Deterioração de sementes de Crotalaria juncea e suas conseqüências em laboratório e campo

Abstract: Sementes de Crotalaria juncea L. com conteúdos de umidade de 6,3 e 11,1%, foram armazenadas por 84 meses em condições ambientes e às temperaturas controladas de 20 e 30°C, e testadas periodicamente no laboratório quanto a germinação e vigor (índice de velocidade de germinação) e no campo quanto a emergência, altura da planta, produção de massa seca (massa vegetal na maturação) e de sementes. Até aos 30 meses, não se observaram diferenças significativas de germinação entre as sementes nas diversas condições, ap… Show more

“…The species offers nectar and pollen, having as main pollinators large bees (bumblebees) (Silva et al 2009). Also, has self-incompatibility system (Maeda et al 1986;Thimmaiah et al 2018), and owering period occurs from 60 to 120 days after planting (Salgado et al 1987) Our manuscript brings a new descriptive study about pollination and reproductive biology, highlighting the data about specialized behavior of pollinators to access oral reproductive structures and their in uence in the fruit and seed set. In addition, we reported the dimorphism of oral male structures in C. juncea (heterantry and heterostemony) through oral morphological studies, and also, we performed a pollinic study (quantitative and viability tests) comparing the different anther morphologies.…”
