We recorded the relative elevation, grass cover, and flower height of insect-pollinated plant species; the number of inflorescences; and the number of pollinators in a marmot colony on the Mongolian steppe.
Plasticity in the expression of all three phenological traits time from bolting to first flower, height at first flower, and total flowering duration was observed across manipulated bolting dates (Table 3).
The teasel, Dipsacus fullonum (Dipsacaceae) is a biennial herb, forming a rosette in its first year before growing quickly in the spring of its second year to a flowering height of between 0.5 2.5 m. [5].
Lines of both populations contrasted in many phenotypic traits, such as flower color, height of central stem, number and length of side branches, seed size, pod morphology, resistance to foliar diseases and nematodes, and many other characteristics.
In addition to the strong directional selective pressure on flowering stem height from both antagonists and mutualists, the height and density of the surrounding heterospecific vegetation matrix likely enhances this selection for taller flowering stems.
The number of days to flowering (DTF) was surveyed as the days needed from sowing to flowering, and height (HGT) was determined at maturity from the soil surface at the base of the culm to the top of the panicle.
In the subsequent GLM analysis (whole model: P < 0.0001; df = 3; AIC = 71.2; R = 0.29), initial fruit set was similarly affected by pollination treatment (P < 0.0001), but was significantly influenced by flowering stem height only for open-pollinated plants (interaction effect of treatment × the average flowering stem height, P = 0.02; main overall effect of height P = 0.11).
Future studies on the effects of flowering stem height on seed dispersal in response to local and landscape variation in vegetation density and height may provide additional insights into the functional role of selection on plant traits affecting floral displays.
Don't choose from pictures, but by flowering time, height, color and texture.
