【Objective】Temperature and exogenous arsenic are important factors affecting rice growth. Due to climate warming, rice growth is affected by a combination of temperature and arsenic in rice fields contaminated by arsenic. Clarifying the combination can provide a theoretical basis for rice management and safety production.【Method】Germination and culture experiments were carried out in the artificial climate chamber under the condition of different exogenous arsenic concentrations [0 (As0), 0.5 (As0.5) and 1 (As1) mg?L-1] and different temperature simulations [daytime/nighttime 30 ℃/25 ℃ (T0) and 35 ℃/30 ℃ (T1)] using eight common rice varieties in Jiangsu Province. Seed germination, seedling growth and arsenic uptake of different rice varieties were analysed. 【Result】The results showed that exogenous arsenic inhibited sprout length and vigor index of rice. Compared with T0As0, T0As1 reduced the sprout length and vigor index of different rice varieties by 13.69%-43.34% and 28.14%-52.88%, respectively, and the effect of temperature on rice seed germination was related to rice varieties. Under the condition of T1 treatment, the germination rate, sprout length and vigor index of Yanliangyou 1618 were better than those of other varieties. The interaction of temperature and exogenous arsenic significantly decreased the sprout length (P < 0.05). Compared with T0As0, T1As1 decreased sprout length by 5.66%-43.34%. Also, single temperature or exogenous arsenic had a significant effect on rice root length and root vigor. Compared with T0As0, T0As1 reduced root vigor by 3.01%-58.21%. The interaction of temperature and exogenous arsenic inhibited rice root length and root vigor. Compared with T0As0, T1As1 significantly reduced root vigor of different rice varieties by 53.80%-91.69%. The seedling height and root vigor of different rice varieties had significant differences (P < 0.05) under the same treatment of temperature or exogenous arsenic, among which the seedling height and root vigor of Yanliangyou 888 were at higher levels. The arsenic concentration in rice stems and leaves increased significantly under exogenous arsenic while the arsenic concentration in rice stems and leaves decreased under the increase in temperature. Furthermore, compared with single arsenic treatment, arsenic concentration in rice stems and leaves decreased under the interaction of temperature and exogenous arsenic. 【Conclusion】From the above results, it can be concluded that temperature and exogenous arsenic affected rice growth and arsenic uptake. However, rice growth conditions and arsenic concentration were significantly different among rice varieties. The germination and growth of Yanliangyou 888 and Yanliangyou 1618 were better than other rice varieties under the condition of temperature and exogenous arsenic.
