Studies on improving seed quality of Setaria sphacelata cv. Narok by sealing treatment

JIANG Long1,YIN Jun2,DENG Ju-fen2,ZHANG Mei-yan1,SUN Zhen-zhong1(1.Department of Prataculture Science,Yunnan Agriculture University,Kunming 650201,China;2.Yunnan Feedstuff and Forage Working Station,Kunming 650225,China)  
The experiment studied improving seed quality of Setaria sphacelata cv.Narok with different sealing treatments(0,2,4,6,8,10 d).The result indicated that the temperature and relative humidity of sealed seeds increased obviously.The temperature increased rapidly first,then reduced the speed,finally decreased gradually.The trend of relative humidity is similar to that of temperature,but it decreased rapidly in the middle stage.With the increase of sealing time,dehulling rate of sealed seed has increased by 14.04%-52.80% compared to the control.The germination rate of six days sealing treatment was the highest,which contributed to 64% and has increased 10% than the control.The sealing seed treatment could improve the seed quality of S.sphacelata cv.Narok effectively when the temperature was 24.77 ℃,the relative humidity was 93%,and the best time of sealing seed was six to eight days.
