Soybeans start flowering after they grow for 30 days (as for short - term varieties) or 45-50 days or more (for long term varieties). This stage lasts 15-20 days or even 40 days. It is the satge where the soybean is significantly affected by outside conditions. In some unfavorable conditions, the plants in general perform some mechanisms for the tolerance to them including the synthesis of some osmotic substances such as proline, glycine betaine. This paper studies the synthesis and the correlation between the proline and glycine betaine content of soybean leaves while the lower temperature, salt and drought conditions are treated in the flowering stage. The study was conducted on DT51 soybeans to define the content of proline and glycine betaine and then analyse the correlation between the proline and glycine betaine content. The result shows that there is the direct correlation between the proline and glycine betaine content of soybean leaves, which is proved by the linear regression equation: low temperature treatment: y1 = 1,83. x1 - 0,16 (R2 = 0,98); salt treatment: y2 = 2,47.x2 - 0,41 (R2 = 0,95) and drought treatment: y3 = 1,47.x3 - 0,18 (R2 = 0,99).
