Many cut flowers are treated with an ethylene action inhibitor, silver thiosulfate (STS), to delay senescence and are shipped by dry transport that involves relatively easy loading. In addition, cut flowers are often treated with a mixture of sugar and germicide to improve their vase lives. Exogenous treatments of these compounds or drying by transport are thought to have various effects on cut flowers. This study investigated the effects of these post-harvest management methods on the scent emission of carnation (Dianthus caryophyllus L.) cut flowers. Under all the management conditions, the total scent emissions of cut flowers were highest on harvest days and then decreased, but major changes in their compositions were not observed. The decreases in scent emissions were thought to occur earlier than the known ethylene induction in carnation cut flowers, which is equivalent to the 4th day after harvest. The STS treatment had no effect on the scent emissions for some time after harvest, but suppressed the decreases in scent emission 4–8 days after harvest under the wet transport condition. It is likely that the decreases in scent emissions in carnation cut flowers occur in an ethylene-independent manner, but ethylene induction a few days after harvest further promotes decreases under wet transport conditions. STS may have suppressed the promotion of decreases due to ethylene. On the other hand, the treatment that assumed dry transport for one day dramatically promoted the decreases in scent emissions. Since the promoting effects were not affected by the STS treatment, they were considered to be ethylene-independent. A common sugar treatment with 1% glucose, sucrose, or fructose did not affect the scent emissions in the cut flowers. An isothiazolinonic germicide, which is a common cut flower germicide, did not affect the treatment. Considering the current post-harvest process, the duration of a noticeable scent in carnation cut flowers can be expected to be extended by adopting wet transport instead of dry transport.

许多切花都用乙烯作用抑制剂硫代硫酸银 (STS) 处理以延缓衰老，并通过相对容易装载的干运运输。此外，切花通常用糖和杀菌剂的混合物处理，以改善它们的花瓶寿命。这些化合物的外源处理或运输干燥被认为对切花有各种影响。本研究调查了这些收获后管理方法对康乃馨 ( Dianthus caryophyllus)气味散发的影响。L.) 切花。在所有管理条件下，切花的总香味排放量在收获日最高，然后下降，但其成分没有发生重大变化。气味排放的减少被认为比康乃馨切花中已知的乙烯诱导发生更早，这相当于收获后的第 4 天。STS 处理在收获后的一段时间内对气味排放没有影响，但在湿运输条件下抑制了收获后 4-8 天气味排放的减少。康乃馨切花气味排放的减少可能以与乙烯无关的方式发生，但收获后几天的乙烯诱导进一步促进了湿运输条件下的减少。STS 可能抑制了由于乙烯导致的下降。另一方面，假设干燥运输一天的处理显着促进了气味排放的减少。由于促进作用不受 STS 处理的影响，因此它们被认为与乙烯无关。用 1% 葡萄糖、蔗糖或果糖进行普通糖处理不会影响切花中的气味散发。异噻唑啉酮类杀菌剂是一种常见的切花杀菌剂，对处理没有影响。考虑到目前的收获后过程，通过采用湿式运输而不是干式运输，可以预期延长康乃馨切花中明显香味的持续时间。它们被认为是不依赖乙烯的。用 1% 葡萄糖、蔗糖或果糖进行普通糖处理不会影响切花中的气味散发。异噻唑啉酮类杀菌剂是一种常见的切花杀菌剂，对处理没有影响。考虑到目前的收获后过程，通过采用湿式运输而不是干式运输，可以预期延长康乃馨切花中明显香味的持续时间。它们被认为是不依赖乙烯的。用 1% 葡萄糖、蔗糖或果糖进行普通糖处理不会影响切花中的气味散发。异噻唑啉酮类杀菌剂是一种常见的切花杀菌剂，对处理没有影响。考虑到目前的采收后流程，通过采用湿式运输而非干式运输，预计可以延长康乃馨切花中显着香味的持续时间。
