2.Themilled ansfiltered potatoliquidbeing mixedwith 20% naturalfermentative sourliquor of pea, precipitation time of starch grains in it shortened by 6 times, extraction rate of starch was raised by 31 1% within30 minutes, whitenessdegreeof starch wasimprovedby 16 5%, andproportion of inferior starch reduced by 10 9% Morever the bacterial cell was with high agglutinating activity, which was prepared from the culture starch agglutinating bacteria through reasonable method, may be applied to starch extraction of potato as a better biological agent
4.When inadequate N was added, the chloroplast structure in mesophyll cell was damaged in ear leaf, the amount of carbohydrate decreased in mestome sheath , and excessive N-redistribution and N-transportation to grain from vegetative mass appeared, which resulted in earlier leaf senescence.Excessive N application led to too high activity of nitrate reductase, excessive vigorous nitrogen metabolism and too much exhaustion of carbohydrate in ear leaf, which resulted in the lack of enough carbohydrate in the lower leaf, meanwhile, the expansive chloroplast grana lamellae in leaf mesophyll cell and starch grain without nuclear in mestome sheath cell was observed, which led to the decrease of chlorophyll content and photosythetic capacity in maize leaf, then the early senescence occured.
5.The distribution of phenotypes of red cell phosphatase (ACP) in ten ethnic groups in Yunnan Province was investigated by starch gel electrophoresis. Three phenotypes A, AB and B were found. The gene frequencies of ACPA and ACPB in Han, Yi, Bai, Dai, Yao, Wa, Hani, Bulang, Jino and Lahu were 0.2067, 0.7933;
