Carosello and the taxonomy ofCucumis melo L. especially of its vegetable races     

Hammer  Karl  Hanelt  Peter  Perrino  Pietro 《Genetic Resources and Crop Evolution》1986,34(2):249-259

Summary Carosello, a local vegetable from South Italy, is used in the same way asCucumis sativus but, in fact, it is a vegetable race ofCucumis melo. In the light of this local vegetable race which is presumed to be a relic of a former, more wide-spread cultivation, the infraspecific taxonomy ofCucumis melo together with some aspects of the history of melon systematics are discussed.Carosello is taken as an example to demonstrate that in the course of domestication of several completely unrelated taxa special varieties had been selected for the consumption of unripe fruits which are unpalatable when ripe in the majority of the cultivars of these species.

Carosello und die Taxonomie vonCucumis melo L. unter besonderer Berücksichtigung der Gemüsesippen

Zusammenfassung Carosello, eine lokale Gemüsesippe aus Süditalien, wird in der gleichen Weise wieCucumis sativus genutzt, ist aber eine Form vonCucumis melo. Im Lichte dieser lokalen Gemüsesippe, von der angenommen wird, daß sie das Relikt einer weiteren Verbreitung in früheren Zeiten ist, werden Fragen der infraspezifischen Taxonomie vonCucumis melo sowie Aspekte der historischen Entwicklung der Melonen-Systematik diskutiert.Carosello wird als Beispiel dafür herangezogen, daß im Verlaufe der Domestikation aus verschiedenen, nicht miteinander verwandten Taxa Sorten selektiert wurden, die im unreifen Zustand genutzt werden können, während sie zur Reife bei der Mehrheit der Sorten dieser Arten wenig schmackhaft oder sogar ungenießbar sind.

Mercury Cycling in Lake Gordon and Lake Pedder,Tasmania (Australia). I: In-lake Processes   总被引：1，自引：0，他引：1  

Bowles  Karl C.  Apte  Simon C.  Maher  William A.  Blühdorn  David R. 《Water, air, and soil pollution》2003,147(1-4):3-23

The processes affecting the concentrations of total mercury (total Hg) and methylmercury (MeHg) in a freshwater system comprising two connected reservoirs in southwest Tasmania were investigated. Surface concentrations of total mercury (total Hg)were temporally and spatially uniform in both Lake Gordon (2.3±0.4 ng L^-1, n = 27) and Lake Pedder (2.3±0.3 ng L^-1, n = 11). The surface concentrations of MeHg in Lake Gordon (0.35±0.39 ng L^-1, n = 25) were more variable than total Hg and MeHg typically comprised 10–20% of total Hg. The relatively high amount of total mercury present as MeHg in Lake Gordon was attributed to the high proportion of wetlandsin the upper catchment (50% of total area) and in-lake contributions (ca. 40% of total MeHg). Despite the close proximity of the two lakes, MeHg concentrations in Lake Pedder were consistently lower than in Lake Gordon. This phenomenon canbe explained in part by the greater contribution of direct rainfall to Lake Pedder leading to the dilution of MeHg. Water column MeHg concentrations were higher in warmer months in bothlakes, reflecting increased net methylation of inorganic mercury.Unlike previous studies of seasonally anoxic lakes, depth profiles of total mercury and MeHg in Lake Gordon were uniform and were not affected by water column stratification occurringin the summer months, and oxygen depletion with depth. This suggests that redox cycling and accumulation of MeHg in the hypolimnion following seasonally-induced anoxia is not a significant part of the mercury cycle in Lake Gordon. The primary location of MeHg production within the lake's water column is not conspicuous. Mercury speciation measurements made above and below the lake system over a period of 19 months indicates that after 20 yr of impoundment, the reservoirs are not significantly affecting MeHg concentrations in the downstreamriverine environment.  相似文献

Studies towards a monographic treatment of wild plant collections:Aegilops L. — resistance tests

Summary The monographic treatment of the GaterslebenAegilops collection (Hammer 1980b) is continued with the results of the resistance tests againstErysiphe graminis, Puccinia graminis, Puccinia striiformis, Puccinia recondita, Septoria nodorum andPseudocercosporella herpotrichoides. Against all diseases resistant strains could be found. Their possible use in breeding programmes is briefly discussed.

