    COLORIMETRIC ESTIMATION OF TOTAL ALDEHYDES IN AQUEOUS ORANGE ESSENCE USING N-HYDROXYBENZENESULFONAMIDE (1970)

    Notes: A spot test method for detection of aldehydes has been adapted calorimetrically for quantitative determination of total aldehydes in aqueous solutions. The final colored complex has an absorption maximum at 510-525 mμ. The technique is simple, and the color produced is linear with aldehvde concentrations up to 300 mg/liter using n-octanal and trans-2-hexenal as a mixed standard. The test is applicable to aldehyde determinations in orange essence provided proper sample dilution is made before analysis.

    Uptake, Distribution and Translocation of 32P Absorbed through Roots of Cotton Seedlings as Affected with CCC Treatment (1970)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 23 (1970), S. 0 
    Details
    ISSN: 1399-3054

    Topics: Biology
    Notes: The effects of CCC on the 32 P amounts absorbed by cotton seedlings were studied. CCC was applied to the seedlings either as spray or as addition to the nutrient solution in concentrations of 0, 25, 50, 100 and 200 mg/1. 32P was added to the medium as KH232P O4 in the concentration of 40 μCi/50 ml.During the experimental period, no morphological changes were observed. The total 32P uptake was inhibited in CCC treated seedlings. The application of CCC, both as spray and as addition to the medium, led to an accumulation of 32P in stem, but to a decrease in root. The leaves showed different responses to different methods of application; spraying increased, while an addition of CCC to the medium decerases the 32P content in the leaves. It is concluded that CCC inhibits 32P uptake, whereas it ac accelerates the 32P translocation from root to the aerial parts.
