| Abstract: | Simple techniques and growth regulator treatments to improve micro-grafting success of ‘Mexican’ lime, ‘Valencia’ orange and ‘Star Ruby’ grapefruit were studied. Most scion cultivars grafted best on ‘Carrizo’ citrange Poncirus trifoliata (L.) Rat. x Citrus sinensis (L.) Osbeck]. Dipping the shoot-tip in 2,4-D or kinetin before grafting doubled the percentage of successful grafts. Highest grafting success occurred when the scion shoot-tip was placed in an inverted-T incision on the epicotyl of the rootstock. |
