Abstract

Fresh flowers of cut lily plants often have a long postharvest life, but this changes after cold storage, which is often an essential process in the horticultural industry. In many cut lilies, a relatively short period of cold storage of 1 week often leads to early leaf and flower senescence. Early leaf and flower senescence are likely ethylene-dependent, either due to a higher level of ethylene production or a change in ethylene sensitivity. Such changes could be due to alteration in the expression of ethylene biosynthesis, perception, and signalling genes. Brassinosteroids (BRs) can delay the onset of senescence and chilling injury in crops but their effects on chilling tolerance in cut fl..
