植物组织培养的优点： 1不受生长季节的限制 2不携带病毒 3培养周期短 4可用组培中的愈伤组织支取特殊的生化制品 5可短时间大量繁殖，用于拯救濒危植物 6可诱导之分化成需要的器官，如根和芽 7解决有些植物产种子少或无的难题， 8不存在变异，可保持原母本的一切遗传特征 9投资少，经济效益高 10繁殖方式多，试用品种多 缺点 （1）和常规营养体繁殖比生产成本高问题：在进行组培产业时通过选择高效益、名特优、珍稀等植物进行组培商品化生产，取得更高的经济效益。 （2）组培苗炼苗难、移栽成活率较低问题：现在通过培育健壮的组培苗、调控环境因素、选择适宜的基质，使组培苗移栽成活率达到90%以上。 |

Advantages of plant tissue culture: 1.It growswithout the restrictions of seasons 2 It Carries no virus 3 Its cycle culture is short 4 Callus in tissue culture can be used to gain special biochemical products 5 It can be used as largely breeding in a short period of time, to rescue endangered plants. 6 It can be induced to differentiate into organs needed, such as roots and buds. 7 The problem of the less or no seed production can be solved 8 There is no variation, which maintains the original female parent of all genetic characteristics 9 Investment is low and economic benefit is high 10 There are a lot of modes of reproduction and species trials Disadvantages: (1) Its production costs is higher than conventional vegetative propagation than high: in tissue culture industries, by selecting high benefit, 名特优, and rare plants, such as tissue culture commercial production, higher economic benefits can be achieved . (2) difficult seedling culture and low survival rate of transplant: through cultivating healthy tissue seedling, regulating and controling environmental factors, choosing suitable matrix ,the survival rate of transplant tissue reaches more than 90%. |
