Table 2.

Analysis on the rate of increase (decrease) of the water content of component organs under different periods.

Period	LD period	RLD period	MD period	RMD period
Rate of RWC (%/d)	-0.91	0.24	-0.20	-0.09
Rate of SWC (%/d)	-0.41	-0.33	-0.24	0.09
Rate of LWC (%/d)	-0.12	0.22	0.11	-0.20

The LD period, RLD period, MD period, and RMD period represent the light drought period, the period of rehydration after light drought, the moderate drought period, and the period of rehydration after moderate drought, respectively. The rate of RWC, SWC, and LWC represents the increase or decrease rate of the water content in the root, stem, and leaf.
