    Notes: [Auszug] Eight-year-old Eucalyptus camaldulensis trees at Pali, Rajasthan, were investigated. The lower (older) leaves of these trees yellowed from the tip backwards along the leaf edges and this was followed in some cases by browning of the leaf edges. Close examination of the affected leaves did not ...

    Description / Table of Contents: Summary In the context of investigations of the metabolism of insecticidal chlorinated hydrocarbons by means of14C-labelled compounds this report deals with the degradation of endrin, heptachlor and telodrin in warm-blooded animals, plants and micro-organisms. The resulting metabolites were identified partly as hydroxyl derivatives of the insecticides. After oral application of radioactively labelled endrin in rats — endrin shows the highest toxicity among all insecticides towards warm-blooded animals — the radioactivity was very quickly eliminated (accumulation after 13 days' application was 14% of the total activity; 5,3% remained three days after the last dose of endrin). The waste products, appearing mainly in the faeces, were found to be, beside small quantities of endrin, two hydrophilic metabolites. 20 days after plants(Brassica oleracea) were sprayed with endrin-14C the roots contained considerable amounts of a hydrophilous metabolite. The latter was also found in stems, leaves and in the soil.
    Abstract: Resumé Dans le cadre de recherches sur le métabolisme des insecticides à base d'hydrocarbures chlorés, effectuées à l'aide de composés marqués à14C, on expose les modalités de dégradation de l'endrine, de l'heptachlore et de la télodrine chez les animaux à sang chaud, chez les plantes et les micro-organismes; on a identifié une partie des métabolites obtenus comme dérivés hydroxyles des insecticides. Après l'administration par voie buccale à des rats d'endrine marquée, qui a, de tous ces insecticides, la plus grande toxicité pour les animaux à sang chaud, la radioactivité était très vite éliminée. L'activité résiduelle totale était de 14% après qu'on leur avait administré une dose quotidienne d'endrine pendant 13 jours et de 5,3% trois jours après la dernière administration. Parmi les produits éliminés, surtout dans les fèces, il faut citer, à côté de quantités réduites d'endrine, deux métabolites hydrophiles. 20 jours après la pulvérisation des plantes(Brassica oleracea L) avec de l'endrine-14C, les racines contenaient des quantités appréciables d'un métabolite hydrophile, que l'on a aussi détecté dans les tiges, les feuilles et le sol.
    Notes: Zusammenfassung Im Rahmen der Untersuchungen über den Metabolismus insektizider Chlorkohlenwasserstoffe mit Hilfe14C-markierter Verbindungen wird über den Abbau von Endrin, Heptachlor und Telodrin in Warmblütern, Pflanzen und Mikroorganismen berichtet; die entstandenen Metaboliten wurden zum Teil als Hydroxyl-Derivate der Insektizide identifiziert. Nach oraler Applikation von radioaktiv markiertem Endrin an Ratten — Endrin weist von allen diesen Insektiziden gegenüber Warmblütern die höchste Toxizität auf — wird die Radioaktivität sehr schnell ausgeschieden (Speicherung nach 13 Tagen, bei täglicher Applikation, 14% der Gesamtaktivität; drei Tage nach letzter Endrindosis 5,3%). Als Ausscheidungsprodukte treten, hauptsächlich in den Faeces, neben geringen Mengen Endrin zwei hydrophile Metaboliten auf. 20 Tage nach Besprühen von Pflanzen (Brassica oleracea) mit Endrin-14C enthalten die Wurzeln größere Mengen eines hydrophilen Metaboliten, der auch in Stengeln, Blättern und im Erdreich nachgewiesen wurde.

    Notes: Summary The results of adaptability trials carried out on 43 species ofEucalyptus in two different environments viz., Jodhpur and Pali are discussed. It was observed that the species with wide latitudinal distribution and belonging to summer rainfall regions in their native habitat have done well compared to the species with narrow latitudinal distribution and belonging to winter rainfall areas. In general,Eucalyptus melanaphloia, E. terminalis andE. camaldulensis proved to be the most promising species and are recommended for large-scale species elimination trials in the region. However, for the region like Pali having calcareous soils,E. tessellaris should be preferred over other species as it has shown the best performance. The differential growth and development exhibited by different species in the two habitats suggest a need for studying the correct mycorrhizal fungus in the establishment and growth of the species.
