Optimizing Ficus Nota Water Priming for Accelerated Germination and Growth in Pechay (Brassica rapa subsp. chinensis)

This study addresses the imperative requirement to enhance seed germination rates and uniformity in seedling establishment for short-cultivation-period vegetable crops, with a focus on Pechay ( Brassica rapa subsp. chinensis). Employing seed invigoration techniques utilizing natural plant extracts, particularly Ficus nota water (FNW), we investigated the impacts of varied FNW concentrations (0%, 50%, 100%) and soaking durations (2, 4, 6 hours) on Pechay seeds. The combination of 50% FNW and a 4-hour soaking duration significantly accelerated germination rates by 60% compared to the control. FNW application also exerted a positive influence on seedling height, radical proliferation, and biomass accumulation. However, the persistent enhancement in height and late-stage leaf width expansion at a 50% concentration did not translate into corresponding improvements in productivity, suggesting potential trade-offs between morphological alterations and yield. This study offers preliminary evidence supporting FNW efficacy in expediting Pechay germination and invigorating nursery vigor, providing a foundation for optimized priming protocols and extended cultivation periods. Despite morphological stimulation, the absence of biomass enhancement prompts further exploration into the underlying growth dynamics, emphasizing the necessity for subsequent field trials to assess yield responses. Overall, this research contributes insights into the nuanced relationship between morphological modifications and productivity in FNW-primed Pechay cultivation.
