another ‘benefits of CO2’ on plant growth … even with saline stresses

Considerable science experiments with the use of elevated atmospheric CO2 show considerable benefits in plant growth, salinity tolerance and reduced moisture requirements. This is sensational news to farmers and horticulturalists. The surprise is the ability of plants to thrive with much higher levels of salt in their environment when subjected to elevated CO2 levels:

Interactive Effects of CO2 and Salinity Stress on Plant Growth — Summary (15 July 2015)
A review of the scientific literature that describes the findings of scientists who have done both laboratory and field research on the effects of atmospheric CO2 enrichment of plants suffering from salinity stress reveals the significant magnitude of the ameliorating effects of this most welcome phenomenon…

Read about the many studies published at the link. Even more, bacterial pathogens are foiled through elevated CO2 in tomato growing. More Gas please: Atmospheric CO2 Enrichment Helps Foil Foliar Bacterial Pathogens (15 July 2015)


And it does so in tomato plants not only by reducing the stomata-mediated entry of P. syringae into their leaves, but by providing an additional means of counteracting the foliar bacteria…

I guess our bush tomatoes will fare well then.
