Four turfgrass seeds were used as materials in the experiment, which were Triplet, Fire Phoenix, Caddie, Gulf. KNO3、CaCl2、K2HP04 were used as initiator to treat the seeds. Each initiator set three concentrations:2%,4% and 8%.Soaking time is five min, moisture time is 12h,24h and 36h. The vigor of processed seeds were tested by seed growth determination、conductivity measurement、accelerated aging test、anti-cold determination and simulation of field emergence test. Then, select a suitable method of ini...
