Abstract

The growth and fluorescence parameters of chlorophyll in four CORN HYBRIDS including two sweet (K.S.C. 403 and K.S.C. 404) and two grain hybrids (S.C. 500 and S.C. 700) were evaluated in response to Fe and Zn nutrition in a NUTRIENT SOLUTION culture. This study was conducted in a randomized complete block design with a factorial arrangement with three replications at the Soilless Culture Research Center (SCRC). CORN HYBRIDS were exposed to two Fe levels (5 and 50 µM Fe in the form of FeEDTA) and two Zn levels (0 and 2 mM Zn in the form of ZnSO4). Increasing Fe concentration in the NUTRIENT SOLUTION increased F0, Fm, and Fv/Fm values by 48, 96, and 123%, respectively. The fluorescence parameters of chlorophyll were affected by corn hybrid and there were significant differences in F0 and Fv/Fm at 1% level and Fm at 5% probability level among the studied hybrids. IRON deficiency significantly (P<0.05) reduced the root dry weight of all the studied hybrids. ZINC deficiency resulted in a significant decrease in the root dry weight of H403 and H500 hybrids while no significant decrease was found in the root dry weight of the H404 and H700 hybrids under Zn condition. The results showed that CORN HYBRIDS varied significantly in their tolerance to Fe and Zn deficiency. Based on the results of plant growth and fluorescence parameters of chlorophyll, the studied grain CORN HYBRIDS were more tolerant to Fe and Zn deficiency conditions in comparison with sweet CORN HYBRIDS. It seems fluorescence parameters of chlorophyll might be suitable parameters to screen CORN HYBRIDS in their tolerance to Zn and particularly Fe deficiency condition.
