A preliminary examination of Cordyline plants indicated that this was a difficult material for investigating the influence of hormones on the cambial activity because (a) the plants do not form annual growth rings, making it difficult to measure the amount of new accumulation of the secondary tissue produced after the treatment of the meristem with growth regulators, (b) the growth rate of this plant is much slower than one of the dicotyledonous twigs and, therefore, the experiments with growth regulators take much longer and are more prone to the risk of tissue infection (Fisher & Tomlinson, 1972; Fisher, 1973).
