Abstract
|
|
|
|
Cut Cymbidium flowers showed an increase in ethylene production as temperature was elevated from 3℃ to 23℃ and senescent stages were progressed at a given temperature. The stronger force the flowers received, the more the ethylene produced during the simulated vibration. Moreover, decapped or emasculated flowers produced it even more than untreated flowers. AVG treatment prior to the vibration lessened the rise in ethylene production. Application of naphthaleneacetic acid (NAA), S-abscisic acid (ABA), and propyl-dihydro jasmonate (PDJ) to the florets resulted in enhancing the time of lip coloration, while florets pretreated with AVG did not exhibit such an enhancement.
