TAMANHO DE CLADÓDIOS NA PRODUÇÃO DE MUDAS DE PITAIA VERMELHA

Abstract

The cladodes size is an important feature when selecting cuttings for red pitaya (Hylocereus undatus (Haw.) Britton & Rose) seedling production. The paper was carried out with the aim of evaluating different sizes of cladodes in the production of dragon fruit seedlings. The experimental design was randomized blocks with five treatments, which were the cladodes sizes: 5; 10; 15; 20 and 25 cm, with four replicates and four cladodes per plot. After 80 days of the experiment, there were evaluated: number of shoots per plant, percentage of rooting, length of greater root and dry weight of roots. The size of cladodes directly influences the production of seedlings. The lengths of cladodes from 15 to 25 cm are the most suitable for the dragon fruit seedlings.
