| Abstract:
A three year study was conducted to evaluate the growth responses of paprika pepper (Capsicum annuum L.) to four different plant growth regulators (chlormequat chloride; chlormequat chloride + ethephon; mepiquat chloride; mepiquat chloride + ethephon). The regulators were applied as foliar sprays in the nursery at transplant time. A reduction in plant height was obtained with chlormequat chloride + ethephon and mepiquat chloride + ethephon. The same active ingredients promoted root weight and advanced flowering and fruiting. Total yield was not affected by any treatment. No effect on fruit quality was observed. | |
