| Abstract: | "We examined the effects of different amounts of nutrient solution supply on the yield, quality and volatile substances of tomato fruit by substrate cultivation. Using tomato cultivar 'HL2109' as experimental material, four treatments were set, including Control: irrigating with 117 L pure water for each plant; T(1): irrigating each plant with 39.0 L of nutrient solution; T(2): irrigating each plant with 58.5 L of nutrient solution; T(3): irrigating each plant with 117 L of nutrient solution. The quality and volatile substances of tomato fruits were determined by using chemical method and SPME-GC-MS technique. The results showed that the yield per plant and the gross production increased and then decreased with the increases of nutrient solution supply. The yield of T(2) was the highest among all treatments. The yields of T(1), T(2) and T(3) were 29.3%, 72.6% and 47.0% higher than that in Control, respectively. The irrigation water use efficiency of T(1) was the highest and T(2) took second place, though the difference being not significant. The soluble solids content and sugar acid ratio of tomato fruits in T(2) were the highest, and the flavor and quality were significantly improved. The content of ascorbic acid and soluble protein gradually increased with the increases of nutrient solution supply. The contents of total soluble sugar and reducing sugar were first increased and then decreased, both being highest in T(2). Using GC-MS analysis, a total of 69 volatile compounds were detected. The total content of volatile compounds from T(1), T(2) and T(3) were higher than that in Control, which presented as T(2)??-T(1)??-T(3)??-CK. Among them, the content of volatile compounds from T(2) was 6971 mug.kg(-1), which was 1.97 times higher than that in the Control. The content from T(3) was 4070 mug.kg(-1), being 0.73 times of that in the Control. The contents of 1-Pentene-3-one, 6-Methyl-5-hepten-2-one, hexanal, hexanoic acid, Phenylacetaldehyde and cis-3-hexenal were highest in T(2) among all treatments. Moreover, the content of characteristic volatile compounds, the quantity and total content of volatile compounds were highest in T(2). Taken together, the T(2) treatment (irrigating each plant with 58.5 L of nutrient solution) had the best effects, with the quality and content of volatile compounds in tomato fruit being improved" |
