Biologia floral e polinização por abelhas em siratro (Macroptilium atropurpureum Urb.)
Acta Scientiarum: Animal Sciences, 2008 Cette recherche a été réalisée pour évaluer la pollinisation chez le siratro en étudiant la période d'anthèse, la viabilité des grains de pollen et la production de graines. Deux traitements ont été utilisés, l'un couvert et l'autre découvert. La période d'anthèse était de 2,48 jours et de 3,56 jours (p = 0,0001) et la production était de 8,62 et 11,15

New Phytologist, EarlyView.The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.
