DATE PALM MICROPROPAGATION<br />

Figure 2. Date palm shoot tip region dissection stepwise procedures used to excise leaf<br />

primordia <strong>and</strong> tip explants <strong>for</strong> culture initiation. A) Make a longitudinal cut in the sheath<br />

surrounding the immature leaf petioles. B) Remove <strong>and</strong> discard the leaf petioles surrounding<br />

the tip in a whorl fashion until 4 or 5 are remaining. C) Remove the remaining petioles <strong>and</strong><br />

keep <strong>for</strong> explanting. D) Exposing the leaf primordia <strong>and</strong> leaf tip meristematic region. E)<br />

Note the bright white region where an axillary bud has <strong>for</strong>med at the base <strong>of</strong> the immature<br />

interior leaf petioles. F) Selection <strong>of</strong> tissue with meristematic regions including immature<br />

petiole bases <strong>and</strong> shoot tip shown still surrounded by leaf primordial. G) Dissection <strong>of</strong> the<br />

immature axillary bud regions from the petiole. H) Explants isolated from shoot tip region<br />

ready <strong>for</strong> inoculation. I) Explants on culture initiation medium containing activated charcoal.<br />
