本研究以铁皮石斛原球茎及丛生芽为实验材料,研究了香蕉汁和土豆汁2种有机添加物对铁皮石斛丛生芽的增殖和生长的影响。结果表明,土豆汁更有利于丛生苗的增殖,并以土豆汁25%处理的增殖效果最佳;香蕉汁处理的生根率、根数、根长都优于土豆汁处理,在培养65 d时3个香蕉汁处理的平均根长都达到0.65 cm以上,其中以添加香蕉汁25%处理的效果最好,其根长达0.84 cm;香蕉汁和土豆汁对铁皮石斛丛生苗的生长都有促进作用,在培养65 d时各处理的平均株高达到1.86 cm以上,且香蕉汁处理的平均株高均稍大于土豆汁处理,其中添加香蕉汁25%处理的株高达到2.1 cm。综合各实验结果,香蕉汁比土豆汁更有利于铁皮石斛的增殖和生长。

The effects of two organic additives (mashed potatoes, banana slurry) to MS on the multiplica- tion and growth of Dendrobium candidum are studied in this experiment in which Protocorms and its multiple shoots of dendrobium candidum are used as the materials. The results show that potato juice is more conducive to the clus- ters of seedlings multiplication and the result of mashed potatoes with 25% is the best. The rooting, root, root length of banana juice processing are better than that of potato juice processing; the average root length of three ba- nana juice processing is more than 0.65 cm after cultured 65 d; the average root length of banana juice processing with 25% is 0.84 cm which the result was best. Both the organic additives of banana juice and potato juice promote the growth of dendrobium candidum seedlings ; the average height of all treatments is more than 1186 cm after cul- tured 65 d; the average height of banana juice treatment is slightly larger than that of potato juice treatment, and the result of banana juice treatment with 25% is the best. From the experimental results, it is found that banana juice is more conducive to the multiplication and growth of Dendrobium candidum than potato juice.
