Effect of hymexazole (3-hydroxy-5-methylisoxazole) on cadmium stress and accumulation in Japanese millet (Echinochloa frumentacea Link)

Abstract

The mitigating effects of hymexazole (HMI), choline chloride, indolebutyric acid, ethephon and isoprothiolane on cadmium (Cd) stress and accumulation in Japanese millet were evaluated under aquatic conditions. Among five PGRs, HMI showed the highest mitigating effect; however, in this experiment, almost no effect of calcium (Ca), which has been demonstrated to be a Cd mitigator, on Cd accumulation was observed and the mitigating effect of Ca on Cd stress was less than that of HMI.

Exploring the Barnyard Millet (Echinochloa frumentacea Roxb. Link) Segregating Population for Isolation of High Yielding, Iron and Zinc Content Genotype

“…consistence performance. soils (Sherif, 2007;Abe et al, 2011). It is also cultivated at high hills under double cut production system with increased yield (Bandyopadhyay, 2009).…”

Restoration of Cadmium (Cd) Pollution Soils by Use of Weeds

“…Abscisic acid suppresses a decrease in chlorophyll content caused by Cd in Brassica napus, while 28-homobrassinolide mitigates the growth inhibition caused by Cd in Cicer arietium. According to a hydroponic test using white Japanese millet (Echinochloa frumentacea) conducted by Abe et al (2011), it was shown that HMI (3-hydroxy-5-methylisoxazole) at 2.5 × 10 3 mmol/l significantly reduced the growth inhibition (dry weight; % of control) of roots and shoots caused by Cd at 4.4 × 10 mmol/l from 4.2% to 23.9% and from 48.5% to 82.6%, respectively, while increasing Cd content (μg plant -1 ) from www.intechopen.com 0.32 ± 0.08 to 0.53 ± 0.04 in roots. This result indicates that Cd tolerance of remediation plants can be further enhanced by HMI.…”

Diversity and stability studies in barnyard millet (Echinochloa frumentacea (Roxb).Link.) germplasm for grain yield and its contributing traits

“…It can be grown with little use of water and it is alternate to water-guzzing crops. It has also been utilized for the reclamation of sodicity, arsenic and cadmium problem soils as it grows well under soil salinity condition and mitigates the cadmium stress; and increase the biosynthesis in plants Sherif and Ali (2007); Abe et al (2011). It is also cultivated at hills under double cut production system with better yield Bandyopadhyay, (2009).…”
