Controle do crescimento de mudas de morangueiro ‘Camarosa’ cultivadas em substrato comercial pela aplicação de proexadione cálcio
Abstract
O objetivo do trabalho foi avaliar o efeito do proexadione cálcio (ProCa) no controle do crescimento de mudas de morangueiro para produção em substrato comercial. O experimento foi realizado em casa de vegetação com mudas da cultivar Camarosa produzidas por enraizamento de estolões e mantidas em bandejas de 72 células. Os tratamentos consistiram de sete concentrações do regulador de crescimento vegetal ProCa (0, 25, 50, 100, 200, 400 e 800 mg L-1). Sendo realizadas avaliações de crescimento vegetativo e resposta fisiológica. O delineamento foi inteiramente casualizado com quatro repetições de 12 plantas. Observou-se que aplicações de doses de ProCa a partir de 200 mg L-1 (200, 400 e 800 mg L-1), reduzem o crescimento vegetativo, assim como, aumentam a concentração de clorofila e a atividade fotossintética de mudas de morangueiro ‘Camarosa’Downloads
