초록

As for Ethephon treatment, the headingstage is 2 days later at the concentration of 250 ppm and500 ppm for the booting stage that when there is notreatment, 4 days later at the concentration of 1000 or moreppm but no difference for the blossoming and ripeningstage. The culm length get shorter as the concentration ofEthephon is higher and the rate of culm length damagedis 37% for 1500 ppm of booting stage, which is the mosteffective processing, and the inferior culm length damagerate is bigger than the superior culm length damage rate.
There is no difference between the number of glumousflower, culm and litter weight and the non-processing andas for the thousand grain weight, it is slightly bigger thanwhen there is not any processing. The rate of germinationis indifferent, the number of seeds get numerous regardlessof the concentration of treatment and the number augmentsby 5% maximum for the booting stage. The number ofdays it takes from treatment of desiccant to the moisturecontent for harvesting time is respectively 15 days forseeds of 30 day-treatment, 10 days for seeds of 35 daystreatmentand 5 days for seeds of 40 to 45 day-treatment.
As for the harvest time after treatment of desiccant, thetreatment at 30th days and 35th after the earing is 8 daysearlier than the culture by conventional methods, 8 daysearlier for the treatment at 40th day. When the desiccanttreatment is implemented, the thousand grain weight isheavier as the number of days of treatment gets later. Therate of germination gets higher as the number of days oftreatment after earing gets later but there is no statisticallysignificant difference 35 days after the earing. Yields are37% compared to the culture by conventional methods forthe treatment of 30 days after the earing, 70% comparedto the culture by conventional methods for the treatment of35 days after the earing, and 92% compared to the cultureby conventional methods for the treatment of 40 days afterthe earing. The treatment before the physiological maturityimpacts greatly upon the quality of seeds
