چکیده انگلیسی
The effect of potassium (K) on celery (Apium graveolens L.) growth and cation uptake was studied under different calcium (Ca) and magnesium (Mg) levels in substrate culture in the greenhouse. Shoot and root fresh and dry weight and leaf area increased with increasing K application up to 8 mmol lâ1. High level of Ca and Mg (16 mmol lâ1) significantly inhibited celery growth compared to lower levels (4 and 8 mmol lâ1). In this study, K concentration in celery increased with increasing K application up to 8 mmol lâ1, but did not change significantly with further increases in K application. In contrast to K, the opposite trends were found for Na, Ca and Mg concentrations in celery. The order of K concentration in celery root, stalk and leaf was: stalk > root > leaf and for Ca was: leaf > stalk > root. Mg concentration in celery root and leaf was high when compared with stalk. In addition, 8 and 16 mmol lâ1 of Ca and Mg levels increased celery cation uptake as compared with 4 mmol lâ1 of Ca and Mg level. This study suggested that 4-8 mmol lâ1 K applications under the condition of 8 mmol lâ1 of Ca and Mg level were appropriate for the improvement of celery growth and nutrient uptake
