%X An experiment was
carried out at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh
during the period from March to July 2014. Plants were grown in the rain</span><span style=\"font-family:&quot;\">-</span><span style=\"font-family:&quot;\">protected
polyethylene shelter or shed to avoid rain under natural conditions. The
experiment was conducted on biochemical characters of aus rice varieties in
various soil moisture levels in three rice genotypes as BRRI dhan55 (V<sub>1</sub>),
BR6976-2B-15 (V<sub>2</sub>)</span><span style=\"font-family:&quot;\">,</span><span style=\"font-family:&quot;\"> and
tolerant check Hashikalmi (V<sub>3</sub>)</span><span style=\"font-family:&quot;\">,</span><span style=\"font-family:&quot;\"> and
seven water stress w</span><span style=\"font-family:&quot;\">ere</span><span style=\"font-family:&quot;\"> imposed as treatments. Treatments were 0 days </span><span style=\"font-family:&quot;\">of </span><span style=\"font-family:&quot;\">water stress (control) irrigated continuously throughout the experimental
period (T<sub>0</sub>). From twenty days onwards water stress was imposed for
seven days when the age of the seedling was 20 days (T<sub>1</sub>), 35 days (T<sub>2</sub>),
55 days (T<sub>3</sub>), 75 days (T<sub>4</sub>), 95 days (T<sub>5</sub>)</span><span style=\"font-family:&quot;\">,</span><span style=\"font-family:&quot;\"> and 115
days (T<sub>6</sub>). Our findings suggest that the proline, starch</span><span style=\"font-family:&quot;\">,</span><span style=\"font-family:&quot;\"> and
sugar content w</span><span style=\"font-family:&quot;\">ere</span><span style=\"font-family:&quot;\"> also found comparatively higher in BRRI dhan55 and Hashikalmi among the
genotypes under water stress conditions. Un<span>der
water stress conditions</span></span><span style=\"font-family:&quot;\">,</span><span style=\"font-family:&quot;\"> proline w</span><span style=\"font-family:&quot;\">as</span><span style=\"font-family:&quot;\"> accumulated, sugar</span><span style=\"font-family:&quot;\">,</span><span style=\"font-family:&quot;\"> and starc</span><span style=\"font-family:&quot;\">h were decreased. The soluble sugar content was much lower under water
stress condition</span><span style=\"font-family:&quot;\">s</span><span style=\"font-family:&quot;\"> due to lower RWC, chlorophyll content, stomatal conductance</span><span style=\"font-family:&quot;\">,</span><span style=\"font-family:&quot;\"> and
higher leaf rolling. Leaf accumulates anthocyanins under drought conditions and
the red color increased as the intensity of water
