Pollen morphology of six Achillea L. sect. Achillea (Asteraceae) species in Turkey

Öz:

Bu çalışmada, Achillea L. cinsi Achillea seksiyonunun (Asteraceae) Türkiye’de yayılış gösteren 6 türü (9 takson) A. nobilis L. subsp. neilreichii (A.Kern.) Formánek, A. nobilis subsp. densissima (O.Schwarz ex Bässler) Hub.-Mor., A. nobilis subsp. sipylea (O.Schwarz) Bässler, A. nobilis subsp. kurdica Hub.-Mor., A. fi lipendulina Lam., A. clypeolata Sm., A. coarctata Poir., A. biebersteinii Afan. ve A. cappadocica Hausskn. & Bornm.’ya ait 48 örneğin polen morfolojisi ışık (LM) ve elektron mikroskobu kullanılarak (SEM) incelenmiştir. Polenler oblat-sferiodal, prolat-sferiodal, subprolat ve genellikle trikolporat bazen tetrakolporat hatta pentakolporatdır. Polen boyutlarının polar eksen ortalamaları 17,6-57,5 μm ve ekvatoral eksen ortalamaları 19,7-55,2 μm arasında değişmektedir. Şekli, meridional optik bölgede oval yada dairemsi ve polar optik bölgede trilobulat bazen tetralobulattır. Ekzin yapısı doubletektat ve ortalama kalınlığı 3-8,5 μm arasında değişmektedir. Polen ornementasyonları LM’de ekinat, SEM’de ekinat-mikroperforat ve ekinat-rugulatmikroperforatdır. Sonuç olarak, incelenen türlerin polen özellikleri hem türler arası hem de tür içi düzeyde önemli değişkenlikler göstermektedir.

Türkiye’deki altı Achillea L. cinsi, Achillea seksiyonu (Asteraceae) türünün polen morfolojisi

Öz:

Th e pollen morphology of 48 specimens of 6 species (9 taxa) of the genus Achillea L. sect. Achillea (Asteraceae), A. nobilis L. subsp. neilreichii (A.Kern.) Formánek, A. nobilis subsp. densissima (O.Schwarz ex Bässler) Hub.-Mor., A. nobilis subsp. sipylea (O.Schwarz) Bässler, A. nobilis subsp. kurdica Hub.-Mor., A. fi lipendulina Lam., A. clypeolata Sm., A. coarctata Poir., A. biebersteinii Afan., and A. cappadocica Hausskn. & Bornm. distributed in Turkey were investigated using light (LM) and scanning electron microscopy (SEM). Th e pollen grains were oblate-spheroidal, prolatespheroidal, subprolate and generally tricolporate, though at times tetracolporate or even pentacolporate. Th e size of the grains varied, ranging from 17.6 to 57.5 μm on the polar axis mean and from 19.7 to 55.2 μm on the equatorial axis mean. Th eir outline is oval, compressed oval, or circular in the meridional optical section and trilobulate or sometimes tetralobullate in the polar optical section. Th e structure of the exine is double tectate and mean exine thickness varied from 3 to 8.5 μm. Th e pollen ornamentations are echinate in LM and echinate-microperforate and echinate-rugulatemicroperforate in SEM. In conclusion, the species examined showed substantial variation in pollen characteristics, at both the interspecifi c and intraspecifi c levels.
