Rapid propagation method of potted gerbera jamesonii bolus tissue culture

Abstract

The invention discloses a rapid propagation method of potted gerbera jamesonii bolus tissue culture. The method comprises the following steps: shearing a gerbera jamesonii bolus receptacle into small blocks, sterilizing and placing in an MS culture medium containing 0.5mg / L of 6-BA and 0.1mg / L of NAA to induce, producing adventitious bud at an explant edge to acquire a sterile young plant, continuously placing blades of the sterile young plant in the culture medium as the explants, subculturing in the culture medium to obtain a robust plant, transferring the obtained robust plant into an MS rooting culture medium containing 0.3g / L of IBA to culture for 25-30 days to obtain a complete rooted plant, picking out an acquired rooted seedling from a culture bottle, cleaning and transplanting into a 72-cavity plate filled with matrix, gradually lowering relative air humidity to perform domestication and cultivation for 6 weeks, namely acquiring a transplanting stock. The young seedling obtained by use of the method disclosed by the invention is robust and high in survival rate, a great deal of high quality seedlings of the potted gerbera jamesonii bolus can be provided within short term, and the method has important effect on the scale promotion of the potted gerbera jamesonii bolus.

Description

technical field [0001] The invention relates to a rapid propagation method of potted gerbera through tissue culture, belonging to the field of agricultural science and technology. Background technique [0002] Gerbera jamesonii Bolus (Gerbera jamesonii Bolus), also known as gerbera and gerbera, is a perennial herb of the genus Gerbera in the family Asteraceae.
