| چکیده | ||
| به منظور بررسی اثر رقابت علف های هرز بر ویژگی های مرفوفیزیولوژیک، عملکرد و اجزای عملکرد کلزا، آزمایشی در سال زراعی 89 - 1388 در مرکز تحقیقات کشاورزی و منابع طبیعی استان تهران در قالب طرح بلوک های کامل تصادفی با سه تکرار و چهارده تیمار به مرحله اجرا درآمد. تیمارها در دو گروه، به ترتیب رقابت با علف های هرز تا مراحل رشدی سبز شدن، دو برگی، چهار برگی، شش برگی، هشت برگی، ظهور جوانه گل و برداشت و گروه دوم حذف علف های هرز تا مراحل مذکور بود. تداوم رقابت با علف های هرز باعث شد تا به دلیل سایه اندازی علف های هرز، ارتفاع بوته افزایش یابد. نتایج همچنین نشان داد که حذف علف های هرز بر صفاتی همچون تعداد شاخه فرعی در بوته، فاصله اولین شاخه فرعی خورجین دار از زمین، تعداد خورجین در بوته، تعداد دانه در خورجین، وزن هزار دانه، عملکرد بیولوژیک، عملکرد دانه، شاخص برداشت و عملکرد روغن، معنی دار و بر صفاتی مانند طول خورجین و درصد روغن دانه معنی دار نبود. نتایج به دست آمده از این آزمایش نشان داد که بیشترین رقابت علف های هرز با کلزا، بین مراحل سبز شدن تا ظهور جوانه گل می باشد. به طور کلی مشخص شد که مبارزه با علف های هرز در این دوره می تواند به طور معنی داری از کاهش عملکرد جلوگیری نماید. | ||

| چکیده [English] | ||
| In order to investigate the effect of weed competition on morphophysiologic indices, yield and yield components of rapeseed, a research project was conducted using a randomized complete block design with three replications at Natural Resources and Agricultural Research Center of Tehran Province in Varamin, during 2008-2009 growing season. Treatments included periods of weed competition or noncompetition with rapeseed based on growth different stages of crop. Treatments were applied in two groups: I. Weed interference until 2, 4, 6, 8 leaf stages, emergence of flowering bud initiation and harvest stages and II. Weed free treatments until the above mentioned growth stages. The continuity of weed competition to the later stages of crop growth caused that the final height of rapeseed increased by plants which in turn increased the node intervals on the main stem. The results also showed that weed removal time had significant effects on number of secondary branches per plant, height of the lowest pod bearing branch, pod number per plant, seed number per pod, 1000 grain weight, biological and grain yield, harvest index and oil yield, but there were no significant differences between treatments on pod length and percent of oil production. Overall, it is found weed control in this period can prevent yield reduction significantly. | ||
