We provide a step-by-step protocol for assessing poplar resistance to stem canker pathogens using an in vivo leaf inoculation method. This method is especially suitable for large-scale assessment of Cytospora chrysosperma and Botryosphaeria dothidea canker disease resistance in poplar breeding progeny in China.

Min Li^*1,2, Donglin Wang^*1,2, Yuchen Fu^1,2, Mingzhuo Zhao³, Zheng Li^1,2, Wanna Shen^1,2, Long Pan^1,2, Xiaohua Su⁴, Jiaping Zhao^1,2

Here, we present a protocol to induce the production of adventitious roots (ARs) through the phloem- or epidermis-girdle fungal pathogen inoculation pathway, which is suitable for the study of root biology and the light response-related physiological processes in poplar.
