'Hongmian miyou' (Citrus grandis L. Osbeck) is mutated from 'Guanxi miyou', with a different spongy layer coloration. Trifoliate orange (Poncirus trifoliata) is widely used as rootstocks in 'Guanxi miyou' grafting, whereas 'Hongmian miyou' is incompatible with available trifoliate orange rootstocks. To explore the reasons for the etiolation of leaves of 'Hongmian miyou'/trifoliate orange, anato...
