| This experiment was performed to investigate the effect of UV-B (4 kJ${cdot}m^{-2}{cdot}d^{-1}$) irradiation and growth inhibitor (50 mg${cdot}L^{-1}$ diniconazole, 500 mg${cdot}L^{-1}$) treatment on the overgrowth retardation and the growth and yield afterplanting in plug-grown cucumber, tomato, and hot pepper sedlings. Stem length of UV-B-irradiated and iniconazole-treated seedlings was shortened by 38 and 35%^ in cucumber, 37 and 41% in tomato, and 23 and 23% in hot pepper, respectively, compared with non-treated seedlings. While retarding effect ofhexaconazole waslower that that of UV-B or diniconazle. Leaf area and dry weight alson decreased but ldaf thickness increased in UV-B irradiated or growth-inhibitor-treated seedlings. Even thouth the plant height and leaf area of UV-B-irradiated seedlings ant seedling stage were shorter and smaller that those ofnon-treatedd seedlings, they were recovered to the similar level to the growth of non-treated seedlings 20to 30days after trasplantin. The diconazole-and hexaconazole-treated seedlings were delayed recovery to their normal growth, Fruit yiedl of UV-V-irradiated hot pepper and tomato slightly increased but UV-B irradiated cucumer had similar yield to growth-inhibitor-treated one. It suggested that the use of UV-B irradiation could become a reliable tool of overgrowth retardation of plug-grown vegetable seedlings in greenhouse. |
