Abstract: Making use of water abstracts of internal of processing tomato are studied the oneself seedling growth experiment. Seen that the changement of seedling growth amounts, root vigour, degree of destroied cytogrease and cytomembrane of seedling, and the system of advance or defense of the cell enzyme on the different density of water abstracts. The results showed the seedling of processed tomato have some inhibiting lower on root length, stem length, fresh and dry weight of root, stem and leaf, root vigour have reduced obviously, The numerical value of cytomembrane permeate and MDA have enhanced obviously, showed that the cytomembrane have been damaged, In the system of advance or defense of the cell enzyme, SOD activity displays the trend reducing, the CAT activity displays the trend descending after increasing first, POD activity displays the trend rising, that trend have explained that defensive systems are destroyed protecting cytomembrane from peroxidation of cytogrease and cytomembrane.
