Abstract

Tropical ornamental Anthurium andraeanum requires substantial electrical heating for overwintering when cultivated in greenhouses in subtropical regions, making cold tolerance improvement a key factor for cost reduction. However, whether exogenous 6-Benzylaminopurine (6-BA) can enhance cold hardiness in Anthurium and its underlying mechanisms remain unclear. In this study, we conducted a controlled experiment to compare the physiological and biochemical responses of A. andraeanum ‘Alabama’ subjected to low-temperature stress following foliar application of 6-BA versus water. Our results show that, compared with water treatment, 6-BA application was associated with better preservation of subcellular structural integrity, higher proline accumulation, lower hydrogen peroxide content, decreased relative electrical conductivity, increased leaf fresh weight, dry weight, and area along with reduced water content, and lower stomatal density. These findings suggest that, under defined low-temperature conditions, 6-BA is associated with enhanced physiological performance in A. andraeanum, potentially through coordinated effects on subcellular stability, osmotic adjustment, reactive oxygen species accumulation, leaf morphology and water metabolism, and stomatal density. This work provides a theoretical basis and technical reference for cold-tolerant cultivation of Anthurium.
