“…External sources of C2H4, such as from auto exhaust, may induce the same effects as endogenous C2H4, including inhibition of stem elongation and leaf expansion, promotion of senescence and abscission, induction of epinasty, and a reduction of flowering and fruit set. A reduction of flowering and fruitset was found in petunia, cucumber, soybean, kidney bean, and wheat when exposed to 25 ppb of C2H4 (Abeles and Heggestad 1973). Epinasty in tomato was proposed as a useful biomonitoring symptom for atmospheric C2H4 (Abeles and Heggestad 1973).…”

“…As a constituent of air, ethylene can also be a phytotoxic pollutant (Squier et al, 1985) with serious consequences primarily in confined areas such as those used for fruit storage. As an indirect or secondary phytotoxicant produced in response to stress agents such as SO 2 and O 3 , ethylene plays a significant role in the response of plants to air pollutants (Abeles and Heggestad, 1973;Abeles, 1982). In the field, ethylene from anthropogenic sources is thought to be less effective than stressinduced endogenous ethylene because the concentrations are low and exposure episodes tend to be transient.…”

Ethephon, which releases ethylene within plant tissues after application, was chosen to perform assessments of the relative sensitivity of crops to ethylene and to determine which stages of plant development were most sensitive. The species chosen were: barley, wheat, oats, canola and field pea, all of which are important crops in the province of Alberta, Canada. Plants were treated with ethephon at one of 7 different stages. Plants were assessed for their vegetative and reproductive growth, including height, biomass, yield and seed quality. Visual symptoms were photographed and documented to compare them with symptoms caused by ethylene applied as a gas. It was concluded that in barley, wheat and canola the late vegetative and early reproductive stages were most sensitive, at least when sensitivity was defined as reductions in yield and quality. As for field pea, ethephon had no effect on yield but did cause increased numbers of pods, which in certain conditions could lead to increased yields. Significant effects on vegetative growth were only observed in the early vegetative stages of development but with no effects on yield. The screening protocol successfully identified sensitive cultivars and growth stages for further investigation of the effects of ethylene exposure.

“…As a result of reaction with the OH-radical, ethylene plays an essential role in chemistry of the troposphere [5]. Ethylene is also one of the important objects studied in astrophysics and planetology: it has been detected in significant amounts in the atmospheres of Jupiter, Saturn, Neptune, and Titanium Satellites [6][7][8][9][10][11].…”

Analysis of the High-Resolution Fourier Spectrum of the ν6 Band of the cis-C2h2d2 Molecule

The spectrum of the ν 6 band of the cis-ethylene-d 2 molecule (cis-C 2 H 2 D 2 ) is recorded with a Bruker IFS 125 HR Fourier spectrometer in the range 580-1210 cm -1 with resolution of 0.0021 cm -1 . An analysis of the experimental spectrum allows more than 1500 transitions belonging to this band to be assigned that by more than 2.5 times greater than it has been known in the literature so far. The obtained experimental data are then used to determine the model parameters of the molecule (the effective Hamiltonian in the A-reduction and I-representation). Strong resonance interaction with the band ν 4 forbidden in absorption by the symmetry of a molecule is taken into account. 10 parameters of the Hamiltonian obtained by solving inverse spectroscopic problem reproduce 427 initial experimental energies (more than 1500 transitions) with accuracy close to the experimental uncertainty.
