M. Kozlowska, PHENOLIC COMPOSITION OF RED RASPBERRY CANES IN RELATION TO DIDYMELLA-APPLANTA (NIESSL) SACC RESPONSE, Acta Physiologiae Plantarum, 16(3), 1994, pp. 211-215
Phenolic compounds from raspberry canes infected with D. applanata wer
e investigated by HPLC. Two major compounds identified as vanillyl alc
ohol and syringic acid increased in the surrounding zone of lesions an
d could be involved in the restriction of fungus. The most of the unid
entified peaks (appearing as glycosylated conjugates) decreased after
infection, but only inside the lesions. It is postulated that they may
be used up in lignin deposition.
