus being suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for cultivating gloxinia double-petal tissue. Background technique [0002] Gloxinia, also known as sedumia, is native to the tropical grasslands of Brazil. It grows in warm and moist conditions, avoiding direct sunlight, and has a corresponding anti-heat level. It was originally developed by Jinling University and Zhongshan Botanical Garden in the United States around 1930. Introduced, after 1949, relevant botanical gardens successively tried planting, and put into small-scale production around 1990. Gloxinia belongs to Gesneriaceae, with a plant height of 20-30cm. It is a perennial evergreen bulbous flower. Its tubers are flat and spherical, and its leaves are oblong, opposite, thick and large. The whole plant is densely covered with white hairs. Long, it is an ideal flower for flower beds and indoor potted plants. [0003] Existing cultivation methods have...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the thick and strong pistils and small stamens of gloxinia, it is difficult to produce seeds, and the mature seeds are extremely small, about 28,000 grains / g, which are difficult to collect. Sowing requires high soil, and the offspring produced by sowing are prone to traits separation;

[0005] 2. The cutting propagation coefficient is low, it is difficult to reproduce rapidly, and cannot meet the requirements of mass production;

[0006] 3. Divided ball propagation has the disadvantage of irregular plant shape;

[0007] 4. Because it is a cross-pollinated plant, the offspring of the seeds will mutate, that is, the offspring propagated by seeds are difficult to maintain the original traits and the survival rate is not high
