Proteins in rice embryos and endosperm accumulate protein bodies along the cell wall of the starch granules. Protein analyzers measure 59% of proteins, 19% of carbohydrates, 21% of lipids, and a portion of RNA and ash. In other words, the carbon source of rice strains' synthetic protein comes from carbohydrates formed by photosynthesis, so carbohydrates have a certain restriction on protein synthesis, and glutenin genes begin to express after 4-6 days of rice flowering.

Because the way and timing of protein accumulation is different from that of starch, this may be the reason why the weight of brown rice on the first day of flowering spikelets is heavier than that of protein spikes and the content of crude protein and weight of grains are negatively changed. The endosperm forms starch grains 2 to 3 days after flowering, and is rich in protein content, and accumulates at a rapid rate. At this time, some spikelets do not bloom in the ear, so the spikelets that bloom on the first day The more abundant nutrients, starch accumulation, and thus heavier grain weight.
In order to obtain good nutrient supply for different spikelets at different flowering times, it is necessary to provide good cultivation conditions before and during the growth of rice, and to cultivate a robust rice plant to lay a good foundation for subsequent flowering and fruiting. In addition, adjusting the planting time and paying attention to the regulation of fertilizer and water during rice flowering make the rice flowering in good environmental conditions. In addition, protein analyzers found a negative correlation between grain weight and crude protein content.
From the genetic analysis, the stable pure breeds and the genotypes of different grains in the same plant are the same. The result of the protein analyzer test showed that the formation of grain weight and protein, in addition to the influence of the genetic type of the cultivar, was also affected by factors such as flowering time, and the extent of the influence of crude protein content was more significant. Spikelets of different flowering time, due to environmental conditions and physiological changes in rice, thus affecting the supply of nutrients, resulting in brown rice grain weight, crude protein content differences.
