Simulation and analysis of pollen coronas

Applied Optics, 1994
By numerical simulation of light scattering by birch and pine pollen grains, we create color plates of coronas with vertical elliptical shapes and strong brightenings, respectively. The shape of the pollen is modeled by the union of n ellipsoids. The Fraunhofer integral is solved by the use of the fast Hartley transform. The sensitivity of the patterns

Culture of Pollen Tubes for Chromosomal Analysis at the Pollen Tube Division

Stain Technology, 1953
It is possible to grow pollen tubes routinely for cytological analysis of nuclei at the pollen tube division. Pollen has been grown successfully after temperature, pressure, gas, moisture, and radiation treatments. The technic for growing Tradescantia pollen is described, but any method is satisfactory which ensures that: (a) the pollen is kept dry ...

On the theory of pollen analysis

American Journal of Science, 1963
A consideration of the theoretical relationship between vegetational percentages and the percentages of pollen in sediments makes it obvious that where species differ in the amounts of pollen they contribute to sediments, pollen diagrams cannot be interpreted quantitatively by means of traditional methods.
