Role of Bioactive Compounds and Artificial Intelligence Tools in Advancing Modern Horticulture

1. Introduction

Horticulture plays a vital role in global food security, nutrition, human health, and economic development, particularly through the production of fruits, vegetables, ornamental plants, and medicinal crops. As consumer demand for high-quality, safe, and nutritionally rich horticultural produce continues to rise, the sector faces increasing challenges related to climate change, resource scarcity, environmental degradation, and labor shortages [1]. Conventional horticultural practices that rely heavily on synthetic fertilizers and pesticides are becoming less sustainable due to their adverse impacts on ecosystems, soil health, biodiversity, and human well-being. Consequently, there is a growing need for innovative, environmentally responsible approaches that enhance productivity while reducing ecological footprints, bioactive compounds have emerged as promising tools for advancing sustainable horticulture. These compounds, which include plant growth regulators, biostimulants, secondary metabolites, and elicitors, exert significant influence on plant physiological and biochemical processes even at low concentrations [2]. Bioactive compounds enhance nutrient use efficiency, stimulate growth and development, improve yield and quality, and strengthen plant tolerance to abiotic and biotic stresses. Unlike traditional agrochemicals, many bioactive compounds act by modulating endogenous signaling pathways and metabolic functions, making them particularly valuable for improving crop resilience under changing environmental conditions.

Parallel to advancements in plant-based inputs, digital technologies—particularly artificial intelligence (AI)—are transforming modern agricultural systems. Artificial intelligence encompasses a range of computational techniques, including machine learning, deep learning, computer vision, and data-driven decision-making systems, that enable the analysis of complex and large-scale datasets. In horticulture, AI tools facilitate precision farming by improving crop monitoring, disease detection, yield prediction, irrigation management, and post-harvest handling. These technologies allow growers to make timely, accurate, and site-specific decisions, reducing waste and optimizing the use of inputs.The integration of bioactive compounds with artificial intelligence tools represents a powerful and emerging paradigm in modern horticulture. AI-driven systems can identify crop stress at early stages, predict plant responses, and guide the precise application of bioactive compounds tailored to specific crop needs and environmental conditions [3]. This synergy enhances the effectiveness of bioactive substances while minimizing overuse, thereby supporting sustainability goals. Moreover, AI-assisted data analytics accelerate the development and optimization of bioactive formulations by uncovering patterns in plant responses across diverse environments. A holistic understanding of how these two domains intersect is essential for advancing climate-resilient, resource-efficient, and high-value horticultural systems [4]. Therefore, this review aims to critically examine the role of bioactive compounds in horticulture, explore important artificial intelligence tools and their applications, and highlight the synergistic integration of these approaches in advancing modern horticultural practices. The review also discusses future prospects, challenges, and research directions for the sustainable transformation of horticulture through bioactive compounds and AI-driven technologies.

2. Bioactive Compounds in Modern Horticulture

Bioactive compounds are increasingly recognized as essential components of sustainable horticultural production systems due to their ability to regulate plant physiological and biochemical processes at low concentrations. These compounds influence growth, development, and stress responses by interacting with plant hormonal pathways, metabolic networks, and gene expression mechanisms. Unlike conventional fertilizers that primarily supply nutrients, bioactive compounds function as regulators and enhancers of plant performance, enabling crops to achieve higher productivity and quality with reduced reliance on synthetic agrochemicals. Their use aligns with global efforts to promote environmentally responsible and climate-resilient agricultural practices.Among bioactive compounds, plant growth regulators play a central role in shaping horticultural crop development [5]. Auxins, cytokinins, gibberellins, abscisic acid, ethylene, and brassinosteroids collectively regulate critical processes such as cell division, elongation, flowering, fruit set, ripening, and senescence. The strategic application of these regulators has been widely adopted to improve crop uniformity, increase yield, and enhance marketable quality in fruits, vegetables, and ornamental plants. By fine-tuning endogenous hormone balance, plant growth regulators help optimize physiological responses throughout different growth stages.

Secondary metabolites represent another important class of bioactive compounds with significant implications for horticulture. These naturally occurring compounds, including phenolics, flavonoids, alkaloids, and terpenoids, contribute to plant defense mechanisms, stress tolerance, and sensory attributes such as color, flavor, and aroma. In horticultural crops, secondary metabolites enhance resistance to pests and diseases while simultaneously improving nutritional and functional properties that are highly valued by consumers [6]. Their antioxidant activity also plays a crucial role in protecting plant tissues from oxidative damage, particularly under stress conditions.

