The influence of spectral light on leaf quality and phytochemical contents and composition of aroma compounds in coriander leaves grown for fresh use under photo-selective nets; pearl net [40% shading; and 3.88 blue/red ratio; 0.21 red/far red ratio; photosynthetic radiation (PAR) 233.24 (mu mol m(-2) s(-1))] and red net [40% shading and 0.57 blue/red ratio; 0.85 red/far red ratio; 221.67 (mu mol m(-2) s(-1))] were compared with commercially used black nets [25% shading; 3.32 blue/red ratio 0.96 red/far red ratio; 365.26 (mu mol m(-2) s(-1))] at harvest and after 14 days of storage. Black nets improved total phenols, flavonoid (quercetin) content, ascorbic acid content, and total antioxidant activity in coriander leaves at harvest. The characteristic leaf aroma compound decanal was higher in leaves from the plants under the red nets at harvest. However, coriander leaves from plants produced under red nets retained higher total phenols, flavonoids (quercetin) and antioxidant scavenging activity 14 days after postharvest storage (0 degrees C, 10 days, 95% RH and retailers' shelf at 15 degrees C for 4 days, 75% RH). But production under the pearl nets improved marketable yield reduced weight loss and retained overall quality, ascorbic acid content and aroma volatile compounds in fresh coriander leaves after postharvest storage. Pearl nets thus have the potential as a pre-harvest tool to enhance the moderate retention of phytochemicals and saleable weight for fresh coriander leaves during postharvest storage.
