PP333 is a foliar sprays growth retardants, it at a low concentration on strawberry vegetative growth significantly inhibited, it inhibits gibberellin biosynthesis inside plants. Strawberry cultivars, such as Belrubi cultivated in protected areas, were treated with different concentrations at the bud stage,
