YPYakup PolatCukurova University ŞAŞevket AlpVan Yüzüncü Yıl Üniversitesi

Key Points

The study aims to evaluate the photosynthetic pigment profiles of climbing and creeping plant species for urban green applications.
Assess chlorophyll a, b, and chlorophyll a/b ratios using spectrophotometric methods.
Statistical comparison of data with Principal Component Analysis (PCA) and hierarchical clustering.
Evaluate physiological performance for urban greening applications.
Pigment values varied by analysis method but showed consistent overall trends.
The chlorophyll a/b ratio significantly differed across methods (p < 0.05).
Species were classified based on pigment characteristics using PCA and clustering techniques.

Abstract

Objective: This study aimed to evaluate the photosynthetic pigment profiles of climbing and creeping plant species commonly used in the semi-arid urban landscape of Van, Türkiye. The objective was to assess their physiological performance and determine their suitability for green infrastructure and vertical greening applications.Material and Methods: Chlorophyll a (Chl a), chlorophyll b (Chl b), and Chl a/b ratios were determined using three different spectrophotometric approaches. The obtained data were statistically compared, and species were classified according to their pigment characteristics using Principal Component Analysis (PCA) and hierarchical clustering.Results: Absolute pigment values varied among analytical methods, but overall trends were consistent. The Chl a/b ratio differed significantly among methods (p
