چکیده

کیفیت دانه گندم‏ نه تنها میزان بازدهی و تولید آرد را تحت تأثیر قرار می‏دهد بلکه سبب تولید فرآورده هایی با خصوصیات تکنولوژیکی و حسی مطلوب‏تر و ماندگاری بالاتر می‏شود و موجب کاهش ضایعات و افزایش بهره‏وری، بهبود کارایی زنجیره فرایند تولید از مزرعه تا سفره می گردد. پژوهش حاضر به منظور ارزیابی وضعیت کیفیت دانه گندم‏های آبی تولیدی زارعین در اقلیم گرم و خشک جنوب کشور در سال‏های زراعی 1400-1397 اجرا شد. بدین منظور تعداد 642 نمونه دانه گندم از ده استان واقع در این اقلیم جمع‏آوری و خصوصیات فیزیکی دانه و ویژگی‏های کیفیت فیزیکی و شیمیایی آرد حاصل برای هر رقم در هر استان مورد ارزیابی قرار گرفت. نتایج نشان داد که استان فارس با 4/2±1/43 گرم و استان کهگیلویه و بویراحمد با 5/3±1/36 گرم به‏ترتیب بیشترین و کمترین وزن هزار دانه را به خود اختصاص دادند. رقم چمران 2 در استان فارس با 1/2±5/45 گرم بیشترین و در استان کهگیلویه و بویراحمد با 8/3±5/35 گرم کمترین وزن هزار دانه را داشت. علاوه بر این نمونه‏های گندم تولیدی در استان‏ های این اقلیم از نظر وزن هکتولیتر در گروه بسیار سنگین (میانگین 8/0±2/80 کیلوگرم بر هکتولیتر) قرار گرفتند. از سوی دیگر بیشترین میزان پروتئین دانه در نمونه‏های گندم دو استان خوزستان و بوشهر (4/12 درصد) مشاهده شد و میانگین میزان پروتئین نمونه‏های گندم در استان های این اقلیم در سه سال زراعی 3/0±1/12 درصد بود. استان فارس از بیشترین میزان گلوتن مرطوب با 4/1±0/27 درصد نیز برخوردار بود. با ارزیابی سختی دانه نیز مشخص گردیدکه رقم مهرگان در استان بوشهر با 4/4±8/52 از بیشترین و در استان لرستان با 4/1±0/49 از کمترین شاخص سختی دانه برخوردار بود. بیشترین و کمترین شاخص سختی دانه، شاخص گلوتن و حجم رسوب زلنی و ارتفاع رسوب SDS نیز به‏ترتیب در نمونه‏های گندم استان خوزستان و کهگیلویه و بویراحمد مشاهده شد. درنهایت با توجه به کیفیت متنوع ارقام گندم نان آبی در کشور، که بسیار متأثر از تنوع آب و هوایی و مدیریت مزرعه می‏باشد، پیشنهاد می شود با توزیع یکنواخت و متعادل دانه گندم نان آبی با کیفیت بالای تولیدی در استان های اقلیم گرم و خشک جنوب، از کیفیت مطلوب محصول این استان ها برای بهبود فراورده‏‎های حاصل از گندم نان در سایر استان‏های کشور نیز بهره جست.

چکیده [English]

The quality of bread wheat grain not only affects the efficiency and production of flour, but it also contributes to the production of a product with more favorable technological and sensory characteristics and longer shelf life which by reducing waste and increasing productivity ensures the improvement of production chain efficiency from farm to table. Therefore, the current research was carried out to evaluate grain quality of irrigated bread wheat produced by farmers in the southern warm and dry agro-climatic zone provinces in 2018-2021. For this purpose, 642 irrigated bread wheat grain samples were collected from 10 provinces in the southern warm and dry agro-climatic zone of Iran, and the physical properties of the grain and the physico-chemical characteristics of flour for each cultivar in each province were evaluated. The results showed that Fars province with 43.1±2.4 g and Kohgiluyeh & Boyer-Ahmad province with 36.1±3.5 g had the highest and lowest 1000 grain weight, respectively. Cv. Chamran 2 had the highest (45.5±2.1 g) 1000 grain weight in Fars and the lowest (35.5±3.8 g) in Kohgiluyeh & Boyer-Ahmad. Also, the wheat grain samples produced in this agro-climatic zone were identified as “very heavy grain” considering average hectoliter weight (80.2±0.8 kg/hL). On the other hand, the highest protein content was observed in Khuzestan (12.4%) and Bushehr (12.1±0.3%) provinces, respectively. Fars province had the highest (27.0±1.4%) wet gluten content. By evaluating the grain hardness, it was revealed that cv. Mehregan had the highest (52.8±4.4) grain hardness index in Bushehr province and the lowest (49.0±1.4) in Lorestan. The highest and lowest grain hardness index, gluten index, zeleny sedimentation volume and SDS sedimentation height were observed in grain samples from Khuzestan and Kohgiluyeh & Boyer-Ahmad provinces, respectively. Finally, considering the observed variation in quality properties of grain samples of irrigated bread wheat cultivars in Iran which is affected by the differences in agro-climatic and field management practices, it is suggested that wheat grains produced, with high quality, in the southern warm and dry agro-climatic zone be used to improve the quality of end-use products of grains with lower quality produced in some other provinces in Iran.
