Method for Assessing the Gas Resistance of Woody Plants
摘要
A method to assess the gas resistance of woody plants was developed based on the level of inhibition of the photosynthetic activity of leaves exposed to toxic gases in the laboratory and could be used to identify plants resistant to environmental pollution for further practical and breeding use. The effective quantum yield of photosystem II was used as an indicator of genotype tolerance. The sensitivity of the indicator was sufficient to differentiate control and experimental variants. The objects under study were ranked according to the degree of gas resistance. Recommendations were given for the practical application of the new method.
