Abstract
The Feulgen-DNA content of 3558 nuclei from 21 different tissues and organs ofScilla decidua (Liliaceae) was measured by a scanning cytophotometer interfaced to a computer. The basic nuclear DNA content (2 C value) was 13.62 pg, and 71 per cent of the nuclei were polyploid. The highest DNA values were found in the antipodal cells of the ovule, and the elaiosomes of the seeds (512 C). In addition to polyploidy, the 2 C values exhibited tissue-specific variation which was statistically significant (0.05% level of probability), It is suggested that differential DNA replication and endopolyploidization may be basic factors in the complex mechanism of cell and tissue differentiation.
