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.

果树气候适应性工具II：在前所未有的高温事件中，基于碳酸钙的叶面喷雾显示出保护果实质量的潜力

摘要2021年，一场前所未有的高温事件对北美西部的果树作物造成了广泛破坏。那年夏天，在不列颠哥伦比亚省奥卡纳根山谷的一个苹果园（变种为“富士”）进行的一项初步试验中，一种碳酸钙基叶面保护剂可以减少9%的严重晒伤和17%的果实不对称，但对果实质量、水分胁迫或叶片气体交换没有其他影响。随着气候变化，预计极端高温事件将变得更加频繁和极端。叶面保护剂显示出保持水果品质的潜力，但迫切需要进一步的研究来优化其在加拿大的使用。

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.
