摘要
应用粘土和蛭石粉作基质包埋铁皮石斛种胚来制作人工种子。试验结果表明 :当粘土∶蛭石粉∶MS培养液为 2∶1∶2时萌发率可达 5 6 .8%。在此系统中单独添加 1.0 %活性炭或同时添加 1.0 %活性炭和 0 .5 %淀粉制作的铁皮石斛人工种子 ,平均萌发率分别达 76 .7%和 80 .3% ,分别比对照提高了 18.4 %和 2 4 .2 %。
This paper describes the study on the Dendrobium candidum artificial seed prepared by using the clay and vermiculite powder as the encapsulating media.The results showed that the germination rate reached 56.8%, when the proportion of clay∶vermiculite∶water was 2∶1∶2. When this system was added with only 1.0% activated charcoal, or 1.0% activated charcoal and 0.5% starch, the corresponding average germination rates of the artificial seeds increased to 76.7% and 80.3% . The treatments enhanced the germination rate by 18.4% and 24.2% respectively, compared to the control. Both the effect of other seed coat materials used, such as chitosan, and the effect of protocorm like bodies' water loss rate on the rate of the artificial seed germination and storage were also studied.
