Abstract:

In recent years, with the improvement of rice quality demand, the regulation of cultivation management on starch quality has become increasingly prominent. Here we systematically synthesize key starch metrics-pasting properties, crystallinity, granule morphology and amylose content, clarify the underlying physiology of photosynthesis, C-N metabolism and starch biosynthesis, and comprehensively evaluated the effects of fertilization, irrigation, temperature and light, planting density and harvest period on starch quality. Future work must integrate multi-factor interactions, gene-by-environment synergies and precision cultivation platforms to provide both the theoretical framework and technical support required for elite-quality rice production.

Key words: rice, starch, evaluation indicator, cultivation management
