Abstract: 

IN ORDER TO INVESTIGATE THE SPECIES AND FUNCTIONAL DIVERSITY AND STRUCTURE OF WEED COMMUNITIES IN SUGAR BEET FIELDS OF DIFFERENT CITIES IN KHORASSAN RAZAVI AND KHORASSAN SHOMALI PROVINCES, IRAN, 178 FARMS FROM 12 CITIES WERE STUDIED. ABUNDANCE AND FREQUENCY, UNIFORMITY, MEAN FIELD DENSITY INDICES WERE STUDIED IN DIFFERENT CITIES. THE RESULTS SHOWED THAT WEED POPULATION IN DIFFERENT CITIES COMPOSED OF 56 SPECIES IN 14 PLANT FAMILIES, IN WHICH DICOTYLEDON SPECIES (44 SPECIES) WERE MORE THAN MONOCOTYLEDONS (12 SPECIES). THIS COMMUNITY, 47 SPECIES WERE C3 PLANTS (MONOCOTYLEDON & DICOTYLEDON) AND OTHERS WERE C4 SPECIES (MONOCOTYLEDON & DICOTYLEDON). THESE 56 SPECIES ALSO INCLUDED OF 36 ANNUALS, 2 BIENNIALS AND 18 PRENNIALS. POACEAE AND ASTERACEAE FAMILIES SHOWED THE MOST DIVERSITY AMONGST THE MONOCOTYLEDON AND DICOTYLEDON, RESPECTIVELY.
