Water stress, nano silica, and digoxin effects on minerals, chlorophyll index, and growth in ryegrass
Water shortage worldwide mandates minimum use of irrigation water with maximumefficiency and productivity in all agricultural crops, landscape plants and turf. The objective inthis experiment was to study the effect of two levels of evapotranspiration-based (ETc) droughtin combination with two levels of nanosilicon dioxide (SiO2; NanSi1=1 mM and NanSi=2 mM),two levels of digoxin (Dig1=0.25 mg.l...
متن کاملIn vitro studies on effects of Ferrioxamine B on chickpea (Cicer arietinum L.) growth and chlorophyll content
The availability of iron for roots has been demonstrated as a critical factor in plant production. The addition of synthetic iron chelates to soil is a common practice in agriculture, which is not economically beneficial. Besides, chemical iron fertilizers cause many problems such as food contamination and environmental pollution. Development of natural Ferrioxamine B as an efficient and safe i...
متن کاملdetermining the nickel toxicity on chlorophyll content, hill reaction and growth in maize seedlings
to assess nickel-induced toxicity in plants, zea mays seeds were germinated and cultured on nutrient solution with nickel concentrations of 0, 50, 100 and 200 μm for a period of two weeks. its effects on the growth, hill reaction and photosynthetic pigments content were then investigated. the fresh and dry weight of leaves and roots increased in 50 μm nickel, but decreased in 100 and 200 μm. th...
متن کاملRole of Selenite and Selenate Uptake by Maize Plants in Chlorophyll A and B Content
Abstract—Extracting and determining chlorophyll pigments (chlorophyll a and b) in green leaves are the procedures based on the solvent extraction of pigments in samples using N,Ndimethylformamide as the extractant. In this study, two species of soluble inorganic selenium forms, selenite (Se) and selenate (Se) at different concentrations were investigated on maize plants that were growing in nut...
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
