The differences in morpho-anatomical, ecological and biochemical traits of Cyclamen coum subsp. coum, threatened plant listed in CITES (Convention on International Trade in Endangered Species of Wild Fauna & Flora) have been investigated in the central Black Sea region of Turkey in the context of its distribution at different altitudes. We found that shoot length, bulb width, leaf width and length, number of branches and flowers were significantly different along elevation gradient, whereas length of tubers, number of living and dead leaves, number of nodes, specific leaf area (SLA) and leaf mass area (LMA) values, did not differ significantly, PCA analysis revealed that leaf length and width, the number of branches, soil organic matter content and available potassium concentration and N concentrations of above and belowground parts and reproductive effort (RE3) played significant role in differentiation of the studied populations, while several other studied factor were found not significant. The reproductive effort of individuals from the sea level was higher. We suggest that significant differences in the studied traits may indicate the ecotypic differentiation among populations.

Since the contribution of total belowground bud bank and different bud types to community regeneration has rarely been explored, the vegetative offspring recruited from different belowground bud types was investigated in four plant communities along a grassland degradation gradient in northeastern China (Inner Mongolia). This gradient, between 1000 and 1500 m a.s.l., has been caused by overgrazing. It is a Leymus chinensis steppe which occupies about 3.0×10⁵ ha. Recruitment from tiller buds was dominant (>80%) in determining the total vegetative offspring density along the whole grassland degradation gradient. However, the proportional contribution of tiller-ramets to total ramet recruitment was significantly greater (P <0.05) during earlier than later stages of grassland degradation, while that of rhizome-ramets showed an opposite pattern. While the percentage contribution and density of root-derived ramets to total ramet density increased significantly (P <0.05) during the late stages of grassland degradation, those of bulb-ramets kept relatively constant along the whole grassland degradation gradient. The relative contribution of hemicryptophytes [i.e., Achnatherum sibiricum, Cleistogenes squarrosa, Festuca ovina, Koeoleria cristata, Poa annua, Stipa grandis] to total plant species richness decreased, while that of geophytes [i.e., Agropyron cristatum, Carex korshinskyi. Leymus chinensis, Allium anisopodium, A. bidentatum, A. tenuissimum, Astragalus galactites, Cymbaria dahurica, Iris tenuifolin, Potentilla acaulis, P. bifurca, Pulsatilla turczaninovii, Serratula chinensis, Thalictrum aquilegifolium] increased with the increases of grassland degradation. Our results showed that as grassland degradation increased, changes in the proportion of tiller-, rhizome- and root-derived ramets with respect to total ramet density determined in turn changes in the proportion of hemicryptophytes and geophytes in the study plant communities.

Allium oleraceum L. and A. vineale L. are two related bulbous geophytes with an annual storage organ that coexist in a wide range of habitats but show both partly different geographic ranges and habitat preferences in Europe. To explore whether ecological and distributional differences between species can be related to expected variation in some key life-history traits between them, research was undertaken to compare the phenology, seasonal growth, and dry-mass allocation of vegetative and reproductive plants of the species at successional gradient comprising three sites with contrasting environmental conditions (steppe, scrub, forest), where populations of the study species coexist (the Czech Republic). The results showed, in general, partly different timing of phenophases between species and different responses of species to contrasting environmental conditions. A. vineale displayed an annual life cycle similar to that observed in many Mediterranean geophytes, i.e. regularly sprouting above ground before the arrival of winter, its growth was concentrated into early and mid-spring and started to wither after a temperature increase and several short-term drought events in early summer, though its flowering was delayed until late June. A. oleraceum showed high year-on-year variation in the onset of shoot elongation above-ground; its growth was concentrated into mid- and late spring and its flowering was delayed until July. The patterns of phenology observed between the study species thus partly reflect selection under different environmental conditions of their origin. The total duration of the green above-ground period of reproductive plants in both species continued about 1.5–2 months beyond that of the vegetative ones. Over main growth period, mean relative growth rates (RGR) of A. oleraceum and A. vineale ranged from 20 to 22 and from 6 to 28 mg g⁻¹dw day⁻¹, respectively. A. vineale showed significantly higher RGR than A. oleraceum only in steppe conditions while at shaded sites the reverse pattern was found. The RGR of both vegetative and reproductive plants of A. oleraceum did not differ from one site to another. On the other hand, both vegetative and reproductive A. vineale plants showed lower RGR at shaded sites than at steppe one. Shading increased allocation into leaves in both species, caused complete abortion of developing scapes in A. vineale but only reduced reproductive allocation in A. oleraceum. A. oleraceum was able to maintain fitnessrelated traits more stably across the environments studied than A. vineale that fit well into the pattern of habitat differentiation observed between them in Central Europe. Data concerning growth of and allocation into new bulb in both species also support the hypothesis that allocating reserves for the coming year is the first priority in geophytes with an annual storage organ.
