Qualidade de diásporos de Myracrodruon urundeuva Fr. All. armazenados sob diferentes condições

Abstract: Termos para indexação: aroeira, condutividade elétrica, massa de mil diásporos, germinação, vigor. QUALITY OF Myracrodruon urundeuva Fr. All. DIASPORAS STORED UNDER DIFFERENT CONDITIONSABSTRACT -This work had to objective to evaluate the physiological quality of Myracrodruon urundeuva diasporas conditioned in different packs and stored under two conditions. The diasporas conditioned in a can and bags of polyethylene, of paper, and of mesh polyethylene were stored in chamber cooled by air conditioner and in roo… Show more

“…Guedes et al (2012) considered that the decline in the emergence speed was the first vigor alteration noticeable in diaspores of A. urundeuva stored for 240 days. The physiological quality of the diaspores stored under uncontrolled environmental conditions was lower, which corroborates with the findings of Caldeira and Perez (2008). This possibly happens because the average temperature over the 180 days of storage (32.2±2 °C) accelerated the metabolism and, consequently, intensified the respiration process.…”

“…In a natural environment, A. urundeuva diaspores quickly lose their viability and vigor after storage (Caldeira and Perez, 2008). This phenomenon happens because the diaspores are rich in lipids (Guedes et al, 2012), and it tends to be more intense in surroundings with high humidity (Mira et al, 2015).…”

“…In the natural environment, the seeds placed into paper and multiwall-paper packaging showed the lowest percentage of normal seedlings at the first count for germination, with a total loss of vigour in the twelfth month of storage (Figure 3). Caldeira and Perez (2008) found that diaspores kept in a room environment rapidly lost their initial viability and vigour after six months of storage. In the freezer, seeds kept in PETE bottles showed a reduction in vigour in the twelfth month, i.e.…”

“…Teófilo et al (2004) mencionaram que nas sementes de M. urundeuva acondicionadas em saco de papel sob condições ambientais há redução drástica da porcentagem de germinação ao longo do tempo de armazenamento, atingindo o porcentual de 0% a partir dos 9 meses. Caldeira & Perez (2008) constataram que os diásporos de M. urundeuva mantidos em ambiente de sala perderam rapidamente a viabilidade e o vigor iniciais, após seis meses de armazenamento.…”
