EFEITO DA ÉPOCA DE PODA DO SISTEMA RADICULAR NO CRESCIMENTO DE MUDAS DE ALGAROBEIRA

Abstract

The aim of the present work was to evaluate the effect of different pruning time of Prosopis juliflora (Sw) DC root system on seedlings growth. The experiment was carried out in the nursery of ESAM, Mossoró-RN. The prunings were carried out at 30, 40, 50, 60 and 70 days after germination. The completely randomized block experimental design was used, with four replications and eight plants per plot. Evaluations for shoot height, stem diameter, shoot height/stem diameter ratio, shoot dry matter weight, total dry matter weight and roots percentage were done. Statistical difference was observed only for root percentages, and the best means were obtained for prunings carried out at 50, 60, and 70 days after germination.
