Freezing resistance evaluation of rose stems during frost dehardening using electrical impedance tomography
Abstract Background Electrical impedance tomography (EIT) has rarely been applied in plant science, particularly to study plant resistance to abiotic and biotic stresses. In this study, we evaluated the freezing resistance of floribunda roses (Rosa Floribunda) during frost dehardening using the EIT...
