Plastic Relationships between Reproductive and Vegetative Mass in Solidago Altissima.
To test several predictions of a model of linear, size-dependent reproductive output in plants, we analyzed the relationship between shoot vegetative (v) and reproductive (r) mass in five experiments on Solidago altissima from an invading population in Switzerland. There was large environmentally-induced and genetic variation in r and v. A large amount of variation in r could be explained by va...
متن کاملOrigins, distribution, and local co-occurrence of polyploid cytotypes in Solidago altissima (Asteraceae).
There is growing realization that intraspecific polyploidy in plants has important implications for the evolution of plant diversity and for plant and plant-herbivore community dynamics. Nonetheless, the rate at which polyploid cytotypes arise and their fate in local mixed-cytotype populations are not well understood. Although within- and especially among-population cytotype variation has been ...
متن کاملIsolation and characterization of microsatellite loci in the invasive herb Solidago altissima (Asteraceae)1
UNLABELLED PREMISE OF THE STUDY Microsatellite markers were developed in the perennial herb Solidago altissima from populations within its introduced range in Japan to assess its population structure and to facilitate tracking of invasion expansion. • METHODS AND RESULTS Using 454 pyrosequencing, 16 microsatellite primer sets were developed for S. altissima. The primer sets were tested on ...
متن کاملAssociational resistance, gall-fly preferences, and a stem dimorphism in Solidago altissima
In most populations of Solidago altissima, a small proportion of plants have a growth pattern in which the stem bends early in the season so that the apex is pointing downward (i.e., a ‘‘candy-cane’’ stem) then straightens up again later in the season. The majority of plants, however, do not show this pattern. Instead their stems remain erect from emergence through flowering and senescence. It ...
متن کاملNutrient stress and gall flies interact to affect floral-sex ratio in gynomonoecious Solidago altissima (Asteraceae).
A main tenet of sex-allocation theory is that environmental stress should lead to increased maleness because reproducing through pollen is generally cheaper than producing fruits and seeds. Though this prediction has held for many species, it has been little tested for gynomonoecious plants, in which individuals produce both female and perfect flowers. We exposed eight ramets of each of 22 gene...
