Harvest and Post-Harvest Performance of Autumn-Winter Butterhead Lettuce as Affected by Nitrogen and Azoxystrobin Application

نویسندگان

چکیده

An autumn-winter trial was carried out in Southern Italy open-field conditions on butterhead lettuce to investigate the effect of nitrogen (N) fertilizer rate (0, 50, and 100 kg ha−1, N0, N50, N100) application azoxystrobin, sprayed twice an earlier vs. a later scheme, specifically at 65/85 or 65/100 days after transplantation. untreated control also included. The evaluation product quality conducted fresh stored shredded leaves. N50 suitable for lettuce, but it does not guarantee color appearance leaves (lowest h°, highest L*). Concerning post-harvest changes, N50- N100-product were less storage, accounting higher decay visual (h°) physiological senescence (EL) indices. Irrespective N time, azoxystrobin improved growth yield (+16%), (lower L*, chlorophylls), nutritional (higher carotenoids antioxidant capacity) shelf-life leaves, by keeping turgidity (RWC), lower (CHLs, h°), value (carotenoids), limiting browning spreading
