Analysis of morphological traits in pine needles and mistletoe
leaves
One day before the labeling, 10 mistletoe leaves and 20 pine needles of
each selected tree were harvested separately for leaf morphological
measurements. Leaf area was measured using a scanner and image analysis
software (PIXSTAT v1.3, WSL, Birmensdorf, Switzerland). Fresh weight of
all leaves was firstly measured, and dry weight was measured after
oven-drying the samples at 65°C for 5 d, and leaf water content and leaf
mass per area (LMA) were then calculated.
