Effect of coconut water and banana hump extract on the growth of binahong (Anredera cordifolia (Ten.) Steenis) accessions from lowland

Abstract

The application of natural plant growth regulators (PGR) influences the growth of binahong (Anredera cordifolia (Ten.) Steenis). The objective of the current research is to evaluate the growth component of lowland binahong accessions due to the application of natural PGR of coconut water and banana hump extract. The research used factorial randomized block design with 2 factors and 3 replications. The first factor was different accessions of binahong from lowlands (Marelan; Ampera Tmur; Helvetia) in the city of Medan, North Sumatera, Indonesia. The second factor was natural PGR, in which we conducted experiments without the application of PGR; 40% coconut water application, banana hump extract 40%; coconut water 40% + banana hump extract 40%. The results showed that the accessions from Ampera Timur had root dry weight that were higher than the other accessions. The treatment of 40% coconut water + banana hump extract 40% increased plant length, and root dry-weight. Interaction of Ampera Timur binahong accession and 40% coconut water + banana hump extract 40% increased shoot dry-weight and root dry-weight.
