Abstract
Objective: The aim of this study is to determine the responses of some rice varieties in terms of the effects of Fe-EDDHA and lime on total chlorophyll and carotenoid content in leaves.
Materials and Methods: In this study, 5 different rice varieties were used. These varieties are: Biga İncisi, Osmancık-97, Hamzadere, Ronaldo and Edirne rice varieties. A nutrient solution containing Fe-EDDHA at 0 and 45 µM Fe concentrations in 2 different lime doses (0 % and 4 %) was given to rice plants grown in pots filled with sand. The experiment was conducted with 3 replications according to a 5 × 2 × 2 factorial trial design.
Results: The highest increase in total chlorophyll synthesis with iron application was detected in Edirne variety in lime-free sand media, and Hamzadere variety in lime-added sand media. In terms of average total chlorophyll content values in fresh leaves, paddy varieties were listed as Osmancık-97 > Biga İncisi > Ronaldo> Hamzadere > Edirne. In terms of carotenoid content in fresh leaves, rice varieties were listed as Osmancık-97> Biga İncisi > Ronaldo > Hamzadere > Edirne.
Conclusion: The rate of increase in carotenoid content in fresh leaves of Edirne variety was found to be the least in the application of nutrient solution containing Fe-EDDHA to lime-added sand media.
