| Research Abstract |
The objective of this study was to estimate the plant water stress in the community, not in a single plant only, via the transpiration status in wheat.
As the plant canopy temperature reflects the transpiration status, it was estimated by using an infrared thermograph in several wheat genotypes developed in Syria and Japan. The canopy temperature of a Japanese genotype which had the smallest seed yield show the highest between the 35 and 57 days after sowing. This indicates that this genotype would suffer from plant water stress during this period, which might result in the largest yield loss through preventing proper panicle development. This study showed the usefulness of infrared thermograph to capture the genotypic differences on canopy temperature in wheat.
