    Abstract

    This study investigated the effects of exogenous methionine (Met) and different phosphate (PO4) concentrations on Cd uptake and translocation in Valeriana officinalis L. Seedlings were grown in nutrient solutions with three different concentrations of phosphate (900, 1200, and 1500?μM) for two weeks, then exposed for 4 days to 10?μM Cd, either in presence or absence of 400?μM methionine. The Met treatment decreased root Cd accumulation by up to 40%, while it enhanced Cd uptake into the shoots by 50%. In absence of Met, shoot Cd uptake was not affected by the level of phosphate application, although root Cd contents increased. The latter effect was entirely due to increased apoplastic Cd binding. In presence of Met, the Cd accumulation of

    Journal PapersJournal of Plant Nutrition , Volume 43 , Issue 4, 2020 February 25, {Pages 526-537 }

    Abstract

    Cultivation systems used for rose production often impose salt stress in arid and semiarid regions of the world. While boron (B) has been widely reported as a nutrient that can alleviate the adverse effects of salt stress on crop growth and yield, inadequate information is available regarding the emerging pattern of rose plant responses to an appropriate concentration of boron under salinity condition is available. To address this issue, an experiment was conducted to evaluate the effects of different levels of B application (24, 34, 44, and 54 μM) on Rosa plants under two levels of salt stress (1.8 and 2.9 dS m−1). Cut rose (Rosa hybrida L.) “Dolce Vita” was grown hydroponically in containers with a mixture of cocopeat and perlite

    Abstract

    This study was conducted in the south-east of Fars Province, Iran, between 2010 and 2012, to study the effect of pruning and supplemental irrigation (SI) on growth characteristics and yield of rainfed fig trees under drought conditions. The irrigation treatments comprised: no irrigation; one irrigation event in the last month of winter; one irrigation event in mid-spring; one irrigation event in midsummer; and two irrigations, one in the last month of winter and one in mid-spring. Pruning treatments consisted of moderate thinning out of one-year-old lateral branches; severe thinning out of one-year-old lateral branches; moderate heading back; and green pruning. The results regarding the growth characteristics showed positively response of

    Journal PapersEnvironmental and experimental botany , Volume 135 , 2017 March 1, {Pages 56-62 }

    Abstract

    ATPase activity and ATP-dependent H+ transport have been analyzed in membrane vesicles isolated from a winter wheat cultivar (Triticum aestivum cv. Back Cross Rushan) which was exposed to different concentrations of nickel (Ni) and histidine (His). Seedlings were grown in a modified Johnson nutrient solution and then exposed to the uptake solution containing 10?μM Ni to which either 100?μM His or no amino acid was added. Control plants were transplanted to nutrient solutions free of Ni and His. According to our results, using Ni alone or together with His enhanced the activity of plasma membrane (PM) H+-ATPase and resulted in a higher pH gradient across the plasma membrane. The highest initial rate of H+-pumping by PM H+-ATPase also achie

    Effects of nickel on zinc uptake and translocation in two wheat cultivars differing in zinc efficiency

    Abstract

    Low availability of zinc (Zn) in soil can limit plant growth and yields. In soils with elevated nickel (Ni) concentrations, which can be due to anthropogenic and geogenic sources, Zn uptake by plants may be inhibited due to competition between the two elements. Here we used a hydroponic system to investigate short-term effects of a wide range of Ni concentrations on Zn uptake and translocation in two spring wheat cultivars at two different levels of Zn supply. Seedlings of the Zn efficient cultivar Back Cross Rushan and the Zn inefficient cultivar Kavir were grown for three weeks in Zn and Ni free nutrient solution and then exposed for two days to either 0, 1, 2, 10, 20, or 40?μM Ni and either 400?nM or 2?μM Zn, before they were harvested

