Paclobutrazol Applied on Cotyledonal Leaves and Quality of Cucumber, Squash, Melon and Watermelon Seedlings

Abstract

The research was done to determine the effects of paclobutrazol (PBZ) through the dose of 150 mg∙L−1, on the quality of seedlings determined by the content of chlorophyll, height, leaf area, dry matter of roots and of the aerial part of cucumber, squash, melon and watermelon. Sowing of all species carried out on October 21, 2013 in polystyrene trays with 200 cavities filled with peat moss. Treatments were the doses of 150 mg of PBZ∙L−1 water and the control (distilled water). The solution with PBZ and the distilled water were applied only once with manual atomizer on cotyledonal leaves by mean of 25 shots made approximately with the same force, having put physical barriers between experimental units...
