Abstract

The respiration intensity of Dendrocalamopsis oldhami shoots pretreated by 3 different methods(1 is boxed atconstanttemperature, 2 is pre-cooling in icewaterfor2 h, then stored in the thermal container, 3 is pre-cooling in ice water for 2 h, daubed by 10 mgkg- 1 chitose, then stored in the thermal container) in 20 h and 7 dayswas tested. The results showed that the respiration rate would increase quickly if the shootswere stored in the normal temperature and reach the peak value in 4- 6 h, which was 163.81 mgkg- 1h- 1CO2; the respiration rate would reach the peak in 14- 16 h if the shootswere stored in the ice water, whichwas 138.66 mgkg- 1h- 1 CO2; the respiration rate would reach the peak in 14 h if the shoots were pre-cooling in the ice water and treated with 10 mgg- 1 chitose, which was 113.43 mgkg- 1h- 1 CO2. Shoots pretreated with ice water and 10 mgg- 1 chitose would maintain a lowrespiration rate within 7 days. Therefore, such treatment could restrain the respiration of shoots.[Ch, 2 fig. 8 ref.]
