Effect of a Newly-Developed Nutrient Solution and Electrical Conductivity on Growth and Bioactive Compounds in Perilla frutescens var. crispa

We evaluated the effect of a newly-developed nutrient solution red perilla (NSP) with various electrical conductivity (EC) levels on plant growth, mineral content, and bioactive compounds. Four-week-old seedlings were grown in greenhouse as control (CT) (EC 1–3 dS m−1) or NSP 1–6 m−1). 1 m−1 induced better growth characteristics, whereas higher EC inhibited growth. Most macro-elements contents significantly decreased under 6 m−1, micro-elements fluctuated according to levels. Total phenolic concentration was lower than that CT, total content highest m−1. anthocyanin antioxidant concentrations increased at Rosmarinic caffeic acids levels, there no significant differences these compound among No difference perillaldehyde observed, Overall, results suggest is suitable for cultivating factories.
