Arsenic concentration in initial soil, to which the above mentioned concentrations of arsenic were added, was 6.44 ± 0.24 mg kg-1.

The content of photosynthetic pigments in these five rice varieties did not differ significantly (p \u003e 0.05) from each other in control treatment though they differed significantly (p \u003c 0.05) from each other in 30 mg of As kg-1 soil treatment.

内容記述 | A glass house experiment was conducted to investigate the effect of soil arsenic on photosynthetic pigments, chlorophyll-a and -b, and their correlations with rice yield and growth. The experiment was designed with three replications of six arsenic treatments viz. control, 10, 20, 30, 60, 90 mg of As kg-1 soil. Arsenic concentration in initial soil, to which the above mentioned concentrations of arsenic were added, was 6.44 ± 0.24 mg kg-1. Both chlorophyll-a and -b contents in rice leaf decreased significantly (p < 0.05) with the increase of soil arsenic concentrations. No rice plant survived up to maturity stage in soil treated with 60 and 90 mg of As kg-1. The highest chlorophyll-a and -b contents were observed in control treatment (2.62 ± 0.24 and 2.07 ± 0.14 mg g-1 were the average values of chlorophyll-a and -b, respectively of the five rice varieties) while 1.50 ± 0.20 and 1.04 ± 0.08 mg g-1 (average of five rice varieties) of chlorophyll-a and -b, respectively were the lowest. The content of photosynthetic pigments in these five rice varieties did not differ significantly (p > 0.05) from each other in control treatment though they differed significantly (p < 0.05) from each other in 30 mg of As kg-1 soil treatment.
