Abstarct: Most of the essential processes including like photosynthsis, biosynthesis of organic materials, enzymes formation, cell division and water and nutrients absorption are dependent on vitamins B complex. These vitamins are considered as an antioxsidants against oxsidative stresses. Nowadays some studies have performed about foliar application of micronutrients specially zinc and vitamin B complex in order to decrease undesivable enviromental effects on plants and improve their growth. Hope that these ways be effective in increasing the product growth. For this purpose, an experiment has been designed to study effect of pyridoxine, pantothenic acid and zinc pretreatments on quantitative and qualitative traits of green beans in research field of Shahrood University of Technology in 1395.Treatments were seed pretreatments with two levels of zinc (0, 10 μM), Three levels of pyridoxine (0, 0.02 and 0.04 %) and Three levels of pantothenic acid (0, 0.02 and 0.04 %) randomized in factorial experiment baxsed on RCBD design in 3 replications. For this purpose, the seeds were soaked in the solution for 12 hours and then dried in shade.The results showed that the use of Pantothenic acid 0.02 with pyridoxine 0.04% had a positive effect on dry matter accumulation, stem height, 100-seed weight and green yield. The interaction between the combination of pantothenic acid 0.04 and pyridoxine 0.02 % increased significantly compared to other treatments in the anthocyanin traits, sub branch and final yield. Also, the application of zinc10 mM with two concentrations of pantothenic acid 0.02 and 0.04% had a positive effect on the number of seeds per pod and the stability of the membrane, respectively. Seed pre-treatment with pentothenic acid alone, 0.02 and 0.04%, resulted in a significant increase in stem diameter, relative humidity, chlorophyll a, chlorophyll b, leaf area and qualitative traits. Also, the use of pyridoxine pre-treatment of 0.02 and 0.04% had a significant effect on some physiological traits such as chlorophyll b, total chlorophyll and relative humidity. Flavonoids were affected by the application of zinc 10 μM, Pentothenic acid 0.04% and Pyridoxine 0.04%. Generally, in performed experiment, pyridoxine of 0.04% and pantothenic acid of 0.02% were more effective on studied traits and pretreatments of pyridoxine, pantothenic acid and zinc led to improve the most of agricultural, physiological and qualitative traits of green bean.
