Culture medium for bletilla striata tissue culture

Abstract

The invention provides a culture medium for bletilla striata tissue culture. The culture medium consists of improved MS culture medium: 1890mg / L to 1900mg / L of potassium nitrate, 1650mg / L to 1660mg / L of ammonium nitrate, 440mg / L to 445mg / L of CaCl2.2H2O, 370mg / L to 375mg / L of magnesium sulfate heptahydrate, 165mg / L to 170mg / L of monopotassium phosphate, 0.75mg / L to 0.83mg / L of KI, 0.025mg / L to 0.03mg / L of cobalt chloride, 27.8mg / L to 30mg / L of ferrous sulfate, 24.3mg / L to 26mg / L of ethylenediaminetetraacetic acid, 95mg / L to 100mg / L of inositol, 0.8mg / L to 1mg / L of niacin, 0.8mg / L to 1mg / L of pyridoxine hydrochloride, 0.8mg / L to 1mg / L of thiamine hydrochloride and 3mg / L to 4mg / L of glycine. Bletilla striata grown by the culture medium has the characteristics of strong roots, big corms, less variation phenomenon, high transplanting survival rate and fast growth.

Description

technical field [0001] The invention relates to the field of bletilla striata tissue culture, in particular to a culture medium for bletilla striata tissue culture. Background technique [0002] Bletilla striata is a perennial herbaceous bulbous plant with a plant height of 18-60 cm. It is mainly distributed in China, Japan and northern Myanmar. The main flowering period is in spring, but depending on the climate of each place, it may bloom from late winter to early summer. Bletilla striata has a wide range of medicinal value and garden value. Bletilla striata is mainly used to astringe and stop bleeding, reduce swelling and promote muscle growth. It can be used as a potted plant for indoor viewing, or as a decoration in a relatively shaded flower bed, flower border or corner of a courtyard. [0003] Utilizing tissue culture technology to quickly cultivate Bletilla striata seedlings is the most powerful means of artificially propagating Bletilla striata seedlings at present...
