Micromorphological comparison of Nepeta viscida, N. nuda subsp. nuda and their putative hybrids N. x tmolea

Abstract

In this study, two Nepeta species, Nepeta viscida, N. nuda subsp. nuda, and their putative hybrids N. x tmolea were investigated for their trichome structure and density.  For this purpose, fresh or herbarium specimens were used.  SEM photographs were taken with the standard techniques in Balıkesir University.  While N. x tmolea individuals are similar to N. nuda subsp. nuda in some respects (for example, absence long glandular trichomes on the stem, the absence of glandular hairs on the corolla), it shows some transition between N. viscida and N. nuda subp. nuda in some respects (for example, while the corolla of N. viscida does not contain long glandular hair, presence in a high density in N. nuda subsp. nuda and low density in N. x tmolea individuals).

Nepeta viscida, N. nuda subsp. nuda ve muhtemel hibritleri N. x tmolea’nın mikromorfolojik olarak karşılaştırılması

Abstract

Bu çalışmada, iki Nepeta türü, Nepeta viscida, N. nuda subsp. nuda ve bunların muhtemel hibritleri N. x tmolea, tüy yapıları ve yoğunlukları açısından incelenmiştir.  Bu amaçla taze veya herbaryum örnekleri kullanılmıştır.  Tüy tipleri ve dağılışları istatistiki olarak değerlendirilmiştir.  N. x tmolea bireyleri bazı açıdan N. nuda subsp. nuda’ya benzerlik gösterirken (Örneğin; gövdede uzun salgı tüyü olmaması, korollada sapsız salgı tüylerinin (peltat) bulunması), bazı açıdan ise N. viscida ile N. nuda subp. nuda arasında geçiş özelliği göstermektedir (Örneğin; N. viscida korollası uzun salgı tüyü içermezken, N. nuda subsp. nuda türünde yoğun şekilde bulunması ve N. x tmolea bireylerinde düşük yoğunlukta olması).
