“…A few data relating to hypocotyl segments are included. Where the latter were used, the material and methods were as described in our previous paper (6) In the case of efflux experiments the disks were next transferred to 30 ml experimental media. The latter contained osmoticum and substances to be tested, and were all adjusted to the same osmotic value.…”

“…Following our recent observation (6) that CO2 brought about a rapid change in rate of water movement into and out of plant cells, we wished to determine whether this effect was brought about via a change in 6 or in Lp, the coefficient of hydraulic permeability. The distinction is of considerable qualitative importance; whereas a drop in Lp indicates a decrease in permeability to water, a drop in 6 would imply an increase in permeability to solutes.…”

“…Our earlier investigations (3) have shown that exogenously applied CO2 and ethanol increase cell permeability and reduce survival of wheat seedlings at concentrations equivalent to or lower than those accumulating within the plant. Both ethanol and CO2 also were shown elsewhere (11,14) to alter cell permea- bility and damage cell membranes of other plant species after prolonged exposure. It is possible that endogenously produced ethanol and CO2 results in similar damage during flooding.…”

Cold-hardened winter wheat (Triticum aestivum L. cv. Fredrick) and winter barley (Hordeum vulgare L. cv. Dover) were exposed to total flooding at 2 C. Dover seedlngs were damaged more quickly than Fredrick, and after 3 weeks of flooding the survival of Dover was reduced to 10% and Fredrick to about 50%. Tissue moisture was slightly greater in Dover than Fredrick throughout the 4-week flooding period. Carbon dioxide and ethanol accumulated throughout the 4-week flooding period in both cultivars. Lactic acid increased rapidly during the 1st week of flooding, and remained relatively constant during the remainder of the flooding period. Oxygen consumption of seedling shoot tissue after exposure to flooding declined abruptly after only 1 day of flooding, but recovered somewhat during the subsequent 2 weeks. The effect of flooding was more pronounced on the ultrastructure of Dover than Fredrick. Although proliferation of endoplasmic reticulum was observed in the early stages of flooding in both cultivars, the occurrence of distinct parallel arrays and concentric whorls of membranes was prevalent in the flooded barley. Severe ultrastructural damage to a large proportion of apical cells in both cultivars was observed after 2 to 3 weeks of flooding.Exposure of plants to partial or total flooding results in major alterations in various physiological and metabolic processes (5,8,9,21,22). In flooding-intolerant species, normal respiration is blocked or severely inhibited resulting in enhanced rates of glycolysis, accumulation of one or more potentially toxic metabolites of anaerobic metabolism, and injury to the plant (5, 17). Respiratory processes of flooding-tolerant species are not as adversely affected by flooding (15, 16), and hence the accumulation of anaerobic metabolites and associated injury is generally less pronounced than in flooding-intolerant species (5, 8). Therefore, we concluded (8) lesser degree in some plant species. Ethylene was shown to increase sharply during flooding and was associated with injury in several plant species (12, 13). It also was observed that tolerance to anoxia in germinating seeds (7) and grasses (4) is greater when the metabolic rate is reduced at low temperature. Flooding of winter cereals frequently occurs during autumn and spring in northeastern United States and eastern Canada. Low temperature flooding is currently being investigated in this laboratory as one of the factors influencing the winter survival of cereals. This paper reports changes in survival, cellular ultrastructure, and metabolic properties of a winter wheat and a winter barley during low temperature flooding in controlled environment conditions. MATERIALS AND METHODSCold-acclimated seedlings of Fredrick winter wheat (Triticum aestivum L.) and Dover winter barley (Hordeum vulgare L.) were used in this investigation. Seedlings were grown in soil for 5 days at 20 C light, 15 C dark with a 16-h day at a light intensity of 525 ,uE m-2 S-1 (about 35,000 lux) and then were transferred to 2 C light, 0 C dark wit...

The effect of 0.5 ppm ozone for 0.5‐1 hr on plant cell membrane permeability was ascertained. Permeabilities to both water and solutes were estimated by measuring leaf disc weight changes and following tritiated water and 86Rb fluxes. Measurements were made immediately after ozone exposure and 24 hr after exposure. The reflection coefficient, σ, an index of solute permeability, decreased in ozone‐treated primary leaves of pinto bean (Phaseolus vulgaris). The latter indicates an increase in membrane solute permeability or internal solute leakage. Water and THO flux estimates both indicated a decrease in membrane permeability to water; both the hydraulic conductivity (Lp) and the water diffusional coefficient (LD) apparently decreased, an anomaly which is discussed. These data indicate that ozone has a direct effect on membrane function by altering permeability characteristics. We assume from these data that cell membranes are primary target sites for ozone injury.