    Abstract

    The aim of this field experiment was to investigate the efficiency of foliar-applied zinc (Zn) in the form of mineral (ZnSO4) and complexed with lysine (Lys), methionine (Met), or threonine (Thr) as a strategy to improve yield and nutritional quality of two onion cultivars (Allium cepa L. cvs. Behbahan and Perimavera). Different Zn sources and free amino acids (i.e., Lys, Met, and Thr) were applied once at the early rapid vegetative growth stage and once 45 d later at concentration of 0.5%. A control treatment (free of Zn and amino acids) was also used. Plant response to Zn foliar application varied depending on the cultivar and Zn sources. In ‘Behbahan’, foliar application of Zn from all sources significantly increased bulb yield while

    Root uptake and translocation of nickel in wheat as affected by histidine

    Journal PapersJournal of plant physiology , Volume 184 , 2015 July 20, {Pages 14-Aug }

    Abstract

    The role of histidine (His) on root uptake, xylem loading and root to shoot transport of nickel (Ni) was investigated in a winter (Triticum aestivum cv. Back Cross) and a durum wheat (Triticum durum cv. Durum) cultivar. Seedlings were grown in a modified Johnson nutrient solution and exposed to 10?μM of Ni and 100?μM of histidine (His) as no His, Ni (10)?+?His (100) and Ni(His) in a 1:1 mole ratio (1:1) complex. In our study, the presence of vanadate (a metabolic inhibitor) resulted in a significant decrease of root Ni uptake, indicating that a part of Ni uptake by the plant root is energy-dependent. Addition of His significantly increased the Ni content in shoots and roots of both wheat cultivars. The data suggest that the Ni(His) is mos

    Abstract

    Understanding how complexes with amino acids in soil solution affect plant zinc (Zn) uptake may aid in optimising plant Zn nutrition. We investigated the influence of histidine and glycine in nutrient solution on apoplastic and symplastic uptake and root-to-shoot translocation of Zn in a triticale (?Triticosecale cv. Elinor) and a bread wheat cultivar (Triticum aestivum cv. Back Cross Rushan). Six-week-old seedlings of the two cultivars were transferred to a nutrient solution containing 20 ?m Zn, to which 50 ?m histidine, 50 ?m glycine or no amino acids were added. Control plants were transplanted to nutrient solution with no Zn or amino acids. Higher concentrations of Zn were found in root and shoots of wheat and triticale plants sup

    Journal PapersJournal of plant physiology , Volume 171 , Issue 7, 2014 April 15, {Pages 531-536 }

    Abstract

    This study investigated the effect of exogenous amino acids on apoplastic and symplastic uptake and root to shoot translocation of nickel (Ni) in two wheat cultivars. Seedlings of a bread (Triticum aestivum cv. Back Cross) and a durum wheat cultivar (T. durum cv. Durum) were grown in a modified Johnson nutrient solution and exposed to two levels (50 and 100?μM) of histidine, glycine, and glutamine. Application of amino acids resulted in increasing symplastic to apoplastic Ni ratio in roots of both wheat cultivars, although glutamine and glycine were more effective than histidine under our experimental conditions. The amino acid used in the present study generally increased the relative transport of Ni from the roots to shoots in both wheat

    Journal PapersArchives of Agronomy and Soil Science , Volume 59 , Issue 4, 2013 April 1, {Pages 559-571 }

    Abstract

    The objective of the investigation was to evaluate the effect of applied phosphorus (P) and cadmium (Cd) on Cd chemical forms determined by sequential extraction and the relationship between these forms and plant responses, i.e., dry weights, concentration, and total uptake of Cd and P in a greenhouse experiment. Treatments consisted of five levels of Cd (5, 10, 20, 40 and 80 mg kg−1 soil as cadmium sulfate) and four levels of P (0, 15, 30 and 60 mg kg−1 soil as monocalcium phosphate), which were added to the soil and left to equilibrate for 1 month under greenhouse conditions. Spinach seeds (Spinacea oleracea L., cv Viroflay) were sown and then grown for 8 weeks. The chemical composition in the aerial part of the pant and soil was dete
