(a) Leaf area index and (b) height of <i>Heracleum sosnowskyi</i> leaf layers.
<p>Plant groups and plant parts: s–seedlings (N = 10); j—juvenile plants (N = 14), v—vegetative adult plants (N = 15); m3–m6 are generative plant metameres (N = 38): m3—leaves of first three metameres, and m4, m5, and m6—leaves of 4<sup>th</sup>, 5<sup>th</sup>, and 6<sup>th</sup> metameres, respectively.</p
Parameters of the Light Curve of Net Photosynthesis in <i>Heracleum sosnowskyi</i> Leaves.
<p>QY: photosynthetic quantum yield (calculated as the tangent of the slope ratio of the light curve at low light intensities: 0–100 μM photons m<sup>-2</sup>c<sup>-1</sup>), LCP: Light Compensation Point is the light intensity at which the total CO<sub>2</sub>-exchange is equal to zero, P<sub>MAX</sub>: maximum photosynthesis rate, P<sub>max</sub>*—maximum photosynthesis rate calculated by SLA, IRA: intensity of radiation adaptation, P<sub>IRA</sub>: photosynthesis rate at IRA. For the QY P-value < 0.0001. The mean and standard error of mean of samples is shown.</p
