Plants with tropical origin including those of the Cucurbitaceae family are generally sensitive to chilling stress and harmed by low temperatures. In this study, we evaluated five plant growth regulators and compared the effectiveness of each substance in improving chilling stress tolerance of cucumber (Cucumis sativus L., cv. Super dominos) seedlings. The experiment was conducted as a randomiz...

In order to study the effects of foliar application of potassium (K) and boron (B) and dificit irrigation treatments on quantitative and qualitative traits of sugar beet (Beta vulgaris L.), a split plot experiment was conducted based on randomized complete block design with three replications in the Research Field of Shahrekord University, Shahrekord, Iran, in 2019. The main plots were allocate...

Extended Abstract Introduction and Objective: In order to investigate the effect of foliar application of main elements and micronutrients on morpho-physiological and yield traits of rice plants with the aim of increasing yield and reducing the use of chemical fertilizers, experiments in the cropping years 2015-2016 and 2016-2017 in the research farms of Nowshahr city (Mazandaran) was implemen...

Salinity stress is one of the most important abiotic stresses which impares growth and productivity of plants worldwide. Foliar application of chemicals such as salicylic acid (SA) is among potential solutions to ameliorate damaging effects of salinity. The present research was carried out during 2015-2016 growing season in Research Greenhouse of University of Kurdistan to study the influence o...

Water stress is the most important abiotic stress in crop production. Silicium (Si) is the second most abundant element in the soil with beneficial effects on plant tolerance to biotic and abiotic stresses. In order to evaluate the effect of this element in increasing tolerance to water deficit in wheat, a factorial experiment was conducted based on a completely randomized design with three rep...
