“…Confirming the high sensitivity of 'Calypso' leaves to ethylene previously identified by SEGATTO et al (2013) andFINGER et al (2015). The sensitivity of ornamental plants to ethylene was roughly established at family level, but marked differences exist among the species and cultivars (SEREK et al, 2006).…”

“…Thus, pretreating these peppers with 1-MCP or STS complements the resistance to ethylene, but did not reduce the sensitivity to its action, once the treatment is completed. It has been suggested that only by incorporating genes of resistance in new cultivars it will be possible to improve the longevity of ethylenesensitive ornamental plants (FINGER et al 2015).…”

“…Longevity and yellowing of the leaves were determined at every three days up to 18 days. The end of longevity occurred when the plants did not have commercial value, 50% of leaf and fruit abscission and/or 50% yellowing of leaves (FINGER et al 2015).…”

“…According to FINGER et al (2015), in order to improve post-production life, it is necessary to block the ethylene receptors before exposing the plant to ethylene during shipping, storage and retail stores or when plants are submitted to any stress that might induce ethylene production. There are several problems Lima et al encountered at post-production stage that affect the quality and vase life of ornamental plants, but in general the exposure to ethylene is one of the most important.…”

Species from Capsicum genus are used for different purposes and in more recent years as ornamental potted plant. Despite the increased commercial importance, there are only a few studies on the environmental factors affecting the post-production shelf life of these ornamental plants. The presence of ethylene induces various responses on potted peppers, reducing the shelf life of sensitive cultivars. This study aimed to evaluate the effects of ethylene and the inhibitors of ethylene action, 1-methylcyclopropene (1-MCP) and silver thiosulfate (STS) on the shelf life of potted 'Calypso' and 'MG 302' peppers. Cultivar 'MG 302' showed intermediate sensitivity to ethylene action, while the cultivar 'Calypso' showed complete abscission of leaves when exposed to ethylene. In both cultivars, treatment with STS + Ethylene presented symptoms of phytotoxicity in plants, while treatment with 1-MCP + Ethylene was effective in delaying senescence and abscission for the cultivar 'MG 302', while cultivar 'Calypso' showed abscission similar to control plants. Plants treated with STS showed the longest durability when compared to the other treatments, about six days for 'Calypso' and 18 days for 'MG 302'. Nevertheless, plants treated with 1-MCP also exhibited good shelf life, about six days for 'Calypso' and nine days for the 'MG 302'. Although the treatment with STS was more efficient on the plants shelf life, did not completely block the action of ethylene and exhibited some phytotoxicity, while the treatment with 1-MCP had good efficiency without inducing any toxicity.

The species of Capsicum genus have great genetic variability with enormous potential for marketing as ornamental potted plants. The exposure at ethylene induces various deleterious responses during plants life cycle, but there are few studies on how the ethylene affects early developmental stages of these ornamental plants. Thus, this study aimed to evaluate the effects of the application of ethylene and ethylene inhibitors, 1-methylcyclopropene (1-MCP) and silver thiosulphate (STS) in two early development stages (seedling or initial flowering) of potted ornamental peppers of the cultivars ‘Calypso’ and ‘MG 302’. Cultivar ‘MG 302’ showed intermediate sensitivity to ethylene, while the cultivar ‘Calypso’ showed complete abscission of leaves when exposed to 10 µl of ethylene for 48 hours in both development stages. Plants treated with 1-MCP showed similar durability to control for both varieties and developmental stages, and the treatment with 1-MCP + ethylene was beneficial only for ‘MG 302’. STS was the most efficient substance in delaying the ethylene, wherein at stage 1 there was no leaf abscission and at stage 2 had much reduced leaf abscission occurred, regardless the cultivar. Treatment with STS + ethylene was efficient only at stage 1 for ‘Calypso’ and at stage 2 for ‘MG 302’. According to the data, cultivars showed different levels of sensitivity to ethylene, ‘Calypso’ is very sensitive and ‘MG 302’ showed intermediate sensitivity. Regardless the cultivar, STS treatment significantly blocked the ethylene action in both development stages and the use of 1-MCP was less efficient
