摘要: Performance of 'Forastero' (Prunus persica (L.) Batsch) peach grafted on six rootstocks (Brompton, Cuaresmillo, Ferdor® Julior, GF305, GF655/2 and Mr.S. 2/5) was evaluated in an experimental orchard charac- terized by a silty clay loam soil type. Significant rootstock-induced effects were noted for vegetative development (average leaf size, specific area, trunk cross-sectional canopy volume weight pruned wood), nutrient content (K, Mg, N, Ca P), fruit quality (diameter, weight, flesh, firmness color), total yield (TY), cumulative (CTY), efficiency expressed as per unit land area occupied the tree (YE), wood (PE), percentage photosyn- thetically active radiation (PAR) interception. Neither sucrose nor trunk-cross sectional affected rootstock, while PAR interception positively related to volume, average size Mg content. TY CTY both The that induced intermediate low growth, such Bromp- ton 2/5, had highest YE PE, suggesting these best scion perfor- mance studied orchard.
