Abstract
Abstract In 2021, an unprecedented heat event caused widespread damage to tree fruit crops across western North America. In a preliminary trial conducted that summer in an apple (var. “Fuji”) orchard in the Okanagan Valley, British Columbia, a calcium carbonate-based foliar protectant reduced severe sunburn by 9% and fruit asymmetry by 17% but had no other effects on fruit quality, water stress, or leaf gas exchange. With climate change, extreme heat events are projected to become more frequent and extreme. Foliar protectants show potential for preserving fruit quality, but further research is urgently required to optimize their use in Canada.
期刊介绍：
Published since 1957, the Canadian Journal of Plant Science is a bimonthly journal that contains new research on all aspects of plant science relevant to continental climate agriculture, including plant production and management (grain, forage, industrial, and alternative crops), horticulture (fruit, vegetable, ornamental, greenhouse, and alternative crops), and pest management (entomology, plant pathology, and weed science). Cross-disciplinary research in the application of technology, plant breeding, genetics, physiology, biotechnology, microbiology, soil management, economics, meteorology, post-harvest biology, and plant production systems is also published. Research that makes a significant contribution to the advancement of knowledge of crop, horticulture, and weed sciences (e.g., drought or stress resistance), but not directly applicable to the environmental regions of Canadian agriculture, may also be considered. The Journal also publishes reviews, letters to the editor, the abstracts of technical papers presented at the meetings of the sponsoring societies, and occasionally conference proceedings.
