【Objective】This paper is mainly to observe the changes of moisture state of grains during the growth process of rice after heading by LF-NMR, and investigate the effects of accumulation of starch and protein on the moisture state of kernels, which provides reference for formation regularity of rice qualities.【Method】The spikes of "Yueguang" organic rice were sampled at intervals for 63 days after heading(DAH), The 100-grain weight, hardness, moisture content, starch content and protein content were measured, separately, which were used to compare the changes of whole qualities of grains at different growth periods of rice after heading. The transverse relaxation parameters determined by LF-NMR were adopted to qualitatively and quantitatively analyze the moisture dynamics of grains. What's more, the internal relationships between the formation process of rice qualities and moisture state of grains were discussed.【Result】Both the 100-grain weight and starch content for "Yueguang" organic rice increased most quickly within 7-14 DAH, and they were highly significantly and positively correlated with each other(P0.01). Hardness was highly significantly and positively correlated with starch content and protein content, respectively(P0.01), and negatively correlated with moisture content(P0.01). Within 7-56 DAH, moisture content exponentially declined from 57.16% to 22.39%. With showing an S-shaped growth curve, starch content increased to 50.47 g/100 g wet-basis within 42 DAH. Protein content linearly increased to the peak value of 6.56 g/100 g wet-basis within 7-49 DAH. On the whole, the whole qualities of rice grains had been formed within 49 DAH. The inversion spectrum of LF-NMR data showed that part of water in the grains moved towards the direction of high mobility within 7 DAH. Within 7-21 DAH, when inversion curves of LF-NMR data gradually moved towards the left, T2 b peak representing for "bound water" with least mobility occurred, followed by the differentiation phenomenon of T22 peak representing for capillary water. Four kinds of transverse relaxation times including T_(2b), T_(21), T_(22) and T_(23), gradually decreased with growth periods, which indicated that whole proton degree of freedom in the kernels dropped obviously. The peak ratio of "bound water" was more than peak ratio summation of capillary water and free water at 21 DAH. The moisture content and transverse relaxation parameters(T_(2b),T_(21),T_(22),T_(23),A_(2b),A_(22) and A_(23)) of grains varied with growth periods highly significantly(P0.01), which were also highly significantly(P0.01) related to the accumulation of starch and protein. With endosperm cells filled with starch granules, most of water molecules in the grains were mainly surrounded by starch granules and formed hydrogen bonds with hydrophilic groups of starch, which resulted in the migration of moisture state towards the direction of "bound water". According to principal component analysis of transverse relaxation signals, there were significant differences among the moisture state of rice grains for different growth periods within 42 DAH, followed by keeping steady.【Conclusion】It was found that during the grain-filling process of rice, the moisture state of grains was significantly related to the accumulation of starch and protein. The ratio of "bound water" gradually increased, and the ratios of capillary water and free water significantly decreased in the grains. LF-NMR can be adopted to effectively analyze the whole moisture dynamic changes of grains at different growth periods of rice after heading.
