The result of research is as follows:1.The incentive proportion of mulberry and hair white poplar, apple, willow, elm to Apriona germari is 6.8:1.2,5.6:1.2,5.8:1.2,6.2:0.8.Confirming mulberry incentive function to Apriona germari biggest.
The date indicated that the content of chlorophyll, chlorophyll a/b, netphotosynthetic rate, stomatal conductance and transpiration of every variety ofthe mulberry tree decreased with the water stress going on.
Two stilbene derivatives, oxyresveratrol and kuwanon Y, were isolated from the roots of Morus alba L. Oxyresveratrol and kuwanon Y had been shown to inhibit protein kinase C with IC50 values of 48 μmol · L-1 and 15 μmol · L-1 respectively.
桑树(Morus alba L.) 根的乙醇浸膏具有抑制蛋白激酶C(PKC)的活性,从中分得的二种二苯乙烯类衍生物:oxyresveratrol和kuwanon Y对PKC的半抑制浓度IC_(50)分别为48μmol·L~(-1)和15μmol·L~(-1)。
1. the results,which compared effect of phytohormone and antibiotic on the differentiation of adventitious buds in test-tube seedling of Morus alba, show that the concentration ratio of 6-BA to NAA from 20:1 to 30:1 promotes the differentiation of adventitious buds;
Sterols of Mulberry Leaves and Small Leaf Curl Disease
Free and bound sterols of leaves of five mulberry cultivars differing in their susceptibility to small leaf curl disease have been studied.
Three factors contributing to the increase of cocoon output are: the cocoon output per box, the area of mulberry field, and the egg amount raised per unit area of mulberry field.
The results showed that the importance of the factors in increasing cocoon output was in the order: egg amount raised per unit area of mulberry field >amp;gt; cocoon output per box >amp;gt; area of mulberry field.
