| The physiological changes and antioxidant enzyme activities of plug seedlings irradiated with 4 kJ${cdot}m^{-2}{cdot}d^{-1}$ UV-B or sprayed growth inhibitors of 50 ${cdot}L^{-1}$ diniconazole and 500 mg${cdot}L^{-1}$ hexaconazole for retarding the overgrowth of cucumber, tomato and hot pepper seedlings in summer season were investigated. Photosynthetic rate just after UV-B irradiation was significantly low but recovered to the level of non-treated seedlings 10 days after IV-B irradiation. And photosynthetic rate of chemical-sprayed seedlings was slightly lower in tomatoes but not different in cucumbers and peppers, compared with non-treated seedlings. Cholrophyll contens in the leaves showed no difference among treatments. Anthocyanin contents in the leaves of UV-B-irradiated seedlings were higher and no difference inchmical-sprayed seedlings, compared with non-treated seedlings. the activites of SOD(superoside dismutase), CAT )catalase), and POD(perosidase) of UV-B-irradated seedlings were higher thatn those of the non-irradiated seedlings just after UV-B irradiation. However. 10 days after UV-B irradiation, the activities were decreased to half of the value just after UV-B irradiation Whereasd the activies of chemical-sprayed seedlings were slightly higher than those of non-treated ones but lower than those of UV-B-irradiated one. |
