    Notes: When the rate of dry-matter production of a grass crop is determined only by the incoming light energy, it increases exponentially until a closed green surface is reached. Thereafter the production is linear for some time, but soon it decreases and finally drops to zero. This decrease is partly caused by an increase in the rate of respiration relative to photosynthesis. However, there are still unknown factors affecting the rate of production, especially in the second half of the season. When a sward receives an optimal supply of water and nutrients the organic plant constituents at a given growth stage remain fairly constant throughout the season. It would be advantageous, however, to harvest grass with a higher sugar and a lower protein content. This seems to give better rumen digestion and, besides, would improve the regrowth of the sward. Since plants with a high rate of dry-matter production usually have a fairly low reserve level, it is unlikely that selection could provide a strain with both a high reserve level and a high rate of production.

    Notes: Résumé. Divers auteurs proposent d'expliquer les propriétés herbicides du 2,4-D par les modifications qu'il provoque dans le métabolisme auxinique mais leurs hypothèses à ce sujet sont souvent divergentes.L'action du 2,4-D sur la croissance et sur le catabolisme de l'AIA a étéétudiée in vitro et in vivo chez Hordeum hexastichum et Triticum iativum cullivés à l'obscurité'. Chez ces deux espdèes, l'accroissement des concentrations dc 2,4-D inhibe la germination ct la croissance.Des extraits de la coléopiile et de la premiére feuille d'Hordeum montrèrent une activitéélevée de l'auxine-oxydase, mais les extraits de Triticum furent inactils s'ils n'étaient pas additionnés de co-facteurs tels que MnCl2 et le 2,4-dichIorophénol: ils contiennent des inhibiteurs de la déradation enzymatique de l'auxine.L'addition de 2,4-D in vitro ne modifia pas la destruction de l'AIA par les extraita d'Hordeum ou de Triticum; l'inhibition du catabolisme de l'AIA, dans Hordeum, par des extraits bouillis de Triticum, ne fut pas modifie en présence de 2,4-D. L'activité tlr l'auxine-oxydase d'extraits d'Hordeum et de Triticum poussani en présence de 2,4-D fut exactement identique à celle des témoins, la comparaison etant faite stir la base d'un poids frais égal. L'inhibition, dans les exlraits de Triticum, ne fut pas affecteé par le 2,4-D.L'action herbicidedu 2,4-Dpursurses deux espèces, à l'obscurité, nepeut, en conséquence, èire expliqueté par une perturbation du cataboiistne de l'auxine par les auxines-oxydases. 2,4-dichlorophtnoxyacetic and and auxin catabolism in Hordeimi and Triticum

    Notes: Comparative Effects of 6-Furfurylaminopurine and 6-(γ, γ-Dimethylallylamino) purine on Growth, Peroxidase, Chlorophyll and Carotenoid Content. — 6-Furfurylaminopurine (FAP) and 6-(γ, γ-dimethylallylamino) purine (IPA) both inhibit root growth and cause an increase in peroxidase activity. When used at 10−8 and 10−8M, IPA stimulates elongation of the coleoptile test, at 10−4M both FAP and IPA provoke an inhibition. FAP and IPA maintain a high level in chlorophylls and carotenoids in floating leaves discs. In all these experiments, IPA has thus a higher effect than FAP.
