“…It is interesting that both genera have proportionally larger seeds than other Maloideae and inhabit tropical or subtropical evergreen forests of South Eastern Asia (Vidal, 1965;Kalkman, 1973). Larger seeds survive longer in forest understorey under reduced light intensity (Foster, 1986). Moreover, Eriobotrya cotyledons are photosynthetic, greening during germination (Ernst, 1906 (Herrera, 1989) and should became more important after the Middle Tertiary (Tiffney, 1984;Primack, 1987).…”

SUMMARYPhylogenetic relationships among 24 genera of Rosaceae subfam. Maloideae and Spiraeoideae are explored by means of a cladistic analysis; 16 morphological and anatomical characters were included in the analysis. Published suprageneric classifications and characters used in these classifications are briefly reviewed. Additionally, some new features are here reported, such as seed shape, presence or absence of endosperm, and number of cell layers in the seed coat and in the endosperm. Parsimony analyses indicate that Eriobotrya and Rhaphiolepis form a well-supported clade that is the sister to the remainder of the subfamily. This result is in agreement with published ITS sequence data. other clades are not supported, with the exception of the group Amelanchier-Peraphyllum-Malacomeles. Results of several studies point toward North America as centre of origin for Maloideae, considering the distribution of closely related Spiraeoideae such as Vauquelinia and Lindleia. A non-metric multidimensional scaling analysis of Takhtajan's biogeographic regions was carried out using presence/ absence of genera as characters. Eastern Asia is a centre of diversity from which the number of shared taxa decreases in several directions. This can be associated with the retreat of many taxa belonging to the Early Tertiary tropical-subtropical flora towards the refuges of China, Indochina and Malaysia, after wet-temperate forests were progressively transformed during the Neogene, which seems to be the case of Eriobotrya and Rhaphiolepis. Finally, Osteomeles and Chamaemeles were postulated as long-distance dispersion events while Hesperomeles could have originated in North America and migrated into north-western South America.

“…nutrients, defoliation, herbivores and pathogens) depends, in large part, by the amount of reserves originally available to the seedlings (Foster 1986, Mazer 1989, Houssard & Escarré 1991, Seiwa & Kikuzawa 1991, Milberg & Lamont 1997, Bonfil 1998, Tyler & Zohlen 1998, Naegle et al 2005. A number of studies have demonstrated that seed mass is a major determinant of seed reserves, and substantial seed mass variation exists at many scales (i.e.…”

We studied nutritional constraints on growth of Posidonia oceanica seedlings, morphometry and elemental content of mature seeds, and seedlings stranded on a beach of the northwestern Mediterranean Sea on 3 dates (May 2004, May 2005 and December 2005. The mean total nitrogen (N) and phosphorus (P) content of P. oceanica seeds was high compared with closely related species. Seeds varied considerably in mass, and their nutrient and carbon (C) content increased linearly with mass. This indicates substantial variation in the amount of reserves initially available for seedling growth. Stored reserves in seeds were used by seedlings within 6 to 8 mo after germination: P was retrieved with greater efficiency (86%) than was N (69%) and C (20%). From May to December of the 2nd year (2005), the tissue nutrient concentrations of seedlings declined due to fast utilization and translocation of nutrients from the internal pools to support summer growth. Instead the C concentration in roots and rhizomes increased, indicating an accumulation of C. Seedling tissue N and P concentrations were above the critical levels reported for seagrasses, and were also lower than those of plagiotropic rhizomes of P. oceanica collected in the same period. These results suggest that P may play a major role in constraining growth of P. oceanica seedlings.

“…Many studies have quantified patterns of seed destruction (reviewed in Janzen, 1971;Crawley, 1983;Fenner, 1985;Foster, 1986;Price and Jenkins, 1987;Hendrix, 1989;Louda, 1989). The most susceptible plant species tend to be relatively large-seeded and dependent on disturbance for population regeneration (Louda, 1989).…”
