Biochar as an alternative to improve the in vitro environment for Pitaya (Hylocereus undatus Haw) and strawberry (Fragaria x ananassa Duch) growing

March 2023

In vitro cultivation is widely used for micropropagation of several plant species; however, the increase in the gas concentration, such as ethylene gas, inside the growth vials can cause physiological changes. Thus, 4 experiments were carried out at the Federal University of Minas Gerais to evaluate the biochar use from sugarcane bagasse in vials with or without caps with porous membrane in the in vitro growing of...
