THE MORPHOLOGY OF POLLEN GRAINS AS AN INDICATOR FOR IDENTIFICATION OF MALE PISTACHIO (PISTACIA VERA. L.) TREES
The results indicated the general shape of all examined pistachio pollen grains were circular to elliptical with 20 – 24 um in diameter. Pollen grains were polypantaporate and intectate (apparently pillate to clavate). The sculpturing feature showed different exine structures associated with different varieties. In this paper different aspects of pollen morphology are discussed.
