If plums were manually picked, cold storage was restricted to 4 weeks, irrespective of 1-MCP treatment (Figs. 2 and 3). If plums were mechanically harvested,cold storage was restricted to 2 weeks, irrespective of 1-MCP treatment (data not shown). Longer storage of manually picked fruit resulted in greater bruising, whereas longer cold storage of mechanically harvested European plums induced fruit bruising and softening (data not shown). In the present experiment, plums with Shore values of 60 appeared sufficiently firm for fresh fruit consumption. Flesh discolouration, which was not due to mechanical harvest, was probably caused by low temperature damage at 2 ℃ and corresponds to the softening after 3 weeks in cold store.
A respiration rate of 32 mg O2 per kg fresh mass h-1 at 20 ℃ (Fig. 6) was obtained for the European plum 1 day after harvest. This rate compares more favourably with 13–46 mg CO2 at 20 ℃ in climacteric rather than with the 9–15 mg CO2 kg fresh mass h-1 in ‘suppressed-climacteric’ Japanese (P. salicina L.) plums (Abdi et al., 1998). This is in support of classifying the European plum P. domestica L as a climacteric fruit, confirmed also by a respiratory climacteric in the cold store at 2 ℃
The initial RQ of ca. 1.1 in the first few days after harvest (Fig. 7) appeared largely unaffected by storage conditions (storage temperature), as expected, and is partly attributed to CO2 refixation (Blanke, 1991).The subsequent increase in RQ to 1.5 may indicate increasing usage of malic acid as respiratory substrate (Biale, 1960; Blanke, 1991) at the higher temperature.
The dramatic reduction of 50% in fruit respiration by 1-MCP during the first week in cold storage at 2 ?C resembles that of also ca. 50% found for climacteric Japanese plum cv. ‘Royal Zee’ during shelf life at 20 ?C by Dong et al. (2002) and the 65% reduction of several Japanese plum cultivars (15–28 mg CO2 kg?1 h?1) directly after harvest and 1-MCP treatment at 20 ?C (Abdi et al., 1998). Our ob-served 50% reduction in respiration (Fig. 5), however, was temporary and lasted only 1 week of cold storage, indicating independent effects of 1-MCP on ethylene
or respiration.
The positive effect on fruit mass and ethylene synthesis of 1-MCP before, but not after mechanical harvest (Fig. 1, Fig. 8), is attributed to blocking the ethylene receptors before the fruit starts to synthesise ethylene (Sisler et al., 1996) and also explains the observed initial 50% reduction in fruit respiration, while new receptors may later become available. This positive effect also supports the idea of a (potential) tree rather than post harvest application of 1-MCP.
