Description
The authors set cuttings of current year shoots of ca. eleven years old Akamatu on two sorts of bed, i.e. sand beds and Kibi soil-beds. They were ringbarked three weeks before and treated witlh six sorts of α-Naphthaleneacetic Acid solutions by the planting. Results obtained are as follows ;
1. rooting ratio was higher on a sand bed than on a Kibi soil-bed,
2. they couldn't find a remarkable difference in rooting ratio among cuttings treated by different dilution of α-Naphtaleneacetic Acid,
3. because they found vigorous roots on cuttings taken from certain trees and poor roots on the others. they suppose the rooting abilty were inherent in these trees.
