Abstract AR
نفذت تجربتي أصص موسمي 2017 و 2018 لاختبار تأثير السيلينيوم كرش ورقي في صورهة (Na2SeO4) بتركيز 2.5 و 5 ميكرومولار علي النمو صبغات البناء الضوئي والتوازن بين عنصرى Na/K و المحصول لنباتات الذرة تحت ثلاث مستويات من الملوحة (0 50 و 100 مللي مولار NaCl).
وقد دلت النتائج على ان معامله 2.5 ميكرومولار حققت أعلي قيم معنويه في الوزن الجاف للأوراق و السيقان كلوروفيل أ و كلوروفيل ب و K محصول الحبوب الكلي و امتلاء الحبوب من خلال وزن ال100 حبه.
علي العكس من ذلك كان هناك نقص معنزى في تركيز Na نسبة Na/K.
بينما لم تبدى الكاروتينات اي تغييرات معنويه بين النباتات المعاملة بالسيلينيوم وغير المعاملة.
Abstract EN
Two pot experiments during the seasons of 2017 and 2018 were conducted to investigate the effect of Se as Na2SeO4 (2.5 and 5 µM) as foliar applications on growth, photosynthetic pigments, Na/K homeostasis and eventually the yield of maize plants grown under three different levels of salinity (0, 50 and 100 mM NaCl).
The results indicated that Se at 2.5 µM recorded the highest significant values in leaves and stem dry weights, total grain yield plant-1 and grain filling as indicated by the weight of 100 kernels; As well as, Chl a, Chl b and K concentrations.
On contrary, there was a significant decrease in Na concentration and Na/K ratio.
Additionally, carotenoids did not reveal any significant changes between Se-treated plants and the untreated ones.
