The agricultural production value of Japan is 9.0015 trillion yen, of which the horticultural sector accounts for approx. 40%, including vegetables (2.2298 trillion yen), fruits (923.2 billion yen), and flowers (349.3 billion yen) (FY 2022 statistics). The Japanese horticultural industry faces issues such as an aging and declining labor force, drastic climate changes due to the global warming, and the relative decline of domestic industries due to market globalization. In this lecture, I will introduce the current state of the Japanese horticultural industry and the efforts to address these issues, including the development of labor-saving production technologies, enhancing the resilience of the industry to adapt to the environmental changes, and strengthening international industrial competitiveness.

Horticultural crops is big category of plant industry in China, including fruits, vegetables, ornamental plants and tea; These crops used about one quarter of the farmland, but generated more than half of the farm-gate value for the whole plant industry in China. Vegetable and fruit productions account for about 50% and 30% of the world respectively in recent years. The horticultural industry has benefited not only the consumers with diversified and year around evenly supply of fresh fruit & vegetable products, but also has been increasing the income of growers and distributors, as has greatly contributed to the poverty alleviation and rural development in the countryside. With the increasing labor cost and land value, the horticultural industry has been moving from the eastern-area where is better developed, to the middle- and western-area, with one point of percentage each year during the last decade. During the last 10 years, the horticultural industry has kept a stable developing step with minor increment of acreage, but improved the industry with better quality cultivars and higher production efficiency. More and more horticultural crops will be grown under the protected space including plastic- or screen-houses for alternative season supply or for protecting the crops from the insect or diseases. The smart and AI technologies are being merged into the industry from breeding to the post-harvest. These improvement have relied on the germplasm enhancement, more new varieties release, more efficient culture practices and more professional personnel. Government-supported national germplasm banks and repositories ex situhave preserved 38 thousands and 23 thousands accessions for vegetables and fruits respectively. Since the new century, the national and local government has increased the investments to horticulture research, including stable financial support to more 50 horticultural crops under the CARS (China Agriculture Research System) program. Mult-omics have been widely used in most horticultural crop researches, as helped understand the molecular base of important traits and identify the key genes conferring these traits such as citrus oil gland initiation, rose special fragrance, and cucumber bitterness etc. High education has greatly supported the industry development; now there are more than 120 universities or colleges offer undergraduate program for horticulture, about 50 institutions for master-degree and 30 institutions for PhD degree.

Laval University

In his keynote lecture at IHC-2026, Prof. Desjardins will explore the emerging concept of “Symbiotic Humans”—how the regular consumption of horticultural commodities shapes our microbiota and, in turn, our health. He will discuss the pivotal role of fruits and vegetables as modulators of human–microbial symbiosis and as key actors in the broader framework of One Health, linking soil, plant, and human well-being within a sustainable ecosystem.

Following pollination, many molecules, including key signaling molecules involved in the interactions between male and female cells, function to achieve pollen tube guidance and double fertilization, processes essential for seed and fruit development through sexual reproduction. In this talk, I will introduce key signaling molecules identified through live-cell imaging approaches in both model and non-model plant species. I will also discuss the applications of these molecules, the technologies used, and the molecular insights gained.

Breeding in many different crops has been done for a long time based on phenotypic improvement of  offspring performance. That is now changing dramatically due to the availability of genomics in many crops including ornamentals which makes breeding more efficient and effective. It now has also become possible to breed for specific niche markets in crops which can even be polyploid, vegetatively propagated and /or so called orphan crops. While breeding for resistance to biotic stress -and increasingly also for tolerance or resistance to abiotic stress- is still the most important target in breeding also other breeding goals are receiving more attention. The challenges (climate change)  and demands (feeding nine billion people) are plentiful making a faster and more precise breeding of  crops necessary. Furthermore given the current developments in the world it has become increasingly evident that every country or region should be able to produce a certain amount of food for their citizens themselves (25-40% own production). At the same time programs like Europe’s Green Deal require different and alternative production systems and thus also crops. In some areas this means that alternative farming systems will have to be set up and exploited like food forests, strip cropping, intercropping, cropping of novel crops and controlled environmental agriculture (or vertical farming). This all together poses challenges and possibilities as new tools and techniques can increase the speed, efficiency and efficacy by which varieties for these new farming systems can be generated. A shift to more dedicated breeding other then only yield is thus required. For example automation and mechanization because human labor has become too expensive or simply is not available will require a different architecture of crops to be able to harvest the products in a good way. Also transport of foods around the world is increasingly shifting to sea transport which will increase the time between harvest and sale to consumers meaning that varieties with increased postharvest quality have to be bred. In this presentation I will provide some examples of how we aim to address these different challenges.

Anthropogenic emissions of greenhouse gases since the pre-industrial era have increased markedly, leading to an unprecedented rise in global surface temperatures and more frequent climate and weather extremes. While immediate action is needed to slow temperature rise, urgent adaptation to the changing climate is also essential. The agricultural sector, highly dependent on climate resources, is among the most affected. This presentation will highlight recent assessments of climate-related risks and adaptation strategies in the food sector, emphasizing the importance of scientific understanding and multi-dimensional evaluation of adaptation measures. I will discuss how increasing risk levels can be addressed through a range of effective adaptation strategies, highlighting how these approaches can help prevent maladaptation.
