Chloride and sodium are the main ions contributing to soil salinity in many regions but chloride is an essential element necessary for plant growth and development. It also controls the growth of some pathogens in plants. In this experiment, the effect of the chloride ion in nutrient solution on yield and fruit quality of two strawberry cultivars: ‘Selva’ and ‘Camarosa’ grown in hydroponic cult...

I Lewin, J. C., Science, 112, 652 (1950). 2 In the experiments reported here, cultures were grown on minimal medium plus sodium acetate (0.2 gm per 100 ml). The minimal medium, described in Levine, R. P., and Ebersold, W. T., Zeit. Vererbungs., 89, 632 (1958), was altered by a fivefold increase in the concentration of Beijerinck's solution. 3 Arnon, D. I., Plant Physiol., 24, 1 (1949). 4The aut...

Carbon dioxide fixation is a polyphyletic trait that has evolved in widely separated prokaryotic branches. The three principal CO2-assimilation pathways are (i) the reductive pentose-phosphate cycle, i.e. the Calvin-Benson cycle; (ii) the reductive citric acid (or Arnon) cycle; and (iii) the net synthesis of acetyl-CoA from CO/CO2, or Wood pathway. Sequence analysis and the comparative biochemi...

TO THE EDITOR—I write on behalf of the Department of Health and Human Services to clarify some matters addressed in the editorial commentary [1] accompanying the recently published article by Barash and Arnon [2]. In the Notes section , the commentary states, " A committee representing various branches of the US government reviewed and approved submissions of the manuscripts " [1] authored by B...

Soybean (Glycine max [L.] Merr. var. Glabrous D62-7812) plants were grown in aerated Hoagland and Arnon mineral nutrient solution containing 0 or 2.6 mum S-ethyl dipropylthiocarbamate (EPTC) in a growth chamber. After 19 days exposure to EPTC, total leaf fresh weight was reduced 18% by 2.6 mum EPTC while total leaf fatty acid content was reduced 63%. Galactolipid content decreased while phospho...
