Abstract
The study was conducted to investigate the effects of phosphorus fertilization on growth parameters, leaf mineralconcentration and
xylem and phloem mineral mobility ratio in two clonal prunus rootstocks grown in a greenhouse experiment. Trees of hybrid GF677
(Prunus persica × Prunus amygdalus;) and PollizoPuebla de Soto 101 (Prunus insititia; PP101) were grown in containers with 350
kg of a typical soil from SE Spain (Xeric torriorthen derived from marl). Phosphorous was applied to plants in the form ofmonoamonic phosphate in five different doses i.e 0.124, 0.248, 0.744, 2.976 and 14.88 g plant-1. Application of P fertilization in the
root medium significantly increased the trunk perimeter, totalleaf dry weight and total shoot length in GF677 trees but not in PP101
trees. The leaf P, K, Ca, Mg, N and Mn concentrations were also elevated in both rootstocks (GF677 and PP101). However, the leaf...
