Physiological responses of Betula pendula Roth growing in polluted areas
Plant functioning is affected by drought, extreme temperatures, heavy metal pollution and other unfavorable environmental conditions. High intensity of stress factors can be lethal to sensitive organisms or significantly decrease their condition. Intensification of stress factors is observed especially in urban and industrial areas. During the vegetative season plants purify the air and soil, d...

متن کاملEffect of Polluted Soil and Fertilisation on Growth and Physiology of Silver Birch (Betula pendula Roth.) Seedlings
One-year-old seedlings of silver birch (Betula pendula Roth.) were grown in pots filled with a soil substrate that originated from an area polluted by a phosphate fertiliser factory and characterised by a high soil Al level and low Ca/Al ratio or with a substrate from an area regarded as free from toxic pollution. In addition the effect of fertilisation with a mixture of nutrients was evaluated...
متن کاملCytogenetic Characteristics of Weeping Birch (Betula pendula Roth) Seed Progeny in Different Ecological Conditions
The present study of cytogenetic characteristics in seed progeny of woody plants in stress and no-stress conditions is important for better arrangement of green spaces in cities and reforestation on anthropogenically polluted territories because it allows to select maternal trees producing seeds resistant to stress factors. The following cytogenetic characteristics of the root meristematic cell...
