in order to determine the effects of zinc foliar application on the vegetative characteristics, yield and fruit quality in strawberry (fragaria × ananassa duch) cv kordestan under salinity stress conditions, an experiment was carried out hydroponically in glasshouse as a controlled environment during 2009 through 2010. three levels of nacl (0, 15, 30 mm) and three levels of zn (0, 1.5, 3 g/l) w...
In order to study the interaction effects of salinity and ascorbic acid on the photosynthetic pigments, soluble sugar, proline, and protein in Satureja khuzestanica plant, factorial experiment was conducted in a completely randomized design (salinity in 4 levels 0, 40, 80 and 120g in 100kg soil and ascorbic acid in 2 levels 0 and 2 mM ) with 6 replicates. The results showed that salt stress red...
This experiment was conducted with two genotypes of lentil (MLC321 and MLC323), two levels of calcium (0 and 5 mM Ca2+ as CaSO4) and five salinity levels (0, 4, 8, 12 and 16 dS/m) as a factorial experiment, based on completely randomized design with three replications. Seeds were sown in plastic pots and sampling of seedlings was done after 6 weeks. Results showed that in both genotypes, plant ...
soil and water salinity is a major constraint in arid and semi-arid regions. in order to study the impact of water salinity on physiological characteristics and dry matter production of six linseed genotypes, a 4-replicate factorial randomized complete block pot experiment was conducted. salinity consisted of four levels: 0 (control), 35 (low salinity), 70 (intermediate salinity) and 105 mm (se...
background & aim: milk thistle [silybum marianum (l.) gaertn] is an annual or biennial plant, native to the mediterranean area, which has spread in north and south of iran. a fruit of milk thistle contains a relatively high amount (approx. 20%) of oil, which exhibits wound-healing, anti-burn, and hepatoprotective properties. experimental: in this research, a pot experiment was conducted usi...
To evaluate the effects of different levels of nitrogen (N) and salinity on yield and growth indices of tomato, a factorial experiment with a completely randomized design and three replications was performed in greenhouse conditions. Treatments included four levels of salinity (0.5, 2.5, 4.5 and 6.5 dS/m as NaCl) and four levels of N (0, 60, 120 and 240 kg/ha). The results showed that fruit yie...
Application of grafting technique could be an approach for increasing salinity resistance of tomato cultivars. To assess the impact of grafting on resistance of tomato to salinity, two varieties of conventional tomato called Hamra and Kevin were grafted on a salt-resistant base, called AR-9704, using chisel grafting method, and were grown in the greenhouse, using a hydroponic system, under thre...
Salinity significantly limits leaf photosynthesis but the factors causing the limitation in salt-stressed leaves remain unclear. In the present work, photosynthetic and biochemical traits were investigated in four rice genotypes under two NaCl concentration (0 and 150 mM) to assess the stomatal, mesophyll and biochemical contributions to reduced photosynthetic rate (A) in salt-stressed leaves. ...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
Selenium (Se) is a beneficial element for plant but at high concentrations, it is toxic and causes in plant growth retardation. There is limited information about the effects of Se on salinity-induced damages on wheat. Therefore this study was carried out to investigate interaction of salinity and Se on root and shoot dry matter yield, activity of GPX, and concentrations and uptake of selected ...
