e0“2 mM PUT treatment also had the greatest effect on increasing fresh and dry biomass, number and surface area of leaves, flower diameter, internodal length, leaf relative water content, protein contents, total chlorophyll contents, carotenoids, leaf potassium (K + ) content, and K + /Na + ratio in treated plants compared to untreated control plants”
e1“Zinnia elegans “State Fair” flowers”
e2“PUT treatments effectively recovered the decrease in plant height and flower quality compared to the not-treated plants”
e3“treated plants compared to untreated control plants”