Zusammenfassung Die GaterslebenerAntirrhinum-Kollektion umfaßt mehr als 500 Sippen. Der größte Teil des Materials ist aus der MutantenkollektionStubbes hervorgegangen. Die Wildsippen stammen z. T. noch aus den Aufsammlungen vonBaur. Der aktuelle Stand der Kollektion wird in einer Aufstellung dokumentiert und Methoden ihrer Erhaltung werden diskutiert. Das Material wird im Hinblick auf interessante Eigenschaften für die Zierpflanzen-Züchtung charakterisiert.

The GaterslebenAntirrhinum collection

Summary The GaterslebenAntirrhinum collection contains more than 500 accessions. The largest part of the material has derived from the mutant collection created byStubbe. Partially the wild races can be referred to collections made byBaur. The content of the collection is documented in a list, and methods for its maintenance are discussed. The material is characterized with respect to characters interesting for ornamental plant breeding.

Missions for the collection of plant genetic resources in the Democratic People's Republic Korea 1986     

Kim Hjon-Sam  Karl Hammer  Han Un-Xoan  Peter Hanelt  Pak Hjong-Son 《Genetic Resources and Crop Evolution》1987,35(2):355-365

Summary Two collecting missions were carried out in the Democratic People's Republic of Korea in 1986 within the frame of the agreement between the Academies of Sciences of the DPRK and the German Democratic Republic. The first mission was concentrated on genetic resources of the genusAllium. 23 samples have been collected. The second mission included cereals, grain legumes, vegetables and medicinal plants and resulted in 145 accessions. The areas covered are rich in land-races of cultivated plants and their wild relatives. Promising material for research and breeding purposes was collected.

Zusammenfassung Zwei Sammelreisen wurden 1986 in der Koreanischen Demokratischen Volksrepublik innerhalb des Abkommens zwischen den Akademien der Wissenschaften der KDVR und der Deutschen Demokratischen Republik durchgeführt. Die erste Reise konzentrierte sich auf die genetischen Ressourcen der GattungAllium. 23 Proben wurden gesammelt. Die zweite Reise schloß Getreide, Körnerleguminosen, Gemüse und Arzneipflanzen ein und erbrachte 145 Sammelnummern. Die untersuchten Gebiete sind reich an Landsorten von Kulturpflanzen und ihren wildwachsenden Verwandten. Es wurde aussichtsreiches Material für Forschungs-und Züchtungszwecke gesammelt.

Nutrient balance in Scots pine (Pinus sylvestris L.) forest 1. Design of experiments     

Gunnar Abrahamsen  Karl Jan Erstad 《Water, air, and soil pollution》1995,85(3):1125-1130

The main objectives of the project described in the present and four following papers are:

1. To study tree growth and nutrient status of forest soil as influenced by atmospheric depositions of S and N.
2. To study the influence of plant growth, litter decomposition and atmospheric depositions on soil acidity.
3. To study the influence of atmospheric deposition on the release of N₂O from soil.

One field plot experiment in a Scots pine forest and one lysimeter experiment were established in 1990 on weakly podzolized soils (Cambic arenosol). The experiment was established in a young Scots pine forest. N, Mg and P were applied in a factorial design. The experiment includes 12 treatments and three blocks. Soil was collected in a long-term field experiment with acid rain and filled into lysimeters (bucket type) by horizon. Under each horizon tension lysimeters were installed. The lysimeters were under a roof to avoid input of natural precipitation. S was applied as sulphuric acid diluted to pH levels of 5.5, 4.0, 3.5 and 3.0 and applied in a quantity of 1000 mm ”rain” yr^?1. Nitrogen (NH₄NO₃) was applied in three quantities: 0, 30 and 90 kg N ha^?1 yr^?1. Seedlings of Scots pine were planted in the lysimeters. Lysimeters with no trees were also established. The experiment includes four replicates.  相似文献
