Abstract
This paper describes the effects of 6-benzylaminopurine (6BAP) on bud sprouting in mature Aralia elata Seem. trees. Greater bud sprouting was induced on cuttings from the upper parts than lower parts of the tree, with 50 mg/l if 6BAP than without. An average of 1.4 buds sprouted on the stumps not sprayed with 6-BAP after the trunks had been removed for the collection of cuttings. However, 3.4 buds sprouted on stumps receiving three applications at this concentration. From 2.9 to 3.5 buds sprouted when 50–200 mg/l of 6BAP was sprayed onto trunks of three to four-year-old plants whose apical buds were removed, and 1.8 on trunks not sprayed with 6BAP. © Pesticide Science Society of Japan
