Environmental stress, future climate, and germination of Myracrodruon urundeuva...
Oliveira,Gilmara Moreira de; Silva,Fabricio Francisco Santos da; Araujo,Marcelo do Nascimento; Costa,Danielle Carolina Campos daAbstract: Myracrodruon urundeuva, a native species from the Brazilian Caatinga, is widely distributed across its endemic region, where it also plays an essential socioeconomic role. The objective of this study was to evaluate the influence of environmental stress on the germination of M. urundeuva seeds harvested in different years (2010 to 2013). Seeds were germinated at constant temperatures between 10 to 40 ...
Thermal stress and physiological changes in watermelon seeds
Silva,Rita de Cássia Barbosa da; Araujo,Marcelo do Nascimento; Ornellas,Fábio Luiz Santos; Dantas,Bárbara FrançaABSTRACT Given that watermelon is a crop widespread around the world, there is considerable interest in verifying how its seeds physiologically behave under unfavorable temperature conditions. This study aimed to evaluate the biochemical changes mobilization and reserves degradation, as well as the enzyme activity, during seed germination and initial growth of watermelon seedlings subjected to thermal stress, u...
Seed quality of Amburana cearensis (Allemão) A.C. Sm. (Fabaceae) is influenced ...
Araujo,Marcelo do Nascimento; Ferraz,Marisol; Américo,Fabiana Karla Araújo; Silva,Fabrício Francisco Santos; Dantas,Bárbara FrançaAbstract: The aim of this study was to evaluate the effects of storage conditions on the germination of A. cearensis seeds. The experimental design was completely randomized into split plots over time with four replicates. The storage conditions of the airtight containers in the refrigerator and laboratory, paper bags in the laboratory and liquid nitrogen were assessed for 27 months. In the laboratory, we evalu...
