Bio-priming is a new technique of seed treatment that improves seed germination, vigor, crop growth and yield. The objective of this study was to evaluate the effectiveness of (commercial strains) and (newly isolated strains) as a single inoculant and co-inoculant during seed bio-priming to improve seed germination and initial seedling growth of two soybean cultivars. The treated seeds were subjected to germination test (GT), cold test (CT) and accelerated aging test (AAT). significantly improved all parameters in GT and CT; final germination, shoot length, root length, root dry weight, and seedling vigor index in AAT, as compared to control. In addition, co-inoculation significantly increased all parameters except shoot dry weight in GT; all parameters in CT; germination energy, shoot length, root length, and seedling vigor index in AAT, in comparison to the control. Moreover, significantly improved the germination energy, shoot length, shoot dry weight, root dry weight, and seedling vigor index in GT; all parameters in CT; shoot length, root length, and seedling vigor index in AAT, compared with non-primed seeds. Thus, strains could be used in soybean bio-priming as a potential single inoculant and co-inoculant, following proper field evaluation.
生物引发是一种种子处理新技术，可提高种子发芽率、活力、作物生长和产量。本研究的目的是评估（商业菌株）和（新分离菌株）作为单一接种剂和共接种剂在种子生物引发过程中对两个大豆品种种子发芽和幼苗初期生长的促进效果。对处理后的种子进行发芽试验（GT）、冷试验（CT）和加速老化试验（AAT）。与对照相比，在GT和CT中显著改善了所有参数；在AAT中，最终发芽率、苗长、根长、根干重和幼苗活力指数均有提高。此外，与对照相比，共接种显著提高了GT中除茎干重外的所有参数；CT中的所有参数；AAT中的发芽势、苗长、根长和幼苗活力指数。此外，与未引发种子相比，在GT中显著提高了发芽势、苗长、茎干重、根干重和幼苗活力指数；CT中的所有参数；AAT中的苗长、根长和幼苗活力指数。因此，经过适当的田间评估后，这些菌株可作为潜在的单一接种剂和共接种剂用于大豆生物引发。
