Abstract:

A theoretical framework for comprehending how tropical forests preserve their tree variety is provided by the Janzen-Connell hypothesis. According to the hypothesis, natural enemies, like herbivores and fungal pathogens, help plant species coexist by attacking their hosts more frequently when they are present in large numbers or when they are situated adjacent to mature conspecific trees. In order to better understand the overall ecology and the tree composition of forests, it is important to look at the association of trees with such plant enemies. This study examines the significance of fungal interactions with plants, particularly at the level of seeds, to better understand how fungi may impact important stages of recruitment and, as a result, regeneration of plant species. Knowledge of seed characteristics and the make-up of fungal communities linked to seeds must be combined in order to understand the mechanisms causing fungal colonisation.
