Influence of Daylength Delivery on Flowering in Several Herbaceous Perennial Species

Glycinin composition of several perennial species related to soybean.

The 7S and 11S seed storage proteins from four perennials related to soybean (Glycine canescens, G. tomentella, G. tabacina, and G. clandestina) were analyzed by sodium dodecyl sulfate-gel electrophoresis. Each species yielded a unique electrophoretic pattern that varied in the total number of bands and their relative mobilities. In every case, the electrophoretic patterns were substantially di...

Life span correlates with population dynamics in perennial herbaceous plants.

Survival and fecundity are basic components of demography and therefore have a strong influence on population dynamics. These two key parameters and their relationship are crucial to understand the evolution of life histories. It remains, however, to be empirically established how life span, fecundity, and population dynamics are linked in different organism groups. We conducted a comparative s...

Response of Perennial Herbaceous Ornamentals to Meloidogyne hapla.

Sixty-nine herbaceous perennial ornamentals in 56 genera were evaluated for root galling after 2 months in soil infested with Meloidogyne hapla under greenhouse conditions. Plants were rated susceptible or resistant based on the number of galls present on the root system. Thirty-six percent had more than 100 galls on the roots (similar to 'Rutgers' tomato controls) and were rated susceptible. T...

Traits and climate are associated with first flowering day in herbaceous species along elevational gradients

Phenological responses to changing temperatures are known as "fingerprints of climate change," yet these reactions are highly species specific. To assess whether different plant characteristics are related to these species-specific responses in flowering phenology, we observed the first flowering day (FFD) of ten herbaceous species along two elevational gradients, representing temperature gradi...
