“…Continuous exposure to ethylene suppresses sprouting but can also prematurely terminate dormancy resulting in enhanced sprout growth once the gas is removed (Rylski et al 1974). In addition, the onset of sprout growth following natural dormancy break is accompanied by increased ethylene production (Creech et al 1973). The onset of sprouting following treatment with the synthetic cytokinins CP or NG is accompanied by significant increases in ethylene production that, in the case of NG, is sustained over the 14 day experimental period (Fig.…”

Minitubers often exhibit a more protracted dormant period relative to their field-grown counterparts and this can have a detrimental impact on plant establishment. Treatment of dormant Russet Burbank minitubers with the synthetic cytokinins N-(2-chloro-4-pyridyl)-N′-phenylurea (CP) or 1-(α-ethylbenzyl)-3-nitroguanidine (NG) resulted in the premature termination of tuber dormancy. In contrast, treatment with the thidiazoyl-urea cytokinin TZ did not stimulate sprouting. Both CP and NG were more effective than the naturally occurring cytokinin zeatin and, unlike zeatin, both stimulated sprouting in minitubers during early storage. Unlike treatment with gibberellic acid (GA) which often induced excessive sprout growth, sprouts developing from minitubers treated with either cytokinin were short, thick, and robust. Upon transfer to room temperature, the endogenous content of ABA in apical bud periderm discs isolated from control minitubers declined more than 60% over a 15 day period. Treatment with either CP or NG had no appreciable effect on this decline while treatment with GA diminished the decrease in ABA content. Treatment with either synthetic cytokinin resulted in a large and sustained increase in endogenous ethylene production that was detectable immediately prior to visible sprout growth. In contrast, GA treatment resulted in a much smaller increase that was observed after sprout growth commenced. These results indicate that either CP or NG treatment can be effectively used to prematurely terminate tuber dormancy and induce sprout growth.Resumen Los mini tubérculos exhiben a menudo un prolongado periodo de latencia con relación a sus contrapartes que han crecido en el campo y esto puede tener un impacto perjudicial en el establecimiento de la planta. El tratamiento de los mini tubérculos latentes de Russet Burbak con citoquininas sintéticas N-(2-cloro-4-piridil)-N′-fenilurea (CP) o 1-(α-etilbenzil)-3-nitroguanidina (NG) dieron como resultado el final prematuro de la latencia. Contrariamente, el tratamiento con tidiazoil-urea citoquinina TZ, no estimuló el brotamiento. La CP y el NG fueron más efectivos que la citoquinina zeatina que se presenta en forma natural y a diferencia de la zeatina, ambos estimularon el brotamiento de los mini tubérculos durante el inicio del almacenaje. A diferencia del tratamiento con ácido giberélico (GA), el cual a menudo induce excesivo crecimiento del brote, los brotes que se desarrollan a partir de los mini tubérculos tratados con cualquier citoquinina fueron cortos, gruesos y robustos. Después de la transferencia a la temperatura ambiente, el contenido endógeno ABA, en los discos del peridermo del brote apical aislado de mini tubérculos testigo, disminuyo más del 60% en un periodo de 15 días. El tratamiento sea con CP o NG no tuvo efecto apreciable sobre esta disminución mientras que el tratamiento con GA disminuyó la reducción del contenido de ABA. El tratamiento con cualquiera de las dos citoquininas sintéticas dio como resultado un sostenido incremento de la producción de et...

“…The response varies among cultivars (Haard, 1971; Prange and Daniels-Lake, unpublished data) and darkening is concentration-dependent below about 4 µL•L -1 (Daniels- . Ethylene is a metabolic product of potato tubers (Poapst et al, 1968;Suttle 2003) and the rate of production increases in response to stress (Creech et al, 1973;Korableva and Ladyzhenskaya, 1995;McGlasson, 1969;Poapst et al, 1968). Numerous potato storage pathogens also produce ethylene (summarized in Arshad and Frankenberger, 2002b).…”

For many years, the accepted wisdom among potato storage researchers and industry personnel linked the accumulation of CO2 in the storage atmosphere to darkening of potato fry color. Dark fry color is undesirable in the potato processing industry, as consumers prefer light-colored finished products. Previous research to elucidate the effect of CO2 has presented conflicting results. In three consecutive years of storage trials, the effects of elevated CO2 concentrations, reduced O2 concentrations and ethylene gas on the fry color and sugar content of `Russet Burbank' potato (Solanum tuberosum L.) tubers were evaluated. The potatoes were stored in modified atmosphere chambers and selected atmosphere mixtures were supplied from compressed gas cylinders. Four 3-week trials were conducted in 2002 and two 9-week trials were conducted in each of 2003 and 2004. Fry color and tuber sugars were assessed at the start of each trial and after several weeks of exposure to the treatment atmospheres. Compared with untreated controls, increased CO2 alone or in combination with decreased O2 had little or no effect on fry color or tuber sugars. During the second and third years, only selected treatments were repeated, with or without the addition of 0.5 μL·L–1 ethylene gas. Ethylene is known to affect potato fry color and reducing sugars. In three of four trials, tubers exposed to ethylene alone had darker fry color and higher reducing sugars compared with controls. Applied treatments had little or no effect on fry color and sugars in the fourth trial. Interestingly, in the same three of four trials, fry color of tubers exposed to both elevated CO2 and ethylene gas was not only darker than controls but also darker than tubers treated with ethylene alone. Similarly, reducing sugar concentrations were higher in tubers exposed to both ethylene and CO2 than with ethylene alone. No similar interaction between ethylene and oxygen concentration was observed. The results suggest a synergistic negative effect of trace ethylene and elevated CO2 on fry color, which may explain the apparently contradictory findings of some published research examining the effects of CO2 on potato fry color.

“…Specific rates and levels are available in the literature with many of them compiled in Agriculture Handbook number 66 (Gross, Wang, & Saltveit, 2016). Exposure to a low O 2 concentration inhibits ethylene action and production (Gorny & Kader, 1997), while concentrations of O 2 greater than 21% (air) have been reported to alter ethylene production in a way that enhances ethylene‐induced physiological disorders in a variety of crops (Creech, Workman, & Harrison, 1973). The inhibition of ethylene production under low O 2 levels is partly because O 2 participates in the oxidation of ACC to ethylene (Dilley et al., 2013).…”

Produce is rapidly gaining market share worldwide. Ethylene is a gas molecule that causes detrimental changes in produce. Thus, it is crucial to reduce surrounding ethylene besides inhibiting ethylene biosynthesis to extend produce shelf life and reduce food waste. Ethylene-removing packaging (ERP) can reduce ethylene concentration surrounding produce during transportation and commercialization. The information found in the literature on the topic is minimal and incomplete compared to other types of active packaging. It focuses on compounds with an ethylene-removing capacity rather than on the packaging technology per se. The goal of this literature review is to compile and discuss information from peer-reviewed scientific papers and industry websites on the basics on ERP and on recent developments that can be used to build on and to advance this type of active packaging. This review first focuses on factors needed to design effective ERP including produce characteristics, in-package composition, material properties and their changes after compounding, remover properties, integration techniques, and environment. Next, this review presents a classification for ERP and provides a detailed analysis of various ethylene-removing compounds including their mechanisms of action, integration techniques, impacts on produce shelf life, advantages and drawbacks including safety, commercial applications, and combinations with other shelf-life extending technologies. Some ERP designs are more promising to extend produce shelf life than others, but there is still room for further research to advance this packaging strategy. Specific needs include investigation of ethylene removal for fresh-cut produce and exploring different integration techniques and materials for such integration.
