    Notes: [Auszug] SIR - Genome size, as measured by the content of nuclear DNA per cell, varies over 2,500-fold among species of angiosperm plants1. As genome size is positively correlated with cell size and with the duration of cell cycle2, it may have direct effects on the evolutionary strategy3, life history, ...

    Photosynthetic and growth response to fumigation with SO2 at elevated CO2 for C3 and C4 plants (1982)
    Springer
    Oecologia 54 (1982), S. 50-54 
    Details
    ISSN: 1432-1939
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Six early successional plant species with differing photosynthetic pathways (3 C3 species and 3 C4 species) were grown at either 300, 600, or 1,200 ppm CO2 and at either 0.0 or 0.25 ppm SO2. Total plant growth increased with CO2 concentration for the C3 species and varied only slightly with CO2 for the C4 species. Fumigation with SO2 caused reduced growth of the C3 species at 300 ppm CO2 but not at the higher concentrations of CO2. Fumigation with SO2 reduced growth of the C4 species at high CO2 and increased growth at 300 ppm CO2. Leaf area increased with increasing CO2 for all plant species. Fumigation with SO2 reduced leaf area of C3 plants more at low CO2 than at high CO2 while leaf area of C4 plants was reduced more at high CO2 than at low CO2. These results support the notion that C3 species are more sensitive to SO2 fumigation than are C4 species at concentrations of CO2 equal to that found in normal ambient air. However, the difference in sensitivity to SO2 between C3 and C4 species was found to be reversed at higher concentrations of CO2. A possible explanation for this reversal based upon differences in stomatal response to elevated CO2 between C3 and C4 species is discussed.

    Effect of night temperature on daytime stomatal conductance in early and late successional plants (1982)
    Springer
    Oecologia 54 (1982), S. 76-79 
    Details
    ISSN: 1432-1939
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Sixteen annuals, biennials, and herbaceous and woody perennials characteristic of early and late successional old field ecosystems and upland and floodplain habitats were analyzed for their response of stomatal conductance to changes in night temperature. Early successional species that germinate in early spring when temperatures are low, but above freezing are insensitive to cool nights, i.e., their conductance in the following days is unaffected by low night temperature. Later spring and summer-emerging species' stomatal conductance is inhibited by low temperatures. Tree species show the same effects and in some an enhancement of stomatal conductance by low night temperatures was observed. However, adaptive differences in response to night temperatures appear related to both phenology of germination and growth and habitat types.

    Plasticity and genotypic variation in photosynthetic behaviour of an early and a late successional species of Polygonum (1983)
    Springer
    Oecologia 57 (1983), S. 270-273 
    Details
    ISSN: 1432-1939
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Rates of photosynthesis were measured in each of six replicated genotypes for each of two Polygonum species at five light and seven temperature levels. The early successional species, Polygonum pensylvanicum L., exhibited higher rates of photosynthesis and a more sun-tolerant behavior compared to its later successional relative, Polygonum virginianum L., results that are consistent with previously observed successional trends. Quantitative comparisons of individual genotype plasticity and between-genotype variation indicate that, in general, plasticity contributes more to population flexibility in photosynthetic response of these species than does between-genotype variation. However, the relative contribution of between-genotype variation was found to vary depending on the environmental variable and species studied. Between-genotype variation assumed greater importance in the temperature response than in the light response. Similarly between-genotype variation was more important in P. virginianum than in P. pensylvanicum supporting the notion that later successional species are less plastic. These results establish that significant levels of photosynthetic variation occur even within populations.

    Maternal regulation of fecundity: non-random ovule abortion inCassia fasciculata Michx. (1986)
    Springer
    Oecologia 68 (1986), S. 459-465 
    Details
    ISSN: 1432-1939
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary We examined the extent of ovule abortion and the within-fruit pattern of abortion inCassia fasciculata, an annual legume, and tested the hypothesis that abortion can result from competition for limited maternal resources among developing fruits and seeds. In a natural population at Mayview, IL, 53.4% of ovules in mature fruits matured as seeds; 43.4% showed some development but aborted, and 3.1% showed no development over virgin ovules. In a greenhouse experiment in which treatments were applied after most fruits were initiated, nutrient addition and partial root removel had no effect on abortion, but drought reduced the proportion of ovules maturing to 75% of the control mean. A fruit thinning experiment was conducted in which the number of fruits initiated on certain plants was limited. Control plants had more ovule abortion than fruit-thinned plants, suggesting that abortion resulted from competition for limited maternal resources. A “position effect” was observed in both field and greenhouse populations; ovules toward the fruit base (pedicellar end) had higher frequencies of abortion than those at the distal end. Thus, ovule abortion, like fruit abortion in this species, is non-random. Indivisuals regulate fecundity at both the whole fruit and individual seed levels.

    Photosynthetic acclimation to variability in the light environment of early and late successional plants (1982)
    Springer
    Oecologia 54 (1982), S. 313-316 
    Details
    ISSN: 1432-1939
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Fourteen plant species from early-, mid-, and late-successional habitats were grown for a period of 25 to 50 days in each of two light environments, i.e. full sunlight and in deep shade. The rate of photosynthesis for newly formed leaves was measured as a function of light intensity for plants from each light environment. Photosynthetic flexibility, measured as the difference in response between sun- and shade-grown plants, was determined for each of 5 parameters including dark respiration, quantum yield, light compensation, half-saturating irradiance for photosynthesis, and the photosynthetic rate at 1,400 μE m-2 s-1. We found photosynthetic flexibility to be high for early successional annuals, intermediate for midsuccessional species, and low for late successional species.
