Abstract

The invention provides a culture medium for phalaenopsis amabilis tissue culture. The culture medium comprises the following components: 1900 mg/L of KNO3; 1650 mg/L of ammonium nitrate; 170 mg/L of potassium dihydrogen phosphate; 370 mg/L of magnesium sulfate heptahydrate; 440 mg/L of calcium chloride dihydrate; 0.60-0.62 mg/L of KI; 4.5-4.8 mg/L of boric acid; 25.0-25.3 mg/L of manganese sulfate tetrahydrate; 7.0-7.2 mg/L of zinc sulfate heptahydrate; 0.20-0.22 mg/L of sodium molybdate dihydrate; 0.025 mg/L of copper sulfate pentahydrate; 0.025 mg/L of cobalt chloride hexahydrate; 37.25 mg/L of Na2.EDTA; 27.85 mg/L of ferrous sulfate heptahydrate; 100 mg/L of inositol; 2 mg/L of glycine; 0.1 mg/L of thiamine hydrochloride; 0.5 mg/L of pyridoxine hydrochloride; 0.5 mg/L of nicotinic acid; 20-22 g/L of sucrose; 5-5.2 g/L of agar; 30-35 g/L of a banana juice; 3-5 g/L of a pear juice; 0.45-0.48 g/L of activated carbon; and a solvent being deionized water. With application of the culture medium to culture phalaenopsis amabilis, the survival rate is more than 96%, the bacteria infection rate is 2.7-2.8%, and the browning degree of the culture medium is 30-40% lower than that of an MS culture medium.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a phalaenopsis tissue culture medium. Background technique [0002] Phalaenopsis amabilis (Phalaenopsis amabilis), Orchidaceae (Orchidaceae) Phalaenopsis (Phalaenopsis) perennial epiphytic herb, known as the "Queen of Orchids", because its flower shape is like a butterfly flying, colorful , light and elegant body, very popular in domestic and foreign flower markets, has always been the darling of consumers. In addition to potted plants, Phalaenopsis is also particularly suitable for cut flowers, and is a high-grade flower material for artistic flower arrangements. [0003] At present, the common method of Phalaenopsis factory production is to use tissue culture for vegetative propagation, that is, so-called clonal propagation, which has the advantages of fast propagation, large quantity and pure seedling varieties. Using explants such as Phalaenopsis pedic...
