“…Overall, plant height, tiller number and root to shoot ratio tended to be less affected by elevating [CO2] rather than by elevating Ta (Table 1). Indeed, earlier studies also showed that elevated [CO2] had little affect plant height of inbred japonica rice species (Kim et al, 1996). Recently, however, Yang et al (2009) reported that elevated [CO2] could increase plant height of hybrid rice in China.…”

“…However, it is well documented that elevated [CO2] had a significant positive effect on tiller number of rice (Kim et al, 1996;Jitla et al, 1997;Yang et al, 2009). In particular, the stimulatory effect of elevated [CO2] on tiller number was pronounced in vegetative growth stage, while the effect became significantly small in reproductive stage due to the fact that a large portion of tiller produced was expired during reproductive stage (Kim et al, 2003).…”

Projected increases in atmospheric CO] tended to reduce (c. 6.6%) the LAI. At a given canopy layer, the LAI was affected neither by elevated [CO 2 ] nor by elevated T a , allocating the largest LAI in the middle part of the canopy. However, the fraction of LAI distributed in a higher and in a lower layer was strongly affected by elevated T a ; on average, the LAI distributed in the 75-90 cm (and 45-60 cm) layer of total LAI was 9.4% (and 35.0%), 18.8% (25.9%) and 18.6% (29.2%) in ambient T a , 1.3℃ and 3. 0℃ above ambient T a , respectively. Most of the parameters related to flag leaf morphology was negated with elevated [CO 2 ]; there were about 12%, 5%, 7.5%, 15% and 21% decreases in length (L), width (W), L:W ratio, area and mass of the flag leaf, respectively, at elevated [CO2]. However, the negative effect of elevated [CO 2 ] was offset to some extent by T a warming. All modifications observed were directly or indirectly associated with either stimulated leaf expansion or crop phenology under T a warming with elevated [CO 2 ]. We conclude that plant architecture and flag leaf morphology of rice can be modified both by Ta warming and elevated [CO 2 ] via altering crop phenology and the extent of leaf expansion.

“…High temperature during reproductive stage would result in decrease of grain yield by less number of spikelets produced per unit dry weight or nitrogen absorbed (Yoshida, 1983), lower spikelet fertility (Satake and Yoshida, 1978;Tashiro and Wardlaw, 1991;Kim et al, 1996a;Kim et al, 1996b;Matsui et al, 1997), and accelerated panicle senescence of grain (Kim et al, 2011). High temperature-induced spikelet sterility has decreased rice yield in tropical Asia (Osada et al, 1973) and Africa (Matsushima et al, 1982).…”

High temperature stress would affect rice production in the future as heat wave is expected to occur frequently under climate change conditions. The objective of this study was to obtain rudimentary information to assess the impact of heat stress on rice yield and its yield component in Korea. Two rice cultivars "Hwaseongbyeo" (Japonica) and "Dasanbyeo" (Tongil-type) were grown at different nitrogen fertilization levels in two seasons. These cultivars were grown in 1/5000a Wagner pot placed within four plastic houses where temperature was controlled at ambient, ambient+1. C. These results suggested that grain yield would decrease under future climate conditions due to grain weight decreased by shorter grain filling period as well as the ripened grain ratio reduced by spikelet sterility and early abortion of rice kernel development. Thus, it would be essential to use cultivars tolerant to heat stress for climate change adaptation, which merits further studies for developing varieties that have traits to avoid spikelet sterility and early abortion of rice kernel, e.g., early morning flowering, under heat wave.
