 Title    Schwermetalle in höheren Pilzen, II * Mangan und Eisen Heavy Metals in Higher Fungi, II Manganese and Iron  
 Abstract    In several series of 262 samples, Higher Fungi, especially from the Tremellales and Gastero-mycetes, were analyzed by atomic absorption spectroscopy on their content of the trace metals manganese and iron. Both elements were found to be present in higher concentrations in some species of the Trem ellales and P hallales. In the case of wood-destroying fungi, the Fe-and Mn-contents of the substrates were compared to those of the corresponding fungi. Only the species with the highest level of these metals reached the same contents as their substrates or a poor enrichment. Among the remaining species of the Higher Fungi, only in the case of the epigean P hallales, a possible biochemical role of manganese has been discussed.

 Title    Oxabetrinil Reversal of Metolachlor and Acid Soil Stress  
 Abstract    M etolachlor and excess M n:+ (acid soil stress) induce alterations in gibberellin precursor biosynthesis that can explain the morphological responses to these physiological stresses. O xa­ betrinil protects sorghum [Sorghum bicolor (L.) Moench] from the influence o f metolachlor and excess M n2+. Sorghum cultivar variations in response to excess M n2+ are explicable as dif­ ferential rates o f tvjf-kaurene biosynthesis between acid soil sensitive and tolerant cultivars. Concentrations o f M n2+ present in vegetative leaves and reproductive stem tissues were not different. Therefore, cultivar differences in e«/-kaurene biosynthesis explain the acid soil toler­ ance differences rather than differential M n2+ absorption, translocation, and/or compartmen-tation. M etolachlor and safener responses are found in cellular compartments and tissues that do not match a decreased herbicide concentration through absorption, transport, or degrada­ tion as a sole mode o f action for safeners.

 Title    Acceleration of Enzyme-Dependent Carthamin Formation by Manganese with Diversed Valence States  
 Abstract    Effect of manganese with three different valence states on carthamin formation was studied by using freshly collected flowers from dyer's saffron (C. tinctorius) capitula. A t 1 -10 hm con­ centration, these cations accelerated markedly the carthamin formation induced by endoge­ nous enzyme(s) in the detached floral tissues. The acceleration was obviously dependent on the valence state o f the test metals, more pronounced by M n (V II) or M n (III) than by M n (II) at a series o f given ionic strengths. O n a 1 |aM level, M n (V II) and M n (III) accelerated the pigment accumulation by faster o f 9 and 8, resp. than M n (II) during 5 min incubation at 30 °C. M n (V II) and M n (III) acted on both fresh and boiled florets, while M n (II) exerted preferential­ ly its activity on intact materials. Possible im plication of manganese ions on the enzyme-cata-lyzed carthamin formation are discussed.
