safflower oil seed has high adaptability to different kinds of abiotic stresses such as drought and salinity. the aim of this study was to evaluate the effects of drought stress at different phenological stages on relative water content (rwc), leaf canopy temperature, seed yield and its components in spring types of safflower. the study was carried out in east azarbaijan research center for agr...

in order to investigate the effect of cycocel on different growth aspects of two olive cultivars (mary and mission), a greenhouse experiment was conducted taking into account three factors of: cycocel at three levels (0, 500 and 1000 mg l-1), drought stress of three levels (irrigated at 5, 10 and 15 days intervals) and two olive cultivars (mary and mission) in a factorial experiment based on ra...

Introduction: The aim of this study was to examine in the lipid profile during 3.6 years and anthropometric parameters in Iranian adults the changes during 3.6 year body mass index (BMI). Materials and methods: Among participants of the Tehran lipid and glucose study (TLGS), 2940 non-diabetic adults, aged 20 years and older, who remained within the same BMI group during the two phases of the su...

considering the extent of salinity in soils of iran, abiotic stresses such as salinity are serious threat to agricultural production, yield and essential oil of medicinal plants. recognition of threshold for salt tolerance and determining the slope of yield loss in medicinal plants has an important role in the selection of suitable lands for their cultivation. the effect of salinity stress on s...

Salinity is one of the major environmental constraints affecting agriculture in regions world. This study was conducted to evaluate effect exogenous nitric oxide (NO) treatments on two chickpea cultivars (Cagatay and Inci) under salt stress conditions. Different NO doses (0. 75 100 μM sodium nitroprusside (SNP)) as an source were applied plants grown saline (presence 50 mM NaCl) nonsaline In th...

Drought stress is a major environmental factor limiting plant growth. Selection of drought-tolerant plants critical importance in vegetation restoration and forestation programs. Alnus subcordata Acer velutinum are two valuable, dominant, endemic species the Hyrcanian forests. There fast-growing significant diffuse-porous hardwood afforestation reforestation. One-year old seedlings both were ex...

This study investigated the effects of cerium (Ce) on growth and fruit quality strawberries under salt stress. The findings revealed that stress markedly enhanced activities antioxidant enzymes increased contents malonaldehyde (MDA) hydrogen peroxide (H2O2) in leaves anthocyanins, phenolic compounds, vitamin C (Vc), soluble sugar (SS) titratable acid (TA) fruits. Ce improved ascorbate peroxidas...

Drought is one of the main abiotic stress factor that limits plant growth and development. effects on Borago officinalis L. (borage) plants in terms physiological antioxidant responses have been evaluated this study. In parallel with purpose, relative rate (RGR), leaf water content (RWC), osmotic potential, chlorophyll fluorescence (Fv/Fm), lipid peroxidation, hydrogen peroxide (H2O2) level, su...
