Progress in the study of grey mould of Lilium spp.
Grey mould disease,which is mainly caused by the fungus Botrytis elliptica,leads to severe losses in lily cut-flower and bulb production.This paper reviewed the infection cycle and pathogenic mechanism of the fungus Botrytis elliptica,the mechanism of host disease resistance,and the control of grey mould.Future research directions were also proposed.This review provides a reference for the in-depth analysis of the mechanism of lily resistance to grey mould and the breeding of high-resistant lily varieties to achieve effective prevention and control of lily grey mould.
