Influence of rootstocks on ‘Orlando’ tangelo leaf elemental concentration

Abstract

Abstract The influence of 10 rootstocks on leaf elemental concentrations and their relationship with yield, tree growth, leaf fresh weight and dry matter of ‘Orlando’ tangelo (C. parodisi Macf. x C. reticulata Blanco) was studied under the arid climate of southwestern Arizona. ‘Orlando’ tangelo trees on Carrizo citrange [(C sinensis (L.) Osbeck x Poncirus trifoliata (L.) Raf.], Yuma citrange (P. trifoliata x C. sinensis), Taiwanica (C. taiwanica) and Volkamer lemon (C. limon Burm f.) had larger canopy and higher yield than the trees on Savage citrange (P. trifoliata x C. sinensis), Ichang pummelo (C. ichangensis hyb.) and Palestine sweet lime (C. limettoides Tan.). Leaves of trees on Carrizo citrange were heavier but those on Savage citrange had higher percent dry matter than those on other rootstocks. Trees on macrophylla (Alemow) (C macrophylla Wester) had significantly higher leaf N and Mn while those on Carrizo, Yuma and Savage citranges had lower leaf N than the trees on other rootstocks. Trees on Vo...
