Natural plant hormone, Stimulates stem elongation by stimulating cell division and elongation. Stimulates bolting/flowering in response to long days.Breaks seed dormancy in some plants which require stratification or light to induce germination. Stimulates enzyme production (a-amylase) in germinating cereal grains for mobilization of seed reserves. Can delay senescence in leaves and citrus fruits. Use for seedless grape to improve berry size and in fruit thinning in different concentrations.
