Pollen Morphology of Some Turkish Crocus L. (iridaceae) Species
The genus Crocus L. (Iridaceae) comprises about 80 species distributed mainly in the Mediterranean region. It is widely dispersed in Turkey; at present about 67 taxa (including subspecies and varieties) are recognized there (Mathew, 1984, 1988, 1995, 2000; Kerndorff and Pasche, 2003, 2004). The Turkish Crocus species have received attention by several workers, who have concentrated mainly on mo...
متن کاملEvidence of natural hybridization between Aegilops geniculata and wheat under field conditions in Central Spain.
This study deals with hybrids between Aegilops geniculata and bread wheat, Triticum aestivum L., detected in two Ae. geniculata populations in the "Meseta Central", Spain's central plateau where wheat is a major crop. Morphological traits and pentaploid chromosome numbers were used to identify hybrids in 2004 and 2005. The frequency of hybridization under natural conditions was calculated for o...
متن کاملHybrids and amphiploids of Aegilops ovata L. with Secale cereale L.: production, morphology and fertility.
Hybrids (2n = 3x = 21) between Aegilops ovata and Secale cereale were produced via embryo rescue. Most hybrid morphological traits were intremediate between parents, the plants grew vigorously but were completely sterile. The average frequency of chromosome associations at metaphase I was 19.57-20.19 univalents and 0.40-0.86 rod bivalents. The fertility of the hybrids was restored by doubling t...
متن کاملJointed Goatgrass (Aegilops cylindrica) by Imidazolinone-Resistant Wheat Hybridization under Field Conditions
Gene flow between jointed goatgrass and winter wheat is a concern because transfer of herbicide-resistance genes from imidazolinone-resistant (IR) winter wheat cultivars to jointed goatgrass could restrict weed-management options for this serious weed of winter wheat cropping systems. The objectives of this study were (1) to investigate the frequency of interspecific hybridization between IR wh...
متن کاملHybridization and the species problem in conservation
Most biologists recognize the “species phenomenon” as a real pattern in nature: Biodiversity is characterized by discontinuities between recognizable groups classified as species. Many conservation laws focus on preventing species extinction. However, species are not fixed. Discontinuities evolve gradually and sometimes disappear. Exactly how to define particular species is not always obvious. ...
