Studies on the growth, chemical components and physiological characteristics of F1 generation of Dendrobium huoshanense / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHOD</b>To determinate the growth, chemical components, photosynthesis, hormones and isoenzyme in the plants.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>Physiological characters, yield and quality of F1 are greatly improved by hybridization.</p>
