The Effect of polyethylene glycol concentration on some varieties of kenaf (Hibiscus cannabinus L.) in enhancing the germination viability

Abstract

The purpose of this study was to see the interaction between the concentration of Polyethylene Glycol and various varieties of kenaf (Hibiscus cannabinus L.) On plant germination. This study used a completely randomized factorial design with 3 replications. The factors used for the study were varieties of kenaf (Karang Proso 6, Karang Proso 9 and Karang Proso 15) and the concentration of Polyethylene Glycol (0, 3, 5, and 7 ppm). Data were analyzed using analysis of variance (F test) using least significant difference (LSD) test of 5%. There was an interaction between the concentration of Polyethylene Glycol and kenaf varieties on germination power. Karang Proso 9 variety was consistent with several concentrations of Polyethylene Glycol which had higher germination compared to other varieties. Polyethylene Glycol concentration did not affect hypocotyl length, seed germination uniformity, dry weight of the varieties of Karang Proso 6, Karang Proso 9 and Karang Proso 15.
