Effects of Ethylene

The effect of GA on root elongation shows some light dependence. Bur-STROM (1960) reported that GA reverses the inhibition of wheat root elongation by light while, in the dark, GA acts to inhibit root elongation, apparently by shortening the cell elongation phase of development. [Pg.53]

Ethylene rapidly inhibits root elongation (Andreae et al. 1968, Radin and Loomis 1969, Chadwick and Burg 1970, Rauser and Horton 1975, McBride and Evans 1977) and there is evidence that both roots (Radin and Loomis [Pg.53]

Chadwick and Burg 1970, McBride and Evans 1977) and soil microorganism in the vicinity of roots (Ilag and Curtis 1968, Archer 1976) produce ethylene. It therefore seems likely that ethylene plays a role in the control of root elongation. [Pg.53]

Subsequent mechanistic studies suggested that the abovementioned effect of ethylene on reaction efficiency is connected to a mechanistic divergence that exists for reactions of terminal styrenyl ethers versus those of disubstituted styrene systems [13b]. Whereas with monosubstituted styrenyl substrates the initial site of reaction is the terminal alkene, with disubstituted styrene systems the cyclic ji-systems react first. This mechanistic scenario suggests two critical roles for ethylene in the catalytic reactions of disubstituted styrenes ... [Pg.127]

Hansen18 suggested that inasmuch as such quicker ripening is closely associated with the more rapid transformation of the insoluble pectic constituents into soluble ones, the effect might be, partly at least, the result of an activation of protopectinase by the ethylene. The activating effect of ethylene on isolated protopectinase (or on PG) has never been demonstrated. [Pg.98]

A retrospective assessment of the potential antifertility influence of ethylene dibromide was conducted by studying the reproductive perfonnance of men exposed to ethylene dibromide in the workplace. Data were obtained from four chemical plants manufacturing ethylene dibromide located in the southern part of the United States (Arkansas and Texas). Exposures in the plants ranged from less than 0.5 ppm to 5 ppm [3.8-38 mg/m- ]. Evaluations were made exclusively on the basis of the men s reproductive histories of live births to their wives, subsequent to their occupational exposure. The mmiber of live births was compared with the expected mmiber derived from national fertility tables. One of the four plants studied showed a significant decrease in fertility however, when data from the four plants were combined, there was no significant effect of ethylene dibroniide exposure on reproductive performance (Wong et al., 1979). [Pg.650]
