In order to study of
salinity effect on growth analysis of strawberry, a greenhouse
experiment was conducted in Vali-e-Asr University of Rafsanjan in 2010.
This study was carried out RCBD design with 4 replications to determine
the influence of salinity (30, 60, 90 Mmol and control with distilled
water) on strawberry growth analysis. Results indicated that relative
growth rate (RGR), crop growth rate (CGR), leaf area ratio (LAR) and
dry matter accumulation were decreased with increasing salinity. The
lowest RGR, CGR and LAR were observed in 90 Mmol NaCl salinity. Results
also indicated that maximum dry matter accumulations were observed in
1050, 1200 and 1400 degree days in 30, 60 and 90 Mmol NaCl salinity,
respectively. Water salinity more than 30 Mmol NaCl L-1 will
decreased fresh fruit yield more than 50 percent in hydroponics
strawberry production. Dry mass partitioning in NaCl-stressed plants
was in favor of crown and petioles and at expense of root, stem and
leaf whereas leaf, stem and root DM progressively declined with an
increase in salinity.
