Pollen morphology and total amount of protein in pollen extracts of introduced Lolium perenne L., Dactylis glomerata L., Festuca pratensis Hudson, Phleum pratense L., Avena sativa L. and Poa pratensis L. and Turkish species of Lolium multiflorum Lam., Lolium perenne L., Bothriochloa ischaemum (L.) Keng, Zea mays L., Avena barbata Pott ex Link, Dactylis gtomerata L., Hordeum murinum subsp. glaucum (Steudel) Tzvelev from the family Poaceae were compared. Pollens of the investigated Poaceae members were monoporate, spheroidal, protate spheroidal, and the ornamentation was granulate. It was observed that H. murinum subsp. glaucum (30.64%) had slightly higher protein than the other Turkish species examined. The percentages are 29.5 in L. perenne, 25.73% in Z. mays, 15.03% in B. ischaemum 7.16% in L. multiflorum, 5.42% in A. barbata and, 4.67% in D. glomerata. Total amount of proteins of Lolium perenne (8.1%) from home and abroad were low.
