番茄不同果穗间品质性状差异性研究

Study on Tomato's Quality and Traits at Different Tassel

以30个番茄品种为试材,最终筛选6个最具代表性的品种,测定不同果穗的可溶性固形物、可溶性糖、可滴定酸含量,并计算糖酸比,研究不同果穗间番茄果实品质性状的差异。结果表明:不同番茄品种在外观品质以及大部分生理指标上存在相似的规律;外观品质上,所有供试品种的第3、4穗果实较其它果穗果实果色更均匀,大小更适中,果实形状更符合品种特性;在生理指标上,所有供试品种第3、4穗果实的可溶性固形物和可溶性糖的含量均高于其它果穗果实,且糖酸比适中,但可滴定酸含量的变化规律不明显。

With 30 tomato varieties as test materials, screening for six most representative varieties to determination tomato fruits~ soluble solid content, soluble sugar, titratable acidity and sugar-acid ratio at different tassel, quality traits at different tassel tomato fruits were studied. The results showed that there were similar laws on different tomato varieties in appearance quality and most physiological indicators. In appearance quality, all tested cultivars 3,4 tassel tomato fruits ＇ color and size were more uniform than the others, its shape was more in line with species characteristic. In physiological indicators,all tested cultivars 3,4 tassel tomato fruits＇ soluble solid content and soluble sugar content were higher than the others and its sugar-acid ratio was moderate. But the change of titratable acid content was not obvious regularity.
