| description | This research was conducted to examine the changes in growth and production of Oryza
sativa L. cv. Ilmi, which was
developed to cultivate high yielding rice variety in the Southern plains of Korea. The seedlings of the rice
were cultivated
from May to October in 2012 under three different conditions: control, AC-AT, ambient CO2 + ambient
temperature;
AC-ET, ambient CO2 + elevated temperature; EC-ET, elevated CO2 + elevated temperature. The aboveground
biomass,
belowground biomass, the total biomass of the rice, and panicle weight per individual were the heaviest in
the EC-ET.
But, the number of grains per panicle and the weight of one grain was higher at the condition of AC-ET and
EC-ET than
that of AC-AT. The number of tiller was higher at the condition of AC-AT and AC-ET than that of EC-ET.
However, there
was no significant difference in the number of panicles per individual and the ripened grain rate among the
control and
global warming treatments. Crop yield was the highest in the EC-ET. This result means that the global
warming condition
should be considered in the selection of suitable paddy field for the limibyeo in the future. |
