“…Ethylene is produced by plants during normal growth and development and is usually released into the atmosphere without accumulating (Pierik et al 2006). Martin and Sinnaeve (1987) grew wheat in a sealed soil‐plant atmosphere system [Experimental Soil Plants Atmosphere System (ESPAS) chambers, Wageningen, the Netherlands]. They reported that the ethylene concentration during the first 11 days accumulated to 100–200 nmol mol −1 , which was sufficient to affect plant growth.…”

Elevated levels of ethylene occur in controlled environment agriculture and in spaceflight environments, leading to adverse plant growth and sterility. The objectives of this research were to characterize the influence of ethylene on carbon dioxide (CO(2)) assimilation (C(A)), dark period respiration (DPR) and growth of lettuce (Lactuca sativa L. cv. Buttercrunch) under ambient and low total pressure conditions. Lettuce plants were grown under variable total gas pressures of 25 kPa (hypobaric) and 101 kPa (ambient) pressure. Endogenously produced ethylene accumulated and reduced C(A), DPR and plant growth of ambient and hypobaric plants. There was a negative linear correlation between increasing ethylene concentrations [from 0 to around 1000 nmol mol(-1) (ppb)] on C(A), DPR and growth of ambient and hypobaric plants. Declines in C(A) and DPR occurred with both exogenous and endogenous ethylene treatments. C(A) was more sensitive to increasing ethylene concentration than DPR. There was a direct, negative effect of increasing ethylene concentration reducing gas exchange as well as an indirect ethylene effect on leaf epinasty, which reduced light capture and C(A). While the C(A) was comparable, there was a lower DPR in hypobaric than ambient pressure plants - independent of ethylene and under non-limiting CO(2) levels (100 Pa pCO(2), nearly three-fold that in normal air). This research shows that lettuce can be grown under hypobaria ( congruent with25% of normal earth ambient total pressure); however, hypobaria caused no significant reduction of endogenous ethylene production.

“…Elevated levels of ethylene have been reported in enclosed environments (Abeles et al 1992) and implicated in microgravity -spaceflight experiments (Wheeler et al 1996). Martin and Sinnaeve (1987) reported that wheat grew poorly in an ambient (101 kPa) chamber with ethylene at 100 -200 nmol mol -1 (ppb). When the ethylene was removed by an activated alumina column, the plants grew normally.…”

“…In addition, experiments on growing wheat to maturity in space initially failed to produce viable seed, and this was later attributed to the high (≈1 to 2 ppm) ethylene levels in Mir Space Station atmosphere (Bingham et al, 2000;Salisbury, 1997). Subsequent tests in which cabin ethylene levels were reduced resulted in successful seed production by the wheat plants (Bingham et al, 2000;Salisbury, 1997) Preliminary tests in our large chamber showed that potassium permanganate fi lters were effective for controlling ethylene (Martin and Sinnaeve, 1987). Tests with catalytic burners, UV degradation, selective membranes, different sorbents, or even ethylene metabolizing microbes also have been considered for ethylene control (Abeles et al, 1992;Eastwell et al, 1978).…”

Ethylene production by 10 or 20 m2 stands of wheat, soybean, lettuce, potato, and tomato was monitored throughout growth and development in an atmospherically closed plant chamber. Chamber ethylene levels varied among species and rose during periods of canopy expansion and rapid growth for all species. Following this, ethylene levels either declined during seed fill and maturation for wheat and soybean, or remained relatively constant for potato and tomato (during flowering and early fruit development). Lettuce plants were harvested during rapid growth and peak ethylene production. Chamber ethylene levels increased rapidly during tomato ripening, reaching concentrations about 10 times that measured during vegetative growth. The highest ethylene production rates during vegetative growth ranged from 1.6 to 2.5 nmol·m-2·d-1 during rapid growth of lettuce and wheat stands, or about 0.3 to 0.5 nmol·g-1 fresh weight per hour. Estimates of stand ethylene production during tomato ripening showed that rates reached 43 nmol·m-2·d-1 in one study and 93 nmol·m-2·d-1 in a second study with higher lighting, or about 50× that of the rate during vegetative growth of tomato. In a related test with potato, the photoperiod was extended from 12 to 24 hours (continuous light) at 58 days after planting (to increase tuber yield), but this change in the environment caused a sharp increase in ethylene production from the basal rate of 0.4 to 6.2 nmol·m-2·d-1. Following this, the photoperiod was changed back to 12 h at 61 days and ethylene levels decreased. The results suggest three separate categories of ethylene production were observed with whole stands of plants: 1) production during rapid vegetative growth, 2) production during climacteric fruit ripening, and 3) production from environmental stress.
