摘要:
Seeds were sown on mineral agar and grown under axenic constant conditions. Floral transition and flower primordia were observed at approximately 172 and 220 hr, respectively. The vegetative apex was flat in outline for 160 hr, after which time it was slightly dome shaped; cytohistological zonation was not readily apparent. The inflorescence apex (172 hr) was markedly convex and possessed 3–5 and 4–6 cell layers in the most axial and lateral portions of the apex, respectively. The nucleoli of cells of the T2layer were larger than cells of the T1and outer corpus during vegetative development; in contrast, they were equal in size at reproductive stages.
