Description
Effect of internodes number and growth regulators on the growth and yield of M. piperita. L.The objective of this study was to evaluate the effect of internodes number and growth regulators on M. pepita. The experiment was conducted at The Research Institute for Spice and Medicinal Crops from July 21 to October 25, 1988. The experimental design was consisted of a randomized block design with two factors and three replications. The first factor was the number of internodes (1, 2 and 3 internodes) and the second factor was the growth regulators, 2.4-D (Hidrasil) 0.5 ml/l, nitroaromatic (Atonik) 1:2000, auxin + cytikinine (Sitozim) 2.5 ml/l and control. Research indicated that two internodes and 2,4-D or auxin + cytokinine tended to increase the shoot length, number of branches and dry weight of plant. There were no interaction between the number of internodes and growth regulators.
