    Determination of Morphological and Pomological Characteristics of Pomegranate (Punica Granatum L.) Genotypes Grown in Diyarbakır
    (2019) Çiçek, Mehmet; Pakyurek, Mine; Çelik, Ferit
    The aim of this study was to determine the pomological and morphological characteristics of pomegranate genotypes grown in Çermik and Dicle districts of Diyarbakır province. As a result of the study carried out on 10genotypes; fruit weights were found between 198.8 and 366.0 g, seed hardness of the fruit was medium-hard ineight genotypes, hard in two genotypes, aril yield ranged from 58.1 to 70.0% and fruit juice volume was between63.9 and 135.7 ml. The upper peel color was purple in four genotypes, pink-red in two genotypes, orange-red inone genotype and orange in three genotypes. The bottom peel color is orange-red in seven genotypes and orangein three genotypes. Aril color was dark purple in three genotypes, purple in two genotypes, medium red in twogenotypes and pink-red in three genotypes. The acid content was found to be between 0.65 and 1.21% and theamount of total soluable solid (TSS) varied between 15.0 and 21.0%. It was concluded that all 10 genotypes werepromising and these genotypes showed superior characteristics.

    Genetic Diversity Among Some Asparagus Species Using Rdna Its, Cpdna Trnl Intron Sequence and Screening for Antioxidant Activity
    (Hard, 2019) Altintas, Serdar; Pakyurek, Mine; Sensoy, Suat; Erez, M. Emre; Inal, Behcet
    Three species of genus Asparagus native to Lake Van Basin of Turkey were analyzed using internal transcribed spacer (ITS) and cpDNA trnL intron sequence. Furthermore, these species were screened for their antioxidant activity and total phenolic and flavonoid contents. Phylogenetic analysis based on ITS data revealed two clades: the first clade consisted of Asparagus persicus and Asparagus officinalis, and clade II consisted of Asparagus palaestinus. Similarly, phylogenetic analysis using trnL intron sequence revealed two clades. In term of total phenolic content and total flavonoid content, the highest value were measured for acetone extract of Asparagus persicus sample No. 2 and Asparagus persicus sample No. 6, respectively. The highest antioxidant activity using FRAP assay was found for Asparagus persicus sample No. 3. We concluded that these species could be useful for increasing genetic diversity among cultivated species and for breeding.
