Effect of Biatorella canker on pollen viability and variation of shoot characters in Scots pine


Fungal canker caused by Biatorella difformis [Fr.] Rehm. has a deleterious effect on the productivity of Scots pine. Affected trees are characterized by decreased biometric parameters of shoots and needles and impaired pollen germination and tube growth. Their pollen has reduced contents of reserve nutrients and physiologically active substances.
