Phenotypes of low-temperature treated cultivar rice 93–11 after 5 days of recovery.

<p>Rice seedlings were cultured in a phytotron under light and temperature controls (the day/night cycle: 12 h with 25°C and 12 h with 18°C). The samples labeled as 24 h, 72 h and 120 h were treated under corresponding artificial low temperatures and recovered for 5 days under normal culture conditions. A, comparative phenotypes of 120 h low-temperature treated hybrid wild and cultivar rice after 5 days recovery. B, cultivar rice phenotypes of different low-temperature treatment times after 5 days of recovery.
