Abstract

The invention provides a method for separating and breeding pure-color dendrobium flowers. The method comprises the following steps that lateral bud stems of dendrobium are taken as explants, a protocorm induction culture medium is prepared from 3mg / L of 1 / 2MS+BA and 0.2 mg / L of NAA, a protocorm proliferation culture medium is prepared from 3mg / L of 1 / 2MS+BA, 0.2 mg / L of NAA, 30g / L of bananas and 20g / L of potatoes, and by combining liquid suspension culture and a treatment mode of cutting off new buds to separate and breed the pure-color dendrobium flowers. According to the method for separating and breeding the pure-color dendrobium flowers, the protocorm proliferation rate can be improved, stable pure color flowers are effectively separated from the dendrobium nobile flower color chimera, and the separation rate reaches 76.09%.

Description

technical field [0001] The invention relates to the technical field of separation and breeding, in particular to a method for separation and breeding of solid-colored dendrobium orchid flowers. Background technique [0002] Dendrobium orchid, Dendrobium orchidaceae is a perennial herbaceous epiphytic plant, with huge racemes, various flower colors, and gorgeous and colorful. Dendrobium has many flower color chimeras, such as red and white flower color chimeras. The flower color and pattern of such flower color chimeras are unstable during reproduction, and it is difficult to keep consistent with the mother plant. And pure color flower or single color flower varieties can maintain the stability of flower color in the breeding process, and have higher commerciality. [0003] Dendrobium orchid conventional propagation methods are branching, branching and cuttings, but these methods have larger propagules and low reproductive rates. Dendrobium orchid can be rapidly propagated ...
