Drought responses of rice (Oryza sativa) under various drought severity levels and durations in biotron and field

Abstract

Rice is an important staple food in human nutrition. Due to its semi-aquatic phylogenetic origin, rice is mainly produced in water intensive system. However, because of climate change, competition for water with other crops and modernization, rice production is becoming threatened by water shortage. Since drought is predicted to increase in the future, efforts have been made to develop drought adapted rice varieties. However genetic improvement has been slowed by the complex nature of drought and its strong interaction with the environment. Understanding the stress physiology will be a vital asset for the mitigation of climate change impacts in specific environments. This research project proposes to study physiological and grain quality responses of rice to various drought severity levels and durations in field and biotron environments.
