Different aging pattern in normal and red seeds of haynaldia villosa a cyto photometric analysis in resting root meristems






Giornale Botanico Italiano 114(1-2): 29-36

Different aging pattern in normal and red seeds of haynaldia villosa a cyto photometric analysis in resting root meristems

Cytophotometric determinations of DNA and histones content per nucleus were carried out in the 2C root meristematic nuclei from yellow and red seeds of H. villosa of different ages; the histones/DNA ratio increases during the storage period in the yellow seeds while it is almost constant in the red ones. The possible significance of these observations in relation to seed aging is discussed.
