English Abstract
Response of pistachio rootstocks (Pistachio atlantica and Ashouri) to different salicylic acid (SA) concentrations, under three concentrations of total electrode of irrigation water was studied in a pot experiment in a partially controlled glass house belonging to the Agricultural Research Station, Faculty of Agriculture, Al-Rabba, Mu'ta University, during the period from March-December, 2006.
Three total electrode concentrations were used (control, 80, 160meq / L) and four levels of SA (control, 105, 103, 10 mM) as pretreatment.
Half Hoagland nutrient concentration was supplied repeatedly along the experiment period.
Specific vegetative growth parameters, biochemical content of leaves as well as mineral content and water use efficiency were studied.
The chloride toxicity of the higher total electrode concentrations of irrigation water reduced fresh and dry weight of leaves, shoots, and roots.
The results showed that salicylic acid at 10 mM negatively affects both fresh and dry weight of atlantica roots, while for Ashouri ; the highest positive effect of SA concerning fresh and dry weight root for both of rootstocks was obtained at 10 5mM.
Results of proline content gave a positive relationship with increasing electrode concentration but it was negatively related with the levels of salicylic acid.
Increasing electrode concentration of the irrigation water caused reduction in chlorophyll, total soluble sugar, K contents, and increased Ca, Mg, Na, and Cl content.
A significant decrease occurred in total soluble sugars content as a result of pretreatment with salicylic acid, the lowest value was obtained by 10mM of salicylic acid on atlantica, while on Ashouri, a significant increase resulted as SA concentration increased.
At the end of the experiment, Cl that accumulated in leaves was found to be affected negatively by pretreatment with salicylic acid.
A pronounced reduction in water use efficiency of both rootstocks occurred, as electrode concentration of the irrigation water increased but a pronounced increase occurred with salicylic acid mainly at 10mM.
