“…It has been reported that ethephon has a role in inhibiting plant growth5, promoting stomatal opening6 and flowering78, inducing pollen sterility9, influencing biosynthesis of secondary metabolites101112 and fruit ripening, improving fruit quality1314151617, enhancing herbicide efficacy pretreatment18, eradicating pests19, depressing vesicular arbuscular mycorrhiza formation20 and nodulation21, and facilitating the harvest of fruits2223. Some research also indicates that high concentrations of ethephon are phytotoxic and can cause damage to plants2425.…”

Several auxin herbicides, such as 2, 4-D and dicamba, have been used to eradicate an exotic invasive weed Ipomoea cairica in subtropical China, but restraining the re-explosion of this weed is still a challenge. Since ethylene is one of the major intermediate functioning products during the eradication process, we explored the possibility, mechanism and efficiency of using ethephon which can release ethylene to control Ipomoea cairica. The results of the pot experiment showed that 7.2 g /L ethephon could totally kill Ipomoea cairica including the stems and roots. The water culture experiment indicated that ethephon released an abundance of ethylene directly in leaves and caused increases in electrolyte leakage, 1-aminocyclopropane-1-carboxylic acid (ACC), abscisic acid (ABA) and H2O2 and decreases in chlorophyll content and photosynthetic activity, finally leading to the death of Ipomoea cairica. The field experiment showed that the theoretical effective concentration of ethephon for controlling Ipomoea cairica (weed control efficacy, WCE = 98%) was 4.06 g/L and the half inhibitory concentration (I50) was 0.56 g/L. More than 50% of the accompanying species were insensitive to the phytotoxicity of ethephon. Therefore, ethephon is an excellent alternative herbicide for controlling Ipomoea cairica.

“…Under in vitro conditions, ethylene enhanced the regeneration efficiency, increased the shoots number and height, improved rooting and stimulated the tracheary element differentiation (Prameswara et al, 2009;Pesquet & Tuominem, 2011;Yasmin et al, 2014 (Gabriele et al, 2010;Ikezaki et al, 2010;Mauriat et al, 2011;Nadeau et al, 2011;Zhao et al, 2011;Taiz & Zeiger, 2013). Application of gibberellin to the culture media inhibited adventitious root formation (Niu et al, 2013), but promoted shoot development and multiplication in Lotus corniculatus (Nikolic et al, 2010) and…”

The use of plant growth regulators is directly related to the success of in vitro propagation, which is an advantageous alternative to obtain seedlings on a commercial scale. This study aimed to evaluate the in vitro development of ‘IAC 95-5000’ sugarcane seedlings after the addition of different doses of ethephon (0, 25, 50, 100 and 200 mg L-1) or gibberellic acid (0, 2.5, 5.0, 7.5 and 10.0 mg L-1) to the culture medium. Ethephon increased the number of tillers (up to 231.70%), reduced height of the main tiller (44.66 to 60.47%), and did not affect the shoot´s fresh and dry mass. On the other hand, gibberellin decreased the number of tillers and negatively changed biomass partitioning. It is concluded that the use of ethephon is a potential strategy to enhance in vitro production of ‘IAC 95-5000’ sugarcane seedlings, since it increased the number of usable shoots in subsequent subcultures, and its effects on height reduction can be reversible. However, the use of the tested doses of gibberellic acid is not recommended, because it impaired seedling development of this sugarcane variety.
