| Inhoud: |
Growth of Chrysanthemum morifolium 'Bright Golden Anne' was assessed after application of irrigation water containing five alkalinity levels (0, 100, 250, 500, 1000 mg/liter bicarbonate) in a greenhouse study. Irrigation water having alkalinity levels exceeding 500 (week 12)or 1000 (week 6) mg/liter bicarbonate affected plant height and fresh and dry weights. High levels of irrigation water alkalinity altered nutrient availability in the growing medium and plant tissue nutrient content. This was attributed to a rise in growing medium pH. Between 6 and 12 weeks, the critical level of alkalinity in water that altered growing medium nutrient availability and plant growth decreased from 1000 to 500 mg/liter bicarbonate. Acid additions improved plant growth for the water treatment containing 500 mg/liter bicarbonate. Sulfuric acid was the most effective acid treatment. |
