Cyanide-resistant respiration and its role of Paeonia lactiflora cut flowers during storage time

This article is a report dealing with the studies on cut flowers of Paeonia lactiflora ‘Lian Tai’ and ‘Taohua Feixue’.Cyanide-resistant respiration rate and some physiological characters of the two cultivars were investigated during dry storage under 0-2℃.The results show that the enhancement of cyanide-resistant respiration rate during storage time is helpful for lowering the level of \rmO_2^\rm\bar \cdot, then maintaining the vase life after storage.The enhancement of \rmO_2^\rm\bar \cdot production rate has inducing effects on the cyanide-resistant respiration rate.The different storage stability of cultivars has relations with the changes of cyanide-resistant respiration rate, the cultivars whose cyanide-resistant respiration rate increasing steadily during storage time have good storage stability.
