Seed Geometric Morphometrics of Neottioid Orchids

This study aims to investigate orchid seed variation between some representatives of Neottieae, C. rubra, L. abortivum, Neottia nidus-avis, and N. (Listera) ovata, naturally distributed in our country by using geometric morphometric analyses based on 2-dimensional landmarks. For this purpose, a total 95 specimens were evaluated. The results ANOVA, PCA, discriminant showed significant shape size differences the species. Size statically among all species except for that rubra ovata. Based most prominent chalazal micropylar regions as well whole width. Discriminant analysis was also statistically cross-validation scores highly powerful distinguish with ranging from 60% 88%. Regression allometric effect similar trend across current results, is promising morphological within plant parts. present terms widespread use such studies field botany, especially context systematic or functional morphology.
