Dry Matter Partitioning and Salt Tolerance via Salicylic Acid Treatment in Strawberry Plant Under Salt Stress
Abstract
The objective of this
experiment was to investigate the effects of exogenous salicylic acid (SA) on
strawberry plants under NaCl stress. The
strawberry (Fragaria × ananassa Duch.) cv Kabarla was used in
the experiment. Until the beginning of the experiment, all plants were
irrigated with tap water and 1-month after planting, all plants were applied
with three different SA doses (1, 2 and 4 mM) and were watered with 35 mM NaCl
solution. Control and salt plants were not applied with SA, salt plants were watered
with NaCl solution and compared to controls. Three months after the salinity
(in March), salt stress decreased root volume by 37% compared to control. Overall, 4 mM SA and control had the highest
values of root tissue density (0.113 and 0.117 g cm-3, respectively).
Moreover, 4 mM SA treatment increased stomatal conductance by 87% compared to
salt plants. The dry matter was less partitioned to roots in salt stressed
strawberry plant. Dry matter partitioning between shoots and roots was
differently affected by supply of SA under salinity condition.
