| Abstract | ||
| Calcium is one of the most important minerals that plays important role in resistance to plant pests and diseases, One of the accumulation sites of this element is the plant cell wall. The presence of calcium pectate in the cell wall is essential for plant survival. Lack of calcium in pistachio fruit causes the Endocarp Lesion in early May during the millet stage and fruit is growing. Calcium spraying is one of the strategies to eliminate the Endocarp Lesion that has become prevalent in recent years. various calcium-containing compounds are used, including various chelates and calcium fertilizers. The seeds of two cultivars of pistachio Badami Zarand and Qazvini were planted in hydroponic culture medium. After one month, complete nutrient solution (HF) with the percentage of elements and the same solution but without calcium (H) were added to the pots. The nutrient solutions were changed monthly. Calcium-containing solutions including calcium chelate, calcium nitrate and calcium acetate were prepared at a concentration of 2 per thousand and all pots were sprayed in 4 varieties at intervals of 5 days. After 4 months, seedling height, crown diameter and concentrations of calcium, magnesium and phosphorus in the plant were measured. The results showed that foliar application of different calcium-containing compounds had no significant effect on calcium concentration of pistachio seedlings. However, the use of calcium in the nutrient solution of the culture medium and also the type of cultivar had a significant effect on the calcium concentration in the plant. Also, foliar application of calcium acetate caused a significant increase in phosphorus concentration in the plant. It seems that foliar application of calcium acetate probably increased phosphorus uptake due to its acidic nature. | ||
