  1. Ann. Tabac, 1983-84, Sect. 2-17, p. 131-9., ISSN.0399-0354

    Diterpenes in Nicotiana tabacum. II. A technique for the breeding of tobaccos as a function of their production of alpha and beta-cembratriene-diols

    COUSSIRAT J.C.; SCHILTZ P.; BOUTERAOU Y.
    The cembratriene-diols were synthetized by Nicotiana tabacum with the emergence of primary leaves. By contrast, (Z)-abienol appeared only 55 days after germination. Of the two major diterpenes on N. tabacum leaf surface, (Z)-abienol and alpha and beta ...

    A biochemical study of tobacco subjected to"Cotyledon-test"conditions : effect of magnesium reactions of plants resistant and susceptible to Peronospora tabacina. I. Soluble protein content in non-contaminated tobaccos

    EDREVA A.; MOLLE E.; SCHILTZ P.
    Young tobacco plants supplied with Mg2+ solution at the cotyledon stage have a higher soluble protein content than that induced by a more complete nutrient (Knop 1/2). However, no difference between varieties resistant and non-resistant to Peronospora ...

    A biochemical study of tobacco subjected to"Cotyledon-test"conditions : effect of magnesium, reactions of plants resistant and susceptible to Peronospora tabacina. II. Peroxidase activity in non-contaminated tobaccos

    EDREVA A.; MOLLE E.; SCHILTZ P.
    Ten day-old tobacco plants supplied with Mg2+ solution have a more intense peroxidase activity than those supplied with Knop 1/2 nutrient. Under these conditions (Mg2+) the varieties resistant to Peronospora tabacina A. produce more peroxidases than non ...
  4. Ann. Tabac, 1983-84, Sect. 2-17, p. 171-5., ISSN.0399-0354

    A biochemical study of tobacco subjected to"Cotyledon test"conditions : effect of magnesium, reactions of plants resistant and susceptible to Peronospora tabacina. III. Chemiluminescence induced in tobaccos contaminated or not by blue mold

    MOLLE E.; EDREVA A.; BATSCHEV S.
    In young tobacco plants at the cotyledon stage, induced chemiluminescence (CHL), which is an indicator of the bio-physical condition of the membranes, depends on nutrition, the age of the plant and the degree of contamination by Peronospora tabacina A. If ...
