The aim of the study was to determine the correlation between the mechanical resistance of iris seed capsules and seeds to foraging. The principal component analysis (PCA) demonstrated that the first main component referred to the variety type in 68%, and the second main component described the stage of the ontogenetic development of the plant in 26%. As indicated by the values of each parameter measured, all the parameters were found to exert a strong impact on the variability of the analyzed system. The occurrence of weevil infestation was also strongly but negatively correlated with seed wall thickness and capsule wall thickness. There was a correlation of seed max load and seed mass with the occurrence of the weevil. The analysis of the mechanical resistance of iris seed capsules (in June 9.28 N and September 6.27 N for and in June 6.59 N and September 2.94 N for ) and seeds (in June 15.97 N and September 344.90 N for and in June 16.60 N and September 174.46 N for ) showed significant differences between the terms and species. The PCA analysis revealed that the first variable was correlated with the occurrence of weevil foraging.
本研究旨在确定虹膜种子囊和种子对觅食的机械抗性之间的相关性。主成分分析（PCA）表明，第一个主成分在 68%的情况下与品种类型有关，第二个主成分在 26%的情况下描述了植物个体发育阶段。根据测量的每个参数的值，发现所有参数都对分析系统的可变性产生了强烈影响。象鼻虫侵害的发生也与种子壁厚度和胶囊壁厚度呈强烈负相关。种子最大负荷和种子质量与象鼻虫的发生呈正相关。对虹膜种子囊（在 6 月为 9.28N 和 9 月为 6.27N，对 为 6 月为 6.59N 和 9 月为 2.94N）和种子（在 6 月为 15.97N 和 9 月为 344.90N，对 为 6 月为 16.60N 和 9 月为 174.46N）的机械抗性进行分析，发现两者之间存在显著差异。PCA 分析表明，第一个变量与象鼻虫觅食的发生有关。
