Bidens Pilosa Seed Dispersal
The barbed spines of the achenes get stuck in the feathers fur fleeces clothing etc.
Bidens pilosa seed dispersal. Reproduction and dispersal bidens pilosa normally behaves as an annual weed but at least one form b. The infructescences form stellate spherical burrs about one to two centimeters in diameter. This study adds to our understanding of the timing involved in weed seed germination in agricultural lands and will contribute to the implementation of effective weed management strategies. These differences represent the combination of different adaptive strategies and may have ecological significance for the successful survival of b.
Bidens pilosa spreads by seeds. In this species the fruits have tiny barbed hooks or stiff bristles that enable them to readily stick on humans clothes or the fur and feathers of passing animals as a means of dispersal. Radiata may behave as a perennial. The study is aimed at providing details of sexual system breeding system pollination mechanism pollinators seed dispersal modes and germination aspects b.
Pilosa based mostly on field study. A single plant may produce up to 6000 seeds per year. A single plant may produce up to 6000 seeds per year. Pilosa and its success as a weed worldwide.
Barbs on awn of bidens pilosa. Seeds germinate on the soil surface or in shallow soil to a depth of 1 cm.
