Plant Introduction| Summary: | Pollen quality was investigated in four stands of Scots pine (Pinus sylvestris L.) and in four stands of Pinus pallasiana D. Don plantations. As ecologically safe territories we use 70-years plantation of P. pallasiana in arboretum of biosphere reserve Askania-Nova and 80-years stand of P. sylvestris in Kremenets forestry (Ternopil Region). The study has shown that pollen viability of both species in Kriviy Rih plantations was by 8 to 15 % lower compared to pollen of plants from other regions without man-made pollution. An increased (by times) number of abnormal pollen (ranging from 1.7 to 3.1 times for P. sylvestris and from 4.5 to 18.2 times for P. pallasiana) and abnormal pollen tubes at germinating (ranging from 3 to 4 times for P. sylvestris, and from 2.8 to 14.8 times for P. pallasiana) is characteristic for both species in Krivorizhzhya compared with the stands not exposed to pollution. These sensitive indicators of the pollen quality of both species can be used as an indicator for assessing environmental pollution in industrial lands. |
