<i>Fusicoccum</i> canker of highbush blueberry was first detected in 1973 in Poland. The diseases appeared on the shoots of variety Jersey in the collection of the Department of Pomology, Agricultural University, Warsaw-Ursyn6w. The disease was caused by the fungus <i>Godronia cassandrae</i> f. <i>vaccinii</i> {Peck.) Groves. The conidial stage is known as <i>Topospora myrtilli</i> (Felfch.) Boermema syn. <i>Fusicoccum putrefaciens</i> Shear.

Some histological changes were observed in blueberry stems infected by the fungus <i>G.cassandrae</i>. Dead cells of subepidermal collenchyma and cortical parenchyma filled with brown flocculent deposits were seen in the lesion areas. Pycnidia characteristic for the conidial stage of the fungus (<i>Topospora myrtilli</i>) were found in the collenchyma layer. The diseased tissues were found to be separated from the healthy ones by a layer of cork cells which was initiated under the epidermis and ended under the pericycle. Beneath this cork layer lamellar collenchyma and collenchyma-like phelloderma formed. Similar histopathological changes were observed in blueberry stems infected by seven other fungi.

W latach 2017–2018 prowadzono badania dotyczące wy-stępowania chorób powodowanych przez grzyby na czterech plantacjach borówki wysokiej zlo-kalizowanych w centralnej Polsce. Celem badańbyła izolacja i identyfikacja patogenów z pora-żonych organów krzewów borówki wysokiej. W badanym materiale roślinnym zidentyfikowano cztery gatunki grzybów. Na wszystkich lustrowa-nych plantacjach obserwowano Botrytis cinerea, Godronia cassandrae i Phomopsis vaccinii, a tyl-ko na jednej plantacji zidentyfikowano Valdensia heterodoxa. Grzyby identyfikowano na podstawie oznak etiologicznych obecnych na porażonych organach roślin, przy użyciu klasycznych metod. W ramach badań oceniono skuteczność siedmiu fungicydów w zwalczaniu choroby szara pleśńborówki wysokiej. Do badań wykorzystano za-równo preparaty powszechnie polecane w ochro-nie borówki wysokiej przed szarą pleśnią, jak i fungicydy dopuszczone do ochrony przed tą cho-robą upraw innych roślin jagodowych (truskawka i malina). Fungicydy Luna Experience 400 SC i Prolectus 50 WG mogą być rozważane jako uzu-pełnienie listy środków zalecanych do zwalczania choroby szara pleśń na plantacjach borówki wy-sokiej.

Anthocyanins are widely distributed secondary metabolites that play an essential role in skin pigmentation of many plant organs and microorganisms. Anthocyanins have been associated with a wide range of biological and pharmacological properties. They are also effective agents in the prevention and treatment of many chronic diseases. Berries are particularly abundant in these compounds; therefore, their dietary intake has health-promoting effects. The aim of this study was to identify and determine the anthocyanin content in selected species and cultivars of berry fruits, such as raspberry, blackberry, red currant, blackcurrant, and highbush blueberry, widely consumed by Europeans. The concentrations of anthocyanins were determined by HPLC, identifying individual compounds: cyanidin-3-O-glucoside, pelargonidin-3-O-glucoside, delphinidin-3-O-glucoside, delphinidin-3-O-rutinoside, cyanidin-3-O-rutinoside, delphinidin-3-O-galactoside, cyanidin-3-O-galactoside, and malvidin-3-O-galactoside. The experimental data showed that the selected species and cultivars of berry fruits differ significantly in the contents of anthocyanins. Among all species tested, blackberry and blackcurrant were characterized significantly by the highest content of anthocyanins (sum), while the lowest content was found in red currant fruits. Additionally, the content of individual anthocyanin compounds in particular species and cultivars was also different. Considering the high content of anthocyanins and their potential positive impact on human health and protection against disease, berries should be part of healthy nutrition.
