Abstract Dormant first-order axillary buds on kiwifruit
(Actinidia deliciosa (A. Chev) C.F. Liang et A.R. Ferguson) canes break
in spring and normally produce a single shoot bearing flowers through the
extension of the primary bud axis. Documented here is the occurrence of three
shoots arising from a single axillary bud, with each shoot bearing flowers,
after treatment with hydrogen cyanamide. Given that dormant first-order buds
contain second-order axillary buds, the multiple shoots reported here are
likely to be in part, the result of the extension of the second-order axillary
bud axes. This shows that the axillary meristems found within the second-order
buds also possess the inherent ability to produce flowers.
