Abstract
Fusarium oxysporum, Phomopsis sp., Fusan'um monififorme and Fusarium
soiani were isolated from leaves, basal of leaves, crown area and roots of date
palm tissue culture (Phoenix dactylifera L.) and found to be pathogenic to it. The
plants showing wilt of leaves, necrosis at the basal of leaves, canker of crown area
and heart rot symptoms in greenhouse (2 years after acclimatization). Fixed section
through infected tissues showed that the fungi caused necrotic area and gum block in
vascular bundle and paranchymatous (F. oxysporum). Tylosis like bodies in
metaxylem vessel (Phomopsis sp.) while the mycelium of F. moniiifonne and F.
soiani were found inter- and intracellular paranchymatous tissues. All tested fungi
destroyed some of vascular bundles and paranchymatic cells which were filled with
brown materials. Free and conjugated phenol contents were higher in infected tissues
than determined in health ones, while the sugar contents were reduced in infected
fissues.
