dc.description.abstractIn this study, it was aimed to determine the water stress level of pepper plant by help of thermal indices and to determine the relationships among some physiological traits with these indices. An experiment consisting of four different irrigation applications (S100, S75, S50 and S25) was conducted in 2017 in Çanakkale. According to the results obtained from the study, thermal indices and all physiological traits were affected from the irrigation treatments. Crop Water Stress Index (CWSIe) determined empirically from the measurements of plant body with the help of thermal camera increased due to the decrease in irrigation water and Stomatal Conductance Index (IGe) has decreased as well. According to classification and regression tree analysis, arguably the use of CWSIe is enough to determine the time to start irrigation. In this case, the threshold value of the index is suitable as 0.42. According to the results of regression analysis for each growth period, significant correlations (p <0.001) were obtained among physiological traits with thermal indices. These relations increased after flowering period. As a result of the study, because of its success in discriminating water stress and ease of application, the use of indices obtained by thermal cameras which is one of the remote sensing techniques may be suggested for pepper plant. The study showed that the water stress in pepper plant has the potential to be determined quickly and accurately by using thermal images. © 2020, Centenary University. All rights reserved.
