by applying various pesticides and boron compounds for two years, near
Ortaca-Muğla. The field sections were treated separately by commercial
pesticides and boron compounds i.e. tarimbor (TB), boric acid (BA), laser (LA),
zoom (ZO) and admiral (AD). During first year, <b> </b>boric acid (BA-1) caused
highest increase in total chlorophyll (TCh) content (158.41 μg g <sup>-1 </sup>)
while the second dose (BA-2) decreased it (103.11 μg g <sup>-1 </sup>). During
second year, higher doses of tarimbor
(236.49 μg g <sup>-1 </sup>) caused increase in total chlorophyll (TCh) while ZO
treatment decreased it (142.55 μg g <sup>-1 </sup>) (control: 149.55 μg g <sup>-1 </sup>).
TB-1 caused the highest increase in proline content (33.52 nmol g <sup>-1 </sup>)
while highest reduction was observed in boric acid (BA-2) (22.51 nmol g <sup>-1 </sup>)
as compared to control group (26.77 nmol g <sup>-1 </sup>). During the first
year, an increase of boric acid and tarimbor concentrations decreased
malonaldehyde (MDA) while during the second year, both increases and decreases
were observed in the MDA amount. Highest </span> <span lang="ru" style="font-size:11pt;line-height:115%;font-family:’Times New Roman’, serif;" xml:lang="ru">superoxide
