    Growth, photosynthesis and storage of carbohydrates and nitrogen in Phaseolus lunatus in relation to resource availability (1995)
    Springer
    Oecologia 104 (1995), S. 17-23

    Notes: Abstract Growth, photosynthesis, and storage of nitrogen (N) and total non-structural carbohydrates (TNC) of a perennial wild type and an annual cultivar of lima bean (Phaseolus lunatus) were examined at different light intensities and N supplies. Relative growth rate and photosynthesis increased with light and N availability. N limitation enhanced biomass allocation into root rather than into shoot, while light limitation enhanced growth of leaf area. The TNC concentrations increased with light intensity and thus with photosynthesis, while the concentrations of organic N and nitrate decreased. Increasing N supply had the opposite effect. Therefore, TNC and organic N concentrations were negatively correlated (r=−0.90). Pool size of N or TNC increased with N and light availability when either resource was non-limiting, but increased little or remained constant when either resource was limiting. Storage reached a minimum when both resources were supplied at an equal rate.

    Nitrogen and carbohydrate storage in biennials originating from habitats of different resource availability (1993)
    Springer
    Oecologia 93 (1993), S. 374-382

    Topics: Biology
    Notes: Abstract Four biennial species (Arctium tomentosum, Cirsium vulgare, Dipsacus sylvester and Daucus carota) which originate from habitats of different nutrient availability were investigated in a 2-year experiment in a twofactorial structured block design varying light (natural daylight versus shading) and fertilizer addition. The experiment was designed to study storage as reserve formation (competing with growth) or as accumulation (see Chapin et al. 1990). We show that (i) the previous definitions of storage excluded an important process, namely the formation of storage tissue. Depending on species, storage tissue and the filling process can be either a process of reserve formation, or a process of accumulation. (ii) In species representing low-resource habitats, the formation of a storage structure competes with other growth processes. Growth of storage tissue and filling with storage products is an accumulation process only in the high-resource plant Arctium tomentosum. We interpret the structural growth of low-resource plants in terms of the evolutionary history of these species, which have closely related woody species in the Mediterranean area. (iii) The use of storage products for early leaf growth determines the biomass development in the second season and the competitive ability of this species during growth with perennial species. (iv) The high-resource plant Arctium has higher biomass development under all conditions, i.e. plants of low-resource habitats are not superior under low-resource conditions. The main difference between high- and low-resource plants is that low-resource plants initiate flowering at a lower total plant internal pool size of available resources.

    Notes: Durch thermischen Abbau von C8K sowie durch Umsetzung von Graphit mit Kalium und Rubidium konnten weitere Alkaligraphitverbindungen mit Alkalischichten in nur jeder 3., 4. oder 5. basisparallelen Schichtlücke des Graphitgitters erhalten werden. Die Zusammensetzung der 2. Stufe  -  bisher als C16Me formuliert  -  entspricht C24Me, die der folgenden Stufen im Idealfall C36Me, C48Me, C60Me.Bei allen Stufen haben die den Alkalischichten benachbarten Kohlenstoffschichten identische Lagen übereinander, während die anderen C-Ebenen wie im Graphit zueinander orientiert sind. Für die 1. Stufe, C8Me, wird ein neuer Strukturvorschlag entwickelt.Magnetische Messungen geben für die 1.-5. Stufe einen schwachen Paramagnetismus.

    Notes: Bei der Einwirkung von in flüssigem Ammoniak gelöstem Lithium, Natrium, Kalium, Rubidium und Cäsium auf Graphit oder bei der Umsetzung der bekannten Alkaligraphitverbindungen mit flüssigem NH3 entstehen sehr reaktionsfähige Graphitverbindungen, in denen Metallatome und NH3-Molekeln in das Gitter eingelagert sind. Es konnten bisher dargestellt werden: eine blaue Verbindung mit der angenäherten Zusammensetzung C12Me(NH3)2 und der Struktur einer 1. Stufe, sowie eine alkaliärmere, schwarze Verbindung, etwa C28Me(NH3)2 mit der Struktur einer 2. Stufe.Lithium, gelöst in Methylamin, gibt mit Graphit eine blaue 1. Stufe mit der Idealformel C12Li(CH3NH2)2.Durch die Einlagerung vergrößert sich der Abstand benachbarter C-Ebenen im Graphit von 3,35 auf 6,6 kX bei allen Ammoniakaten und auf 6,9 kX bei der Methylaminverbindung.
