Analysis of Physiological and Biochemical Characteristics of Local Soybean Varieties which were Artificially Damaged with Phytopathogenic Fungi

Abstract

According to the analysis of the results of the amount of chlorophyll "a" and "b" in the leaves of local soybean varieties under the influence of phytopathogenic micromycetes during the budding period was found that the chlorophyll "a" and chlorophyll "b" index of all soybean varieties decreased compared to the control. This situation indicates that the amount of chlorophyll "a" and chlorophyll "b" in the leaves of soybean plants is related to the presence of phytopathogenic micromycetes. When studying the effect of micromycetes F. oxysporum on the content of chlorophyll "b" in soybean leaves, the least effect was found in varieties Tomaris and Genetik-1 (respectively, the difference from the control = -9.3 and -9.6), and the local variety Sochilmas had the strongest influence (respectively, it showed that the difference from the control = -56.6 and -61.1). When studying the effect of micromycetes A. alternata on the amount of chlorophyll "b" in soybean plant leaves, the variety Genetik-1 had the least effect (respectively, the difference from Control = -15.4 and -14.3), and the strongest effect was on varieties Nafis and Sochilmas (respectively differences from control = -41.6 and -38.2).
