Emission Rates , Survival , and Modeled Dispersal of Viable Pollen of Creeping Bentgrass

  title={Emission Rates , Survival , and Modeled Dispersal of Viable Pollen of Creeping Bentgrass},
  author={William F. Pfender and Rick Graw and William Bradley and Matthew C. Carney and Lara Maxwell},
Dispersal and deposition of pollen of creeping bentgrass (Agrostis stolonifera L.) was estimated by using CALPUFF, a complex model originally developed to simulate dispersal of particulates and other air pollutants. In fi eld experiments, peak pollen emission rates (8 × 106 pollen grains per min per m2 of a creeping bentgrass stand) occurred between 1000 and 1200 h. Pollen survival under outdoor conditions decreased exponentially with time, and only 1% survived for 2 h. CALPUFF simulations… CONTINUE READING
