| 摘 要： | 为了揭示光质与种质对铁皮石斛种苗生长和有效成分的影响,采用8种光质(红光、蓝光、黄光、绿光和3个不同比例的红蓝混光),对3个家系(9×66,17×30,78×68)进行组培试验,测定农艺性状及叶绿素、总生物碱、多糖的含量.结果表明,光质和种质对铁皮石斛种苗和有效成分均有极显著的影响,红光有利于种苗根系与苗高生长,蓝光有利于种苗增粗与生物碱积累,红蓝混光有利于叶绿素与多糖含量增加.研究结果为铁皮石斛种苗优质、低碳、高效生产提供了基础,并为优质药材生产给出了有益的提示.

| Abstract: | Effects of light quality and germplasm on the growth and effective ingredients of Dendrobium officinale germchit were studied. Under 8 light qualities (red, blue, yellow, green and three different red blue mix light),test-tube plantlets of different families (9×66,17×30,78×68) were used in the experiment to measure economical character and determine the content of chlorophyll, polysaccharides and total alkaloids. The results showed that light quality, germplasm and their interaction had a significant effect on the growth of D. officinale germchit. The maximal root length and height of seedling were obtained under red light, under blue light, the stem diameter was thickest and the content of total alkaloids were highest, the content of chlorophyll and polysaccharides of test-tube plantlets under red blue mix light were higher than that of other treatments. This work has laid a foundation for the high quality, low carbon and efficient production of D.officinale, and gives useful tips on production of high quality ingredients. |
