Resistance to injury by sulfur dioxide : correlation with its reduction to, and emission of, hydrogen sulfide in Cucurbitaceae.
In Cucurbitaceae young leaves are resistant to injury from acute exposure to SO(2), whereas mature leaves are sensitive. After exposure of cucumber (Cucumis sativus L.) plants to SO(2) at injurious concentrations, illuminated leaves emit volatile sulfur, which is solely H(2)S. Young leaves emit H(2)S many times more rapidly than do mature leaves. Young leaves convert approximately 10% of absorb...

متن کاملMechanisms of resistance to sulfur dioxide in the Cucurbitaceae.
The relative resistance of four cultivars of the Cucurbitaceae (Cucumis sativus L. cv. National Pickling, and inbred line SC 25; Cucurbita pepo L. cv. Prolific Straightneck Squash, and cv. Small Sugar Pumpkin) to SO(2) was determined. According to plots of the degree of exposure to SO(2) (which depends on the SO(2) concentration and the duration of the exposure), there is an 8-fold difference i...
متن کاملSulfur Dioxide
The ubiquity of sulfur dioxide as an air pollutant combined with reports of effects of the gas and its blood metabolite on DNA and chromosomes, prompted a study of possible mutagen action on mammalian oocytes. Utilizing in vitro and in vivo systems, mouse, ewe, and cow oocytes were examined for cytologic evidence of structural or numerical damage in meiosis. Fragmentation with rearrangement see...
متن کاملPnm-18: Maternal Exposure to Ozone, Nirogen Dioxide, Sulfur Dioxide and Spontaneous Abortion
Background: Adverse pregnancy outcomes (low birth weight, prematurity and intrauterine growth retardation) are associated with exposure to urban air pollution. Experimental data have also shown that such exposure elicits adverse reproductive outcomes. We examined association between spontaneous abortion of the first trimester of pregnancy and ambient concentrations of Ozone, Nirogen Dioxide and...
