Descripción
‘Cleopatra’ tangerine ( Citrus reshni hort. ex Tanaka) is a commonly used rootstock in the piedmont of Meta department, Colombia for establishing of commercial citrus orchards. Have allowed a late production entrance rootstock and produced big plants when grafted with tangelo ‘Minneola’ ( C. reticulata Blanco x C. paradise Macf), decreasing the productive efficiency in plants and hard crop practices. The evaluated performance were as follows: tree size, productive efficiency and fruit quality of tangelo ‘Minneola’ grafted in six rootstocks. It found that the cumulated production of 11 years was better with Citrumelo ‘Swingle’ ( Citrus paradisi Macf. × Poncirus trifoliata (L.) Raf) with 1388.3 kg tree -1 , followed by ‘Cleopatra’ ( Citrus reshni hort. ex Tanaka) with 893.2 kg.tree -1 , in last place was ‘Carrizo’ ( Citrus sinensis Osb. × Poncirustrifoliata (L.) Raf) with 182.9 kg tree -1 . The other rootstocks, had a medium production. The greatest height and canopy value, was found with ‘Cleopatra’ without significant differences with Citrumelo ‘Swingle’. In fruit quality no significant differences occurred.
