Utilizing Some of Screening Methots in Order to Determine of Tolerance of Salt Stress in the Melon (Cucumis melo L.)

چکیده
In order to determine the genotypical differences and basic selection parameters for salt tolerance 36 melon genotypes were grown in hydroponics culture. When seedlings reached to 4-5 leaf stages 150 mM NaCl was applied to them. 14 days after salt application, young plants were harvested from control and salt treated groups. The fresh weight of green parts of young plants and the amount of some ions (Na , K and Cl ) were determined. It was found that there were differences among melon + + genotypes in terms of salt tolerance and this tolerance had a relationship either with the accumulation Na and Cl ions or not uptaking them at all. On the other hand ‘plant stress index value (PSI) (%)’ was found as an effective parameter for the determination of salt tolerance in melons.

Cucumis melo L. is one of the most economically important horticultural crops worldwide. However, low plant regeneration frequency of this plant during genetic transformation is the major hurdle for applying biotechnological approaches. Hence, this study aimed to evaluate the effect of 6-benzyladenine (BA), cefotaxime (CTX), kanamycin (KAN), and indole-3-acetic acid (IAA) on the regenerati...

In order to investigate the effect of palm leaf biochar on some characteristics of Cucumis melo L. under drought stress, a split plot experiment was conducted in a completely randomized block design with three replications for two consecutive years. The main plot was irrigation level (60, 85, and 100% water requirement) and subplot was biochar in four levels (0, 0.18, 0.24, and 0.36 kg/m2). Res...
متن کاملMolecular Cloning, Characterization, and Expression of Cuc m 2, a Major Allergen in Cucumis melo
Background: Several studies reported the clinical features of IgE-mediated hypersensitivity after ingestion of melon. Melon allergy is a common IgE-mediated fruit allergy in Iran. This prompted us to investigate immunochemical and molecular properties of the major allergen in melon fruit, to compare the IgE-binding capacity of the natural protein with the recombinant allergen, and to determine ...
