The Effect Of Pseudomonas Flourescens On The Germination And Plant Growth Of Papaya

Abstract

Pseudomonas flourescens were known as plant growth promoting rhizobacteria (PGPR). P. flourescens has a role to promote the plant growth and triggers induce systemic resistance (ISR) to against the pathogen. The objective of this research is to evaluate the influence of Pjlourescens on the germination and plant growth of papaya. The methods are the efficacy of P. flourescens to -germination of papaya seeds in laboratory and efficacy of P. flourescens on plant growth in green house. Papaya varieties were used in this research was hawaiii (HW), bangkok (BK), lokal (PR), and variety of papaya developed by Bogor Agricultural University (IPB). The result of this research, local papaya has a higher germination and plant height than other varieties. Most of application P. flourescens has a higher percentage of germination than control. There is increasing percentage of germination due to the using of P. flourescens. There is no difference plant height due to the different spraying time of P. flourescens.
