S. Zibai; A. Rahimi; H. Dashti DOAJ (DOAJ: Directory of Open Access Journals) 2012

Other claims from this paper (8)

Intervention effect Increasing salinity decreased dry weights of safflower aerial parts and roots, stem length, leaf area, and head dry weight.
Intervention effect Higher salinity shifted safflower dry matter allocation toward stems and heads and away from roots and leaves.
Intervention effect The safflower root/shoot ratio decreased significantly with increasing salinity.
Intervention effect Higher salinity significantly decreased safflower root dry weight.
Observation At 24 dS/m salinity, Goldasht safflower allocated more dry matter to shoots than to roots and leaves.
Intervention effect Higher salinity reduced safflower chlorophyll content and SPAD index.
Intervention effect Salinity above 16 dS/m significantly reduced safflower leaf area and plant height.
