| סיכום: | The effects of stress factors associated with climate change and agricultural
management practices on microorganisms are often studied separately, and
it remains to be determined how these factors impact the soil microbiome
and, subsequently, plant growth characteristics. The aim of this study was to
understand how the historical climate and agriculture to which soil microbes
have been exposed can influence the growth characteristics of wheat seedlings
and their associated bacterial communities. We collected soil from organic
and conventional fields with different histories of climate conditions to extract
microbes to inoculate wheat seeds under agar-based cultivation conditions.
Within a growth period of 8 days, we monitored germination rates and time
as well as seedling above-ground biomass and their associated bacterial
communities. The results showed a positive interaction between conventional
farming practices and an ambient climate for faster and higher germination
rates. We demonstrate that soil microbial extracts from organic farming with
experience of the future climate significantly enhanced above-ground biomass
along with the diversity of bacterial communities associated with seedlings
than other treatments. Such findings support the idea that organic agricultural
practices not only mitigate the adverse effects of climate change but also
promote the diversity of seedling-associated bacteria. |
