The productivity of most of tropical and temperate perennial fruit crops, in particular the mango tree, is limited by irregular bearing. Studies on irregular bearing generally tackle the effects of fruit production in one year on flowering and fruiting in the following year, and do not consider vegetative growth between fruiting seasons. However, strong reciprocal relationships between vegetative and reproductive growth have been evidenced in some fruit speciès, suggesting they are involved in irregular bearing. Four mango cultivars with contrasted fruit bearing pattern were investigated, Cogshall, Kensington Pride, Irwin and José. We studied the relationships between vegetative growth and reproduction at the tree, scaffold branch and terminal growth unit scales. Vegetative growth was quantified at those scales by the number of new growth units set up du ring the vegetative growth season preceding flowering . Reproduction was assessed at those scales by the rate of flowering and the rate of fruiting. The relationships obtained were mostly cultivar-dependent and the following results are general trends. At the growth unit scale, we observed positive relationships between vegetative growth and flowering, but no relationship between vegetative growth and fruiting. At the scaffold branch scale, we observed few positive relationships between vegetative growth and flowering. At the tree scale, we observed negative relationships between vegetative growth and fruiting. Relationships between flowering and fruiting were weak or absent for the different scales and cultivars. The effects of vegetative growth on mango reproduction are discussed in light of these results. (Texte intégral)
