A review of ethylene effects in bulbous plants

Gum Formation by Methyl Jasmonate in Tulip Shoots is Stimulated by Ethylene

“…Applying high concentrations of IAA or naphthaleneacetic acid (NAA), which induced ethylene, did not induce gum formation in the stem of tulip (Saniewski et al, 1990). These results suggest that JA-Me, but not ethylene, is essential for gum formation in tulip shoots, although the process of gummosis is considered to be regulated by ethylene in tulip bulbs (De Hertogh et al 1980, De Munk and Saniewski 1989, Kamerbeek and De Munk 1976, Kamerbeek et al 1971, Moe and Hagness 1975. In tulip bulbs, ethylene induced gum (Saniewski and Puchalski 1988), as well as JA-Me.…”

“…In tulip bulbs, infection by Fusarium oxysporum f. sp. tulipae and the application of ethylene or the ethylene-generating compound ethephon has been found to induce gum formation (De Hertogh et al, 1980, De Munk and Saniewski 1989, Kamerbeek and De Munk 1976, Kamerbeek et al, 1971, Moe and Hagness 1975. JA-Me has also been reported to stimulate ethylene production in various plants such as preclimacteric apples (Saniewski et al 1986); tomatoes (Saniewski andCzapski 1985, Saniewski et al 1987); rice leaves (Chuo and Kao 1992); olive leaves (Sanz et al 1993); flowers of Dendrobium, Petunia, and Phalaenopsis (Porat et al, 1993(Porat et al, , 1995; and tendrils of Bryonia dioica (Weiler et al 1993).…”

Different ethylene production in vitro by several species and formae speciales of Fusarium

“…It may be concluded that all species and formae speciales of Fusarium produce ethylene but that only Fusarium oxysporum f. tulipae produces very high quantities (up to 5000 times more), although differences were found between the various isolates. The high ethylene production of the tulip Fusarium, also found in vivo (de Munk, 1972) must be taken into account in the investigation of host-parasite interactions, because ethylene can influence many processes in tulips (Kamerbeek and de Munk, 1976). The finding that the synthesis of tuliposid, regarded as a barrier against infection by Fusarium in the scale tissue of tulips, is suppressed by ethylene, is of interest in further studies of the host-parasite relation (Beijersbergen and Bergman, 1973).…”

“…Studies on the cause of some physiological disorders in tulips have shown that ethylene produced by Fusarium oxysporum f. tulipae is a factor in the genesis of bud necrosis, flower-bud blasting, gummosis, root and shoot inhibition, and other aberrations seen in tulips (Kamerbeek and de Munk, 1976). This led us to investigate factors influencing in vitro ethylene production by the tulip Fusarium (Swart and Kamerbeek, in preparation).…”

Neoseiulus paspalivorus, a predator from coconut, as a candidate for controlling dry bulb mites infesting stored tulip bulbs

“…In fact, in practice ethylene is continuously diluted and led away from the storage rooms by ventilation, because of its adverse effects on flower development (de Munk 1973, Kamerbeek and de Munk 1976, Gude and Dijkema 2005 and increased risks of bud necrosis (Lommen et al 2012b). Hence, there is a need to find predators that do not only feed on the dry bulb mite, but are also small enough to enter the inside of the bulb under storage conditions in practice.…”
