However, populations are greatest at the booting stage and decline as the plant matures. Although the low ability of smosl to produce tillers was not fully reversed in LRC1, this was however compensated by an increased grain weight per panicle , thereby achieving high grain yield per plant in the latter (Fig. NIH 126 kg N ha−1, 120 kg N ha−1, 72 kg N ha−1labeled with 30 atom% excess 15N were applied in … Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower).

Rice panicle temperature (T p) is a key factor for studying high temperature impacts on spikelet sterility.Comparing with measuring T p by hand, a T p simulation model could obtain T p data readily. Producing rice with an ideal panicle structure is an important direction for super high-yield breeding, and 1000-grain weight which determined by grain shape can also directly affect rice yield (Wang et al.

Cellular and physiological analyses revealed that the apical spikelets in the paab1-1 mutant undergo programmed cell death, accompanied by nuclear DNA fragmentation and accumulation of higher levels of H2O2 and malondialdehyde. With the completion of rice genome project, efforts are on to characterize the genes responsible for yield component traits such as the number of panicle-bearing tillers per plants, number of well-filled grains (spikelets) per panicle, and thousand grain weight with profound implications on yield improvement. In general, indica rice has a long and sparse panicle, whereas japonica rice has a short and dense panicle, which questions whether there is a diverse genetic basis of panicle architecture between indica and japonica rice.
