In this study, the effects of salinity stress (NaCl) on the activity of Catalase (CAT), Guaiacol Peroxidase (POD), and Superoxide dismutase (SOD) were studied in leaves of fifteen oilseed rape (Brassica napus L.) cultivars (Champlain, Hayola401, Licord, Modena, NK Aviator, NK Karibik, NK Octan, Okapy, Opera, PF, RGS, RNX 3621, SLM046, Talayeh, Zarfam). Plants were grown in a greenhouse under co...

the influence of salinity on the different polyamine fractions (free, conjugated, and bound) was compared in a natrophilic halophyte (beta vulgaris l. cv. ic) and a salt sensitive glycophyte (nicotiana rustica l. cv. basmas). low-level salinity (25 mm nacl) and high salinity (150 and 50 mm nacl for sugar beet and tobacco, respectively) were supplied in hydroponics. under low salinity shoot dry ...

soil salinity poses considerable and increasing problems for agriculture, and is receiving much attention from plant breeders. the identification of genes whose expression enables plants to adapt to and/or tolerate salt stress is essential for breeding programs, but little is known about the genetic mechanisms of traits in saline conditions. the data obtained from 75 families produced by crossi...

BACKGROUND AND OBJECTIVES Essential oils may improve the utilization of nutrients by ruminal microorganisms. The aim of this study was to assess the effect of different doses of ajowan essential oils (AEO) on growth and fibrolytic activity of anaerobic fungi, and generic distribution of ciliated protozoa (in vitro). MATERIAL AND METHODS Different doses of AEO (0, 150, 300, 450 and 600 ppm) we...

the effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (lycopersicon esculentum l.) were investigated in gorgan, iran. a factorial experiment was conducted based on rcbd with four nacl levels (0, 50, 100, and 150 mm) and four cacl2 levels (0, 100, 200 and 300 mg l-1). data of growth, yield and leaf’s ca, k, and na content were subjected to analyze ...

the study was conducted to evaluate the effect of seed priming on root growth of two barley cultivars (hordeum vulgare l.) under salinity stress was performed in phytogel. the treatments included two cultivars of barely (yusuf and maquie), levels of seed priming (control, hydro-priming and priming with 4.35 g l-1 of urea) and four levels of nacl salinity stress (0, 0.2, 0.3 m). the experiment w...

This research was carried out in 2014 and 2015 to assess the effects of salicylic acid (SA)(0 and 1 mM) and abscisic acid (ABA) (0 and 50 µM) on essential oil content and yield ofajowan (Carum copticum L.) organs under different irrigation intervals (I1, I2, I3, I4: irrigationafter 70, 100, 130 and 160 mm evaporation, respectively). Plants were sprayed by SA and ABAat vegetative and reproductiv...

the purpose of this study was to elucidate some factors affecting the growth of salmonella typhimurium. these factors included carum copticum essential oil (0%, 0.015%, 0.03% and 0.06%), temperature (25 ˚c and 35 ˚c), ph (5, 6 and 7) and inoculum size (103 and 105  cfu ml-1). brain heart infusion broth was used as the growth medium. there were 48 treatment combinations and the experiment was ca...

crisis due to global warming and its associated damaging consequences, including salinity, it is essential to develop plant resistance to salinity level. in this study, an experiment was conducted using different levels of salinity (0.05, 0.1, 0.15 and 0.2% sodium chloride) had on rosa hybrida, as the most important cut flowers in the world. results showed that by increasing of salinity, sodium...
