Substratos e níveis de água no potencial germinativo de sementes de uvaia

Abstract

The objective of this study was to evaluate the substrate and water availability on germinative pontential of Uvaia (Eugenia pyriformis) seeds. The substrates evaluated were the following: Sand (S), Latosol + sand (L + S) (1:1), Latosol + sand + semi-decomposed chicken litter (L + S1+ CL) (1:1:0.5), Latosol + sand + semi-decomposed chicken litter (L + S2 + CL) (1:2:0.5), Latosol + Bioplant ® + (L + B) (1:1) joined to the following water levels: 25, 50, 75 and 100% the ability to retain water. The highest percentage of emergence and the best seedling growth were observed in substrates Latosol + sand + chicken litter (1:2:0.5) and water retention capacity of 50%.
