Investigation the amount of macro and micro elements, chlorophyll content and chlorophyll index of selected almond cultivars on the GF677 and GF677 in alkali conditions

. In this research, response of almond cultivars included Tuono, Nonpareil,Mamaee, Shokofeh, Sahand, Azar, A200, A230 and 79 on GF677 and the GF677 in alkali conditions base on factorial experiment in completely randomized design with two factors and with three replication was investigated. The results showed that, with the increasing concentration of potassium bicarbonate in the water of irrigation,% nitrogen, potassium, calcium, magnesium and phosphorus, and the content of zinc and ironwas reduced and necrotic leaves increased but the rate of increase or decrease in the traits measured in the between cultivars together showed significant differences. In total the traits measured showed that Sh 12 anymore and then the cultivars of the A230 and Shokofeh as the most tolerant cultivars and sahand, 79 as the most susceptible cultivars in the high potassium bicarbonate concentrations were detected. Also, Sh12, A230 and Shokofeh could well tolerant in 15 mg potassium bicarbonate concentration in irrigation water. Also Sh 12 30 mMpotassium bicarbonate concentration partly would tolerant in the water of irrigation. As well as the results of this study showed that the type of a scion in increase the resistance the rootstock of GF677 to the high concentration of potassium bicarbonate was effective . Most scions (except Sahand and 79), has more resistance to high concentrations of potassium bicarbonate in comparison with nongraft rootstock.
