Abstract

Abstract Suitable rootstock enhances apple tree resilience. In 2021, we studied “Buckeye Gala” apple (Malus domestica var. Buckeye Gala") on nine rootstocks with contrasting vigor in NS and BC, Canada. Rootstock effects on vigor, yield, and midday stem water potential were significant in BC. After sustained heat events, the large-dwarfing rootstocks Geneva 935, Geneva 4814, and Geneva 969 had lower ratio of sunburn fruits, resulting in higher projected damage-free yield. We discussed how higher stem water potential and larger canopy volume supported by vigorous rootstocks contributed to alleviate heat stress and improve apple resilience to global warming.

果树气候适应性工具I：大型矮化砧木可以减轻“七叶树Gala”苹果的晒伤

适宜的砧木可提高苹果树的抗逆性。2021年，我们在加拿大NS和BC的9根砧木上研究了“Buckeye Gala”苹果(Malus domestica var. Buckeye Gala)。砧木对冬小麦活力、产量和正午茎秆水势的影响显著。在持续高温条件下，大矮化砧木日内瓦935、日内瓦4814和日内瓦969的晒伤果实率较低，预计无害化产量较高。本文讨论了在粗壮砧木的支持下，较高的茎水势和较大的冠层体积对缓解苹果热胁迫和提高苹果对全球变暖的适应能力的作用。

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.
