Floral biology of Sesbania virgata: an invasive species in the Agreste of Paraíba, northeastern Brazil

Rodriguésia
Although reproduction seems to play an important role in the successful invasive strategy of Sesbania virgata, its floral biology is poorly known. We aimed at filling this gap by studying the floral biology of a population of S. virgata in the Agreste of

Limitations to the use of Apis mellifera (Hymenoptera: Apidae) for driven pollination of cultivars: a case study with European pear (Pyrus communis L. cv. Rocha)

Biotemas, 2015
The existence of pollinators able to promote xenogamy is a decisive factor in the yield of orchards. As it is allogamous, due to gametophytic self-incompatibility, most European pear cultivars do not produce fruits with seeds in the absence of ...
