Salinity of soil is a major abiotic stress limiting the crop production and growth of peppermint. The aim of study was assessment the plant growth regulators efficacy (salicylic acid (SA), jasmonic acid (JA), brassinosteroids (BRs), and non-application of hormone as control) on physiological traits of peppermint under salinity stress (0, 30, and 60 mM). The experiment was conducted using the co...

the impacts of salicylic acid and silicon on some physiological parameters of maize seedlings in the presence ofcadmium (100 μm) were investigated. inhibitory effects of cadmium on seedling growth resulted in reduced shoot and root fresh weight, low percentage of relative water content, low chlorophyll, free proline and soluble sugars contents and a low rate of lipid peroxidation. results indic...

Seedlings of maize (Zea mays L. cv WF9 x Mo 17) growing at low water potentials in vermiculite contained greatly increased proline concentrations in the primary root growth zone. Proline levels were particularly high toward the apex, where elongation rates have been shown to be completely maintained over a wide range of water potentials. Proline concentration increased even in quite mild treatm...

The present study deals with the effects of allelochemicals present in leachate on the drought response of maize plants. Nicotiana plumbaginifolia was selected as a donor plant. 12-d-old maize (Zea mays L. cv. Uttam) seedlings with and without leachate were subjected to water stress (WS) by withholding water supply for 6 days. Leaf water status, photosynthetic pigments, protein content, proline...

The effects of irrigation water salinity on growth, chlorophyll contents, proline and nutrients accumulation and K/Na ratio in three walnut cultivars was investigated. Three irrigation water salinity levels with electrical conductivities of 1,5, 3, and 5.0 dS/m and tap water as a control treatment were used in a randomized design with four replications. Irrigation practices were realized by con...

This study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (Triticum aestivum L.) cultivars (Azar2, Darab2, Shiraz, and Falat) inoculated with the fungus Glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the School of Agriculture, Shir...
