Bacillus subtilis QM3, a Plant Growth-Promoting Rhizobacteria, can Promote Wheat Seed Germination by Gibberellin Pathway

The mechanism underlying seed germination promotion by plant growth-promoting rhizobacteria (PGPR) remains unclear. This study investigated the effects of Bacillus subtilis QM3 (a PGPR) and gibberellic acid (GA 3 ) on germination indexes, seedling growth, and amylase activity in wheat seeds ( Tritic...

Zusammenfassung:The mechanism underlying seed germination promotion by plant growth-promoting rhizobacteria (PGPR) remains unclear. This study investigated the effects of Bacillus subtilis QM3 (a PGPR) and gibberellic acid (GA 3 ) on germination indexes, seedling growth, and amylase activity in wheat seeds ( Triticum aestivum L.) (caryopses) at different germination times. The results showed that B. subtilis QM3 exhibited a significantly greater increase in most measured indicators compared to GA 3 ( p
