Method for changing leaf color of aglaonema rosea tissue culture seedlings by utilizing illumination

Abstract

The invention discloses a method for changing the leaf color of a crassocephalum ramosissimum tissue culture seedling by utilizing illumination. The method comprises the following steps: culturing the tufted buds of the crassogyne lasioides in the proliferation, differentiation and rooting culture stages under the condition that the illumination intensity is 4000 lx or the light quality condition is that the ratio of red light to blue light is 3: 7, and controlling the illumination intensity and the light quality condition in the proliferation, differentiation and rooting culture stages of the tufted buds of the crassogyne lasioides, so that the red brilliant degree of the leaf color of the red-leaf crassogyne lasioides can be effectively kept; the method is beneficial to efficient and rapid large-scale propagation of high-quality aglaonema rosea seedlings.

Description

technical field [0001] The invention belongs to the field of plant seedling production, and in particular relates to a method for changing the leaf color of a tissue culture seedling of Rhododendron chinensis by utilizing light. Background technique [0002] Aglaonema spp. is a perennial herbaceous foliage plant of the genus Aglaonema in the family Araceae. Red-leaf Coleus is one of the more popular color-leaf varieties in China in recent years. It is widely used indoors as a small family potted plant. It is relatively shade-tolerant, has a long viewing period indoors, and can purify the air. And because the leaves have large red patches, thick ribs, and bright colors, which can fill the shortage of indoor and outdoor monotonous colors in the light-flowering season, it is deeply loved by consumers. . With the annual increase in the yield of red-leafed sturdy rib tissue-cultured seedlings, some red-leaf sturdy rib seedlings and finished potted flowers are prone to problems ...

AI Technical Summary

Problems solved by technology

With the increase in the yield of red-leaved Sclerosia tissue culture seedlings year by year, the seedlings and finished potted flowers of some red-leaved Sclerosia species are prone to problems such as leaf color fading from red to green, and the degree of redness of leaves is not strong, which is extremely unfavorable. Mass Production and Popularization of Red-leafed Grass Varieties

The main propagation methods of S. red-leaf are ramet propagation, cutting propagation and tissue culture rapid propagation, etc. The two traditional propagation methods of ramet propagation and cutting propagation are easy to be infected by germs due to improper wound treatment, and the propagation rate is correspondingly low; Tissue culture rapid propagation method has increasingly become the main way of supplying Sclerostidium seedlings, but for a long time, the leaf color and redness of Sclerosia seedlings bred by tissue culture and rapid propagation have always been stable to a large extent. It has become a limiting bottleneck for the propagation of rough rib seedlings and the promotion of industrial development
