Dhaka Nov. 18, ’13, In an article titled, “Efficacy of ascorbate-glutathione cycle for scavenging H2O2 in two contrasting rice genotypes during salinity stress,” published in the November issue of Australian J. Crop Science the lead author Ashrafuzzaman at BAU and four other associates one of whom is affiliated with the Institute of Tropical Agriculture, Universiti Putra Malaysia,  have reported the results of their experiments in which they investigated the efficacy of ascorbate-glutathione cycle for scavenging H2O2 during salinity stress of 20-day-old seedlings of salt-tolerant Pokkali  and salt-sensitive BRRI dhan 29  rice genotypes. They treated the seedlings with  0, 75 and 150 mM NaCl for 7 days. Their results  revealed that salinity caused a significant decrease in photosynthesis rate (A), stomatal conductance (gs), chlorophyll content and shoot dry matter yield with a greater reduction in the sensitive genotype, BRRI dhan 29. They reported that in both Pokkali and BRRI dhan 29 during salinity stress the SOD (super oxide dismutase) activity, an H2O2generating enzyme increased.
