Abstract

Recently it was shown that boron mobility in the phloem of some species producing polyols are capable of B complex giving to this element some mobility within the plant. This research aimed to study the effect of fertilization with boron of peach seedling. The experiment was conducted in a greenhouse at UNESP, IlhaSolteira/SP. The experimental design was randomized blocks with three replications in a split plot, in two periods 30 and 60 days. It was studied five treatments in plots and two ages of leaves in the subplots old leaves and new leaves. The treatments studied were: no fertilizer with B in the soil and leaves; without fertilizer with B in the soil and leaves with 10B; fertilizing in the soil with B and leaves without B; fertilizing in the soil with B and leaves with 10B and fertilizing in the soil with 10B and leaves with B. It was evaluated the height, the number of leaves biweekly, B total content and the 10B percentage at the leaf from the fertilizer. Therefore, it can be conclude that boron fertilization on peach seedling provided an increase in the number of new leaves. The total content of B in the new leaves was higher in the boron fertilization in the soil to the leaf. There was boron mobility applied in the leaves in peach seedlings. (AU)
