INFLUENCE OF LEVEL OF ATMOSPHERIC POLLUTION ON REPRODUCTIVE ABILITY OF CONIFEROUS TYPES
2018
Skok, A.V. | Rodionova, A.S.
coniferous types are very sensitive in city conditions to negative impacts of the industry and transport. The majority of industrial pollutions has harmful effect on vegetation. The research of level of pollution of free air was conducted by means of GANK-4 gas analyzer. The morphological variability of cones of a pine ordinary is studied (Pinus silvestris L.), results of a research of dependence of morphological indexes on the level of environment are given, results of a germination of seeds of a pine ordinary (Pinus silvestris L.), dependence of dynamics of germination of seeds on air pollution level phenol are considered. Pollution of the air basin phenol causes decrease of length, width, weight of cones, and mass of seeds of a pine ordinary (Pinus silvestris L.). Seeds correspond to the I class of quality. Seeds of a pine ordinary (Pinus silvestris L.) in plantings with the polluted air basin sprout rather intensively. On registration platforms low level of intra population variability of viability of seeds is observed. The negative trend of communication by phenol content in the atmosphere with amount of the sprouted pollen grains of a fir-tree prickly (Picea pungens E.), a positive trend of communication by phenol content in the atmosphere with amount of the sprouted pollen grains with two tubes (total, without branchings, with branchings) and amount of ungerminated grains is noted.
