摘要

Guava (Psidium guajava L.), a tropical fruit crop with significant commercial value, is well-known for its strong nutritional and health benefits. However, its sustainable production is now seriously threatened by climate change. Increased greenhouse gas levels, unpredictable rainfall, long droughts, and rising temperatures all impact guava’s growth phases, yield, and fruit quality. Changes in rainfall and temperature significantly affect the growing processes such as flowering, fruit set, and maturation. This can result in poor fruit set, irregular blooming, and altered harvest times. As climate conditions shift, heat stress, soil moisture shortages, and a rise in pests and diseases are becoming increasingly linked to lower yields. Furthermore, marketability and customer acceptance are compromised due to the negative effects on fruit quality attributes such as size, flavor, pulp-to-seed ratio, sugar content, vitamin C concentration, and antioxidant potential. Research shows a strong positive connection between honey bee density and guava fruit set and pollination rates. Using honey bees can boost fruit set by 20–40%. Better pollen transfer is associated with a higher number of bee visits per flower, which leads to improved fruit quality in terms of size, weight, and seed development, along with higher fertilization success and fruit set percentage. However, climate change negatively impacts pollinator activity and numbers through increased temperatures, altered flowering patterns, and habitat stress, resulting in lower guava yields. Although adaptive strategies such as crop diversification, precision irrigation, mulching, canopy management, and advanced horticultural practices provide some resilience, long-term solutions require detailed climate modeling and genetic strategies to develop stress-tolerant varieties. This review emphasizes the major challenges that climate change poses to guava’s growth phases, yield, and quality. It also stresses the need for integrated adaptive methods that combine precision technologies, biotechnological innovations, and traditional practices.
