Karadeniz bölgesinde yayılış gösteren bazı orkidelerin perikarp anatomisi ve yüzey mikromorfolojisi

Abstract

Bu çalışmada, bazı orkide türlerine ait meyvelerin önemli özelliklerini belirlemek ve hangi özelliklerin ekolojik veya habitat tercihleriyle ilişkili olduğunu tespit etmek için perikarp anatomisi ve mikromorfolojisi incelenmiştir. Bu amaçla, Karadeniz Bölgesi’nde 19 orkide taksonuna ait örnekler toplanmıştır. Standart tekniklerle SEM ve ışık mikroskobu fotoğrafları çekilmiştir. Taksonlar arasında çeşitlilik arz eden özellikler korelasyon ve ayrım analizleri gibi çeşitli istatistiksel yöntemler kullanılarak değerlendirilmiştir. İncelenen özellikler arasında meyve yüzey desenlenmesi türlerin habitat tercihleri ile ilişkili iken epidermal hücrelere ait morfometrik özellikler ile kristal inklüzyonların çeşidi gibi yapısal özellikler cins seviyesinde önemli ayırt edici karakterlerdir.

Pericarp anatomy and surface micromorphology of some orchids in the Black Sea Region

Abstract

In this study, we have investigated the anatomy and ultrastructure of the pericarp to determine important characters of the fruits belonging to some Turkish orchidoid species, and to determine which features are related to ecological or habitat preferences. For the purpose, the samples belonging to 19 orchid taxon were collected in the Black Sea Region. SEM and light microscopy photographs were taken with the standard techniques. Variations among taxa were evaluated using various statistical methods such as correlation and discrimination analysis. Among the investigated characteristics, fruit surface ornamentation is related to habitat preferences of the species while morphometric properties of epidermal cells and structural features such as the type of crystal inclusions are important characters at the genus level.
