Upon completion of the drought stress experiment, shoot and root samples from three treatment pots were isolated, washed, and desiccated using filter paper. The fresh weight (FW) of the samples was initially measured, followed by drying at a constant temperature of 60°C until a steady weight was achieved. Subsequently, the samples were weighed again to obtain the dry weight (DW), which was then used to calculate the root-crown ratio indicators utilizing the following formula:
