ESTIMATE OF CHILLING REQUIREMENTS OF APRICOT SELECTIONS

C.H. Bailey, W. Cowgill, L.F. Hough
Histological studies were made of apricot selections and several late blooming apricot cultivars to determine time of meiosis and time of fully formed pollen grains. The time of first bloom was also noted. These data were used to estimate the number of weighted chilling hours needed to satisfy rest and the number of growing degree hours (after meiosis) required for first bloom.
