RESEARCHES ON THE VEGETATION PERIOD OF SOME MAIZE HYBRIDS ASESSED BY THE NUMBER OF LEAVE
Keywords:
maize, hybrids, number of leaves, precocityAbstract
For to define more accurately the precocity group of some maize hybrids depending
on vegetation conditions from maize growing area, different researches analyzed the
number of leaves as invariable factor dependent on hybrid. In this writing we offer
dates about number of leaves for ten maize hybrids cultivated in experimental field
from Varieties Testing Centre, Targoviste. Differences between hybrids were clearly
and for this reason we can classify these hybrids in two precocity groups (medium
early or late).
