STUDIES ON POSTHARVEST PHYSIOLOGY OF CHINESE CHIVE SCAPES |
| Author: | P. Wu |
| Abstract:
The flower opening rate of Chinese chive scapes can be above 50% after 18 days storage at 10°C. It has been confirmed that flower opening is one of the main factors that cause senescence. Endogenous IAA levels decrease and ABA levels increase during flower opening and senescence during storage. The optimum storage temperature for Chinese chive scapes is about 3°C. Applications of exogenous 2,4-D or GA3 can decrease the rate of flower opening, which can be reduced to less than 50% of the control. These treatments can also change the levels of endogenous hormones and delay senescence. Film wrapping is effective for maintaining freshness of Chinese chive scapes, especially with the use of polypropylene film. By using the polypropylene filn1, loss from decay and flower opening could be reduced to less than 1% after 26 days of storage at 3°C. | |
