Low light irradiation using red light emitting diodes and nutrient gel application for low temperature storage of postharvest chervil (Anthriscus cerefolium L.).

Chervil was stored at 8.0 deg C under low light irradiation (LLI, 1 micro mol m-2 s-1 photosynthetic photon flux density, PPFD) with nutrient gel application (NGA) to the cut ends of the stems. Low light was provided with an array of red light emitting diodes (red LEDs). Similar changes in chromaticity (L*, a*, b* and DELTA E*ab) values over 21 days of storage were observed compared with chervil stored at 6.8 deg under darkness with NGA. Chervil stored without NGA showed markedly greater values in L*, a* and DELTA E*ab after day 9 of storage compared with that stored with NGA, at 8.0 deg under LLI. LLI using red LEDs with NGA proved highly effective for preserving the visual quality of chervil during low temperature storage.
