Pertumbuhan, Produksi Fenolik dan Flavonoid Adenostemma platyphyllum pada Konsentrasi Larutan Hara Hidroponik Sistem Sumbu Berbeda

Abstract

Adenostemma platyphyllum, known as legetan warak, is a weed with various benefits but has not been widely cultivated. This work aims to obtain the optimum concentration of a nutrient solution (AB mix) to produce optimum growth, phenolic and flavonoid levels in the cultivation of legetan warak using a hydroponic wick system. A one-factor randomized block design was employed in the form of different concentrations of the AB mix nutrient solution. The concentration of 900 ppm gave best growth, although it was not significantly different from concentrations of 700, 1100, and 1300 ppm. The highest total phenolic and flavonoid levels were in plants without additional nutrient solutions, but the highest phenolic and flavonoid productivity was found in plants with a nutrient solution concentration of 900 ppm. Therefore, the optimum concentration of nutrient solution to produce optimum plant growth, phenolic and flavonoid levels in legetan warak cultivation by hydroponic wick system was the concentration of 900 ppm.
