A Biosystematic Study of Silphium Integrifolium Michaux ( Compositae ) 1 - 2
نویسنده
چکیده
Cytological and chromatographic data indicate that Silphium integrifolium Michx. is a rather homogeneous group of plants. Cytological study shows good pairing during meiosis in interspecific and intraspecific hybrids. Two-dimensional paper chromatography indicates that the varieties of S. integrifolium are more similar to each other than they are to two related species, S. asperrimum and 5. speciosum. The varieties of 5. integrifolium are chromatographically homogeneous.

Branching responses in Silphium integrifolium (Asteraceae) following mechanical or gall damage to apical meristems and neighbor removal.
Branching in plants increases plant access to light and provides pathways for regrowth following damage or loss of the apical meristem. We conducted two experiments in an eastern Kansas tallgrass prairie to determine how apical meristem loss (by clipping), apical meristem damage (by insect galling), and increased light availability affected growth, reproduction, and branching in Silphium integr...
متن کاملConsequences of habitat fragmentation for the prairie-endemic weevil Haplorhynchites aeneus.
Widespread destruction of tallgrass prairies in the midwestern United States has fragmented plant communities with the result that populations of endemic animal species have become geographically isolated from one another. The goal of the research summarized here was to evaluate the potential for conserving endemic prairie species of herbivorous insects by managing their host plants. Our study...

Genetic variation in a single species can have predictable and heritable effects on associated communities and ecosystem processes, however little is known about how genetic variation of a dominant species affects plant community assembly. We characterized the genetic structure of a dominant grass (Sorghastrum nutans) and two subordinate species (Chamaecrista fasciculata, Silphium integrifolium...

The green fruit of Solanum integrifolium Poir. has been used traditionally as an anti-inflammatory and analgesic remedy in Taiwanese aboriginal medicine. The goal of this study is to evaluate the anti-inflammatory activity and mechanism of the green fruit extract of S. integrifolium. A bioactivity-guided fractionation procedure was developed to identify the active partition fraction. The methan...

Multiple molecular forms of inhibitors of trypsin (TI) and chymotrypsin (CI), which are typical digestive enzymes of insects, mammals and micro-organisms, and subtilisin (SI), a proteinase of many bacteria and phytopathogenic fungi, were identified in seeds and vegetative organs of the majority of 128 wild and cultivated species representing 65 genera of three of the subfamilies of the Composit...
