组织培养是指把从自然环境中分离出来的一种植物组织,放入含有合成培养基的瓶中,于无菌条件下使之生长或发育成新植株的方法。近年来,国内外以植物组织培养为主要手段来发展林业的新技术发展迅速,诸如试管苗的繁殖,作物品种的改良,次生物质的大量生长和珍贵种质、种源的保存等,都已取得了巨大的进展。有些领域(工厂化育苗,花卉生产等)已形成了新的产业,且创造了可观的经济效益和形成了较完整的生物工程技术。组织培养在医学和生物学各个领域中也得到极为广泛的应用。林业生产存在着生产周期长,种子繁殖或扦插繁殖等特点。一些不易结实、扦插成活率低,或是珍稀优良树种的种质资源,传统的生产方式很 Tissue culture refers to the method of placing a plant tissue isolated from its natural environment in a bottle containing synthetic medium and growing or developing it under sterile conditions into new plants. In recent years, domestic and international plant tissue culture as the main means of development of forestry, the rapid development of new technologies, such as test tube seedlings breeding, crop varieties improved, the massive growth of secondary biomass and precious germplasm, provenance preservation, etc. Great progress has been made. In some areas (plant breeding, flower production, etc.) have formed a new industry, and has created considerable economic benefits and the formation of a more complete bio-engineering technology. Tissue culture has also gained a very wide range of applications in various fields of medicine and biology. There is a long production cycle of forestry production, seed propagation or cutting propagation characteristics. Some are not easy to sturdy, cutting survival rate is low, or rare and fine species of germplasm resources, the traditional mode of production is very
