| Abstract: | The relationship among carbon, nitrogen metabolism enzyme activities and quality of three varieties (K326. N C89 and Zhongyan 90 ) were studied during different development stages. The results indicated that K 326 appearead to have higher contents of total nitrogen and chlorophyll and greater activities of nitrate reductase and invertase than that of NC89. Zhongyan 90 at rosetle stage. After budding stage, Zhongyan 90 had higher nitrate reductase activity and lower invertase activity than K326 and NC89. The C/N of three varieties ware different at various stages. The C/N of Zhongyan 90 increased from rosette to budding,but that of K326, NC89 increased after budding stage. The order of harmony degree for carbon and nitrogen matebolism was: K326,N C89,zhong yan 90. |
