“…Rice can be grown in different environments depending upon water availability and temperature conditions. For rice cultivation, the optimum temperature is between 25˚C and 35˚C, but it may change with genotypes, duration of the critical temperature, diurnal changes and physiological status of the plant [9]. Cold stress is a common problem that affects global production as a crucial factor in rice cultivation.…”

“…In Bangladesh, from October to early March, the usually low temperature prevails and or expected. At this time, the Boro rice, which is commonly known as winter rice suffers from a cold injury in different growth stages due to low temperature [9]. As the cold environment has numerous adverse effects on rice production, we should screen out cold stress-tolerant rice variety or varieties suitable for the Boro season cultivation prevailing the temperature 15˚C in Bangladesh.…”

A study was conducted to screen out the low-temperature tolerant Boro rice seedlings from November 2012 to January 2013 for facing the upcoming rice production challenge in Northwest Bangladesh. The experimental time was characterized by a prevailing low environmental temperature of below 15˚C. Five rice cultivars (V1: BR-2; V2: BR-16; V3: Pariza; V4: Minicate; V5: BRRI dhan 50) were selected for the study. The leaf proline, chlorophyll content and total carotenoid content were investigated. The V2 (BR-16) seedling synthesized the higher leaf proline (1.228 mg•g −1) at a low temperature than those of other tested cultivars. Again, the highest amount of chlorophyll-a (3.957 mg•g −1), chlorophyll-b (2.118 mg•g −1), chlorophyll-a/b ratio (3.6754 mg•g −1) and total chlorophyll (5.051 mg•g −1) was measured in V2 (BR-16). The maximum total carotenoid (1.213 mg•g −1) was also observed in V2. In this experiment, the V2 (BR-16) showed comparatively better potentiality to survive at low temperatures (below 15˚C) than other varieties.
