EFFECT OF WINTER OIL AND DORMEX SPRAYS ON FRUIT QUALITY AND STORAGE ABILITY OF LECONTE PEAR FRUITS
Pomology Dept., Fac. of Agric., Mansoura Univ., Egypt.
Abstract
This investigation was carried out during 2005 and 2006 seasons to study the effect of spraying Leconte pear trees with winter oil at 2 % and Dormex at 1, 2 % each alone or in combination as Dormancy breaking agents to study their effect on fruit quality at harvest time and storage ability through marketing for 6 days under room temperature. The data revealed that dormex at 1 or 2 % each alone or with winter oil significantly increased fruit weight, firmness and SSC/acid ratio at harvest than spraying with winter oil or the control. Furthermore, winter oil alone or with dormex significantly reduced the percent of total loss in fruit weight than those sprayed with dormex alone or the control.
Fruit firmness was reduced but total caroteniods and SSC/acid ratio were increased through marketing after 6 days from harvest. In this respect, sprayed Le-Conte pear with both winter oil and Dormex at 2 % gave a more pronounced effect on fruit quality at harvest time and through marketing.
