Soil development in the surrounding of oligotrophic mires in the Berlin region Polygenetic soils, surrounding oligotrophic kettle hole mires in the valley and aeolian sand areas of the Berlin region, were investigated. The typical soil catena is formed by the sequence of Ombric Histosol (Niedermoor), Ombric Histosol/Albi‐gleyic Podzol (Moor‐Podsol‐Gley), Albi‐gleyic Podzol (Nasspodsol‐Gley), Gleyic Podzol (Podsol‐Gley), and Dystri‐gleyic Arenosol (Gley‐Podsol‐Braunerde) (German soil classifications in parenthesis). Field and laboratory work showed, that the investigated soils were strongly related to each other and that their development depends on the trophy of the mire and groundwater fluctuations during the Holocene. Compared with the Bh‐horizon of terrestrial soils the Gh‐horizon is nearly free of Fe and Mn, but very rich in pedogenic Al‐oxides and rich in organic matter. The genesis of the soils is explained as follows: 1. The development of different Gleyic Podzols was due to rise of groundwater. Consequently the Bh and Bs horizons of Podzols surrounding the mire were converted to Gh and Gr horizons. 2. Humic substances and Al in the Gh and Gr horizons were not re‐mobilized due to the rise of groundwater, whereas Fe and Mn were reduced and removed by groundwater. 3. At the periphery of the mire Fe was enriched in the Go horizon of the Gley‐Podzols but not Mn. 4. The fact that the mire is completely surrounded by Podzol‐Gleys, indicates, that movement of the groundwater from the central parts of mires towards the periphery is an essential pedogenetic factor.  相似文献

Zusammenfassung Die Benennungssysteme für Kulturpflanzen und Wildpflanzen unterscheiden sich in wesentlichen Grundsätzen. Zu einigen Artikeln (15, 19, 26, 36) des Internationalen Code der Nomenklatur für Kulturpflanzen wird Stellung genommen.
Summary The naming systems for cultivated plants and wild plants are different in important principles. Some articles (15, 19, 26, 36) of the International Code of Nomenclature for Cultivated Plants are discussed.

Zusammenfassung Die Darstellung der infraspezifischen Mannigfaltigkeit von formenreichen Kulturpflanzen, besonders allogamer oder partiell-allogamer Arten, läßt sich ebenso wie die genealogischen Beziehungen innerhalb einer derartigen Sippe sehr schwer in einem taxonomisch-formalem System wiedergeben. — Es werden deshalb die Vorzüge informaler Verfahren für diese Fragestellungen herausgearbeitet; eine Merkmalstabelle, die die Merkmalsvariabilität beiVicia faba und das Auftreten der Merkmalskombinationen sowie ihre relative Häufigkeit angibt, demonstriert diese Betrachtungsweise.
Variability of characters withinVicia faba L., I. and II.
Summary The infraspecific manifoldness of variable cultivated plants, especially of allogamous or partially allogamous species, and the phylogenetical relations within such taxa are very difficult to be illustrated by a taxonomical system in a formal sense. Thus the advantages of an informal treatment have been stressed; this point of view has been demonstrated by a character table, in which the variability of characters, their combinations and frequencies of occurences were indicated for the speciesVicia faba.

Zusammenfassung Aus einer früheisenzeitlichen Vorratsgrube von Bösenburg (Kr. Eisleben) werden Reste von Kulturpflanzen und Unkräutern beschrieben. Gerste (Hordeum vulgare L. s. lat.) ist das vorherrschende Getreide. Daneben finden sich Emmer (Triticum dicoccon Schrank), Einkorn (Triticum monococcum L.), Spelz (Triticum spelta L.), Rispenhirse (Panicum miliaceum L), Lein (Linum usitatissimum L.), Pferdebohne (Vicia faba L.) und Unkräutenals Beimischungen. Der Spelz konnte für Mitteldeutschland erstmalig nachgewiesen werden. Dieser Nachweis und eine Zusammenstellung weiterer Funde zeigen, daß diese Art in prähistorischer Zeit eine wesentlich weitere Verbreitung hatte als bisher angenommen wurde. Die erreichbaren prähistorischen, genetischen, landwirtschaftlichen und linguistischen Daten über den Spelz machen wahrscheinlich, daß die Art ebenso wie Gerste, Einkorn und Emmer in Südwest-Asien entstanden ist.
Summary Remains of cultivated plants and weeds of early iron age are described from Bösenburg near Eisleben (Central Germany). Barley (Hordeum vulgare L. s. lat.) is the predominant cereal. Emmer (Triticum dicoccon Schrank), einkorn (Triticum monococcum L.), spelt (Triticum spelta L.), millet (Panicum miliaceum L.), flax (Linum usitatissimum L.), horse bean (Vicia faba L.), and weeds are found as admixture. Spelt was found in Central Germany for the first time. This find and a list of further finds prove a much more extensive prehistoric area of this species as assumed till now. The prehistoric, genetic, agricultural, and linguistic dates available on spelt show that this species originated in southwestern Asia as barley, einkorn and emmer.

Determination of the nutrient distribution in the soil-root interface by autoradiography A method is described to determine the nutrient concentration profile in soil in the vicinity of living plant roots. For this purpose plants are grown in flat boxes filled with radioactive labelled soil of 5 mm thickness and then autoradiographs of roots and surrounding soil are taken. The density of the x-ray film is scanned by use of a microdensitometer. The profile of the film density produced by 33P, which is a β-emitter of relatively low energy, represents the P concentration profile rather accurately. In case of 32P and 86Rb, nuclides of higher β-energy, profiles of the film density deviate markedly from concentration profiles because of cross fire. To account for the cross fire a corrective calculation is applied. The result of the corrective calculation is shown with autoradiographs of maize roots grown in either sand or loess soil labelled with 86Rb. Phosphate depletion zones around plant roots growing in soil usually do not exceed the distance of cross fire of 32P. Therefore, this nuclide is not or at least less appropriate than 33P.  相似文献

IR-Spectra of Microbial Biomass and Humic Acid from Podzol IR-examination of soil samples from podzol with or without different pretreatments was carried out in order to check the possibility of humic acid and microbial biomass detection. Pure humic acid and microbial biomass, both isolated or enriched from the soil under controle, showed distinct absorption bands or shoulders at 1730cm?1, 1620cm?1 and 1380cm?1. Only weak absorption bands at the respective wave numbers were detected in the untreated soil sample.  相似文献

Methods for relative quantifying fungi biomass in soils To estimate the mycological contribution in soil microflora, the amount of chitin and ergosterol and the decolorisation of Poly-B-411 dye was measured in three different soils. The tests showed a linear proportionality between the amount of soil and the respective quantities of the substances. Due to the methodic procedure, ergosterol was measured more accurately than chitin. The decolorisation of the Poly-B-411 dye was in wet humidic aerobic soil higher than in soil suspension. The stability of the adsorbance ratio (593/483 nm), which is a measure for the degradation, was obtained between the 5th and 7th day.  相似文献
