Abstract ▼ AI-Helper

We investigated the effect of 1-methylcyclopropene (1-MCP) on ethylene production induced by simulated transport stress in $Begonia$ ${\times}$ $hiemalis$ 'Blitz' and 'Carnival' to improve the display life in potted plants. The simulated transportation conditions were imposed for 4 days in simulated export containers with darkness, vibration with continuous shaking ($150{\pm}20$ rpm) on a rotary lab shaker, and low temperature ($12^{\circ}C$). Plants were treated with 1-MCP at three concentrations (5, 25, or 125 $nL{\cdot}L^{-1}$) and for three different periods (0, 6, or 12 hours) before undergoing the simulated transport stress treatments. Treatment with 25 or 125 $nL{\cdot}L^{-1}$ 1-MCP inhibited the abscission of open flowers by more than 40% as compared to the untreated plants. One week after the treatments, the ethylene production decreased in the plants treated with 125 $nL{\cdot}L^{-1}$ 1-MCP for 'Blitz' and 25 $nL{\cdot}L^{-1}$ for 'Carnival'. Ethylene production was correlated with concentration and duration of 1-MCP treatment in 'Blitz', but not in 'Carnival'. To reduce flower abscission and ethylene production, thus improve the display life when plants are exposed to transportation stress, we recommend pre-treatment with 1-MCP before packaging, using concentrations and durations specific to each cultivar, 125 $nL{\cdot}L^{-1}$ for 6 h and 25 $nL{\cdot}L^{-1}$ for 12 hours for 'Blitz' and 'Carnival', respectively.

문제 정의

Therefore, the objective of this study was to investigate the differences in display lives of begonia flowers after exposure to transportation stresses following pre-treatment with 1-MCP. We identified treatment conditions, such as concentration of and duration of exposure to 1-MCP that would most effectively improve the display life of Begonia × hiemalis.

제안 방법

, Anyang, Korea) fitted with a photoionization detector. A complete randomized design was used for the experiments and the experiments were repeated three times with ten replicates each. Statistically significant differences between mean values were assessed by Duncan’s multiple range test (P < 0.

대상 데이터

Potted flowering plants of Begonia × hiemalis ‘Blitz’ and ‘Carnival’ were obtained from a commercial grower at the bud stage (Goyang, Korea) and transported to the greenhouse at the experimental farm of the College of Agriculture and Life Sciences at Seoul National University in Suwon, Korea.

데이터처리

Statistically significant differences between mean values were assessed by Duncan’s multiple range test (P < 0.5% level) using SAS (SAS Institute Inc., Cary, NC, USA) for analysis.

성능/효과

In conclusion, pre-treatment with 1-MCP decreased bud and flower abscission, and ultimately extended the display life for Begonia × hiemalis varieties ‘Blitz’ and ‘Carnival’.
