Growth responses and aquaporin expression in grape genotypes under salinity. Nayer Mohammadkhani*, Reza Heidari, Nasser Abbaspour and Fatemeh Rahmani
نویسندگان: ثبت نشده
چکیده مقاله:
The effects of salinity on growth, leaf area and water relations of two grape genotypes (Gharashani and Shirazi) were studied under 2-week salinity (25, 50 and 100 mM NaCl). Growth and fresh weights of all plant parts were significantly (p

Salinity Effects on Potassium Accumulation and Transporters Expression in Grape (Vitis vinifera L.). Nayer Mohammadkhani1٭, Reza Heidari2 and Nasser Abbaspour2
Hydroponically grown ten grape genotypes (Vitis vinifera L.) were treated with different concentrations of NaCl. Chawga genotype accumulated K+ in its root and shoot even at high salinity. The correlation between Na+ and K+ concentrations in root and lamina of all genotypes was negative (P
متن کاملEffects of salinity on antioxidant system in ten grape genotypes. Nayer Mohammadkhani1 and Nasser Abbaspour2*
Salinity is an important environmental factor that limits plant growth and production. Grape is classified as salt sensitive plants. The object of this study was to evaluate effects of salinity on membrane lipid peroxidation, antioxidant components, and antioxidative enzymes activity in ten grape genotypes native to the regions around Urmia Salt Lake.Malondialdehyde content and protective enzym...
متن کاملGrowth and physiological parameters under salinity stress in Lotus corniculatus. Marjan Azarafshan and Nasser Abbaspour *
Salinity is a main and common stress which decreases the amount of agriculture products and natural plants in many areas of the world. In this study, the effect of salt stress on three varieties of Lotus corniculatus 'Karaj', 'Jolfa', and 'Ardabil' was investigated. Plants were cultured in hydroponic condition with four NaCl treatments (0, 50, 100, 150 mM). The amounts of proline, glycine betai...
متن کاملExpression of related proteins and aquaporin genes in grape (Vitis vinifera L.) under salinity sress
Due to worldwide increasing of salinity, the identification of genes conferring tolerance to plants is important. The aim of this study was to investigate salinity effects on the expression of three genes-related to proteins and aquaporin in grape (Vitis vinifera L.). Based on screening study on 18 grape genotypes, H6 and Gharashani that showed lower decrease in water potential, leaf area, leaf...
متن کاملResponses of growth and antioxidative enzymes to various concentrations of nickel in Zea mays leaves and roots. Fatemeh Ghasemi*, Reza Heidari, Rashid Jameii and Latifeh Purakbar
To assess nickel-induced toxicity in plants, Zea mays seeds were germinated and cultured on nutrient solution with nickel concentrations of 50-200 μM for a period of two weeks. Observed biological makers included biomass, soluble and total protein contents, and the activities of guaiacol peroxidase (GPX), ascorbate peroxidase (APX), catalase (CAT), and phenylalanine ammonia-lyase (PAL) in the l...
متن کاملTobacco responds to salt stress by increased activity of antioxidant enzymes . Ali Asghar Hatamnia1,*, Nasser Abbaspour1, Reza Darvishzadeh2, Fatemeh Rahmani1, Reza Heidari 1 1
In order to understand the response of tobacco to salt stress, antioxidant enzyme activities, plant biomass and ion content were analyzed in two oriental tobacco genotypes (Basma 31 and SPT 406). Tobacco plants were exposed to 0, 50, 100, 150 and 200 mM NaCl for 12 days. The fresh and dry weight as well as shoot and root length of Basma 31 were greater than those of SPT 406 under increasing sal...
