“…Phytotoxicity rather than inhibition of ethylene action was indicated, since application of ethephon did not even partially alleviate the inhibitory effect of AgNOa. Similarly, application of TH6241, an inhibitor of the action of ethylene on cell permeability [19], at concentrations between 5 x lo-'M and 5 x 10T3 M, had no effect on germination in the light or with ethephon and GAG,, in the dark.…”

Abstract. The temperature-dependent primary dormancy of cv Florida 683 celery seeds in darkness was broken by GA,, (2 X lo-' M) alone but other growth regulators such as BA, ethephon or daminozide were necessary to break dormancy of cv Lathom Blanching seeds in the presence of GA,, at this concentration. Although AgNO, partially inhibited both the ethephon-and BA-induced germination of cv Lathom Blanching seeds in the presence of GA.,,, in the dark it did not affect the promotive action of daminozidc. Ethephon did not overcome the inhibitory action of high concentrations of AgNO, in thelight. The ethylene synthesis inhibitor aminoethoxyvinylglycine (AVG) did not inhibit the germination of cv Lathom Blanching seeds induced by growth regulators in the dark or in the absence of growth regulators in the light. Fusicoccin (FC) did not break celery seed dormancy unless applied in the presence of GA,, , . Germination of cv Lathom Blanching celery seeds treated with GA,,, at 16 "C in the dark was inhibited by the K+ ionophore benzo-18-crown-C-6 (18-C-6) and In the presence of Cal+ by the Ca*+ ionophore A23 187; the 18-C-6 inhibition was reversed by BA.It is concluded that the involvement of gibberellin in celery seed dormancy is not dependent on endogenous ethylene and is directly or indirectly controlled through the action of other hormones on transmembranc ion fluxes.

“…These suggestions are consistent with proposals made by Brown & Edwards (1945), that Striga lacks a germination factor which is synthesized during the pre-treatment period. The proposal that compartmentalized endogenous compound(s) are involved is further substantiated by reports that some of the Striga germination stimulants are known to affect permeability and transport across cellular membranes (Aboles, 1973;Parups, 1977). In this context it is of interest that the observed rate of germination on control discs was low (2-8%) when the latter were placed with discs treated with thidiazuron.…”

Summary: Résumé: Zusammenfassung Thidiazuron at 0.1 to 10 mg 1−1 induced concurrent germination and haustorium initiation in Striga asiatica (L.) Kuntze and S. hermonthica (Del.) Benth, but it had no effects on S. gesnerioides (Willd.) Vatke. Both millet and sorghum strains of S. hermonthica were equally responsive. The response of Striga seeds to thidiazuron increased with conditioning. Early applications of the compound induced some germination, but had adverse effects on the conditioning process. Induction de la germination des graines de Striga par le thidiazuron Le thidiazuron de 0,1 à 10 mg 1−1 a induit de façon conjointe le germination et l'initiation d'haustoria chez Striga asiatica et S. hermonthica, mais n'a pas eu d'effet sur S. gesnerioïdes. Les souches de S. hermonthica liées au millet et au sorgho ont un comportement équivalent. La réponse des graines de Striga au thidiazuron a augmenté par conditionnement préalable. Des applications précoces de produit ont induit quelques germinations, mais ont eu des effets contraires sur Ie processus de conditionnement. Einleitung der Samenkeimung bei Striga‐Arten durch Thidiazuron Mittels Thidiazuron‐Lösungen von 0,1 bis 10 mg 1−1 konnten eine gleichzeitige Keimung und Ausbildung der Haustorien bei Striga asiatica (L.) Kuntze und S. hermonthica (Del.) Benth. herbeigeführt werden, nicht jedoch bei S. gesnerioides (Willd.) Vatke. Der Rispenhirsen‐und der Sorghum‐Typ von S. hermonthica reagierten in gleichem Maße. Konditionierung der Striga‐Samen förderte die Wirkung von Thidiazuron. Frühe Anwendung des Wirkstoffs führte zu einer geringen Keimung, beeinträchtigte jedoch die Konditionierung.

“…The weight loss caused by ethylene in experiment 1 could totally be prevented by pre‐treatment with 1‐MCP, and the weight loss in experiment 2 was inhibited by pre‐treatment with 1‐MCP. Therefore weight loss by ethylene must have been mediated via the ethylene receptor and might be due to an effect on cell membrane permeability (Parups 1977). Ethylene and CO 2 not only acted additively but CO 2 could even enhance the effect of ethylene: at 0 kPa CO 2 there was no effect of 0.003 Pa ethylene whereas at 10 kPa CO 2 there was a large effect of 0.003 Pa ethylene.…”

The effect of CO2 on ethylene-induced gummosis (secretion of polysaccharides), weight loss and respiration in tulip bulbs (Tulipa gesneriana L.) was investigated. A pretreatment with 1-MCP prevented these ethylene-induced effects, indicating that ethylene action must have been directed via the ethylene receptor. Treatment with 0.3 Pa ethylene for 2 days caused gummosis on 50% of the total number of bulbs of cultivar Apeldoorn, known to be sensitive for gummosis. Addition of CO2 (10 kPa) reduced the ethylene-induced gummosis to 18%. In a second experiment the influence of ethylene and CO2 on respiration and FW loss of bulbs of the cultivar Leen van der Mark was studied. A range of ethylene partial pressures (0.003-0.3 Pa) was applied continuously for 29 days. Ethylene caused a transient peak in O2 consumption rate during the first days after the start of application. The relation between O2 consumption rate and ethylene partial pressure could be described by Michaelis-Menten kinetics. Respiratory peaks were reduced by CO2. This inhibition by CO2 could not totally be due to competition with ethylene at the receptor binding-site, as was indicated by the use of an O2 consumption model. Pre-treatment of bulbs with 1-MCP and subsequent exposure to CO2 showed that CO2 could influence respiration irrespective of any interaction with ethylene. Ethylene and CO2 both stimulated weight loss. The effect of combined treatments of ethylene and CO2 on weight loss was at least as strong as the sum of the separate effects, which implies that competition between ethylene and CO2 at the receptor binding-site was unlikely.
