Table 2. The growth status of well-watered (WW) and drought-stressed (DS) P. mongolica seedlings on March 10^th and March 25^th, 2013.

Treatment	Leaf length (cm, 3/10/2013)	Leaf width (cm, 3/10/2013)	Leaf length (cm, 3/25/2013)	Leaf width (cm, 3/25/2013)	Number of leaves shed
WW	3.28±0.16a	1.31±0.08a	3.78±0.23a	1.52±0.21ab	0.17±0.16b
DS	3.26±0.22a	1.33±0.15a	3.37±0.19b	1.37±0.16b	3.33±1.33a

Different letters in the same column indicate a significant difference between the WW and DS treatments: Duncan’s multiple range tests at the 5% level (n = 12). The presented data are the means of 12 replicates, and the standard errors of the means are shown.
