Influência da temperatura e substrato na germinação de sementes de jabuticabeira (Myrciaria cauliflora Berg.)

Abstract

The experiment was developed in the Seeds Analysis Laboratory in the University of Espirito Santo, Alegre, Brazil. The objective was to study the effect of different temperatures and substrates on the germination and strength of Jaboticaba tree seeds. The substrates used were pure sand (A), soil + sand + cow dung (T+A+E), coconut rind powder (PC), Hortimix® (H); temperature treatments were 20°C, 30°C and alternation between these two temperatures. The experimental design was completely random, with four repetitions. The germination average, emergence rate, plant fresh weight and dry weight were compared using the Tukey's test at 5%. The temperature of 30° C and the soil + sand + cow dung (T+A+E) substrate in equal proportions was the most efficient combination of the conditions studied for the germination of this species.
