Effects of Warming on Chlorophyll Degradation and Carbohydrate Accumulation of Alpine Herbaceous Species during Plant Senescence on the Tibetan Plateau
Figure 2
Effects of warming on chlorophyll concentration during the leaf senescence.
Decline in chlorophyll concentration for E. regelii (A), D. caeruleum (B), S. mussotii (C) and E. nutans (D) in warming and control quadrates during the leaf senescence in 2011. Error bars are SE (n = 3). Asterisks indicate significant differences for each collection in warming and control quadrates: ** indicate P<0.01; * indicates P<0.05.
