Protecting Stone Fruit Flower Buds from Winter Freeze Damage
Flower buds of peach, apricot, and sweet cherry are killed by low temperatures during winter and spring. Frost protection measures used commonly in the spring are applied to freeze protection during the winter in the Yakima Valley of Washington. Critical temperatures change rapidly during winter. To succeed, winter freeze protection requires adequate inversions, equipment that operates at tempe...
متن کاملFreezing characteristics and texture variation after freezing and thawing of four fruit types
One major problem with frozen fruits is a loss of texture. Therefore this study investigated the effects of the freezing process on the freezing profiles, texture, and drip loss of apple, mango, cantaloupe, and pineapple fruit samples. All frozenthawed fruits varied in these three properties because of diversity in the fresh fruits. Mango had the highest total soluble solids content and the low...
متن کاملFreezing of water in dormant vegetative apple buds in relation to cryopreservation.
Various empirical prefreezing protocols have been used to facilitate cryopreservation of dormant buds from woody plants. The objective of this research was to determine the quantity of water remaining in liquid phase, under different prefreezing conditions using pulsed nuclear magnetic resonance spectroscopy of dormant apple (Malus domestica Mill.) buds from three cultivars. During prefreezing,...
متن کاملIce nucleation activity in various tissues of Rhododendron flower buds: their relevance to extraorgan freezing
Wintering flower buds of cold hardy Rhododendron japonicum cooled slowly to subfreezing temperatures are known to undergo extraorgan freezing, whose mechanisms remain obscure. We revisited this material to demonstrate why bud scales freeze first in spite of their lower water content, why florets remain deeply supercooled and how seasonal adaptive responses occur in regard to extraorgan freezing...
متن کاملan investigation on freezing tolerance of peach and nectarine reproductive buds in controlled conditions
damage caused by freezing can be the result of differences in cellular processes, including changes in membrane properties, interactions between macromolecular and enzymatic reactions. in this experiment, total soluble solids (tss) and relative water content of the reproductive buds of cultivars “j. h. hale”, “elberta,” “redhaven, ” “sorkh sefid mashhad” and “amsden” peaches, along with nectari...
