Climate Change Affects Winter Chill for Temperate Fruit and Nut Trees
BACKGROUND Temperate fruit and nut trees require adequate winter chill to produce economically viable yields. Global warming has the potential to reduce available winter chill and greatly impact crop yields. METHODOLOGY/PRINCIPAL FINDINGS We estimated winter chill for two past (1975 and 2000) and 18 future scenarios (mid and end 21st century; 3 Global Climate Models [GCMs]; 3 greenhouse gas e...
متن کاملA global analysis of the comparability of winter chill models for fruit and nut trees
Many fruit and nut trees must fulfill a chilling requirement to break their winter dormancy and resume normal growth in spring. Several models exist for quantifying winter chill, and growers and researchers often tacitly assume that the choice of model is not important and estimates of species chilling requirements are valid across growing regions. To test this assumption, Safe Winter Chill (th...
متن کاملClimatic Changes Lead to Declining Winter Chill for Fruit and Nut Trees in California during 1950–2099
BACKGROUND Winter chill is one of the defining characteristics of a location's suitability for the production of many tree crops. We mapped and investigated observed historic and projected future changes in winter chill in California, quantified with two different chilling models (Chilling Hours, Dynamic Model). METHODOLOGY/PRINCIPAL FINDINGS Based on hourly and daily temperature records, win...
متن کاملBiotechnology of temperate fruit trees and grapevines.
Challenges concerning fruit trees and grapevines as long lived woody perennial crops require adapted biotechnological approaches, if solutions are to be found within a reasonable time frame. These challenges are represented by the need for correct identification of genetic resources, with the foreseen use either in conservation or in breeding programmes. Molecular markers provide most accurate ...
متن کاملAccumulated winter chill is decreasing in the fruit growing regions of California
We examined trends in accumulated winter chill across the fruit growing region of central California and its internal coastal valleys. We tested the hypothesis that global warming is in motion in California and is causing accumulated winter chill to decrease across the fruit and nut growing regions of California. The detection of potential trends in accumulated winter chill (between 0 and 7.2°C...
