چکیده

به‌منظور بررسی تأثیر تنش خشکی بر عملکرد و اجزای عملکرد برخی از توده‌های بومی رازیانه (Foeniculum vulgare Mill.)، آزمایشی به‌صورت اسپلیت‌پلات بر پایۀ طرح بلوک‌های کامل تصادفی با سه تکرار در سال 1391 در مزرعۀ تحقیقاتی دانشکدۀ کشاورزی دانشگاه زنجان اجرا شد. در این آزمایش تنش خشکی در دو سطح شامل شاهد (آبیاری کامل) و تنش خشکی در مرحلۀ زایشی در کرت‌های اصلی و پنج تودۀ بومی رازیانه شامل توده‌های زنجان، لرستان، اصفهان، همدان و کاشان در کرت‌های فرعی بررسی شد. نتایج نشان داد که تأثیر تنش خشکی بر اکثر صفات شامل اجزای عملکرد، عملکرد زیست‌توده، عملکرد دانه، درصد و عملکرد اسانس معنی‌دار (05/0P≤) بود. توده‌های رازیانه نیز از لحاظ تمامی صفات مورد بررسی تفاوت معنی‌داری (01/0P≤) داشتند. اکثر صفات مورد بررسی تحت شرایط تنش خشکی کاهش یافتند. بیشترین عملکرد دانه (3284 کیلوگرم در هکتار) از تودۀ زنجان و تحت شرایط شاهد، و کمترین مقدار صفت مذکور (1306 کیلوگرم در هکتار) از تودۀ اصفهان و تحت شرایط تنش خشکی به‌دست آمد. توده‌های کاشان و اصفهان به‌ترتیب دارای بیشترین و کمترین عملکرد اسانس بودند.

چکیده [English]

In order to evaluate the effect of drought stress on grain yield and its components of fennel accessions, a field experiment was conducted as a split plot based on complete randomized block design with three replications. This experiment was conducted in research farm of Agricultural faculty of Zanjan University in 2012. In this study water stress in two levels included control and drought stress at reproductive stage were assigned to the main plots and five Iranian accessions of fennel included Zanjan, Lorestan, Esfahan, Hamedan and Kashan were assigned to the sub plots. The results showed that the effect of drought stress on grain yield and its components, biomass yield, grain essential oil percent and essential oil yield was significant (p≤0.05). Also there were significant differences between Fennel populations about all studied traits. Majority of measured traits decreased under drought stress condition. So the highest grain yield (3284 kg/ha) was obtained in Zanjan accession and control conditions and the lowest amount of mentioned trait (1306 kg/ha) was obtained in Esfahan accession under drought stress condition. Kashan and Isfahan accessions had the highest and lowest essential oil yield respectively.
