Abstract

Phellogen activity in Robinia pseudacacia and some of the factors controlling it were investigated. A highly active phellogen is characterized by the production of large thin‐walled phellem cells. A layer of flat, thick‐walled phellem cells next to the phellogen characterizes an inactive meristem. The annual rhythm of phellogen activity of Robinia trees grown outdoors reveals that the phellogen is active twice a year, while under the same conditions the cambium is active once a year only. Under controlled conditions of temperature and day‐length the phellogen was found to be active mainly under combinations of short day and high temperature or long day and low temperature.
