摘要:

以金珠樱桃番茄为试材,研究采前杀菌剂喷施对采后樱桃番茄发病率、质量损失率和食用品质的影响,并测定樱桃番茄果实中啶菌噁唑残留变化。结果表明:采前喷施杀菌剂显著降低了金珠樱桃番茄采后发病率,提高了樱桃番茄果实中VC和可溶性固形物含量,减缓了VC和可溶性固形物含量贮藏期间的损失;但对质量损失率和可滴定酸含量的影响不显著(P<0.05)。对樱桃番茄采后贮藏保鲜效果最好的杀菌剂为啶菌噁唑,喷施质量浓度为0.4 g/L。采前喷施啶菌噁唑后,樱桃番茄中啶菌噁唑残留在采前和采后均呈下降趋势;且采后樱桃番茄中啶菌噁唑残留下降的速度比采前下降的慢,贮藏温度越低,下降越慢。

Abstract:

“Jinzhu” cherry tomato was used to investigate the effect of preharvest fungicide spraying on the incidence
of diseases, weight loss, eating quality and SYP-Z048 residues of postharvest fruits. The results showed that pre-harvest
fungicide spraying dramatically reduced the disease incidence of postharvest “Jinzhu” cherry tomato, increased the contents
of vitamin C and total soluble solids (TSS) and delayed their loss during postharvest storage, but did not significantly
affect weight loss and the content of TA (P < 0.05). The best pre-harvest fungicide was SYP-Z048 at a concentration of 0.4 g/L.
SYP-Z048 residues revealed a declining trend both in preharvest cherry tomato fruits and in postharvest ones, declining
slower in postharvest fruits. Moreover, lower storage temperature resulted in a slower declining rate.

Key words: preharvest fungicide spraying, cherry tomato, quality, SYP-Z048 residues
