The mulberry juice contains high concentrations of α-glucosidase inhibitors that affect glycometabolism and cause diarrhea in animals, thereby affecting the de-velopment and application of mulberry (Morus alba L.) as feedstuff resources. ln this study, the effects of mulberry leaf extract with and without removal of mulberry juice on starch metabolism were analyzed and compared. The results showed that mul-berry leaf extract with removal of mulberry juice exhibited significantly lower inhibi-tion rate on starch metabolism compared with mulberry leaf extract without removal of mulberry juice. ln animal feeding trials, piglet feedstuff was added with 10% mul-berry leaf powder; compared with mulberry leaf powder without removal of mulberry juice, experimental piglets fed with mulberry leaf powder with removal of mulberry juice exhibited significantly improved weight gain and significantyl reduced diarrhea rate.
新疆的和田白桑(Morus alba L)较广东桑(Morus atropurpuroea Roxb.)具有更强的抗旱性,但以广东桑为砧木的和田白桑嫁接苗却未表现出耐旱的优势。相反,和田白桑扦插苗在水分胁迫下的叶片失水率明显低于嫁接苗,而相对电导率两者没有明显的差异。说明水分胁迫时砧木对植株地上部分失水率的影响显著。
