Desenvolvimento de mudas de Araçá (Psidium sp.) cultivada em diferentes substratos e recipientes

Abstract

Psidium sp. it is a fruit species native to Brazil that has not yet been studied and has great economic, food, environmental and pharmaceutical potential. In this way, this study aimed at araçá seedlings developed in different substrates and containers. The seedlings were grown in a greenhouse. The substrates adopted in the study were: commercial Plantmax ® (S1); mixture of ravine soil, vermiculite and fine sand (S2) in a 2: 1: 1 ratio; mixture of ravine soil and fine sand (S3) in a 2: 1 ratio; mixture of ravine soil, rice straw and fine sand (S4) in a 2: 1: 1 ratio. The containers used were: black colored polyethylene bags of 15 cm in diameter x 25 cm in height (R1) with a capacity of 4,415 cm³; black colored polyethylene bags 7 cm in diameter x 15 cm high (R2) and capacity for 576 cm³; and plastic cup (R3) with a capacity of 250 cm³. As a 4 x 3 double factorial scheme, the Fisher Test was used to compare the means and the data were submitted to the robustness test. Araça can be grown in different substrates and containers in the first year of seedling cultivation.
