“…On the contrary, the current study found that sample area increased with altitude in both subspecies of P. microcarpa . This corroborates our previous study on leaf morphology of these two taxa in which we found altitude to have a minimal effect on leaf shape, but affected leaf size positively (Mollman et al, 2022).…”

“…The current study aimed to assess whether these taxa vary significantly in venation features, which, alongside leaf shape and indumentum, may have adaptive significance (Brodribb et al, 2010). This builds on our previous work on P. microcarpa, in which we found that the differences in leaf morphology between long-shoot and short-shoot leaves were greater than those between leaves of these two infraspecific taxa (Mollman et al, 2022). Heteroblastic development affecting shoot and leaf anatomy and morphology is well documented in many Rosaceae taxa (Costes et al, 2014;Robertson et al, 1992;Rouffa & Gunckel, 1951), but studies on many aspects of this phenomenon are lacking, especially for Prunus.…”

Using 33 specimens collected from across their range in Turkey, we demonstrate that the subspecies of Prunus microcarpa C.A.Mey react very differently to altitude. We first outline a simplified, flexible protocol for sectioning and removing the epidermis of small, difficult‐to‐image leaves for leaf vein studies. We then used venation analysis software to evaluate the two subspecies of this wild cherry in relation to altitude. We also found key differences in venation features between short‐shoot and long‐shoot leaves for each taxon. Differences include statistically significant negative correlation between vein density, and positive correlation between areole area and altitude in long‐shoot leaves of Prunus microcarpa subsp. microcarpa, while its short‐shoot leaves had a positive relationship between maximum areole area, and negative relationship between vein density, numbers of veins and endpoints. Meanwhile, P. microcarpa subsp. tortuosa (Boiss. & Hausskn.) Browicz recorded trends that were largely opposite of this, but beside vein thickness and areole area, were not statistically significant. This difference may be part of each taxon's overarching syndrome of anatomical and morphological adaptations to its external environment.Research Highlights Features of vein density and thickness fell, while areole area and vein length rose with altitude in P. microcarpa. P. microcarpa subsp. tortuosa showed opposite trends, but reacted less strongly to altitude. Short‐shoot and long‐shoot have significantly different venation parameters. Using sections proportionate to leaf size is useful to compare venation of leaves that vary due to dimorphism. We discuss protocol strategies for imaging of difficult leaves for venation analyses.
