Pollen Morphology Of The Genus Fritillaria L. (Liliaceae) In Turkey, Mehtap Tekşen, Zeki̇ Aytaç, Nur Münevver Pinar Jan 2010

Pollen Morphology Of The Genus Fritillaria L. (Liliaceae) In Turkey, Mehtap Tekşen, Zeki̇ Aytaç, Nur Münevver Pinar

Turkish Journal of Botany

Pollen grains of 39 taxa of the genus Fritillaria L. in Turkey were examined by light and scanning electron microscopy. Detailed pollen morphological characteristics are given for these taxa. Our investigation shows that the sculpturing of the exine provides valuable characters for separating species. In particular, sculpturing of the exine at the proximal face turned out to be taxonomically important. Six types of ornamentation were determined: reticulate, reticulate-perforate, suprareticulate, rugulate-reticulate, psilate-perforate, and perforate. On the basis of exine sculpturing, the sulcus membrane, and the apex sulcus, 5 main pollen types are recognised.

The Effects Of Gamma Irradiation On The Pollen Size Of Gossypium Hirsutum L., Çi̇ğdem Savaşkan Jan 2002

The Effects Of Gamma Irradiation On The Pollen Size Of Gossypium Hirsutum L., Çi̇ğdem Savaşkan

Turkish Journal of Botany

Gossypium hirsutum L. (cotton) is cultivated widely in the south of Turkey. In this study, seeds of the cotton cultivar Çukurova 1518 were irradiated with gamma at 50, 100, 200, 300 and 400 Gray doses in a Co^{60} source. The size of morphologically normal pollen grains was measured in generation M_1 and found to be 120.35 µm in the control group, while this value was different in the irradiated groups. However, there was no significant difference in the size of pollen grains of normal morphology and shape between the irradiated and control pollens.
