    The possible polyphyletic origin of copper tolerance inAgrostis tenuis (Gramineae) (1982)
    Springer
    Plant systematics and evolution 140 (1982), S. 109-117 
    Details
    ISSN: 1615-6110
    Keywords: Angiosperms ; Gramineae (Poaceae) ; Agrostis tenuis.—Evolution ; Copper tolerance ; genotype-environment interaction
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The effect of increased copper concentration in solution on the rooting of seven copper tolerant populations ofAgrostis tenuis has been examined using the regression technique ofFinlay &Wilkinson (1963). Three types of response to increased copper concentration have been detected, and it is suggested that these reflect a different genetic control of copper tolerance in different populations.

    The evolutionary breakdown of distyly inLinum tenuifolium (Linaceae) (1985)
    Springer
    Plant systematics and evolution 150 (1985), S. 291-301 
    Details
    ISSN: 1615-6110
    Keywords: Angiosperms ; Linaceae ; Linum tenuifolium ; Breeding system ; heterostyly ; self-incompatibility ; pollen production ; seed-set ; colonization
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Distyly inLinum tenuifolium L. is associated with a high degree of self-incompatibility. Breakdown in this system has occurred without the morphological rearrangement expected as the result of cross-over within the distyly supergene. Pollen-flow in both distylous and monomorphic populations is leptokurtic. A high proportion of intra-flower pollination occurs. Pollen production per ovule is reduced in the self-compatible race. Mean seed-set is increased. Individuals of the self-compatible race produce less vegetative growth and require a shorter time to reach reproductive maturity under cultivation. Increased fecundity appears to provide the selective advantage promoting the breakdown of self-incompatibility in this species. This is achieved through a massive shift of resources toward female reproductive function in plants of the monomorphic race. Subsequent colonization by this race has led to its increased distribution in C. & S. Europe.

    Variation and evolution inLinum tenuifolium (Linaceae) (1986)
    Springer
    Plant systematics and evolution 153 (1986), S. 243-258 
    Details
    ISSN: 1615-6110
    Keywords: Angiosperms ; Linaceae ; Linum tenuifolium L. ; L. suffruticosum L. ; L. salsoloides Lam. ; L. appressum Caballero ; Variation ; phenetics ; systematics ; evolution
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The phenetic variation inL. tenuifolium s.l. was assessed using multivariate analyses of 27 characters found to be variable within the species. These results are discussed and interpreted in the context of the reproductive biology, chromosome number and ecological responses of the taxa. Evidence suggests that both the self-compatible and tetraploid races were derived independently from a self-incompatible, diploid type. Although no taxonomic scheme is compatible with all of the evidence presented, the study supports a recent decision to recognize four taxa at subspecific level.

    Pollen flow, self-pollination and gender specialization: Factors affecting seed-set in the tristylous speciesLythrum salicaria (Lythraceae) (1987)
    Springer
    Plant systematics and evolution 156 (1987), S. 151-157 
    Details
    ISSN: 1615-6110
    Keywords: Angiosperms ; Lythraceae ; Lythrum salicaria ; Evolution ; heterostyly ; pollen ; gender specialization
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Some of the factors governing seed-set in three populations ofLythrum salicaria are examined during two seasons. Plants spatially segregated from legitimate neighbours by distances exceeding 1m set few seeds. Plants with small inflorescences set fewer seeds than those with medium or large inflorescences. Flowers having self pollen applied to the stigma before legitimate pollination set fewer seed per flower than those pollinated with legitimate pollen only. Seeds of the mid-style morph germinated more effectively than those of the long style morph and seeds of the short-style morph showed very low levels of germination.
