“…Allometry for reproductive tissues was seldom studied (Seki, 1994). This study used reproductive tissues as an individual biomass component, but no significant allometric relationships between reproductive tissues biomass and DBH or/and H were found (data not shown).…”

“…This study used reproductive tissues as an individual biomass component, but no significant allometric relationships between reproductive tissues biomass and DBH or/and H were found (data not shown). The possible reasons may be the dependency of reproductive tissue production on tree nutrition and associated environmental conditions (Seki, 1994) rather than on size.…”

“…However, it seems to diminish after a certain age ([140 years old) indicating the beginning of senescence. Seki (1994) found that cone production in A. mariesii in Japan increased as an exponential function of trunk diameter. Dodd and Silvertown (2000), however, correlated fecundity with tree age and DBH in A. balsamea in New York State and found that age was a non significant variable in all cases studied.…”

The reproductive biology of the endemic to Greece Abies cephalonica Loudon, including the phenology of the reproductive life cycle, cone production in relation to plant age and the required seed germination conditions, was studied. All individuals growing within 20 permanent plots of 100 m 2 each established in 11 different locations covering the entire strictly protected area of Mount Aenos National Park (Cephalonia) were monitored over a period of 4 years. The cones are formed on the upper part of the previous year's branches, mostly at the upper crown half of the reproductive individuals (over 53 years old). Female flowers are pollinated in spring and cone maturation lasts until the beginning of autumn, when seed dispersal occurs. The annual production of cones per individual varied significantly, revealing masting behavior for this tree. This behavior was also expressed in the number of trees producing cones, as well as the percentage of sound seeds per cone. A significant difference in the mass and the length of the cones between the years of low and high cone production was observed, being higher in the years of massive cone production. Similar germination percentages were observed in full darkness or under ''canopy light'' and ''sun light'', provided that the seeds were previously stratified for 6 weeks. It is concluded that A. cephalonica exhibits plasticity expressed in its reproductive behavior for alternating years of high to low cone production and in its seed germination for an array of habitat light conditions.

“…showed that age was a nonsignificant variable in all cases. Seki (1994) found that cone production in Abies mariesii in Japan depended upon the square of stem or branch diameter, but using a quadratic term for d.b.h. in our regressions did not improve r 2 significantly over the linear model and we used this.…”

Size-specific fecundity and the influence of lifetime size variation upon effective population size in Abies balsamea

The hierarchy of plant size often present in dense populations of plants and the close correlation found between size and fecundity can result in an unequal distribution of fecundity, which reduces the ratio of effective population size/census number (Ne/N). Such an effect has been found previously in annuals, but no study has hitherto tested for the effect in the lifetime fecundity variation of a perennial population. We use the demographically stable size distribution to be found in natural, wave-regenerating populations of balsam fir, Abies balsamea, in order to estimate Ne/N. In both wave-regenerating and normal forests our estimated values of Ne/N were about twice those previously reported for annuals. We suggest that fecundity variance is expected to be smaller in trees and other long-lived perennials than in annuals because density-dependent mortality operates more strongly in the prereproductive phase of long-lived plants.
