The effect of Isaria cateinannulata root irrigation on the chlorophyll content of Fagopyrum tataricum leaves at different stages. (a) Chlorophyll content in leaves of Fagopyrum tataricum seedlings (15 days after root irrigation) is measured in mg/g. (b) Chlorophyll content in leaves of Fagopyrum tataricum during the filling stage (30 days after root irrigation) is measured in mg/g. ‘*’ indicates that the difference between the experimental group and the control group is significant, and ‘**’ indicates that the difference between the experimental group and the control group is extremely significant.
