Effect of Microelement on Germination of Tomato Seed

This study took tomato seed as material,invested its seed germination vigor,germination rate,the dry weight of signal plant,G value and vigor index.The experiment was carried on to realizing the use of CuSO4,MnSO4,ZnSO4 etc.medicine in seed presoaking and its seedling growth.Result showed that among the certain range of the concentration,all the CuSO4 solution inhibit tomato seed germination while the germination percentage and germination vigor of tomato seed increased when the concentration of MnSO4 and ZnSO4 solution was at 0.1 g/L and 0.5 g/L.All of the 3 kinds of medicine can promote the seedling growth of tomato seed.Especially the concentration of Mn2+ solution at 0.1 g/L was the best within all of the medicine which was used in the experiment.Compared with the CK,its dry weight of signal plant,the G value and the vigor index was increase by 76.01%,75.29% and 85.75%.
