The impact of road transport pollution of roadside territory on morphometric characteristics of major plantain (Plantago maior)

The purpose of the researches is the definition of influ-ence of M-53 highway in the vicinities of Krasnoyarsk on morphometric indicators of plantain (Plantago major L.) growing at the distance of 10, 50, 100 and 150 m from the roadbed. As control the species of Plantago major L growing at the distance of 300 m from the highway were used. The length and width of a leaf plate, the quantity of live and dried-out leaves, generative shoots, the length of an ear and generative shoot were measured. The rearches were conducted in 2016-2017. From pro-vided data it is evident that the plants of plantain from control platform have essential differences in the size of morphometric parameters from the plants growing near the highway (10 and 50 m from the roadside). The data obtained during the research showed that vegetating and generative species of plantain experience stressful influence from motor transport at the distance to 50 m from the roadbed of the route M-53. The most ex-pressed negative effect is established in 10 m from the roadside that confirms the majority of morphometric characteristics: the length and width of a leaf plate, the quantity of live and dried-out leaves, the length of an ear and generative shoots. On total number of generative shoots any reliable difference with control was not not-ed. The largest and numerous leaf plates, the maximum values of length of generative shoots and the quantity of flowers in an ear were noted at the distance of 300 m from the road edge.
