1.在 H 培养基附加动力精6—8毫克/升,2、4—D4—6毫克/升,萘乙酸2—4毫克/升的变动范围内,仅20天左右的时间诱导出了云南松胚状体,45天诱导出海岸松胚状体。2.通常萘乙酸,2、4—D 不同时使用,而本试验是在二者兼用的情况下产生的胚状体,同时经过重复,所用动力精与生长素水平高于一般用量。3.这一培养基再加修改有诱导出苗的希望,同时可以探索一次成苗的途径。4.胚状体的分化与胚乳组织颜色的变化密切相关,有待研究。 1. Induction of Yunnan in only 20 days with 6-8 mg / L, 2,4-D4-6 mg / L and 2-4 mg / L NAA in H medium Pine-like body, 45 days to induce the coast of pine embryoid body. 2. Usually naphthaleneacetic acid, 2,4-D are not used at the same time, and this test is in the case of the two embryos produced, while repeated, the use of progestin and auxin levels higher than the general dosage. 3. This medium plus modification to induce emergence of hope, but also to explore a way to become a seedling. The differentiation of embryoid body is closely related to the change of endosperm tissue color, which needs to be studied.
