Crescimento e sobrevivência de mudas de cagaiteira (Eugenia dysenterica DC) nas condições de cerrado

Abstract

Many cerrado (tropical savannahs) fruits have potential for economic exploitation. The cagaita (Eugenia dysenterica DC) can be ingested in natura or like juices, ice cream, licor or jams. In this work, cagaita shoots from three tube-like plastic containers (50 cm 3 , 120 cm 3 and 228cm 3 ) and three rooting media types {soil + forest humus + vermiculite (1:1:2); soil + forest humus + vermiculite (1:1:2) + yoorin termophosphate 1g/l; and comercial Plantmax organic compound} were evaluated in the field for height and diameter growth and survival percentage. A randomized complete block design was used in a factorial model 3 x 3, with five replications and five plants per plot. All evaluations resulted in higher height and diameter growth for shoots from soil + forest humus + vermiculite rooting media, with or without chemical fertilization. The shoots obtained from different tube-like containers types and volumes showed survival rates between 76 and 100% at 540 days after transference to the field. Height and diameter growth were slow, reaching 46,267 cm and 0,637 cm at 540 days, respectively. This diameter can be considered suitable for grafting in this species.
