ارزیابی ارقام برنج بر اساس مقاومت به جوانه‌زنی پیش از برداشت (pre-harvest sprouting)
جوانه‌زنی پیش از برداشت یکی از عوامل کاهش دهنده عملکرد و کیفیت دانه برنج در شرایط آب و هوایی مرطوب و مصادف با بارندگی در زمان برداشت محصول می‌باشد. در این تحقیق 34 رقم بومی و اصلاح شده ایرانی و خارجی برنج از نظر جوانه‌زنی پیش از برداشت (در شرایط زنده) و برخی صفات مرتبط با آن مورد ارزیابی قرار گرفتند. نتایج تجزیه واریانس نشان داد که ارقام مورد بررسی از لحاظ جوانه‌زنی پیش از برداشت و سایر صفات دا...
متن کاملFactors Affecting Pre-harvest Sprouting Resistance in Wheat (triticum Aestivum L
Pre-harvest sprouting (PHS) is one of the most important factors to affect the yield and quality of crops worldwide especially in wet harvest period. Breeding PHS-resistant cultivars has important implications to improve the wheat quality and production. The PHS is determined by environmental conditions, inner factors and interaction between these factors. We here reviewed recent advances influ...
متن کاملEffect of Pre-Harvest Sprouting on Physicochemical Properties of Starch in Wheat
Pre-harvest sprouting (PHS) in wheat (Triticum aestivum L.) occurs when physiologically mature kernels begin germinating in the spike. The objective of this study was to provide fundamental information on physicochemical changes of starch due to PHS in Hard Red Spring (HRS) and Hard White Spring (HWS) wheat. The mean values of α-amylase activity of non-sprouted and sprouted wheat samples were 0...
متن کاملGenome-wide association study of pre-harvest sprouting resistance in Chinese wheat founder parents
Pre-harvest sprouting (PHS) is a major abiotic factor affecting grain weight and quality, and is caused by an early break in seed dormancy. Association mapping (AM) is used to detect correlations between phenotypes and genotypes based on linkage disequilibrium (LD) in wheat breeding programs. We evaluated seed dormancy in 80 Chinese wheat founder parents in five environments and performed a gen...
متن کاملComparison of α-amylase activity in some sprouting Nigerian cereals
The yield and characteristics of Alpha-amylase obtained from some sprouting Nigeria cereals (maize, acha, rice and sorghum) were compared using standard procedures. The result indicated maximum α-amylase yield was attained from 72-120 hours of sprouting cereals). Of all the sprouted cereals, acha gave rise to the highest amylase yield (16.6 ± 0.02x10 and the least was exhibited by maize (11.0±0...
