The effects of soil drought on photosynthetic and chlorophyll fluorescence in the leaves of two bean (Phaseolus vulgaris L.) genotypes were studied. The drought was imposed 14 days after plants growing up. The drought was imposed 14 days after plants growing up. The changes of content of photosynthetic pigments, leaf gas exchange and photochemical and non-photochemical quenching were studied. Data obtained suggest that genotype 91-089 is drought tolerant and cv. Veliko Tyrnovo is drought sensitive.
