Abstract

In this study, determinability of by wavelengths chosen from derivate graphics of reflectance data obtained by the visible near infrared spectroscopic method (VNIR) of Zn deficiency in cherry trees was investigated. The research was carried out in the three different locations in Isparta Province. With this aim, 15 different orchards was chosen had normal and Zn deficiency in the different levels in every location and the total 60 leaf samples were taken from four different trees of each orchard. Spectral reflectance of the leaves were measured by the ASD Field Spec Hand Held spektroradyometer and plant probe, derivate curves were formed and Zn contents of the leaves were determined in laboratory. Spectral derivate curves and Zn levels were evaluates by the method of stepwise multiple linear regression analysis. In the result, it was obtained that usable of 465, 520, 570, 600, 620, 650, 720, 730, 800 and 850 nm wavelengths in the determinate of Zn levelfrom breaking curve determining in the derivate graphics of spectral data

Özet

Bu çalışmada kiraz ağaçlarında oluşan Zn noksanlığının görünür yakın kızılötesi (VNIR) spektroskopik yöntem ile elde edilen yansıma verilerinin türev grafiklerinden seçilen dalga boyları ile belirlenebilirliği çalışılmıştır. Çalışma Isparta ilinde 3 farklı lokasyondan alınan örneklerde yürütülmüştür. Bu amaçla her lokasyonda sağlıklı bitkiler ile birlikte farklı şiddetlerde Zn noksanlığının karakteristik özelliklerini gösteren 15 farklı bahçe seçilmiş, her bahçeden 4 farklı ağaç olmak üzere toplam 60 bitkiden yaprak örnekleri alınmıştır. ASD FieldSpec HandHeld spektroradyometre cihazı-bitki probu (plantprobe) aparatı kullanılarak yaprakların spektral yansımaları ölçülmüş, türev eğrileri oluşturulmuş ve yapraklarda Zn besin elementi içerikleri laboratuvar analizleri ile belirlenmiştir. Spektral türev eğrileri ile Zn elementi seviyeleri stepwise çoklu linear regresyon analiz yöntemiyle değerlendirilmiştir. Araştırma sonucunda spektral verilerin türev grafiklerinde belirlenen kırılmalardan Zn seviyesini belirlemede 465, 520, 570, 600, 620, 650, 720, 730, 800 ve 850 nm dalga boylarının kullanılabildiği sonucuna varılmıştır.
