Abstract: -(Short storability of Caesalpinia echinata Lam. seeds as a consequence of oxidative processes). The seed bank is one of the strategies for the preservation of endangered species, such as Caesalpinia echinata Lam. In this work we studied the changes in O 2 consumption and CO 2 release by seeds incubated at different temperatures and water contents, evaluating the deterioration of seeds through germination and tetrazolium tests. Our results demonstrated that the deterioration processes occurring in C. echinata … Show more

“…Seeds stored at 22 °C, which initially possessed about 80% germination, were already dead in the first evaluation performed after six months of storage, thus confirming previous information about the low storability of C. echinata seeds under environments without temperature control (Barbedo et al, 2002;Lamarca and Barbedo, 2012).…”

“…However, these authors did not evaluate longer periods of storage as in the present study, in which it was demonstrated that positive temperature storage promoted complete loss of C. echinata seed viability within three years; these fi ndings invalidate any possible idea of preserving germplasm of this species at temperatures that are not negative. It reinforces, therefore, that negative temperatures are needed to reduce oxidative reactions that lead to rapid deterioration of C. echinata seeds (Lamarca and Barbedo, 2012).…”

“…As shown by Lamarca & Barbedo (2012) and Martini Neto et al (2014), the higher the temperature the more intense the deterioration of brazilwood seeds. There is also a strong correlation between brazilwood seed deterioration and the increase in the O 2 consumption without equivalent release of CO 2 .…”
