Effect of ultrasonic treatment on the germination of spruce seeds



Effect of ultrasonic treatment on the germination of spruce seeds



Lesnoe Khozyaistvo (2): 36-37



Seeds of Picea abies were exposed to ultrasonic treatment in either water, a solution of thiamine, or a solution of nicotinic acid (vitamin B1). The ultrasonic treatment was provided by a vibrator (2 watts/cm2) fed from an ultrasonic generator (20 kHz); treatment times were 30, 60 and 120 s. The lengths of the germinating shoots 15 days after treatment are shown in a table.
