安徽沿江地区设施高品质番茄品种筛选试验

Screening Test of High Quality Tomato Varieties in Protected Areas along the Yangtze River in Anhui Province

以托鲁巴姆为砧木,21份番茄为接穗,采用劈接法进行嫁接,定植后通过对果实性状、营养品质指标、产量和抗病性进行比较,筛选出适合安徽沿江地区设施栽培的高品质番茄,以期为填补长三角地区蔬菜市场伏缺与秋淡提供数据支撑。结果表明,T-05的果形指数为1.14,果实形状较圆。T-19的维生素C含量最高,为41.713 mg/kg,与其他20份番茄相比具有显著差异(P<0.05)。T-02的总糖含量最高,达78.432 mg/g,显著高于其他20份番茄。T-01的番茄红素含量达51.959μg/g,T-13的番茄红素含量最低,仅为19.961μg/g。T-01的可滴定酸含量在21份番茄中最高,为0.508%,显著高于其他20份番茄,T-17的可滴定酸含量最低,为0.224%。T-04和T-06的可溶性固形物含量分别达9.2%和9.3%,T-11的糖酸比最高,为293.43,T-19的糖酸比最低,为136.58。综合考虑筛选出3个适合安徽沿江地区设施栽培的高品质番茄品种,其中T-01为中果型番茄,果色为粉红色,果实纵径56.01 mm,果实横径66.21 mm,心室数3个,其可溶性固形物含量达6.6%。T-04和T-06为小果型番茄,其中T-04果色为粉红色,果实纵径32.08 mm,果实横径34.97 mm,心室数2个;T-06果色为大红色,果实纵径30.11 mm,果实横径33.37 mm,心室数2个,其可溶性固形物分别达9.2%和9.3%。

In this experiment,torubam was used as rootstock and 21 tomatoes as scions,which were grafted by split grafting method.After planting,through the comparison of fruit characters,nutritional quality indexes,yield and disease resistance,high-quality tomatoes suitable for facility cultivation along the river in Anhui were selected,in order to provide data support for filling the potential shortage and autumn light of vegetable market in the Yangtze River Delta.The results showed that the fruit shape indexes of T-05 was 1.14,and its fruit shapes was round.The vitamin C content of T-19 was the highest,41.713 mg/kg,which was significantly different from that of other 20 tomatoes(P<0.05).The total sugar content of T-02 was the highest,reaching 78.432 mg/g,which was significantly higher than that of other 20 tomatoes.The lycopene content of T-01 reached 51.959μg/g,the content of lycopene in T-13 was the lowest,only 19.961μg/g.The titratable acid content of T-01 was the highest among 21 tomatoes with 0.508%,significantly higher than that of other 20 tomatoes,and the titratable acid content of T-17 was the lowest with 0.224%.The soluble solid contents of T-04 and T-06 reached 9.2%and 9.3%respectively.The sugar acid ratio of T-11 was the highest with 293.43,and the sugar acid ratio of T-19 was the lowest with 136.58.Through comprehensive consideration,three high-quality tomato varieties suitable for facility cultivation along the Yangtze River in Anhui Province were selected.Among them,T-01 is a medium fruit tomato with pink fruit color,56.01 mm longitudinal fruit diameter,66.21 mm transverse fruit diameter,3 ventricles,and its soluble solid content reaches 6.6%.T-04 and T-06 are small fruit tomatoes,of which T-04 fruit color is pink,the longitudinal diameter of fruit is 32.08 mm,the transverse diameter of fruit is 34.97 mm,and the number of ventricles is 2;T-06 is bright red in color,with a longitudinal diameter of 30.11 mm and a transverse diameter of 33.37 mm.It has two ventricles,and its soluble solids reach 9.2%and 9.3%respectively.
