Netradiční ovocné dřeviny a jejich ochrana
Korbelová, Pavla
Main topic of this master thesis evaluates deseases and disorders on the school farm of Mendel University Brno. Following fruit trees were closely monitored between May and October 2015: Actinidia chinensis, peach, dogwood, pear, mountain ash, quince, almond, medlar, mulberry, juneberry, sea buckthorn and Rosa villosa. The most serious disease fire blight was not observerd at all, probably because all quince orchards nearby were chopped down several years ago. However there were other serious diseases observerd such as fading of annual shoot of sea buckthorn and mildew on juneberry. Amelanchier lamarcki species were affected more with mildew than A. alnifolia species. There were abiotic disorder observed on mountain ash due to lack of minerals, together with ringfleck mosaic. The least important disease symptoms were observed on peach, dogwood, pear, almond, mountain ash, quince a Rosa villosa. Medlar and mulberry were free from all diseases. All in all, the most important is to keep the right cultivation technique and early removal of infected and cracked branches. Juneberry also requires chemical treatment.
