| Abstract: | Trials were carried out on grapefruit (Citrus paradisi Macf.) ‘Marsh Seedless’ and orange (C. sinensis L.) ‘Valencia’, both on Sour orange (C. aurantium L.) rootstock. Shortening the interval between sprinkler irrigations increased the occurrence of lime-induced chlorosis (LIC), as indicated by reduced leaf chlorophyll and peroxidase enzyme activity. Drip irrigation, on the other hand, corrected LIC and increased leaf chlorophyll, peroxidase activity and photosynthesis. |
