    Abstract


    A study on physiological and biochemical changes of germinating seeds and seedlings of two soybean varieties DT2008 and DT84 in low temperature conditions (80C, 120C, 160C and 250C as control) were carried out. The germinating seeds and seedlings were grown in Microclima chamber AXYOS E800 and the parameters were measured by the automatical devices connected to computers. The results showed that germination rate, chlorophyll fluorescence performance and photosynthetic intensity reduced markedly under the influence of low temperatures, while proline and glycine betaine content in sprouts and leaves increased dramatically. The ìnfluence of low temperatures expressed most clearly when the temperature lowered down to 80C and in the early days of the experiment.
