摘要
目的:比较研究霍山石斛的F1代与其亲本的生长量、有效成分和生理特性等差别,探讨霍山石斛杂交利用的可能性,筛选保持较高有效成分且产量高的新资源。方法:测定霍山石斛F1代与其亲本的生长量和有效成分,光合特性、内源激素含量和同工酶谱。结果:F1代的光合面积大、叶绿素含量高、chla/b比值低,净光合速度高, 生长量高于亲本米斛,接近亲本铜皮石斛,产量略高于2亲本;同时保持较高有效成分,有效成分高于亲本铜皮石斛,接近亲本米斛。F1代结合了2亲本的优点。结论:霍山石斛F1代的生理特性和产量、品质得到极大改善,可以通过种间杂交的方法对霍山石斛进行种质改良。
Objective: Through a comparison between F1 and its' parents on the growth, chemical components and physiology, this study aims to find the possibility of selecting new dendrobium hybrids with high yield and good quality. Method: To determinate the growth, chemical components, photosynthesis, hormones and isoenzyme in the plants. Result: Photosynthetic area, content of chlorophyll, net photosynthesis and yield of F1 generation are higher than those of the parents; chla/b rate is lower; growth is almost the same as in Dendrobium moniliforme; content of chemical components are the same as in D. huoshanense. F1 is approaching of advantages of parents. Conclusion: Physiological characters, yield and quality of F1 are greatly improved by hybridization.
