Using Acid Mine Water for Removal of Phosphates from Sewage Effluent

An experiment was carried out at the Rondebult sewage purification works, regarding the use of underground mine water with a high iron content for phosphate removal from sewage effluents, to comply with a limit of 1 mg/ℓ soluble orthophosphates in the effluent. The theory of iron phosphate precipitation is discussed and reference made to phosphate removal plants in Wisconsin, U.S.A. Iron and aluminium salts did not seem to harm biological life on the filter. The dosing of mine drainage appeared to inhibit nitrification, reduce the pH increase through the filters, increase TDS by about 500 mg/ℓ, but an equivalent dosage of 20 mg/ℓ Fe maintained the final P below 1 mg/ℓ at a cost of 0,1 c/m3, one-tenth of the cost if chemicals had been used.

In Vitro Formation and Development of Floral Buds on Tobacco Stem Explants

Stem segments were excised from plants of Wisconsin 38 tobacco (Nicotiana tabacum L.) in three regions differing in their distance below the inflorescence. They were cultured in vitro in 8- or 16-hr days. After 8 weeks, floral and vegetative buds were counted, and extent of floral development was assessed. Kinetin at 10(-5)m inhibited formation and development of floral buds regardless of indoleacetic acid concentration. Supplied at this concentration with adequate auxin, kinetin stimulated vegetative bud formation and may have caused floral bud abortion. Indoleacetic acid (>/= 10(-6)m) inhibited vegetative and floral bud formation when supplied with low kinetin concentration (</= 10(-7)m) but did not affect floral development. When supplied with high kinetin concentration (>/= 10(-6)m), it inhibited floral bud formation and stimulated vegetative bud formation. More floral buds were formed in 16-hr days than in 8-hr days. Few formed on explants other than those derived from the region nearest the inflorescence regardless of other treatment.

Selective absorption of mineral elements by native plants of Wisconsin

Native plants of Wisconsin seem to show considerable selectivity in the absorption of mineral elements. This was indicated by an unusually high or low concentration of a specific element in a species in comparison with other species growing under generally similar conditions, and by the fact that a species might have an unusually high concentration of one or several elements but an unusually low content of other elements. A capacity for selective uptake of a particular element was in general characteristic of samples of the same species obtained from different sites. The potassium content of some accumulator species was as high as 7.0 per cent when the average concentration in other species from the same sample area was only 2.0 per cent. Manganese seemed to be selectively excluded by some species.Cornus canadensis, for example, collected from a bog of pH 4.0 contained only 149 ppm manganese in comparison with an average concentration of 1061 ppm in other species from the same area.Nemopanthus mucronata showed an unusual capacity for selective zinc accumulation. Samples of this species contained from 300 to 700 ppm zinc while comparison species from the same sites contained less than 50 ppm. Some of the nutritional and ecological implications of the results are discussed.

Notes on Wisconsin Parasitic Fungi. X

This paper is the fortieth which has been written in the course of the last sixty-thrce years on the general subject of the fungi which are parasitic on plants in Wisconsin. Wm. Trelease in 1885 published a preliminary list of Wisconsin paarsitic fungi. In the next half century J. J. Davis wrote twenty-six papers on this subject. Since his death in 1937 the studies have beCn continued by me. The notes in this paper, unless it is stated otherwise, refer to fungi collected durinig 1947.

A Chytrid Inhabiting Xylem in the Moline Elm

Species of such chytrid genera as Olpidium, Physoderma, Plasmodiophora, Synchytriuin, and Urophlyctis have long been recognized as parasitic inhabitants of superficial non-ligneous tissues in short-lived, herbaceous plants. Up to the present, however, only two chytrids have been recognized as inhabitants of deep, ligneous or vascular tissues. These two, both associated with diseases of sugar cane, are Ligniera vascularuml (Matz) Cook and a recently described but unnamed chytrid to which we shall refer as Carpenter's organism. It is our purpose to report the occurrence of a chytrid in the xylem tissues of a Moline elm,2 which in many respects resembles Carpenter's organism. In May, 1932, we received from E. L. Chambers, State Entomologist for Wisconsin, material from a diseased Moline elm. The tree was about 6 years old, had been grown by a Wisconsin plant nursery, and was one of a number set out 4 years previous as a boulevard planting in the city of Madison. The stock of the tree, American elm, presumably grown from seed by the nursery, had been budded with original Illinois Moline elm. Moline elms grown by the nursery in question had, except for this instance, shown no disease. This tree, however, had given evidence of disease or injury in its terminal shoot in 1931 and, in spite of pruning,
