In Vitro Pollen Germination And Pollen Tube Characteristics In Tetraploid Red Clover (Trifolium Pratense L., H. Nurhan Büyükkartal
In Vitro Pollen Germination And Pollen Tube Characteristics In Tetraploid Red Clover (Trifolium Pratense L., H. Nurhan Büyükkartal
Turkish Journal of Botany
The morphological characteristics, fertility and in vitro germination of natural tetraploid red clover (Trifolium pratense L.) pollen were examined as well as the characteristics of pollen tubes and callose formation. Pollen grains of red clover are tricolporate and usually the germination of pollen is monosphonic. Among the pollen tubes that were formed under in vitro conditions, in addition to those that went through the normal growth process, poorly or non-grown pollen tubes were also observed. In addition, some abnormalities in the form of callose deposition were observed in the pollen tubes.

Turkish Journal of Botany
The microfungal flora of field soils irrigated by the South-eastern Anatolia Project (GAP: Güneydoğu Anadolu Projesi) in Harran Plain were investigated in terms of quality and quantity, using the soil dilution plate and soil washing methods. A total of 1690 microfungi were isolated from 105 soil samples. With the identification of these isolates, 109 species plus 16 different sterile fungi were identified. Sixty-two of these taxa were isolated through the soil dilution plate method, seven through the soil washing method, and 40 through both methods. The results indicate that ten of these species belong to Mucorales, four to Sphaeriales, one …
In Vitro Clonal Propagation Of A Multipurpose Tree, Ziziphus Spina-Christi (L.) Desf., C. Sudhersan, J. Hussain
In Vitro Clonal Propagation Of A Multipurpose Tree, Ziziphus Spina-Christi (L.) Desf., C. Sudhersan, J. Hussain
Turkish Journal of Botany
A simple and efficient protocol for the clonal micropropagation of Ziziphus spina-christi (L.) Desf., a multipurpose native tree species highly adapted to the harsh environmental conditions of Kuwait, has been established using shoot tips and stem nodal segments as explants. The explants were cultured on Murashige and Skoog (MS) basal medium with and without growth regulators. The nodal segments and shoot tips isolated from the primary cultures were cultured on hormone-free MS media containing 100 mg/l myo-Inositol, 150 mg/l glutamine and 2.5% sucrose for plant growth and elongation. Shoots for multiplication were maintained on MS media with low concentrations of …

Turkish Journal of Botany
In this study the aspartate aminotransferase (AAT, E.C. 2.6.1.1), phosphoglucomutase (PGM, E.C. 5.4.2.2) and phosphoglucose isomerase (PGI, E.C. 5.3.1.9) isozyme patterns of nine different diploid and tetraploid wild wheat species belonging to the Aegilops L. and Triticum L. genera were analysed electrophoretically, using horizontal starch gel and non-denaturating polyacrylamide gel (only for AAT). All species were found to have three AAT isozyme zones (except for the AAT of Aegilops speltoides Tausch on starch gel) on both gels. While the migration distances of AAT-1 isozyme were similar, the AAT-2 and AAT-3 band patterns were different on both gels. A single PGI …

Isoenzyme Variation Of Esterase And Acid Phosphatase And Genetic Affinities Among Dasypyrum Villosum (L.) P.Candargy, Elytrigia Repens (L.) Nevski And Elymus Caninus (L.) L., Georgi Borisov Angelov
Turkish Journal of Botany
Polyacrylamide gel electrophoresis was employed to study the isoenzyme variation of esterase and acid phosphatase in natural populations of Dasypyrum villosum (L.) P.Candargy, Elytrigia repens (L.) Nevski and Elymus caninus (L.) L. Four similarity indices (SI, S, D, I_h) were calculated in an attempt to evaluate quantitatively genetic affinities among the species examined. Considering index D, the species D. villosum proved to be equally distant (D = 0.17 in both cases) from the species pair Et. repens and El. caninus. The nearly twice lower value of D for the comparison between Et. repens and El. caninus is an indication of …

A Study On The Occurrence Of Merismopedia Meyen (Cyanobacteria) Populations On The Littoral Sediments Of İzmit Bay (Turkey), Yelda Aktan, Güler Aykulu
Turkish Journal of Botany
In a previous study of epipelic diatoms on the littoral sediments of İzmit Bay (Marmara Sea, Turkey), which was carried out from March 1999 to September 2000, it was found that two Merismopedia Meyen species (Cyanobacteria) occurred frequently. In the present study, the seasonal variations of density and biomass of the Merismopedia species, which were dominant at certain times in the epipelic algal flora on the littoral sediments of İzmit Bay, were investigated. In addition, some physical and chemical parameters were measured. One of the species, Merismopedia glauca (Ehrenb.) Nägeli, was dominant in terms of cell numbers and frequency while …

Planktonic Diatom (Bacillariophyceae) Flora Of Sultan Sazlığı Marshes (Kayseri), Aydin Akbulut
Turkish Journal of Botany
This paper describes the planktonic diatom flora of the Sultan Sazlığı marshes, Kayseri. Samples were collected systematically from the marshes over a period of 1.5 years from three stations. The diatom flora of Sultan Sazlığı is rich in terms of species and varieties, which are similar to those from many parts of Turkey. A total of 75 taxa of diatoms were identified. The diversity of species at freshwater stations was higher, than that of the brackish water station. Genera such as Fragilaria Lyngb., Navicula, Gomphonema Ehrenb., Nitzschia Hassall, Epithemia Bréb. ex Kütz. were dominant in species numbers.
