Oak mistletoe / Silver carbonate solution for injection 1ml ampoules

The paper presents the distribution of localities of seven tree taxa, identified as new hosts of mistletoe in Poland, in the city of Toruń. Particular attention was paid to the description of a site with mistletoe on an oak identified as Quercus x rosacea. The reason for this is that native oaks are rare hosts of mistletoe in Central and Eastern Europe and this is the first finding of such a host–parasite association in Poland. The occurrence of all eight host species at 14 sites was compared with the distribution and description of localities and morphological characteristics of both host–mistletoe association components presented in the botanical, ecological and forestry literature.

Abstract This study delves into the impact of seasonal variations on the diversity of endophytic fungi inhabiting the foliage of Grevillea robusta trees along highways in Hawassa City, Ethiopia. With 765 fungal isolates categorized into 73 distinct morphotaxa, 90.41% were identified across eight known genera, leaving 9.58% unidentified. Notably, Phoma and Pestalotiopsis emerged as the most diverse genera, presenting 13 and 11 morphotaxa respectively, while Alternaria and Xylaria showed lower diversity with 3 and 2 morphotaxa each. The research unveiled heightened fungal counts and diversity in trees situated in more polluted environments, leaves sampled during dry seasons, those exhibiting signs of disease, lower leaf sections, and midrib samples. These findings underscore the rich assortment of endophytic fungi associated with Grevillea robusta leaves within roadside plantations in Hawassa City, emphasizing the need for further exploration of this fungal community's dynamics. Understanding the pivotal role of these endophytic fungi in tree health, ecosystem resilience, and potential applications in agriculture, forestry, and biotechnology remains imperative.
