Seed priming with cold plasma improved seedling performance, secondary metabolism, and expression of deacetylvindoline O‐acetyltransferase gene in Catharanthus roseus

The plasma‐primed seeds of Catharanthus roseus were cultured in a hormone‐free culture medium under sterile conditions. Plasma of 30 or 60 s improved root length (mean = 41.4%) and biomass (mean = 47%), whereas plasma of 90 s delayed plant growth. The plasma treatments enhanced concentrations of pho...
