“EVALUACIÓN DE DIFERENTES SUSTRATOS EN LA ACLIMATACIÓN EX VITRO DE PIÑA (Ananas comosus L. Merr) VAR PEROLERA”

Abstract

PINEAPPLE IS A TROPICAL FRUIT OF GLOBAL ECONOMIC IMPORTANCE, DUE TO THE FRAGRANCE, SWEETNESS OF ITS FRUIT AND CONSUMER ACCEPTANCE WORLDWIDE, BUT LACK OF SUITABLE PLANTING MATERIAL LIMITS ITS PRODUCTIVITY. A VARIETY OF MICROPROPAGATION PROTOCOLS HAVE BEEN DEVELOPED OVER THE YEARS TO ADDRESS THIS DEFICIENCY. EVEN SO, THE FINAL STAGE OF MICROPROPAGATION, I.E. ACCLIMATISATION, REMAINS A CHALLENGE AS PINEAPPLE SEEDLINGS GROW VERY SLOWLY, COUPLED WITH LOSSES IN THE ACCLIMATISATION STAGE WHICH ARE CRITICAL IN THE MICROPROPAGATION PROCESS. THEREFORE, THE AIM OF THIS RESEARCH WAS TO EVALUATE DIFFERENT SUBSTRATES IN THE EX VITRO ACCLIMATIZATION OF PINEAPPLE (ANANAS COMUSUS L. MERR) VITROPLANTS (ANANAS COMUSUS L. MERR) PEROLERA VARIETY. TWO TYPES OF EXPLANTS AND 10 TREATMENTS WERE EVALUATED IN FOUR REPLICATES EACH
