Abstract
At greenhouse of National Research Centre, Dokki, Giza, Egypt. A pot experiment was carried out to evaluate the effect of Kinetin spraying on growth and chemical constituents of cordyline plants. The present study shows a considerable difference in the growth parameters when treated with kinetin concentrations of 0, 100, 150 and 200 ppm compared with the control plants. It was found that, increasing levels of kinetin from zero to 200 ppm increased plant height, root length, stem diameter as well as leaves number, anthocyanin pigments and K%. On the other hand, application 200 ppm recorded decreased in nitrogen and phosphor percentage compared with the control. While application of 100 ppm kinetin significantly increased chlorophyll and protein content compared with the control plants.
