Aim: Plants are under the influence of environmental conditions from seed to
harvest. Many plant species are both stimulating these inconvenient conditions
and activating the defense system in order to keep alive. In this study, the
effects of irrigation water salinity and irrigation interval on total protein
amount of purple carrot plant were investigated.
Material and Method: In this study, purple carrot plants were grown in 6 different irrigation
water salinity (To =0,38 dS/m, T1 =1,5 dS/m, T2 =3
dS/m, T3 =5 dS/m, T4 =7 dS/m, T5 =10 dS/m) and
3 irrigation intervals (4 day, 6 day, 8 day). Leaf samples were taken from the
plants grown under the different stress conditions and the total amount of
protein was determined.
Moreover, soil samples were taken from each pot for
the determining the soil salinity
Conclusions: As a result of the study, it
was determined that due to the increase in irrigation water salinity increased
in soil salinity and decreased total protein amount of the plants. The increase
in the irrigation interval from 4 days to 6 days and 8 days; generally it was
observed more increase in soil salinity values. This result was caused in a
further reduction in the total amount of protein synthesized. A similar
relationship was found between plant yield and total protein. In the light of
this study, as a result of the stress caused by both salinity stress and
irrigation interval, the total protein amount affecting the yield in the plant
is important and if the protein synthesis is evaluated together with the
antioxidant enzymes which play a protective role, It is envisaged that the
stress mechanism can be analyzed, used to determine the optimum irrigation
interval and to plan yield estimates in limited irrigation studies.
