چکیده

به منظور بررسی تاثیر مداخله علف‌های هرز بر عملکرد و اجزاء عملکرد لوبیا (Phaseolus vulgaris L.)، آزمایشی به صورت طرح کرت‌های خرد شده در قالب بلوک‌های کامل تصادفی با چهار تکرار در ایستگاه ملی تحقیقات لوبیا در خمین طی سال های 1378 و 1379 اجرا شد. کرت‌های اصلی شامل آلودگی طبیعی به علف‌های هرز و کنترل کامل علف‌های هرز در تمام فصل رشدی لوبیا و کرت‌های فرعی شامل هشت رقم/لاین لوبیا شامل دهقان، دانشکده، ناز، گلی، تلاش، صدری، محلی خمین و COS16 بود. مقایسه میانگین صفات نشان داد که تداخل علف‌های هرز عملکرد، تعداد دانه در بوته، تعداد دانه در غلاف و تعداد غلاف در بوته را به ترتیب 45%، 39%، 5% و 36% کاهش داد. رقم گلی و تلاش با بیشترین شاخص تحمل رقابت به علف های ارقام برتر شناخته شد. بررسی ضرایب همبستگی نشان دهنده همبستگی منفی و بسیار معنی‌دار وزن خشک علف‌های هرز با عملکرد و اجزاء عملکرد ارقام لوبیا بود.

چکیده [English]

In order to determine the effect of weeds on yield and yield components of common bean (Phaseolus vulgaris L.), this research was carried out as split plot in randomized complete block, with four replications, in Khomein Bean Research Station during 1999 and 2000. There were two plots including naturally contaminated with weeds, and complete weed control. There were also eight subplots containing the following ban cultivars/lines: Dehghan, Daneshkadeh, Naz, Goli, Talash, Mahali Khomein, Sadri and Coc16 bean. Mean comparisons of traits showed that presence of weeds caused loss of 45% in yield, 39% in number of seeds for plant, 5.1% number of seeds per pod, 36% number of pods in studied cultivars/lines. Goli and Talash with the highest ability of weed competition were superior among studied cultivars. The coefficients of correlation indicated negative and significant correlation of weed dry weight with yield.
