Fig. 1From: Green nanopriming: responses of alfalfa (Medicago sativa L.) seedlings to alfalfa extracts capped and light-induced silver nanoparticlesThe UV-visible spectra of different reaction conditions. A the sediment at different centrifugal rotational speeds; B the alfalfa extracts (water: extracts =1:1) and the supernatant at different centrifugal rotational speeds; C the sediment at different reactants ratios (2mM AgNO3: extracts); D the alfalfa extracts (water: extracts=1:2) and the supernatant placed in the dark for different time; E the sediment placed in the dark for different time; F the sediment placed under the light for different timeBack to article page
