摘要
为研究外源性物质叶面喷施对番茄产量、表观性质及有益成分的影响,在温室大棚内种植粉色番茄,研究KCl、Mn2+、脱落酸及三者混合液叶面喷施对番茄果实品质的影响,并测定番茄产量和果实大小,以及番茄红素、可溶性糖、维生素C和有机酸等可溶性固形物的含量差异。结果表明,叶面喷施外源性物质对果实大小和品质具有积极作用,特别在可溶性固形物的含量方面促进作用尤为突出,而喷施三者混合液的处理对果实可溶性固形物含量累积的促进作用最为显著,增量为32.09%。然而,不同外源性物质的喷施对果高、单株产量以及番茄红素、维生素C、有机酸含量影响不显著,而对番茄果实直径、单果重和可溶性糖的积累存在显著差异。
In order to investigate the effect of foliage spraying exogenous materials on the apparent properties and quality of tomato fruits, the experiment of tomato cultivation in solar greenhouse was conducted using KCl,MnSO4, abscisic acid(ABA) and the above 3 kinds of mixture solution as the foliage spraying exogenous materials. The yield, size and the content of lycopene, soluble sugar, vitamin C and organic acid in tomato fruits were detected after the experiment. The results showed that the exogenous materials spraying could dramatically approve the quality and size of tomato fruits, especially the content of soluble solids. However, the mixture of KCl, MnSO4 and ABA addition could be significantly improved the soluble solids content in tomato fruits with increment of 32.09%. In addition, different exogenous materials had no significant influence on fruit height, yield per plant, lycopene, vitamin C and organic acid, but it significantly influenced the fruit diameter,fruit weight and soluble sugar of tomato fruits, respectively.
