“…However, in contrast to our results, the RDW reduction was higher or similar to the BMDW reduction [13]. Mondal et al also found a stronger effect on rice seedling roots than on coleoptile in relation to As stress [26]. The results of Shaibur et al indicated a higher sensitivity of rice shoots to As than roots in a hydroponic experiment [40].…”

Several studies have explored how arsenic (As) is absorbed and transported in plants, but less attention has been paid to its impact on rice growth and yield in relation to water management. We aimed to assess how arsenic affects plant development under different irrigation methods. The growth and yield parameters of four rice varieties (‘M 488’, ‘Janka’, ‘Szellő’, and ‘Nembo’) in two greenhouse experiments were analyzed in 2021 and 2022 under different irrigation methods (flooded (F), intermittent (I), and aerobic (A)). Three different As concentrations were set up in the soil: 43 mg kg−1, 24 mg kg−1, and 4 mg kg−1. Our results showed that the high As treatment caused severe damage to the plants including leaf yellowing as well as reduced growth and decreased yield parameters. Alternative water management practices such as I and A irrigation could reduce the negative effects of As. At the high level of As stress (43 mg kg−1), the I irrigation had the most favorable effect on the yield of 'Janka’ among the tested cultivars compared to the F irrigation (in F: 1.64 ± 1.13 g; in I: 5.45 ± 3.69 g). However, the use of fully aerobic conditions increased the likelihood of drought stress.

“…Coleoptile dry biomass was less influenced by As treatment. Different stress responses were detected among the tested cultivars in germination and growth parameters, as well as in As accumulation in rice seedling roots [26].…”
