چکیده مقاله :
به منظور بررسی تاثیر آبیاری تکمیلی و کاربرد میکوریزا و ازتوباکتر بر مولفه های پرشدن دانه، محتوای کلروفیل و عملکرد دانه جو دیم رقم سهند، آزمایش فاکتوریلی در قالب طرح پایه بلوک های کامل تصادفی با سه تکرار در سال 1395 در روستای ویند کلخوران اردبیل انجام شد. فاکتورهای آزمایش شامل سطوح آبیاری (عدم آبیاری یا زراعت دیم، آبیاری تکمیلی در 50 درصد مراحل آبستنی و سنبله دهی) و کاربرد کودهای زیستی در چهار سطح (عدم کاربرد کودهای زیستی به عنوان شاهد، کاربرد قارچ میکوریزا، ازتوباکتر، کاربرد توام ازتوباکتر و قارچ میکوریزا) بودند. نتایج نشان داد که بیش ترین محتوای کلروفیلa ،b ، کارتنوئید، کلروفیل کل، فلورسانس حداکثر، فلورسانس متغیر و عملکرد کوانتومی، طول دوره پر شدن دانه و حداکثر وزن دانه در آبیاری تکمیلی در مرحله آبستنی با کاربرد توام قارچ میکوریزا و ازتوباکتر، و کم ترین مقادیر این صفات در شرایط دیم و بدون کاربرد کودهای زیستی به دست آمد. بیش ترین سرعت پر شدن دانه در شرایط دیم بدون کاربرد کودهای زیستی و کم ترین آن در شرایط آبیاری تکمیلی در مرحله آبستنی با کاربرد قارچ میکوریزا به‌دست آمد. آبیاری تکمیلی در مرحله آبستنی با کاربرد توام میکوریزا و ازتوباکتر عملکرد دانه را 87/29 درصد در مقایسه با عدم کاربرد کودهای زیستی تحت شرایط دیم افزایش داد. بر اساس نتایج، به نظر می رسد کاربرد کودهای زیستی و آبیاری تکمیلی می تواند به واسطه بهبود کلروفیل و مولفه های پر شدن دانه، عملکرد جو دیم را افزایش دهد.
In order to study the effects of supplementary irrigation and application of mycorrhiza and azetobacter on grain filling components, chlorophyll content, and grain yield of rain fed barley (Var. Sahand), a factorial experiment was conducted based on a randomized complete block design with three replications in the village of Khalkhoran Viand, Ardabil province during 2017. Factors of the experiment included irrigation levels (no irrigation as rain fed, supplementary irrigation at 50% heading, and booting stages) and biofertilizers application at four levels (without biofertilizers as control, application of mycorrhizal fungi, application of azetobacter, and combined application of mycorrhiza and azetobacter). Results showed that the highest chlorophyll a (1.76 mg/g FW), chlorophyll b (0.88 mg/g FW), carotenoid (0.83 mg/g FW), chlorophyll total contents (2.64 mg/g FW), maximum fluorescence (1433.2), variable fluorescence (1281.3), quantum yield (0.847), grain filling period (32.06 days), and maximum grain weight (58.3 mg) were obtained under supplementary irrigation treatment at boot stage with both application of mycorrhiza and azetobacter while the minimum levels of these traits were obtained under rain fed condition without application of biofertilizers. Moreover, the highest grain filling rate (1.9 mg/day) was obtained under rain fed condition and no application of biofertilizers while the lowest rate was obtained under supplementary irrigation at boot stage with application of mycorrhiza. Supplementary irrigation at boot stage and combined application of mycorrhiza and azetobacter increased grain yield by 29.87% in comparison with no application of biofertilizers under rain fed condition. Based on the results, it seems that application of biofertilizers and supplementary irrigation can increase grain yield of rain fed barley through improving chlorophyll content and grain filling components.
