PERÍODO DE DORMÊNCIA DE SEMENTES DE IMBUZEIRO

Abstract

The objective of this work was to study the influence of the seeds storage period of the Imbu Tree (Spondias tuberosa Arruda) in the germination percentage and germination velocity index. The study was carried out from January to December 2004 in a greenhouse with 50% shadowing screen, under room temperature, at Embrapa Tropical Semi-Arid, Petrolina, Pernambuco State, Brazil, in a randomized complete block design, with six treatments and four replications. The treatments consisted of seeds harvested in six different crops. The germination percentage and germination velocity index were evaluated at 30, 60, 90 and 120 days after sowing through daily counts. The seeds of 2001 and 2002 crops had the best performance in terms of emergence and germination velocity index.
