Stylar trimorphism in four functionally andromonoecious Prosopis species (Mimosaceae)

The reproductive system of Prosopis chilensis, P. pugionata, P. flexuosa, and P. torquata is described. Observations were made of floral morphology, stigmatic receptivity, pollen grain viability, and the nature of pollen reserves. Scanning electrone microscopy and statistical analysis were carried o...

Observations were made of floral morphology, stigmatic receptivity, pollen grain viability, and the nature of pollen reserves. Scanning electrone microscopy and statistical analysis were carried out. The results allow us to conclude that: 1) The studied species have three distinct floral morphs characterized by significantly different style lengths and, to a lesser extent, different stamen lengths; 2) style precocity found in all species does not indicate protogyny; 3) flowers with shortest styles are not receptive; 4) the pollen grains of all floral morphs showed high viability; 5) peroxidase is present in both the pollen and pistil; 6) viable pollen grains invariably have both starch and pollenkitt; 7) the studied species are andromonoecious. © 1994 Springer-Verlag. 1994 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_03782697_v190_n3-4_p143_Hoc http://hdl.handle.net/20.500.12110/paper_03782697_v190_n3-4_p143_Hoc
