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.
When the mulberry seeds were stored at 3 ~ 12 ℃,the budding vitality and sprouting rate decreased by 1.5% ~ 2.8% and 4.2%~5.5% for two years storage,respectively,and were 53.25% and 68.75% for twelve years' storage,respectively.
In order to test the purity of mulberry seeds by means of gel electrophoresis of protein and quantitative analysis,four types of extracting solution of mulberry seeds by PO4,EX3,ddH2O and ethanol chlorine(20%,30%),respectively were screened.
Physical and chemic quality of mulberry seed oil, water 0.75%, density 0.9210, colour and luster Y25,R0.2, clarity, refraction exponential(n20)1.4744, acid value 0.75mg/g,peroxide value 4.06meq/kg,iodine value 130.35 g/100g.
The inhibition rates of extract from mulberry leaves at 2.3, 4.7, 7, 9.3 and 11.7 g/L on tyrosinase activity were 24.49%,38.22%, 51.95%, 74.83%, 79.41%respectively, and the concentration of kojic acid was 6.4 g/L when the inhibition rate was 50%.
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.
