REGULATION OF CHRYSANTHEMUM GROWTH USING GA3 AND ALAR TO OVERCOME SALINITY DEPRESSIONS
Watering with saline water at 5000 p.p.m. salts caused reductions 18.2% of plant height, 37.9% of plant fresh weight, 31.4% in root dry weight, 19.0% in inflorescence number/plant, 14.8% in peduncle length and 11% in infl. diameter.
Spraying of GA3 stimulated both growth and flowering, particularly at 100 ppm, it increased plant height 9.8%, plant fresh weight by 16%, root dry weight 8.6%, infl. number/plant by 7.5% and peduncle length by 10% of the control.
Alar spraying reduced plant height and unaffected flowering characteristics.
