Association mapping for total polyphenol content, total flavonoid content and antioxidant activity in barley

tailieu.vn

Results: A genome-wide association study (GWAS) was conducted for total phenolic content (TPC), total flavonoid content (FLC) and antioxidant activity (AOA) in 67 cultivated and 156 Tibetan wild barley genotypes. The markers bPb-0572 and bPb-4531 were identified as the major QTLs controlling phenolic compounds in Tibetan wild barley. Conclusions: GWAS is an efficient tool for exploring the genetic architecture of...

Allylphenoxypiperidinium halides as corrosion inhibitors of carbon steel and biocides

tailieu.vn

doi:10.3906/kim-2001-23 h t t p. The corrosion inhibition of the synthesized halides on carbon steel in water-salt-hydrocarbon environment, saturated with H 2 S, was investigated. The protection of different equipment from corrosion is one of the most important ecological and economic problems of petrochemistry, especially in environments containing hydrogen sulphide, CO 2 , salt, and other substances [1Ờ5]. While using...

under drought stress. In pot experiments, plants were grown under two different irrigation levels 70–80% and 30–40% of water holding capacity and foliar sprayed with putrescine at 0, 0.1 and 0.2 mM twice at 10 and 50 days after transplanting. Generally, medicinal and aromatic plants estimated about 49% of genera which habitat natively in Mediterranean region usually considered more tolerant...
