Effects Of Different Soil Salinity Levels On Germination And Seedling Growth Of Safflower (Carthamus Tinctorius L.), Mehmet Demi̇r Kaya, Ari̇f İpek, Ahmet Öztürk
Turkish Journal of Agriculture and Forestry
Safflower (Carthamus tinctorius L.) is rated as moderately salt tolerant and it can produce profitable crops on saline soils. It is slightly more tolerant of salinity than barley but is more tolerant than wheat. Because salinity reduces germination and delays emergence, safflower stands tend to be irregular and crop yield is depressed. However, some varieties are less affected by salinity than others. In this study, we aimed to determine the effects of soil salinity levels (0.8, 2.5, 5.1, 8.7, 13.0, 15.2 and 23.0 dS m^{-1}) on germination and seedling growth of three safflower varieties, one of which is spiny (5-154 …
