SCREENING OF THREE SAFFLOWER (Carthamus tinctorius L.) CULTIVARS UNDER BORON STRESS

Abstract

Excess of boron in soil and irrigation water is a serious constrain to crop production in many areas of the World as well as in Turkey. A pot experiment was carried out with to screen safflower cultivars in order to investigate the effects of boron toxicity stress on early growth and ions composition. Three safflower cultivars (Carthamus tinctorius cv. Balci, Yenice, Remzi Bey) were grown in pots containing alkaline and potassium rich soil, additionally supplemented with 0, 4, 8, 16, 32, 64 and 128 mg kg -1 boron. Chlorophyll content of all cultivars decreased with excessive boron levels. Plant height, shoot fresh and dry weight significantly increased at 4 mg kg -1 boron level followed by sharp decline with the other treatments. Boron content of cultivars increased and the highest amount was observed at 128 mg kg -1 boron level. Sodium content of all cultivars gradually increased with increase in B concentration. Whereas, potassium and calcium content reduced with increased B. Phosphorus content of all cultivars were least at 128 mg kg boron level. Results revealed that cv. balci appeared to tolerant to boron in soil up to 32 mg kg -1 and can be recommended for growing and breeding material for boron rich soils of Central Anatolia.

Effect of Boric Acid Application on Antioxidant Enzymes Activity and Gene Expression in Safflower (Carthamus tinctorius L.) Cultivars

“…Day and coauthors carried out a study on the effects of boron toxicity with the Remzibey, Yenice, and Balcı cultivars [65]. They found that the Balcı cultivar has the potential to be used for the phytoremediation of B toxic soils (including alkaline soils and those with high available K levels).…”

Aspir (Carthamus tinctorius L.) Çeşitlerinin Besin İçeriği Üzerine Farklı Kükürt Dozlarının Etkileri

“…With sulphur doses, K content was recorded between 0.56-0.60%. Potassium regulates the osmotic pressure of the plant and it has an important role in starch synthesis In similar studies related to the subject; Day et al (2017) determined that the K content was obtained between 45.4-72.1 g/kg from the Remzibey cultivar, while K content was obtained between 52.6-69.2 g/kg from the Yenice cultivar. In related to sulphur applications, Yılmaz (2017) determined that the highest K content was obtained as 4.67 % from 20 kg S ha -1 .…”

“…al., 2011). Day et al (2017) recorded that Ca content was determined between 7.7-11.0 g/kg from the Remzibey cultivar, while Ca content was obtained between 8.7-12.2 g/kg from the Yenice cultivar. In addition, it was recorded that obtained from control (0 kg S ha -1 ) applications as 1.22 % highest Ca content of canola plant, in a study carried out by Yılmaz (2007).…”

Identification and Morphologic Characterization of Some Salt Resistant Exotic Safflower (<i>Carthamus Tinctorius</i> L.) Lines During Seedling Growth

“…Sunflower is among the commonly cultivated oilseed crops in Türkiye [6,7] with a place among the alternative crops like safflower and others whose cultivation is increasing due to changing irrigation regimes, plant diseases, pests, salinity and boron toxicity problems. Safflower has deep root growth which enables the use of deep soil water; especially in areas suffering from salinity and it can also take part in crop rotation and phytoremediation to reduce salinity [8][9][10][11].…”
