Salicylic acid-deficient NahG transgenic lines and sid2 mutants were used to evaluate the role of this compound in the development of the short-lived, annual plant Arabidopsis thaliana, with a particular focus on the interplay between salicylic acid and other phytohormones. Low salicylic acid levels led to increased growth, as well as to smaller abscisic acid levels and reduced damage to PSII (...
Many efforts have been taken to increase the vase-life of cut flowers by using different methods and materials. In this research, the effect of applying citric acid and salicylic acid at pre-harvest stage on vase-life of rose (Rosa hybrida L. cv. Avalanch) was investigated. The factorial experiment was carried out as a randomized complete blocks design. Three levels of citric acid concentration...
sulforaphane is a strong anticarsenogen compound which is produced in broccoli. it seems salt stress improves sulforaphane production via systemic acquired resistance. to obtain suitable salt concentration and for having more content of sulforaphane with controlling germination percentage, nacl in 5 levels 0, 50, 100, 150, 200 mm (0, 4.53, 9.125, 13.68, 18.25 ds/m ) and salicylic acid in 3 leve...
The objective of this research was to evaluate the effect of salicylic acid and gibberellic acid on germination characteristics and changes of proline, protein and catalase activity of Brassica napus seedlings under Cu(SO4) stress. The experimental design was factorial with complete randomized design as a base design with 3 replications. The first factor was 4 levels of Cu(SO4) stress (0, 10, 2...
The seed pretreatment with salicylic acid has an important role in improving seed germination and increasing plant resistance to environmental stresses. This study was performed to investigate the effect of salicylic acid on seed germination of Milk thistle under salinity and drought stress. A factorial experiment was conducted in a completely randomized design with three replications. Treatmen...
We investigated the effects of acetylsalicylic acid, salicylic acid, sulfisoxazole, and phenobarbital-at concentrations at or just above those in serum after therapy-on results of the 2(4’ -hydroxyazobenzene) benzoic acid (HABA) and bromcresol green (BCG) methods for measuring serum albumin. Although the HABA method was more prone to such interference, only interference by salicylic acid with t...
In order to investigate the effects of humic acid and salicylic acid on quantitative and qualitative properties and nutrients concentrations in leaves of cotton var. Khordad, a two-year field experiment were conducted at the Tehran Agricultural and Natural Resources Research and education Center during 2018with randomized complete block design as factorial with two factors as follow: soil ap...
frost in early spring is one of the limiting factors in the production of grape. chemicals offer useful approach to reduce low temperature-induced damages. different concentrations of salicylic acid including: 0 (control), 0.5, 1 and 2 mm were sprayed twice on 10 year-old ‘bidaneh sefid’ grape vines at full bloom stage and changes in leaf soluble carbohydrates, proline and protein levels were m...
in order to study the effects of salicylic acid and selenium application on yield and yield components of rainfed wheat cultivars, a field experimental was carried out as factorial based on randomized complete block design with four replications in the research station of islamic azad university- arak branch, iran in 2010-2011 growing season. the treatments were salicylic acid and selenium. sal...
Salicylic acid can mitigate the impacts of salinity and drought stresses in crops. To study the effect of salicylic acid under iso-osmotic drought and salt stresses on nutrients absorption and growth of linseed (Linum usitatissimum L.), an experiment was conducted based on a completely randomized design with three replications in Yasouj University in 2016. Treatments included salinity and droug...
