Almond (Prunus amygdalus L.) is commonly grown in water deficit and
saline regions of the world, as well as in Iran. The current study aims to
assess the morphological, nutritional and physiological responses of four
almond cultivars (ʻTalkhʼ, ʻNonpareilʼ, ʻAzarʼ and ʻSanghiʼ) to salinity stress.
Plants were grown under greenhouse conditions and irrigated with modified
Hoagland solution containing of 0, 25, 50 and 75mM NaCl for 90 days.
The experimental design was factorial based on CRD. Increasing in the salinity
concentration was accompanied on more leaf Na concentration and
depression in K concentration in all of the cultivars, although Naþ and Kþ
accumulation pattern was different between cultivars. Nonpareil and
Sanghi maintained better growth in salinity condition, and also nutrient
concentration such as Ca, Mg and K decreased lesser, moreover antioxidant
enzyme activity like APX, SOD, GR and CAT heightened more in
Nonpareil and Sanghi than Talkh and Azar. According to these findings, we
concluded that Nonpareil and Sanghi are more tolerant than Talkh and
Azar to salinity stress, respectively. In conclusion, we deduced that characteristics
such as antioxidant enzymes and macronutrients concentration
might be beneficial for assessment and screening of almond cultivars.
