Quick propagation method suitable for scale production of high-quality seedlings of aronia melanocarpa

Abstract

The invention relates to a high-efficiency quick propagation method for scale production of aronia melanocarpa. The high-efficiency quick propagation method comprises the following steps of primary culture, differentiating culture, subculture culture, seedling sounding culture, rooting culture and domesticating transplanting, wherein a tissue culture seedling is directly differentiated into seedlings without a callus forming phase by adjusting the type and proportional ratio of the growth regulator in a differentiating culture medium, the differentiating coefficient is high, and the seedling grows strong; a rooting culture medium added with a certain amount of activated carbon is adopted, the dark environment is provided, and the metabolism harmful matters in the culture medium are absorbed, so that the root quickly grows, is strong and soft and is not liable to break, and the root is easy to survive in transplanting. The high-efficiency quick propagation method has the advantages thatthe culture cycle is shortened, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a rapid propagation method suitable for large-scale production of Aronia nigra, belonging to the field of agricultural biotechnology. Background technique [0002] Aroniamelanocarpa is a deciduous shrub of Rosaceae with edible, medicinal, garden and ecological value. Sorbus nigra has wide adaptability, strong cold resistance and drought resistance, and is suitable for planting in most regions of my country. The fruits of Sorbus adenocarpa contain anthocyanins (1%-2%), flavonoids (0.25%-0.35%), polyphenols (1%-2%), Vc (0.03%-0.06%) and β-hu Radish (0.005%) is the highest or higher content in known plants. Polyphenols are very important substances that improve the structure and function of capillaries and blood vessels, and also help stimulate and improve the circulatory system. Anthocyanins and flavonoids can keep the heart, urinary system healthy and improve immune system function. Vc and p-carotene have anti-aging function...

Problems solved by technology

[0005] At present, although there are a small number of reports on the tissue culture research of Aronia nigrita, the existing researches on the tissue culture and rapid propagation system of Aronia nigrum are basically small-scale propagation in the laboratory, and the production The cycle is long, and there is no report on large-scale open rapid cultivation of Sorbus arvensis seedlings, which brings inconvenience to the industrialized seedling cultivation of Sorbus arvensis
