摘要

Lilium spp., valued worldwide for their ornamental and medicinal properties, benefit from in vitro propagation techniques enhanced by silver nanoparticles (AgNPs). This study evaluated how different concentrations of Argovit™ AgNPs (0 to 100.0 mg•L⁻1) affect the growth and acclimatization of Lilium ‘Concador select’ micro-bulbs. Plants were cultured in modified Murashige and Skoog medium and later acclimatized in peat-vermiculite trays across two research sites in Saltillo, Mexico. Key morphological traits were measured after transplant. Statistical modeling revealed that bulb diameter responded most consistently to AgNP treatment, making it a reliable indicator of effectiveness. Cluster analysis grouped nanoparticle doses into three categories, showing that moderate concentrations promoted uniform growth, while very low or high doses led to variable outcomes. These findings supported the targeted use of AgNPs to improve micropropagation efficiency and informed breeding and conservation strategies for Lilium.
