Abstract

This experiment was conducted aiming to improve the germination and vigour traits of Asclepias procera by inoculation with PGPR. The study had 8 levels of inoculation including control, Pseudomonas, Azospirillum, Azotobacter, Azospirillum + Pseudomonas, Pseudomonas + Azotobacter, Azospirillum + Azotobacter, Azospirillum + Azotobacter and Pseudomonas in a completely randomized design with four replications. Results showed that inoculation of Calotrope seeds were significantly affected germination traits. The highest germination percentage (72 %) and germination rate (1.8 per day) was observed by inoculation with Pseudomonas putida strain 169 that respectively was 1.8 and 1.63 fold more than control treatment. The greatest root length (19.84 mm) and shortest mean germination time (7.97 days) was belonging to the Pseudomonas + Azotobacter inoculation, that respectively was 1.6 and 7 fold more and less than control. Greatest seed vigor index (17.8) was shown by Azotobacter + Azosprillum that were 1.82 fold more than control. This research revealed that the inoculation of rhizobacterial microorganisms is a new approach that can be effective to improve SEED GERMINATION in Calotrope shrubs.
