|
|
The study was carried out to investigate the effect of ethrel (2-chloroethylphosophonic acid, 39%) on the graftages quality. Ethrel was sprayed 5 days interval from October 10 to October 30 at 6 places (Suwon (I), (II), Chungju, Kongju, Wanju, Jangsong). Spraying conentration was 1,000 ppm (400 times dilution).
1. Spray took 3.3 hrs and 500 m of ethrel on 10a eara.
2. The passed rate of graftages decreased 5~8% on the treatments earlier spray than on Octorber 20.
3. New shoot length and number of shoot of the ethrel treatments were the same as the natural leaf falling.
