Rice races against rising temperatures

IRRI Seminar

By S.V. Krishna Jagadish
Scientist, plant physiology, IRRI

1315-1415 H, Thursday, 28 June 2012
Havener Auditorium, IRRI


Research on high temperature in rice over the past decade has focused primarily on the flowering stage, with little or no progress in research on the vegetative and other key developmental stages such as panicle initiation and gametogenesis. Research on rice response to short durations of exposure to intense heat at precise developmental stages continues to provide important knowledge. However, we understand little about aspects related to longer durations of stress and rice's ability to acquire thermo-tolerance. In addition, heat stress that shortens the grain-filling period strongly affects grain yield and quality.

In this presentation, Krishna will discuss the progress of research in tackling the problems mentioned above. Specifically, he will highlight a series of physiological and molecular studies spanning key developmental stages in rice. Economic losses associated with high-temperature-driven milling-quality outcomes and their implications under future warming scenarios will also be discussed.


IRRI Seminars are a forum for invited IRRI staff and guests to present information and their opinions on topics relevant to international rice research and the work of IRRI.
