Biostatistical Analysis on Fagopyrum Tataricum Gaertn

The effects of nitrogen application at different levels (0, 45, 135 and 225 kg/ha in 2015 and 0, 90, 180, 270 kg/ha in 2017) on the physicochemical characteristics of Fagopyrum tataricum Gaertn starch were studied by field experiments. Starch from Fagopyrum tataricum Gaertn with application of nitrogen showed lower amylose content, particle size, and retrogradation, and higher structure complexity, pasting temperature, gelatinization enthalpy, relative crystallinity, light transmittance, solubility of the starch. Nitrogen application did not change the ‘A’-type crystalline pattern of Fagopyrum tataricum Gaertn starch. This study indicated that nitrogen level and years and the interactions among nitrogen fertilizer levels and years significantly affected physicochemical properties of Fagopyrum tataricum Gaertn starch. The integrated results also provide some information into the management of the fertilization conditions to obtain starches with special properties for applications in food or non-food industries.
