Ethylene and the postharvest performance of miniature roses

Ethylene and the postharvest performance of miniature roses. Serek, M.; Sisler, E.C.; Reid, M. 3100-04-7 and 74-85-1 are cas registry numbers. These chemicals are also mentioned in this article.S. (Section for Horticulture, Department of Agricultural Sciences, The Royal Veterinary and Agricultural University, Copenhagen, Den.). Acta Horticulturae, 424(Second International Symposium on Roses, 1995), 145-149 (English) 1996 International Society for Horticultural Science. CODEN: AHORA2. ISSN: 0567-7572. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) The post-prodn. life of miniature rose plants is terminated by senescence of flowers, yellowing and loss of buds, and senescence and abscission of leaves. The presence of ethylene in the postharvest environment accelerates these symptoms. Treatment with silver thiosulfate (STS) prevents the effects of exogenous ethylene, but has less benefit for plants held in ethylene-free air. The involvement of endogenous ethylene in the postharvest deterioration of miniature roses was examd. by comparing the behavior, in air, of plants pre-treated with STS or with 1-methylcyclopropene, a gaseous inhibitor of ethylene action that has very low phytotoxicity. The inhibitors retarded bud and leaf abscission, but had no effect on leaf yellowing, and thus ethylene is not the primary agent of leaf yellowing in miniature roses. .

DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) Section cross-reference(s): 19 Cherry tomatoes harvested as bunches are susceptible to abscission during storage. Two abscission zones are present in the bunch: the joint (AJ) in the middle of the pedicel and the receptacle (AR), which connects the fruit to the pedicel. It is demonstrated in the present study that during the temperate winter, after storage at 12 °C abscission commences through the AJ and that during the spring there is a transition to AR. Fruit harvested in the summer mostly underwent the AR type. It has been shown that 1-methylcyclopropene (1-MCP) can prevent abscission in cv. R-819. It is now shown that in early winter lower doses of 1-MCP are required to suppress abscission than during the warmer season. Of three cultivars tested, cvs. Shiren and Conchita had less abscission after storage than R-819, and 1-MCP could suppress abscission in all of them to various extents. Exposure of cv. Shiren to 50 ml l-1 of ethylene for 3 h did not induce abscission whereas 1-MCP reduced both AJ and AR abscission, and delayed ripening, as indicated by fruit color and firmness. Delay of red color development required lower doses of 1-MCP than inhibition of abscission. The variability in abscission of bunch tomatoes during the season indicates that multiple environmental signals det. the final quality of the produce. .
