摘要: Abstract A study was made of the total pollen production per individual tree in ten anemophilous arboreal species (including wild, cultivated and ornamental species) considerable aerobiological importance: Pinus pinaster, Ulmus minor, Juglans regia, Platanus hispanica, Quercus rotundifolia, Salix atrocinerea, Populus nigra, Acer negundo, Olea europaea Fraxinus angustifolia. For each three isolated well-shaped specimens medium height were chosen, number flowers grains anther estimated. The values varied between a little over 1000 million regia more than 500,000 one single rotundifolia. anther, oscillated 3000 100,000 europaea. There is an exponential correlation size anthers they contain. linear correlatio...
