چکیده

به‌منظور بررسی اثر سامانه هیدروژلی کند رهای حاوی اوره بر عملکرد، اجزای عملکرد و ویژگی‏های فیزیولوژیک جو تحت تنش کم‌آبی، آزمایشی به‌صورت فاکتوریل در قالب طرح بلوک‌های کامل تصادفی با سه تکرار در سال زراعی 97-1396 در گلخانه پردیس ابوریحان-دانشگاه تهران، انجام شد. ترکیب سطوح فاکتوریل به‌صورت عامل کودی حاوی نیتروژن از منبع اوره در پنج سطح عدم کاربرد کود نیتروژن، معادل 125 و 65 کیلوگرم در هکتار نیتروژن به صورت فاقد و دارای سامانه هیدروژلی و عامل تنش کم‌آبی در سه سطح 70، 50 و 30 درصد رطوبت ظرفیت زراعی بودند. کم‌آبی سبب کاهش عملکرد دانه و عملکرد زیستی، اجزای عملکرد، محتوی نسبی آب و شاخص تغییرات SPAD شد. بیشترین عملکرد دانه در گلدان (9/41 گرم) مربوط به مقدار بیشتر نیتروژن در قالب سامانه کند‌رها بود و بین مقدار این صفت در میزان بیشتر نیتروژن فاقد هیدروژل (5/41 گرم) و در مقدار کمتر نیتروژن در قالب سامانه کندرها (1/39 گرم) تفاوت معنی‌داری مشاهده نشد. در اکثر صفات، بین تیمارهای دارای سامانه هیدروژلی و تیمار مقدار بیشتر نیتروژن فاقد هیدروژل، تفاوت معنی‌داری نبود. در تنش، استفاده از سامانه هیدروژلی کندرها در هر دو مقدار نیتروژن توانست عملکرد زیستی و شاخص تغییرات کلروفیل SPAD مطلوب‌تری را حاصل نماید. کاربرد نیتروژن بصورت سامانه کودی کندرها، به‌خصوص در شرایط تنش، به استفاده نیتروژن فاقد سامانه هیدروژلی، برتری داشت.

چکیده [English]

In order to study the effect of slow release hydrogel-urea complex (SRHUC) on yield, yield components and physiological traits of barley under water deficit, an experiment was performed in 2017-2018 and conducted as factorial in Randomized Complete Block Design (RCBD) in three replications in greenhouse of Aburaihan campus of University of Tehran. The combination of factorial levels were as fertilization factor containing nitrogen (N) from urea source in five levels of no use of N, equivalent 125 and 65 kg.ha-1 N (without SRHUC) as CU-N125 and CU-N65 and equivalent 125 and 65 kg.ha-1 N with SRHUC as SRHUC-N125 and SRHUC-N65 and water deficit in three levels of 70, 50 and 30% of FC. Water deficit decreased yield and yield components, RWC and SPAD. The highest grain yield in a pot belonged to SRHUC-N125 (41.9 g) and there was no significant difference between CU-N125 (41.5 g) and SRHUC-N65 (39.1 g). For most of the traits, there was no significant difference between SRHUC-N125 and SRHUC-N65 and CU-N125. Under stress, utilization of SRHUC for both N amount could generate a better biological yield and SPAD index. Using N in the form of SRHUC was preferred to using of N without SRHUC, especially under stressed conditions.
