Effect of Foliar application of CPPU, CCC on growth and flowering of Rose plant (Rosa hybrida L.)

Abstract

The study was conducted in the Lath house of the College of Agriculture / University of Kirkuk / Agricultural Research and Experiment Station, for the period from September 15/ 2021 to Until the end of April / 2022, The research included studying the effect of spraying with a growth regulator (CPPU) at concentrations of (0, 30, 60) mg L-1 with two sprays, the first one a day after the seedling rotation process, and the second one a week later, The first spray, And spraying with CCC growth regulator at concentrations of (0, 2000) mg.L-1, with two sprays, the first three days after spraying with CPPU, and the second two weeks after the first spraying, The factorial experiment was conducted according to the randomized complete block design (R.C.B.D), with a split experiment. The results were analyzed using the statistical software [1], Statistical analysis and Duncan's multiple range test were used to compare the means at the 5% probability level. The effect of spraying with the growth regulator CPPU at a concentration of 30 mg .L-1 led to a significant increase in the number of leaves, 167.66 leaves.plant-1 and the flower diameter was 13.91 cm, while the concentration of 60 mg.L-1 increased the vase life by 19.08 days. Spraying with growth regulator CCC at a concentration of 2000 mg.L-1 resulted in a significant increase in the number of leaves to 164.44 leaves.plant-1 and The number of flowers is 11.72 flowers.Plant-1.
