    Effect of Salinity Stress on Nutrient Composition of Field Pea Genotypes (Pisum sativum. sp. arvense L.)
    (MEDWELL ONLINE, 2008) Yildinim, Buenyamin; Yasar, Fikret; Terzioglu, Oemer; Tamkoc, Ahmet; Tuerkoezue, Didem
    The present study aimed to investigate the effect of different days (0, 7 and 15th days) and salt applications (salty and saltness) on nutrient element compositions of root, shoot and leaf organs of I I field pea genotypes (which are nominate pea) and 2 pea cultivars. For this aim, the data were analyzed using three-way-ANOVA (genotypes, salt application and time). In this study determining, the effects of salt stress on nutrient element compositions of these organs, although the effects of salt application, salt by variety and salt by day interactions on Cu element in root were only found to be non-significant, genotypes, salt application, days and their interactions with 2 and 3 degree for other elements were found to be significant. In root and shoot organs, salt application increased significantly Ca, Mg and Zn amounts, but other minerals decreased compared to control group. The application in leaf increased Ca and Mg, whereas others reduced.

    Variations in Response to Salt Stress among Field Pea Genotypes (Pisum sativum sp.arvense L.)
    (MEDWELL ONLINE, 2008) Yildirim, Buenyamin; Yasar, Fikret; Oezpay, Taylan; Tuerkoezue, Didem; Terziodlu, Oemer; Tamkoc, Ahmet
    This Study examined the responses to salt stress in 11 pea genotypes and two pea cultivars. Pea genotypes were selected from among wild pea and white flowered pea cross-breed varieties from different regions in Anatolia. In general, root fresh weight (fw) shoot fw, leaf fw, leaf number and chlorophyll contents were found to decrease with increases in salinity, whereas root and leaf MDA ratios increased with increases in salinity. Genotypes 1 (10431), 9 (101917) and 10 (1103220) were found to be the most salt-tolerant. Genotypes 6 (110121) and 7 (B-6) were found to be the most sensitive.
