The effect of Rootone-F and coconut water on Piper sp. cutting growth

Abstract

Betel is propagated by stem cutting. The success of cutting is determinate by many
new roots and leaves. Synthetic or natural plant growth regulators can do induction root. This
research aims to observe plant growth regulators to optimum growth of green and red betel. A
completely randomized design with two factors was design treatment. The first factor was betel
type (green betel and red betel), and the second factor was plant growth regulator, namely
Rootone-F (5%, 10%, 15%, 20%, and 25%), coconut water (15%. 25%, 50 %, 75%, 100%),
and control (water). Repeated the treatment was three times. The observed characters were life
percentage, root percentage, root length, and plant height. Data obtained were analyzed with
SAS 9.1 software. The results showed that green and red betel could be propagated more
effectively with water than the provision of growth regulators Rootone F and coconut water.
Increasing the concentration of Rootone F and coconut water significantly reduces root length
and shoot length.
