An investigation was conducted to establinh the nature and incidence of amorphous and fibrous occlusions in the xylen of diseased and healthy appearing citrus trees in the greenhouse. Trees that were examined included 8-yr old Valencia orange plants on rough lemon rootstocks as well as 20-month-old Valencia and rough lemon seedlings exhibitings either Fusarium or Phytophthora root rot. Cross sections of roots, stems and branches were cut with a cryostat and prepared for scanning electrom microscopy and light microscopy. Amorphous occlusions were similar to those associated with citrus blight. In some instances more than ten amorphous occlusions were observed per 200 xylen vessels, These results may have important implications pertaining to the etiology of citrus blight. |
