Internal Reflectance Modelling of Hordeum vulgare Leaves During Drying

Abstract EN

Spectral reflectance, or indexes that characterize spectral reflectance at concrete wavelength, is commonly used as an indicator of plant stress, or its photosynthetic apparatus status.

In this paper, new leaf optical model is presented.

Within this paper, experimental determination of surface and internal reflectance of Spring barley leaves and mathematical-physical modelling of internal reflectance were performed.

It was proven that a new proposed theoretical model and the experimental spectra of internal reflectance are strongly correlated.

It can be concluded that the total reflectance is not a function of epidermis condition, but it testifies about overall functional condition of Spring barley leaves.
