Strawberry plants (Fragaria × ananassa Duch.) are very susceptible to salinity. In order to investigate the interaction effects of paclobutrazol (PP<SUB>333</SUB>) and salinity on flowering, yield and fruit quality of strawberry plants, three levels of NaCl (0, 5, 10 mM) were incorporated into the nutrient solution and four levels of PP<SUB>333</SUB> [0, 10, 20, 30 ㎎·L¹] were sprayed. PP<SUB>333</SUB> application caused reduction in inflorescence length, but increased inflorescence and flower number. Salinity reduced number of achenes per fruit. However 10 ㎎·L<SUP>-1</SUP> of PP<SUB>333</SUB> ameliorated the diverse effect of salinity at 10 mM NaCl salinity and increased significantly the number of achenes per fruit. Interaction of 20 and 30 ㎎·L<SUP>-1</SUP> PP<SUB>333</SUB> with 5 mM NaCl, showed increase in yield in comparison with 0 and 10 ㎎·L<SUP>-1</SUP> PP<SUB>333</SUB> at the same salinity level. Total soluble solids (TSS) were increased at 30 ㎎·L-1 PP<SUB>333</SUB> in combination with 5 and 10 mM NaCl. also increased by this level of PP<SUB>333</SUB>. The highest level of PP<SUB>333</SUB> (30 ㎎·L<SUP>-1</SUP>) reduced titratable acidity (TA) on salt treated (5, 10 mM) plants. The ratio of TSS/TA tended to rise by application of PP<SUB>333</SUB>. Salinity reduced vitamin C, but 20 ㎎·L<SUP>-1</SUP> of PP<SUB>333</SUB> significantly increased vitamin C in both levels of salinity (5, 10 mM). Therefore from the results of this study, PP<SUB>333</SUB> application is recommended to increase reproductive growth, yield and improve fruit quality in saline condition.
