POROMETRIC ANALYSIS ON Crambe abysinica Hochst UNDER DROUGHT CONDITIONS

Abstract

The stomatal behavior of plants when subjected to periods of drought can be an important factor in the process of adaptation to such conditions. Porometric readings (transpiration and diffusion resistance) may have special significance for selecting more drought-tolerant or resistant plants. In this article, the porometric analysis of four experiments is discussed. It was observed that the diffusion resistance of crambi leaves increased as the total water potential in the soil decreased, while transpiration behaved in the opposite direction. This article also presents an analytical method to examine porometry data with physiological foundations and with the capacity to answer questions about the behavior of genotypes and their discrimination based on probabilistic assertions.
