“…Furthermore, seeds of many Brazilian tropical tree species in Myrtaceae family show high water content at shedding and have been considered to be sensitive to desiccation. However, among some species of this family, there are different desiccation sensitivity levels based on water content (Delgado and Barbedo, 2007;Masetto et al, 2008;Delgado and Barbedo, 2012). The seedlings development (length and dry matter) was better without seed drying (Table 2), thus, accessions Y52 e Y53 showed a mild sensitivity to dessication, although they do not show recalcitrant characteristics.…”

“…Water potential was measured in a WP4 potentiometer (Decagon Devices, Pullman, WA, USA), which was based on determination of the dew point temperature in equilibrium with the sample examined (Delgado and Barbedo, 2012). For this test, the seeds were cut lengthwise so as to speed hygroscopic equilibrium between the sample and the air and then immediately placed in plastic capsules, which were closed.…”

“…They are species that produce fleshy fruits that are suitable for fresh consumption or for industrialization and usually have few seeds (Delgado and Barbedo, 2007;Amador and Barbedo, 2011). These show a recalcitrant behavior, with different levels of tolerance to desiccation (Delgado and Barbedo, 2007;Delgado and Barbedo, 2012).…”
