Introduction:
Temperature is one of the main environmental factors that act on plants, affecting physiological processes such as germination and vigor, growth, photosynthesis, water and nutrients uptake, among others [1]. When seeds are exposed to temperature stress during imbibition process occur dramatic changes in the reorganization and function of the plasma membrane impairing the stability and functional structure of the membrane resulting in the decrease on germination and embryo death [2][3]. In plant, stress triggers wide response that extends from the change of gene expression and cell metabolism to changes in growth rate and productivity. The organism?s reaction is a function of plant capacity to produce effects opposite to the action of stressors [4].Conclusions:
We can conclude that homeopathy Arsenicum album 24x reduced the germination percentage, the length, fresh and dry biomass of sorghum. Probably the cause of this reduction is the lower absorption/water content in the system. The reduction in water content can be the cause lower values for the variables mentioned. However, the inhibitory action of the 24x dilution in water content is not yet known and will be one of the goals of future work.(AU)
