Effects of Ethylene on the Post-Production of Potted Ornamental Peppers (Capsicum Annuum L.)

Ethylene, 1-methylcyclopropene and silver thiosulfate on the post-production of ornamental pepper

“…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).…”

“…Sensitivity of ornamental plants to ethylene is roughly established at family level, but marked differences exist among species and cultivars (SEREK et al, 2006). Previously SEGATTO et al (2013) reported that genotypes of ornamental pepper BGH 1039, BGH 7073, 'Calypso' and 'MG 302' had different levels of sensitivity to ethylene, in which the cultivar 'Calypso' and access BGH 1039 were classified as highly sensitive. The authors reported that ethylene unleashed a severe and rapid abscission of leaves for 'Calypso', but the cultivar 'MG 302' showed intermediate response to treatment, with abscission ranging from 15 to 38% after being exposed to 10µL L -1 ethylene for 48 hours.…”

“…When commercial stage for sale was reached, according to RIBEIRO et al (2015), 50% of the plants in a population showed at least 30% of fully ripe fruits (typical shape for each material, color demanded by the market, and no wilting). Afterwards, the pots were transferred to a room at 25+1 o C, illuminated for 12 hours period with white fluorescent light (OSRAM, L40W/10S, USA) with intensity of 8-10µmol s -1 m -2 during the experimental period (SEGATTO et al, 2013).…”

“…Pots were then placed in a 90L sealed chambers for 1-MCP and ethylene treatment, according to the methodology of SEGATTO et al (2013). Plants of all treatments were kept at 25±1°C under white fluorescent light with intensity of 8-10µmol s -1 m -2 , 60-65% relative humidity and watered when needed (FINGER et al, 2015).…”

“…However, there are serious obstacles affecting the quality and shelf life of ornamental potted plants or at post-production phase, with special attention to adverse effects when exposed to ethylene (HOYER, 1996;SEGATTO et al, 2013).…”
