In vitro dehydration rate and the leaves stomata observation. a Dehydration rate experiment of detached leaves (40-mm in length) was conducted for 15 h at room temperature (20 ± 2 °C) to measure the weight of leaves. The mass ratio was calculated by the weight after drought treatment divided by the original weight before treatment. b Stomata of leaves under drought stress were observed using the TM3000 microscope. Stomata were observed randomly in 50 visual sections with the same area. The experiments were repeated three times
