English
This review synthesizes physiological, biochemical, and modeling knowledge on carbon allocation in perennial fruit crops, focusing on source-sink interactions. It covers apple, grape, citrus, peach, and mango, examining how sink demand regulates source activity and how drought, heat, elevated CO2, and nutrient stress affect carbon dynamics. The authors propose an integrated framework for optimizing sink activity and reserve dynamics to sustain yield and quality under climate change, highlighting the need for climate-smart orchard management.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の果樹農業は気候変動の影響を受けやすく、高温や干ばつによる品質低下が懸念される。本レビューは、炭素配分の理解を通じた気候適応策の基礎を提供し、日本の果樹産地における栽培管理や品種開発に示唆を与える。ただし、直接的なGX政策や開示には関連しない。
In the global GX context
Globally, fruit production faces increasing climate risks, and understanding carbon allocation is key to developing resilient cultivars and management practices. This review contributes to climate adaptation literature by integrating physiological and modeling insights, which can inform sustainable orchard systems under changing climates. It does not directly address emissions reduction or disclosure frameworks.
👥 読者別の含意

🏢実務担当者:Offers insights for orchard management to optimize yield and quality under climate stress, but not directly actionable for disclosure teams.
🏛政策担当者:May inform agricultural adaptation policies, but lacks direct policy recommendations.
📄 Abstract（原文）
Carbon allocation and source-sink interactions are fundamental determinants of yield, fruit quality, and climate resilience in perennial fruit crops. Unlike annual species, fruit crops must continuously distribute assimilates among reproductive, vegetative, and storage sinks, balancing current production with future growth. Although photosynthetic carbon supply has traditionally been regarded as the primary driver of productivity, increasing evidence shows that sink demand actively regulates source activity through metabolic and signalling feedback, making crop performance dependent on the coordinated interaction of source capacity, sink strength, phloem transport, and non-structural carbohydrate reserves. This review synthesizes current physiological, biochemical, and modelling knowledge to develop an integrated framework for understanding carbon allocation in major fruit crops, including apple, grapevine, citrus, peach, and mango. It examines the roles of carbohydrate reserves, sink activity, and phloem transport in regulating fruit growth, quality, and seasonal carry-over effects, while highlighting the impacts of drought, heat stress, elevated atmospheric CO₂, and nutrient limitations on source-sink coordination. Emerging approaches for analysing carbon dynamics and key research priorities are also discussed. Optimizing sink activity and reserve dynamics, together with climate-smart orchard management, is essential for sustaining fruit productivity, quality, and resilience under changing climatic conditions.
