Pollen count count is by using a Burkard Trap, also known as the seven-day volumetric spore trap. This device works by facing towards the wind and drawing in air by using a pump. The pollen particles drawn in by the pump are then trapped by a sticky wax film that is attached to a rotating drum. The drum slowly rotates one turn over the course of seven days while collecting particles. The tape is removed after one week and cut into day-length sections. Pollen count Pollen count is the measurement of the number of grains of pollen in a cubic meter of
Resting spore Resting spore A resting spore is a resistant cell, used to survive adverse environmental conditions. Resting spore is a term commonly applied to both diatoms and fungi. A resting spore can be a spore created by fungi which is thickly encysted (has a thick cell wall) in order to survive through stressful times, such as drought. It protects the spore from biotic (microbial, fungal viral), as well as abiotic (wind, heat, xeric conditions) factors. It is found in "Anabaena". Resting spores of a particular fungus are known create the phenomenon known as late potato blight. They can lie dormant within
