MS medium with 0.1 mg·L -1 of BA and 0.1 mg·L -1 of NAA is suitable for the growth of shoots, and 2 3 adventitious buds were regenerated in base. But rooting rate reached only about 30% by using 1/2 MS with 0.25 mg·L -1 of NAA or with 0.25 mg·L -1 of NAA and 0.25 mg·L -1 of IBA.展开更多
前红松(Pinus prokoraiensis Zhao,Lu et Gu),松科松属单维束亚属植物,陆静梅等于1990年确立为松属中的一新种。前红松具有生长速度快、结实早、种子大,树型优美,且耐旱、耐盐碱等特点。前红松因种子发芽难且仅分布于吉林省土门岭一带...前红松(Pinus prokoraiensis Zhao,Lu et Gu),松科松属单维束亚属植物,陆静梅等于1990年确立为松属中的一新种。前红松具有生长速度快、结实早、种子大,树型优美,且耐旱、耐盐碱等特点。前红松因种子发芽难且仅分布于吉林省土门岭一带被列为濒危植物,因此对前红松进行速繁研究将有助于改善前红松的生存状况,还可使前红松充分发挥其生态及经济价值。展开更多
