Measurement of plant physiological index after CSL-gel treatment
A total of 50 pieces of CSL-gel or SL-gel were buried in the soil, and each plant was given 10 mL of water every day for consecutive 14 days and placed in a constant temperature growth room at 25 °C (12 h of light and 12 h of darkness). After 14 days, the plant height, plant width, leaf width, fresh weight, and dry weight of N. benthamiana were measured. Each treatment group has twelve replicates.
