Scientists from the Ural Federal University and their Indian colleagues enriched microgreens (peas, mung bean, salad mustard, wheat) with minerals by infecting them with special rhizosphere bacteria. At the same time, plant growth increased. UrFU told socialbites.ca.
The addition of rhizosphere bacteria led to an increase in plant biomass and the content of photosynthetic pigments in it, for example, in pea microgreens, by 15-36%, as well as the accumulation of beneficial elements such as nitrogen, phosphorus, potassium , zinc and iron.
“Intravital enrichment of plants with macro- and microelements can become one of the strategies to combat ‘hidden hunger’ when the human diet contains sufficient calories but lacks vitamins and mineral compounds,” a professor at the Department of Experimental Biology and Biotechnology told UrFU socialbites.ca Galina Borisova.
Enriched microgreens will be useful for vegetarians, as well as residents of the Urals and other regions of Russia, to compensate for the lack of useful elements in the diet.
Rhizosphere bacteria are safe for both plants and humans. They settle in the roots of plants and interact with them. In addition to the effects described above, such symbiosis makes plants more resistant to abiotic and biotic stresses.
Scientists believe that these bacteria could be an alternative to chemical fertilizers and pesticides.
