Some factors that contribute to poor survival of rhizobia on preinoculated legume seed

摘要: Preinoculation of seed is a convenient alternative method to inoculating on-farm. With preinoculation, range plant-growth and protection agents, polymer adhesives, colour pigments or dyes, powder materials may be incorporated into an inoculant adhesive-slurry prior coating. However, our recent point-of-sale surveys support findings previous studies that survival rhizobia on preinoculated variable can poor. We focussed research, both in the laboratory at commercial facilities, some factors contribute poor seed. found rhizobial was affected by water quality; filtration improved cell but not equal distilled water. also polymers differently for each strain, slowing desiccation rate reduced decline. Although fewer number, older afforded more cells. There need test ingredient stage seed-coating process compatibility determine best practices promote Failure act these prolongs status quo from retail surveys.
