随着农业科学的迅速发展,从七十年代以来,有人不断地对各种植物,特别是名贵花卉,应用组织培养方法进行试管无性繁殖的研究。这种方法,有利于新育成的或新引进的珍贵品种的迅速繁殖和推广,同时还可避免病毒病的危害。 在石斛兰组织培养中,以茎尖、叶尖为外植体,在附加2,4—D 0.15—0.5毫克/升、BA 0.5毫克/升的MS培养基上,其分化率可达1:10左右。分化的幼芽转至含有活性
With the rapid development of agricultural science, since the 1970s, some people have continuously studied the asexual propagation of test tubes on various plants, especially the rare flowers, using tissue culture methods. This method is conducive to the rapid propagation and promotion of newly bred or newly introduced precious varieties, while avoiding the hazards of viral diseases. In the dendrobium tissue culture, the shoot tips and leaf tips were used as explants. The rate of differentiation was up to 1 in MS medium supplemented with 2,4-D 0.15-0.5 mg / L and BA 0.5 mg / L, 10 or so. Differentiated shoots turn to active
