Different responses of tolerant and sensitive banana (Musa spp.) genotypes to low temperature stress. (A,B) The control plant and the youngest fully-developed leaf of Musa spp. ABB Dajiao (chilling-tolerant genotype). (C) The youngest fully-developed leaf of the tolerant genotype incubated at 10°C for 3 days. (D) The youngest fully-developed leaf of the tolerant genotype incubated at 7°C for 3 days, showing a slight loss in plant cell turgor. (E,F) The control plant and the youngest fully-developed leaf of Musa spp. AAA cv. Baxijiao (chilling-sensitive genotype). (G) The youngest fully-developed leaf of the sensitive genotype incubated at 10°C for 3 days, showing hydrophanous spots appearing on the leaf (arrows). (H) The youngest fully-developed leaf of the sensitive genotype incubated at 7°C for 3 days, showing more severe chilling injury symptom.
