@article{BOROVINOVA_2006, title={SUSCEPTIBILITY OF APPLE CULTIVARS TO BOTRYOSPHAERIA OBTUSA}, volume={34}, url={https://www.notulaebotanicae.ro/index.php/nbha/article/view/298}, DOI={10.15835/nbha341298}, abstractNote={The study was carried out in an apple orchard and a laboratory of the Institute of Agriculture, Kyustendil, Bulgaria in seven consecutive years from 1998 to 2004. The apple cultivars Liberty, Cortland, Freedom, Gloster, Florina, Gala, Granny Smith, Smoothy, COOP - 10 and Golden Delicious were evaluated for susceptibility after artificial inoculation of annual growths (shoots) and fruits.<strong> </strong>Susceptibility of the cultivars Granny Smith, Smoothy and COOP 10 on rootstock M9 and MM106 were evaluated at natural infection in the orchards. The annual growths (shoots)<strong> </strong>and fruits<strong> </strong>of all evaluated cultivars were susceptible to <em>Botryosphaeria obtusa.</em> The shoots of the cultivars Liberty and COOP 10 were most susceptible to the black rot. It was established that the rootstock had a strong influence over the cultivars susceptibility. The cultivars COOP 10, Granny Smith and Smoothy were more susceptible when was grafted on rootstock M9 than on MM106.}, number={1}, journal={Notulae Botanicae Horti Agrobotanici Cluj-Napoca}, author={BOROVINOVA, Maria}, year={2006}, month={Aug.}, pages={100–105} }
