Kirje Effect of I2/KI water solution to wheat seeds imbibition assessed by image analysis(2018) Lev, J.; Blahovec, J.Water plays key role in a seed germination due to its participation in starting of many metabolic processes that accompany the seed germination. Rate of water uptake into seeds is a usual basis for determination of the three germination phases. The water uptake into seeds during their germination was investigated by many researchers who used various methods (e.g. magnetic resonance mic ro - imaging, near - infrared hyperspectral imaging and visualization with I 2 /KI solution (Lugol's iodine)). The method of using I 2 /KI water solution for this purpose is quite popular for its relatively applicability. In this paper we compared the seed surface area projection and shape development of the seeds imbibed in the I 2 /KI solution and in the pure water via image analysis. It was found that the presence of the I 2 /KI in water changes the increase of seeds volume during germination and the effect is diffe rent during the initial imbibition and during the next germination phases. The seed shape development is similar for both variants, pure water and I 2 /KI solution.
