The global climate change recorded over recent years may prompt changes in phenological events. The present study sought to analyse the varying impact of changes in weather conditions at different times of the year on woody-plant flowering, by analysing recent trends in airborne count for 3 pollen types abundant in Galicia belonging to the Fagales order: Alnus, which flowers in early winter; Be...

Bu çalışmada seleksiyon çalışmaları ile öne çıkan 17 kestane (Castanea sativa Mill.) çeşit/genotip ülkemizde yetiştiriciliği yaygınlaşan iki hibrit x Castanea crenata) çeşit olmak üzere toplam 19 çeşit/genotipte erkek çiçek yapıları incelenmiş ve stamen tipi belirlenmiştir. Kestane çeşit/genotiplerin beşinin stamensiz, birinin kısa stamenli, dördünün orta boyda stamenli dokuzunun uzun olduğu Çe...

Introduction American chestnut (Castanea dentata (Marsh.) Borkh. once occurred over much of the eastern deciduous forests of North America (Russell, 1987), with a natural range exceeding 800,000 km (Braun, 1950) (Figure 1). Castanea dentata was a dominant tree species throughout much of its range, comprising between 25-50% of the canopy (Braun, 1950; Foster et al., 2002; Russell, 1987; Stephens...

The most dangerous pathogen affecting the production of chestnuts is Phytophthora cinnamomi a hemibiotrophic that causes root rot, also known as ink disease. Little information has been acquired in chestnut on the molecular defense strategies against this pathogen. The expression of eight candidate genes potentially involved in the defense to P. cinnamomi was quantified by digital PCR in Castan...

Sixty taxa (59 species and 1 variety) of lichenized fungi are reported from a chestnut grove in Livari. The majority of them (55 species and 1 variety) occurred on Castanea sativa. The recently described Xylographa soralifera is new to the Balkan Peninsula. The lichenicolous fungus Monodictys epilepraria growing on Lepraria rigidula is new to Montenegro. The lichen mycota is compared with simil...
