Türkiye'de Yayılış Gösteren Bazı Sisymbrium L. (Brassicaceae) Taksonlarının Meyve ve Tohum Yapılarının Mikromorfolojik Açıdan İncelenmesi

Öz

Brassicaceae familyası ülkemizin en büyük kapalı tohumlu bitki ailelerinden biridir. Tıbbi, ekonomik ve gıda amaçlı yetiştirilen birçok üyesi bulunmaktadır. Bazı üyeler ise genetik çalışmalarda model canlı olarak kullanılmaktadır. Bu denli önemli bir familyanın ülkemizde yayılış gösteren taksonlarının araştırılması önem arz etmektedir. Bu araştırmada Türkiye’de yayılışı olan Sisymbrium L. cinsinin meyve ve tohum yapılarının morfolojik özellikleri incelenmiştir. 2010-2013 yılları arasında üç yıl süren saha çalışmaları sonucunda toplanılan 450 bitki örneği incelenerek herbaryum ziyaretleri neticesinde dokuz Sisymbrium türüne ait (Sisymbrium polyceratium, S. runcinatum, S. elatum, S. officinale, S. altissimum, S. septulatum, S. orientale, S irio ve S. loeselii) bulgular sunulmuştur. Çalışmada S. confertum Steven ex Turcz. türünün Türkiye’deki varlığı teyit edilemediğinden incelenememiştir. Ülkemizin cinse ait tek endemik türü olan 2015 yılında yayımlanan S. malatyanum Mutlu & Karakuş türü ise çalışmaya dahil edilememiştir. İncelenen dokuz Sisymbrium türüne ait meyve ve tohum yüzeyi mikromorfolojileri elektron mikroskobu (SEM) ile incelenmiş olup farklılık ve ayrımlar dikkate alınarak cinsin mikromorfolojik teşhis anahtarı oluşturulmuştur.

Micromorphological Investigation of Fruit and Seed Structures of Some Sisymbrium L. (Brassicaceae) Taxa Spreading in Turkey

Abstract

The Brassicaceae family is one of the largest Angiosperm families in our country. It has many members grown for medical, economic and food purposes. Some members are used as a living model in genetic studies. It is important to investigate the taxa of such an important family spreading in our country. In this research, the morphological characteristics of fruit and seed structures of the genus Sisymbrium L., which has spread in Turkey. 450 plant samples collected as a result of three years of field studies between 2010-2013 were examined and are presented as a result of the herbarium visitations belonging to nine Sisymbrium species (Sisymbrium polyceratium, S. runcinatum, S. elatum, S. officinale, S. altissimum, S. septulatum, S. orientale, S irio and S. loeselii) are presented. In the study, the presence of the S. confertum Steven ex Turcz genus in Turkey could not be examine because it could not be verifiable. S. malatyanum Mutlu & Karakuş species published in 2015, which is the only endemic species belonging to the genus of our country, could not be included in the study. Fruit and seed surface micromorphologies of nine Sisymbrium species were examined by electron microscopy (SEM) and the micromorphological diagnostic key of the genus was established taking into account the differences and distinctions.
