Weitere Untersuchungen zur unterschiedlichen Anfälligkeit von Pinus nigra-Klonen gegenüber Scleroderris lagerbergii

Further studies on differing susceptibilities of Pinus nigra clones to Scleroderris lagerbergii. In a seed orchard 14 clones of Austrian black pine (Pinus nigra ssp. nigra) showed significant differences of susceptibility to Scleroderris lagerbergii. Significant clonal differences existed also in buffering capacity of homogenized bark tissue of one-year shoots. Less susceptible clones had a higher buffering capacity.
