چکیده

به منظور بررسی تحمل و سازگاری به تنش خشکی در پانزده تودۀ گشنیز (Coriandrum sativum L.) بومی ایران، سه آزمایش به‌طور جداگانه در شرایط کشتزار در قالب طرح بلوک‌های کامل تصادفی در سه تکرار انجام شد. در آزمایش‌های اول، دوم و سوم به ترتیب توده‌های گشنیز در معرض آبیاری معمولی، تنش یک‌باره و تنش تدریجی قرار گرفتند. در این تحقیق شمار هفده صفت پدیدشناختی (فنولوژیکی)، ریخت‌شناختی (مورفولوژیکی) و فیزیولوژیکی اندازه‌گیری شد. نتایج تجزیۀ واریانس مرکب چندمتغیره و تک‌متغیره اختلاف معنی‌دار بین آزمایش‌ها و توده‌ها را از لحاظ تحمل به تنش خشکی نشان دادند. نتایج مقایسۀ‌ میانگین کل آزمایش‌ها به روش کمترین اختلاف‌های معنی‌دار، برای بیشتر صفات تفاوت معنی‌داری را بین آزمایش‌ها نشان داد. بیشترین تأثیر تنش خشکی بر عملکرد میوه بود. نمودار‌های سه‌بعدی مربوط به شاخص میانگین هندسی بهره‌وری برای عملکرد و میزان اسانس‌های میوه نشان داد که تودۀ شمارۀ 10 می‌تواند برای تولید میوه و اسانس در مناطق با خشکی انتهای فصل توصیه شود. بیشترین میزان وراثت‌پذیری عمومی در آزمایش اول برای شمار میوه در هر بوته و در دو آزمایش همراه با تنش برای صفت شاخص برداشت مشاهده شد. با در نظر گرفتن وراثت‌پذیری و درصد پیشرفت ژنتیکی مورد انتظار در صفات شمار و عملکرد میوه، تولید رقم دورگ (هیبرید) برای بهبود این صفات می‌تواند پیشنهاد می‌شود.

چکیده [English]

In order to investigate drought stress tolerance and adaptation in 15 Iranian endemic coriander (Coriandrum sativum L.), three experiments were conducted separately through randomized complete block design whit three replications in field conditions. In experiments, the coriander populations were well watered, stressed at one step and stressed gradually, respectively. In this research, 17 phonological, morphological and physiological traits were measured. Results of univariate and multivariate combined analysis of variance showed the difference among experiments and coriander populations for drought tolerance. Means comparison through LSD test showed significant difference among experiments for the most of traits. The highest effect of drought stress was on the fruit yield. Three dimensional diagrams based on geometric mean productivity for fruit yield and fruit essential oil content revealed that P10 can be introduced for fruit and essential oil production in regions that have drought stress problem at the end of growth season. The highest broad sense heritability was observed for fruit number per plant in the first experiment and harvest index in both drought stressed experiments. By considering heritability and genetic gain of fruit number and fruit yield traits, production of hybrid variety can be suggested for improving these traits.
