Figure 2: The relationship between maximum photosynthetic performance and seasonal maintenance into the cool season in cycads.

From: Speed versus endurance tradeoff in plants: Leaves with higher photosynthetic rates show stronger seasonal declines

Figure 2

(a) The relationships between seasonal decrease in net photosynthetic rate per unit leaf area (Aa) and warm season Aa (a), between seasonal decrease in net photosynthetic rate per unit leaf mass (Am) and warm season Am (b), and between percent seasonal decrease in photosynthetic rate (A) and warm season Aa (c). Points denote means ± SEs. Red points represent cycads in Fairylake Botanical Garden (FBG), while green points cycads in Xishuangbanna Tropical Botanical Garden (XTBG). The black lines are standardized major axis (SMA) lines fitted to all the points. The red line is a SMA line fitted to the species in FBG, while green line species in XTBG. *P < 0.05; **P < 0.01; ***P < 0.001. Photo credit: Y-J Zhang.
