ABSTRACT. Eggplant is a major crop in Turkey, which produces more of this crop than all of Europe; consequently, germplasm resources are of concern for the country. Molecular characterization of eggplant genotypes collected from different geographical regions of Turkey was carried out using SSR and RAPD markers. With amplification of five SSR loci, the number of alleles per microsatellite locus ranged from 2 to 10, with a total of 24 alleles. The greatest number of alleles was found at the emf21H22 locus (10 alleles); followed by emh11O01 and emf21C11 as five and four alleles, respectively. The average num ber of alleles per locus was 4.8. Using 11 decamer RAPD primers, 100 bands were amplified, among which 29 were polymorphic. The number of bands per primer ranged from seven (OPH10, OPH19, OPH20, OPH03) to 14 (OPB07). Primer OPB07 was the most polymorphic, generating 64% polymorphic bands; the rest of the primers gave less than 50% polymorphism. UPGMA dendrograms were used to examine the genetic relatedness of the genotypes.

The experiment was conducted to evaluate the effets of various NO 3 /CI percentages on growth, nitrate accumulation and mineral absorption in carrot Daucus carota L. plants in a controlled enviroment. The experiment included two CI sources (KCI and CaCl 2 ) and five NO 3 /CI percentages at 100/0, 90/10, 80/20, 70/30, and 60/40 with total-N concentration of 400 mg NO 3 /kg soil in 100/0 treatment. The fresh and dry weights of shoots and storage roots, and the length and diameter of storage roots increased significantly more with mixed NO 3 /CI treatments and CI sources than with single NO 3 (100/0) treatment. Growth was enhanced up to the 80/20 NO 3 /CI treatments. With CI present in the treatments, the concentration of total-N unchanged and NO 3 decreased, and CI and K increased both of the CI sources. In KCI treatments, Na absorption decreased Calcium content significantly differed among the treatments. It was concluded that nitrogen fertilization provided with combined CI forms and NO 3 /CI percentages can enhance the quality of carrots and at the same time derease the N fertilizer input rate.
