Estimation of physiological traits of tomato using thermography technique and NDVI sensor

The aim of this study are to determine the water stress level using the values obtained from the Normalized Difference Vegetation Index (NDVI) sensor and the Crop Water Stress Index (CWSI) and also relationships among some physiological traits (stomatal conductance, relative leaf water content, leaf water potential, chlorophyll) of plant and CWSI/NDVI. The study was conducted in ？anakkale province in 2017 investigated four different irrigation treatments (100%, 75%, 50% and 25%). As a result of the study, both remote sensing indices gave important responses to water stress. In this case, it can be said that the water stress of the tomato can be determined successfully by using both indices. The results indicated that physiological measurements that are difficult to measure, time consuming and damaging to the plant can be estimated with high accuracy by combined use of CWSI and NDVI indices
