| Summary: | Cross-sections of leaf blades and petioles of different strawberry genotypes exhibiting different
levels of resistance to Chaetosiphon fragaefolii were studied using the paraffin method, and staining
with safranin, crystal violet and light green. Besides thicker cell walls of the cortex collenchyma in
the more resistant genotypes, and a proportionally wider collenchyma than parenchyma in the
cortex, their midribs are also encircled by a ring of more intensely stained lignified cells forming a
physical ring. This stain reaction of cells to safranin and crystal violet occurs also in lateral vascular
bundles, as well as in leaf palisade tissue. The tissue cross-sections of the sensitive genotypes
revealed a predominance of green on the cellulose cell walls and protoplasts due to the reaction
to light green SF, while stain reactions to safranin and crystal violet were not evidenced. |
