Abstract
This study was conducted to find out the effect of diniconazole treatment by seed soaking on the stretching of tomato and cucumber seedlings. The emergence rate of tomato and cucumber seed was decreased as diniconazole concentration was higher and soaking period was longer. The emergence rate of tomato seedlings was lower as the soaking period was longer in $1mg{\cdot}L^{-1}$ concentration treatments, although there was no significant difference. The other concentration treatment (10, 50, and $100mg{\cdot}L^{-1}$) reduced emergence rate of tomato seedlings outstandingly in higher concentration and longer treated period, but 90% of treated seeds emerged at 10 days after sowing. As the concentration of diniconazol was higher and soaking period was longer, plant height and growth rate of seedlings were retarded. There covery of internodes growth was faster in lower concentration and shorter soaking period. The top and root fresh weight and dry weight of tomato and cucumber seedlings was not influenced by $1mg{\cdot}L^{-1}$ concentration, but these growth characteristics were reduced in higher concentration and longer soaking period. The dwarfed cucumber seedlings treated by diniconazol showed normal growth rate after planting and their male and female flower was set normally. These results suggest that the proper concentration and soaking period of diniconazol may be $10mg{\cdot}L^{-1}$ concentration for 12 hours in tomato seed, and $1mg{\cdot}L^{-1}$ concentration for 24 hours in cucumber seed.
