In Vitro Propagation and Secondary Metabolite Production of Medicinal Plant of Euchresta horsfieldii (Lesch) Benn.

Abstract

Euchresta horsfieldii (Lesch) Benn. is a highly demanded medicinal plant with many benefits. In vitro propagation through callus induction is an effective method for rapid multiplication in a short time. This research aimed to evaluate the effective concentration of Benzyl Amino Purine and 2,4-Dichlorophenoxiacetic acid on callus induction and organogenesis for in vitro propagation and secondary metabolite production of E. horsfieldii. The design used in this research was a Complete Randomized Design in 2 factors: Benzyl Amino Purine and 2,4-Dichlorophenoxiacetic acid with 5 levels for each concentration. Parameters observed are the percentage of inducted calluses, callus appearance time, the weight of fresh calluses, the weight of dry calluses, the texture of callus, the color of callus, percentage of the formed shoot, shoot appearance time, the height of shoots, the number of leaves, flavonoid compounds of callus, and bioactive compounds. The result showed that the single treatment of Benzyl Amino Purine and 2,4-Dichlorophenoxiacetic was significantly affecting the shoots forming. The concentration of 2,4-Dichlorophenoxiacetic 0 ppm gave the highest average plantlet height by 2.67 cm, increasing the number of shoots by 2.00, and the number of leaves by 5.60. E. horsfieldii cultured in vitro without additional growth regulators had a higher flavonoid content.
