结果表明，品质性状的遗传主要由 基因加性效应引起，其中蔗汁锤度、旋光读数、转光度、蔗汁蔗糖分主要由父本 基因加性效应引起。
The results showed that the heredity of quality characters was induced mainly by additive gene effects. The changes in brix, PR, Pol and SC were affected by male parents.
方法：采用紫外分光光度法测定滴丸中维甲酸的含量，转篮法考察其体外溶出度。
Methods: Tretinoin in the dropping pills was determined spectrophotometrically and rotating basket method was adopted to determine its dissolution rate.
方法：采用溶剂-非溶剂法制备维生素C微囊，制成缓释片剂，采用紫外分光光度法测定其载药量，采用转篮法测定体外释放特性。
METHODS Use solvent-non-methods to prepare vitamin C sustained-release tablets, UV method was used to determine its content and the in vitro release rate was determined by rotate basket method.
