摘要
以番茄‘浙杂204’Lycopersicon esculentum‘Zheza 204’为试材,采用基质盆栽,研究了限根栽培对番茄植株生长、果实产量、品质及转色期的影响。结果表明:限根栽培抑制了番茄植株的生长,株高、茎粗均下降,且随着生长期延长抑制作用愈加明显,在前后2次生长测定中,1 L容器栽培植株株高和茎粗分别为7 L容器栽培的80.06%,80.06%和50.06%,77.48%;限根栽培下果实品质提高,可溶性固形物、番茄红素和可滴定酸的含量提高幅度最高分别可达18.72%,50.67%和49.28%,对维生素C质量分数的影响较小;限根栽培还推迟了番茄果实的始红期,而终红期与对照比较一致,转色时间缩短,降低了产量。总之,限根栽培抑制了番茄植株生长,改善了果实品质,缩短了转色时间,同时产量有一定程度的下降。
The effects of root restriction on Lycopersicon esculentum ＇Zheza 204＇（tomato）plant growth,fruit yield,quality,and color-changing period in a substrate culture with 1,3,5,and 7 L cubage pots（7 L treatment served as a control） were studied.Results showed that root restriction inhibited plant growth,plant height,and stem thickness with an increase in inhibition as growth period increased.At the first measurement plant height and stem thickness cultured in 1 L pots were both 80.06% of those in the 7 L pots,but at the second measurement in 1 L pots plant height was 50.06% and stem thickness was 77.48% of the 7 L pots.With root restriction fruit quality increased,namely soluble solid content（18.72%）,lycopene content（50.67%）,and titratable acid content（49.28%）.However,root restriction did not have a strong effect on vitamin C content.Root restriction also delayed initiation of the fruit color-changing period;whereas completion of the color-changing period was consistent with the control meaning that the total color-changing period was shortened.In addition,yield decreased with root restriction.Thus,root restrictions inhibited plant growth,improved fruit quality,shortened the color-changing time,and at the same time,reduced fruit yield.[Ch,7 fig.1 tab.23 ref.]
