Project
Influence of elevated temperature and dry matter production and partitioning during grain filling in rice
Summary
My research is the area of climate change in agriculture particularly on the effect of elevated temperature on the source-sink relations in the rice crop. This research is aimed at understanding the pattern of plant growth (leaf and tiller development, dry matter production) in the different growth stages, and the subsequent partitioning of stored and currently produced assimilates to grains under high temperature conditions. This study will also look at the underlying physiological processes such as respiration, photosynthesis and stomatal conductance. While a broad range of temperature for good biomass production was reported, some scientists showed that 40°C/33°C (day/night) temperature is the limit for rice survival. Others showed that yield start to decline when daily mean temperature exceeds 29°C while changes in dry matter accumulation and partitioning can already be observed between 23°C-26°C. Variations among cultivars in terms of high temperature adaptations will also be observed and subsequent selection for traits and better cultivars will be explored to cope with the negative effects of rising temperature. She is from the Philippines, work as an Assistant Scientist at IRRI Philippines in climate change in rice, are at CSU on an ALA Scholarship (AusAID), and your research is linked with IRRI Philippines, University of Tsukuba in Japan, and DPI rice program in Yanco.
