The manufacture of lily ovary slides showing the seven-to-eight- nucleate stage is unproductive and expensive. Most of the slides obtained from a ribbon show incomplete embryo sacs. Cutting an ovule longitudinally through the center and having all the nuclei in one section is a matter of chance. Commercial manufacturers have a sales outlet for slides having incomplete sacs and can therefore sell the few choice slides having complete sacs at reasonable cost. For routine teaching, with its attendant breakage of slides, it may be more satisfactory to purchase slides of the seven-to-eight-nucleate stage than to make them. Good fixation has been obtained with fair regularity with Allen-Bouin II and n-butyl alcohol Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Sass, John E.
