Effects of drought stress on chlorophyll content Changes of maize cultivars under field conditions
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 8
Abstract
In order to assess the effects of drought stress on chlorophyll content in maize cultivars in four replications and with two irrigation and dry farming conditions in a randomized complete block design in the 2010- 2011 agricultural years in Ardabil region was carried out. To calculate the amount of stress tolerance of genotypes has been used of Fernandez stress tolerance indexes. And the chlorophyll content of leaves with the CCI-200 device was measured. The results showed that stress-resistant genotypes with higher potential yield and chlorophyll content were more than half resistant cultivars. According to the results of genotypes SINGLE CROSS 302 and Single cross 647 have a highest chlorophyll index and the amount of yield and the most resistant genotypes to the drought.
