Interaction of Naphthaleneacetic acid and Kinetin in the Senescence of Detached Leaves 1

RESUMO
Kinetin and naphthaleneacetic acid were applied separately and in combination to excised leaf disks, localized areas of laminae, and petioles of detached leaves of broccoli (Brassica oleracea L., var. italica) and Xanthium (Xanthium pensylvanicum Wallr.). Senscence (measured as loss of chlorophyll) was strongly retarded by kinetin, but very slightly influenced by naphthaleneacetic acid. When the 2 substances were applied concurrently, the effect of kinetin was markedly reduced by naphthalene acetic acid. Neither interference with uptake nor transport of kinetin appeared to cause the reduction.
