Abstract
Sulphur dioxid, hydrogen sulphate, nitrous gases, and ammonia as sole source of S and N for higher plantsLong duration gasing experiments using SO2, H2S, nitrous gases and NH3, showed, that higher plants can use these gases as only source of S or N respectively, without affecting their normal growth during the whole vegetation period.The sulphur and nitrogen of these high oxidized or high reduced gas forms were taken up by the plants and were also translocated to the roots.The assimilation of sulphur, given as SO2, was more intensive than that given as H2S. The uptake of nitrogen, given as ammonia, was higher than that given as nitrous gases.
