Phenological and physiological responses of hybrid rice under different high-temperature at seedling stage

Abstract

The projected increase in global temperature is expected to negatively impact food production in many regions. Rice exposure to heat stress can limit plant growth in different stages, especially at the seedling stage. In this experiment, two Indica parental lines N22 (heat tolerant) and BIM (heat sensitive) along with their F2 hybrid were elucidated under different high temperatures (28 °C, 35 °C, and 42 °C) at the seedling stage.
