Abstract

The effects of different N level in combination with organic fertilizer on carotenoids, phenols and flavonoids contents in tomato fruits were studied. The N mixed with organic fertilizer treatment had higher the content of β- carotene, and AN2 achieved 34.20 μg/g. At red ripening stage, the content of lycopene of BN1 and BN2 were very close to, respectively 180.79 μg/g and 182.50 μg/g. The content of lutein at red ripening stage was nearly three times than that at turning stage. At red ripening stage, content of lutein ranged from 2.85 μg/g to 8.87 μg/g. In the all of phenolic acid, coffeic acid was the highest levels. The highest caffeic acid content (73.74 μg/g) was observed in the AN2 (double N and organic fertilizer), and only organic fertilizer (AN0) was no significant difference with BN1 (single N). Rutin content in tomato fruit had no difference in three N levels (N0, N1, N2). AN0 had the highest quercetin content in tomato fruits in all treatment, by 66.39 μg/ g.
