Abstract

A comparative scanning electron microscopy study and biometric analysis of pollen of 14 Spanish Vitis vinifera L. subsp. sylvestris (Gmelin) Hegi populations was performed. In all the investigated populations pollen grains show a marked degree of dimorphism. Pollen grains from male flowers are prolate spheroidal and tricolporate in shape, while the pollen grains from female flowers are spheroidal to oval, unaperturate, with no colpi.
