Abstract
Morphometry, microfluorimetry and electron microscopy were used to inv estigate the size, ploidy level, and morphology of the nucleus of the individual cells forming the peltate and capitate glandular trichomes in Mentha x piperita L. Nuclear hypertrophy was observed in the secret ory cells of both kinds of trichomes. This could be explained by polyp loidization and by variations in chromatin structure which may be rela ted to increased transcriptional activity.
