Genetic Diversity And Phylogenetic Relationships Of A Potential Cotton Collection For European Breeding Research, Elena Peláez Andérica, Felipe Rey Montero, Manuel López García, Juan Gil Ligero
Turkish Journal of Botany
An understanding of the genetic diversity of any plant collection is essential for initiating future plant breeding strategies. Throughout the cotton regions in Europe (mainly Greece and Spain), there is an expanding need for new yielding varieties with shorter crop cycles and high quality fiber. Although cotton is decisive to many rural economies, it is surprising that there is a lack of public information available regarding genetic diversity of European cotton varieties. Thus, we began an examination of variability heritage by evaluating a subset of 48 commercial and experimental cotton varieties (36 Gossypium hirsutum, 10 G. barbadense, 1 G. arboreum, …

Pollen Morphology Of Scaligeria Dc. (Apiaceae) In Turkey, Ayşe Baldemi̇r, Şenol Alan, Aydan Acar Şahi̇n, Mehmet Yavuz Paksoy, Nur Münevver Pinar
Turkish Journal of Botany
In this study, the pollen morphology of all Scaligeria DC. species distributed in Turkey were studied with light and scanning electron microscopy for the first time. The aim is to contribute to knowledge of the variation among seven Scaligeria species, which have taxonomic problems, based on pollen morphological characteristics by population analysis. The pollen is radially symmetrical, isopolar, and tricolporate in all examined species. Pollen grains are prolate and subprolate with the polar axes ranging from 18.4 to 37 μm and the equatorial axes from 9.8 to 30 μm. Their polar shapes are triangular, triangular to subcircular, circular to subcircular, …
