    Notes: Summary Tomato plants were cultured at various levels of rubidium and potassium in water culture. Growth as measured by dry-weight accumulation was reduced by the substitution of rubidium for potassium. The reduction in root growth was greater than the reduction in top growth; therefore, increased shoot/root values were noted with increasing rubidium concentration. In other experiments the potassium and rubidium content of the root and aerial portions were determined. It was found that rubidium tended to accumulate in the roots rather than the tops; it is postulated that this accumulation may be responsible for the observed inhibition of root growth. Potassium concentrations were similar in both the roots and tops indicating that the two cations did not behave similarly in these experiments.

    Notes: Abstract The dominant complementary genes in the oat variety Bond conditioning resistance to crown rust were isolated by selection from appropriately segregating F3 lines in a cross between the susceptible variety Fulghum and Bond. Their presence and mode of action was confirmed by F2 analysis when certain bulk F4 lines produced in this manner were intercrossed and when one such line was crossed with Bond. The value of these lines in confirming the proposed genotypes of certain other resistant varieties, which have genes interacting with, or allelic with, one of the Bond factors and in fundamental studies on the nature of rust resistance is pointed out.

    Description / Table of Contents: Zusammenfassung Studien über die Anreicherung von Mineralstoffen im Blattgewebe vom Mais haben gezeigt, daß bei einigen Elementen die Höhe der Anreicherung teilweise unter genetischer Kontrolle steht. Dieser genetische Hintergrund ist von viel weniger komplexer Natur als derjenige, der den Körnerertrag beeinflußt. Ausserdem ist die Höhe der Anreicherung in der Nachkommenschaft von Einzelkreuzungsbastarden im allgemeinen abhängig von den Inzuchtlinien, von denen sie abstammten. Die Höhe der Anreicherung gewisser Mineralstoffe scheint mit der Resistenz gegen die Dörrfleckenkrankheit (Helminthosporium turcicum Pass.) in Zusammenhang zu stehen. Zwischen allen untersuchten Mineralstoffen bestand nur eine einzige Relation. Es war die positive Korrelation zwischen Strontium und Kalzium. Untersuchungen der Genotypen mit hohem bzw. niedrigem Phosphorsäuregehalt von Böden verschiedenen Phosphorsäuregehalts zeigten, daß keine Wechselwirkung zwischen Genotyp und Düngungsstufe besteht. Für die meisten Mineralstoffe stimmt die Höhe der Anreicherung in den Hüllblättern der Maiskolben mit der in der ganzen Pflanze überein. Wenig Übereinstimmung war aber zwischen der Anreicherung der Mineralstoffe in den Maiskörnern und in den vegetativen Teilen der Pflanze vorhanden.
    Abstract: Résumé Des études sur l'accumulation d'éléments chimiques dans le tissu des feuilles de Maïs ont montré que le niveau d'accumulation de certains éléments est controlé partiellement par des facteurs génétiques. Ce facteur génétique est de charactère moins complexe que celui qui conditionne le rendement en grains du Maïs. En outre, le niveau d'accumulation chez les Hybrides de descendance de simple croisement fut lié en général au taux les lignes observé les quelles ils furent le produit. Le niveau d'accumulation de certains éléments semble être associé à la résistance contre l'helminthosporiose (Helminthosporium turcicum Pass.). De tous les éléments étudies, la corrélation du strontium et du calcium fut la seule relation valable. L'évaluation des niveaux hauts et bas chez des génotypes accumulant du phosphore, lorsqu'ils sont cultivés dans des sols à différentes teneur en phosphore, a montré qu'il n'y a pas d'interaction au niveau de fertilité du génotype x. Le taux d'accumulation dans les feuilles près des épis fut étroitement lié à celui de la plante entière. La relation entre l'accumulation d'éléments dans le grainét la partie végétale de la plante était insignifiante.
    Notes: Summary Studies of chemical element accumulation in leaf tissue of corn have shown that the level of accumulation is under partial genetic control. Differences in the accumulation level of some elements have been shown to have some relationship to resistance to corn leaf blight (H. turcicum Pass.). One can infer from the large differences in level of accumulation of chemical elements in the F3 from selected F2 plants, that breeding efforts to select for low accumulating genotypes for some elements could serve as a mechanism of reducing the intake of radioactive elements in the food chain should the level of these elements become serious.
