| Abstract:
Excessive blind node production is observed more frequently in the southern as compared to the northern peach production areas. Although blind nodes may be mistaken as either bud drop or bud failure, they are distinct since the buds are only initiated but never fully develop. The development of buds was followed throughout the season (March to October) on eight peach genotypes (chilling requirement ranging from 150 to 850 units) at 2 or 3 sites for each. Correlation analysis indicated that blind nodes develop more readily under higher temperature conditions and during periods of less tree growth. | |
