英文摘要	The Mediterranean long shelf-life tomato (or long storage tomato) is a plant traditionally cultivated under no irrigation in the Southern regions of Italy, whose fruits have typical high sensory and nutritional quality. However, yield levels are kept low under current cultivation conditions. In this study, the effects of repeated cycles of drying and rehydration on crop productivity and nutritional quality of fruits in terms of polyphenols and carotenoids content were assessed in long shelf-life tomatoes cultivated in a typical semi-arid area of Southern Italy. The three local Sicilian landraces 'Custonaci', 'Salina' and 'Vulcano', and the commercial tomato hybrid 'Faino' (control) were submitted to three irrigation treatments: DRY (no irrigation); IRR (long-season full irrigation); REW (drought/rewatering cycles). Total 450, 4710, and 1849 m(3) ha(-1), were distributed in DRY, IRR, and REW, respectively. At harvest, fruit yield, polyphenols (as total, flavonoids, and hydroxycinnamoyl quinic acids-HCQA), and carotenoids contents (lycopene and beta-carotene) were measured. All cultivars benefitted from very limited irrigation in REW, raising their productivity (up to +147% in 'Vulcano') with respect to that of plants overstressed in DRY. Irrigation water use efficiency in REW was higher than that in IRR. Water shortage in REW led to a polyphenols content of fruits that was slightly lower (171.1 mu g g(-1)) than that in DRY, but higher than that in IRR (116.8 mu g g(-1)). All local landraces had greater contents (> 160 mu g g(-1)) than control (113.0 mu g g(-1)). Under REW and DRY, the two landraces 'Salina' and 'Vulcano' produced fruits with the same polyphenols and flavonoids contents. Overall, the two water stressed treatments (DRY and REW) did not differ for HCQA content (> 66 mu g g(-1)), which was significantly higher than that in the irrigated plots (< 50.55 mu g g(-1)). Lycopene content in DRY and REW exceeded 100 mu g g(-1); among local types, 'Vulcano' exhibited the highest content (106.7 mu g g(-1)). The beta-carotene content did not change in 'Custonaci' and 'Salina', whereas in 'Vulcano' it was greater in DRY and REW. Only in 'Faino' water limitation in REW exerted a clear promoting effect on beta-carotene content of fruits. The results of the present study reveal how rewatering after long-lasting drought periods is beneficial to long shelf-life tomatoes in terms of productivity. Appropriate drought cycles in REW may also help the fruits to retain high nutritional levels.
