). However, postharvest litchi is very fragile, which is mainly indicated by its susceptibility to mechanical injury ( Chen et al., 2014 ) and high decay rate ( Zhang and Quantick, 1997 ). The fragility of postharvest litchi has been given much attention by

Freshly harvested and graded tomatoes were held for 7 days at 21C in 1993 and 15.5C in 1994. After the holding period, the fruit were examined for decay development. In 1993, decay losses were not significantly different between cultural treatments, possibly due to a very warm and dry growing season. However, decay losses were significantly different during a wet 1994 growing season. Stake-grown fruit decay loss was 10.1% vs. 34.1% loss for ground culture. Losses due to anthracnose (Colletotrichum coccodes) was significantly higher on the ground culture fruit (8.7%) than on the stake culture fruit (0.5%). Sour/watery rot (Geotrichum candidum), Rhizopus soft rot (Rhizopus stolonifer), bacterial soft rot (Erwinia carotovora) and the black mold rot complex (Alternaria, Stemphylium, Pleospora) were the other predominant postharvest decays.

Plots set up on a commercial seed farm were supplemented with 0 or 168 Ca/ha supplied from liquid calcium nitrate at 3 and 6 weeks after hilling (84 kg Ca/ha per application). Paired measurements of tuber medullary tissue Ca concentration and decay severity after inoculation with Erwinia carotovora pv. atroseptica (Eca.) were taken on identical tubers from these separate plots of `Atlantic', `Superior', `Red Norland', and `Russet Burbank'. Fresh-cut seed pieces sprayed with a suspension of Eca. (108 cfu/ml) were planted in separate 1-liter containers filled with field soil maintained under two soil moisture regimes: 1) air-dry days 1–5, saturation days 6–10, field moisture capacity (FMC) days 11–18, or 2) FMC days 1–18. Containers were placed at 22C constant air temperature at the Univ. of Wisconsin–Madison Biotron. Decay severity (percent volume seed piece decay) and decay incidence (percent tubers with any decay) were rated after 18 days. Eight seed pieces per treatment were evaluated. The mean tuber Ca concentration was higher in plots receiving calcium compared to nonsupplemented plots. Mean medullary Ca concentration varied among cultivars as `Russet Burbank' > `Atlantic' > `Superior' > `Red Norland'. The influence of cultivar on decay showed an incidence and severity pattern `Atlantic' = `Russet Burbank' > `Superior' = `Red Norland'. Decay incidence and severity were greatest in seed pieces kept in temporarily saturated soil compared with those in soil maintained at FMC. Decay incidence and severity were ≈6% lower in tubers produced on Ca-supplemented soil. A scatter plot of decay severity × Ca concentration for seed pieces held at FMC suggests that a threshold of Ca concentration exists above which little or no decay occurs.