Plant biostimulants have gained considerable attention as sustainable inputs that improve plant performance by stimulating natural physiological processes. Derived from sources such as seaweed extracts, humic substances, amino acids, and beneficial microorganisms, biostimulants enhance nutrient uptake efficiency, root development, and tolerance to abiotic stresses such as drought, salinity, and temperature extremes. Their application not only improves crop vigor and yield but also contributes to improved soil health and microbial activity, making them particularly suitable for integrated and organic horticultural systems.Elicitors further strengthen plant defense by activating innate immune responses without directly targeting pathogens. Compounds such as salicylic acid, jasmonic acid, chitosan, and microbial-derived molecules trigger systemic resistance, enabling plants to respond more effectively to biotic stress [7]. The use of elicitors reduces dependence on chemical pesticides and supports environmentally friendly pest and disease management strategies. Collectively, bioactive compounds play a multifaceted role in enhancing horticultural productivity, quality, and resilience while supporting sustainable production systems.

3. Artificial Intelligence Tools in Horticultural Systems

Artificial intelligence has emerged as a transformative force in modern horticulture by enabling data-driven decision-making and precision management of crops. AI technologies are capable of processing large and complex datasets generated from sensors, imaging platforms, weather stations, and farm management systems. Through pattern recognition, predictive modeling, and automated decision support, AI tools help optimize horticultural practices while reducing resource use and production risks [8]. These technologies are particularly valuable in high-value horticultural systems where precision and efficiency are critical.Machine learning algorithms have been widely applied to model crop growth, predict yields, and assess environmental impacts on plant performance. The learning from historical and real-time data, machine learning systems can forecast disease outbreaks, nutrient deficiencies, and stress conditions before visible symptoms appear. Deep learning models, especially convolutional neural networks, have demonstrated exceptional accuracy in image-based applications such as plant disease detection, pest identification, fruit counting, and maturity assessment. These capabilities enable rapid and non-destructive monitoring of crops across large production areas [9].Computer vision technologies further enhance horticultural management by enabling automated analysis of visual plant traits. Cameras mounted on drones, robots, or stationary platforms capture high-resolution images that are analyzed to evaluate plant health, canopy structure, fruit quality, and yield potential. In post-harvest operations, computer vision systems are widely used for sorting and grading fruits and vegetables based on size, color, shape, and surface defects, ensuring consistent quality and reducing post-harvest losses.

AI-driven decision support systems integrate agronomic, climatic, and operational data to provide real-time recommendations for irrigation scheduling, nutrient management, and pest control. These systems assist growers in applying inputs at optimal times and locations, improving resource use efficiency and minimizing environmental impacts. In protected cultivation systems such as greenhouses and vertical farms, AI algorithms dynamically regulate temperature, humidity, light, and carbon dioxide levels to create optimal growing conditions, resulting in higher yields and improved crop quality.Robotics and automation represent another significant application of artificial intelligence in horticulture. AI-powered robots are increasingly used for planting, pruning, harvesting, and targeted spraying, particularly in horticultural operations. These systems reduce labor dependency, improve operational precision, and enable continuous monitoring and intervention. As AI technologies continue to evolve, their integration into horticultural systems is expected to play a central role in enhancing productivity, sustainability, and resilience in the face of global agricultural challenges.

This precision approach enhances the efficacy of bioactive inputs while minimizing waste, environmental contamination, and production costs. By aligning plant physiological needs with data-driven decision-making, the integration of these technologies supports more efficient and sustainable horticultural systems.

AI-based monitoring tools facilitate early detection of abiotic and biotic stresses through the analysis of plant images, spectral data, and sensor outputs. Once stress symptoms are identified, bioactive compounds such as biostimulants and elicitors can be applied strategically to mitigate adverse effects and strengthen plant defense mechanisms. This proactive management approach improves crop resilience, reduces reliance on chemical pesticides, and enhances overall plant health. The combination of early stress diagnosis and targeted intervention is particularly valuable in high-value horticultural crops, where yield losses can have significant economic consequences. Artificial intelligence algorithms dynamically regulate microclimatic factors such as temperature, humidity, light intensity, and carbon dioxide levels while coordinating the application of growth regulators and biostimulants. This synchronized management creates optimal growth conditions, leading to increased productivity, uniformity, and product quality. AI-driven systems enable continuous optimization by learning from plant responses over time, further enhancing system efficiency [11].Artificial intelligence also plays a crucial role in accelerating the development and optimization of bioactive compound formulations. Ananalyzing large datasets generated from field trials and laboratory experiments, AI tools can identify patterns in plant responses and predict the effectiveness of specific compounds or combinations. This data-driven approach reduces the time and cost associated with product development and supports the creation of customized bioactive solutions tailored to specific crops, environments, and production systems.
