Use of thermal imaging and spectral data to detect water stress in green bean

It is important to detect water stress before physiological activities of plants permanently change. Otherwise production might decrease dramatically. Many researches showed that thermal imaging or spectral data, collected from plant leaves or canopy, have potential to determine plant water stress. In this study, our objective was to determine water stress on green beans (Phaseolus vulgaris L. cv. Gina) using both thermal imaging technique and spectral reflectance data. Bitkilerin fizyolojik aktivitelerindeki de�i�im kal�c� hale gelmeden �nce su stresini belirlemek �nemlidir. Bunun sonucunda ciddi oranda verim kayb� ya�anabilir. Bir�ok ara�t�rmac�, bitki ta� ve yapraklar�ndan toplanan termal ve spektral verilerin bitki su stresinin belirlenmesinde kullan�labilecek potansiyel ara�lar oldu�unu vurgulam��lard�r.
