GERMINAÇÃO CARPOGÊNICA DE SCLEROTINIA SCLEROTIORUM EM SOLOS COM DIFERENTES HISTÓRICOS DE PLANTIO

Abstract

This study focuses on attempting to reproduce the ideal conditions for carpogenic germination of Sclerotinia sclerotiorum, a notable agricultural pathogen, in a BOD chamber. The research was meticulous in creating a controlled environment, however, the results did not match the expectations. The high humidity in the BOD chamber prevented the formation of apothecia, fundamental structures for the sexual reproduction of the fungus. This result underlines the delicacy and complexity of the carpogenic germination process of S. sclerotiorum. It became evident that the precise balance between air and soil moisture is crucial for the development of apothecia. In addition, the excess humidity may have negatively impacted the sclerotia, contributing to the lack of success in germination. This study highlights the intrinsic sensitivity of the process and the significant implications for future investigations. Understanding these challenges is vital for advances in pathogen biology and for enhancing management strategies in real agricultural environments. Therefore, this study highlights the need for precise considerations of environmental conditions when designing experiments aimed at understanding the carpogenic germination of S. sclerotiorum.
