Maturation of Eugenia pyriformis seeds under different hydric and thermal conditions Anais da ABC (AABC)
Lamarca,Edmir V.; Prataviera,Juliana S.; Borges,Igor F.; Delgado,Liliana F.; Teixeira,Carmen C.; Camargo,Marcelo B.P. de; Faria,José M.R.; Barbedo,Claudio J..
This study aims to analyze the maturation and dispersal of Eugenia pyriformis Cambess. seeds produced in different years, and the influence of variation in thermal and hydric environment on seed physical and physiological characteristics at dispersal. Fruits at different developmental stages were harvested in the city of São Paulo between 2003 and 2010, as well as in the cities of Campinas and Lavras, in 2009 and 2010 and analyzed for size and color. The seeds were extracted from the fruits and their dry mass, water content, germination and vigor were assessed. Results showed that seed maturation is unsynchronized to the maturation of the fruit, taking 45 days on average (430 growing degree-days), longer in rainy times or lower temperatures. Seeds with...

Physiological and cytological aspects of Inga vera subsp. affinis embryos during storage Braz. J. Plant Physiol.
Faria,José M.R.; Davide,Lisete C.; Silva,Edvaldo A. A. da; Davide,Antonio C.; Pereira,Roselaine C.; van Lammeren,André A.M.; Hilhorst,Henk W.M..
The remarkably short storability of recalcitrant seeds has prevented their inclusion in programs of ex situ conservation. The causes of their desiccation sensitivity and rapid decline in viability during storage are not fully elucidated yet. In this study the highly recalcitrant, fully viable embryos of the tree species Inga vera subsp. affinis were stored under various conditions and analyzed physiologically and cytologically at intervals, in order to obtain more insights in their loss of viability during storage. Embryos stored fully hydrated at 5ºC fully lost viability in 18 d. Sealed storage of partially dehydrated embryos slightly prolonged their viability, with 95% germination being attained after 14 d of storage. However, after 30 d of storage,...
