Achene mucilage content of six Turkish endemic Tripleurospermum (Asteraceae) taxa and its ecological significance
Abstract
In this study, the achene mucilage content of six Turkish endemic Tripleurospermum taxa, namely T. baytopianum E. Hossain, T. conoclinium (Boiss. & Bal.) Hayek, T. fissurale (Sosn.) E. Hossain, T. hygrophilum (Bornm.) Bornm., T. rosellum (Boiss. & Orph.) Hayek var. album E. Hossain and T. ziganaense Inceer & Hayirlioglu-Ayaz was determined by micro-staining reactions. Within the examined taxa, the mucilage cells on the achene surface are capable of forming a musilage envelope resembling a gel during hydration. The mucilage is heterogeneous and chemically contains pectin and cellulose. There are differences in the capacities of mucilage forming as well as adhesive to soil of the achenes in the studied taxa. The mucilage could have great importance in distribution and adaptation of Tripleurospermum taxa to diverse environments.

Türkiye endemiği altı Tripleurospermum (Asteraceae) taksonunun aken müsilaj içeriği ve ekolojik önemi
Abstract
Bu çalışmada, Türkiye endemiği altı Tripleurospermum taksonunun, T. baytopianum E. Hossain, T. conoclinium (Boiss. & Bal.) Hayek, T. fissurale (Sosn.) E. Hossain, T. hygrophilum (Bornm.) Bornm., T. rosellum (Boiss. & Orph.) Hayek var. album E. Hossain ve T. ziganaense Inceer & Hayirlioğlu-Ayaz, aken musilaj içeriği mikroboyama ile belirlenmiştir. İncelenen taksonlarda, musilaj hücreleri perikarp yüzeyinde bulunur ve hidrasyon sırasında müsilaj zarf oluşumu ile karakterize edilir. Bu taksonlardaki müsilaj kimyasal olarak pektin ve selüloz yapısındadır. İncelenen taksonlarda müsilaj oluşturma kapasitelerinin yanı sıra akenlerin toprağa yapışma kapasiteleri arasında da farklılıklar vardır. Müsilaj, Tripleurospermum taksonlarının farklı ortamlara dağılımında ve uyumunda büyük öneme sahip olabilir.
