| چکیده | ||
| بررسی از علف های هرز زمین های چمن در دانشکده کشاورزی، دانشگاه شیراز در باجگاه در دو سال متوالی 1388-1387 انجام شد. در زمین های چمن با چمن اسپورت پوشش یافته، نمونه گیری از هر زمین صورت گرفت. اندازه گیری های کمی مانند فراوانی (F)، یکنواختی زمین (FU)، میانگین تراکم زمین (MFD)، میانگین وقوع تراکم زمین (MOFD) و فراوانی نسبی (RA) ثبت شدند. چهارده گونه علف هرز متعلق به 9 تیره گیاهی ثبت گردید. اکثر آن ها شامل: مینا سانان، باقلا سانان، فریژسانان و بارهنگ سانان می باشند. مهم‌ترین علف های هرز پهن برگ و باریک برگ، به ترتیب گل قاصد و چایر می باشند. نتایج نشان داد که بیشترین فراوانی (F) (100%)، یکنواختی زمین (FU))28/89%)، میانگین تراکم زمین ((MFD ( m-243/58%) ومیانگین وقوع تراکم زمین) (MOFD (m-243/58%) متعلق به گل قاصد در سال 1387 می باشد. نتایج سال 1388 تقریباً مشابه سال 1387 بود. گل قاصد بالاترین فراوانی نسبی را در هر دو سال نشان داد. | ||

| چکیده [English] | ||
| A weed survey of turfgrass fields was conducted at Bajgah during 2008- 2009. The turfgrass fields had been covered with Sport turf. Quantitative measurements viz frequency (F), field uniformity (FU), mean field density (MFD), mean occurrence field density (MOFD) and relative abundance (RA) were recorded. Fourteen species of weeds of 9 families were recorded. Most of them were included in Asteraceae, Fabaceae, Poaceae, and Plantaginaceae. The most important broad leaved and narrow-leaved weeds were Taraxacum officinale L. and Cynodon dactylon [L.] Pers., respectively. Results indicated that the highest frequency (F) (100%), field uniformity (FU) (89.28%), mean field density (MFD) (58.43 m-2) and mean occurrence field density (MOFD) (58.43 m-2) belongs to T. officinale L. of the year 2008. Results were almost the same at year 2009. Taraxacum officinale L. showed the highest relative abundance in both years. | ||
