The paper presents the results concerning a study on the influence of some biologically stimulators in a comparative crop in some dwarf French bean varieties used for seed production. The research works were carried out during the year 2012. Biological material under trial was represented by two dwarf Romanian varieties having green pods (Fantastica, Delicioasa de Pasarea) and one dwarf Romanian varieties having yellow pods (Margareta). Natural bioactive substances used in the experiments were: Cropmax 0.1% (four treatments on every 10-15 days), Kendal 0.2% (six treatments on every 7-10 days), Viva 0.4% (three treatments on every 15-20 days) and Benefit PZ 0.3% (on every seven days after pod setting). The variants were grown in an experimental field according to the method of subdivided plots with three replications. The observations performed concerning the phenology and morphological traits of the plants (plant pod number, pod length and weight of one thousand seeds) allowed an accurate characterization of the varieties under investigation as well an optimum recommendation for the growth regulators on the French bean crops. The processing of the production data of the seed crop was made according to the variance analysis. The influence of these treatments has been recorded both on the yield obtained and on the quality of the seed production. The results obtained show that the treatment applied with Cropmax and Kendal solution in a concentration of 0.1% and 0.2% increased the seed production by 35% and 30%. The paper presents data from the PhD thesis in the frame POSDRU/107/1.5/S/76888.
