seed size
2.The agronomic characteristics of 66 mungbean germplasm resources selected from 4719 were evaluated in Shijiazhuang of Hebei, Weifang of Shandong and Zhengzhou, Henan provinces. These varieties have the traits of early maturity, big seed size, more pods per plant and high yield or with high protein, high starch, drought resistance, salt tolerance, resistance to Cercospora leaf spot,root rot and aphids.
8.The results showed as follows:Method a) , phase transformation temperature of α -Al_2O_3 would be lowed to 950℃ withaddition of 1wt% seed ( α -Al_2O_3 nano powder) and 3wt% AlF_3 or 1wt% ZnF_2 and with milling 3h, and grain size of 30nm and 33nm respectively would be obtained for lh heat preservation.
