Table 2 Effect of shading treatment on grain quality

From: Shading during the grain filling period increases 2-acetyl-1-pyrroline content in fragrant rice

Treatment Brown rice rate (%) Milled rice rate (%) Head rice rate(%) Protein content(%) Amylose content(%) Alkali grains with chalkiness (%) Chalkiness degree (%)
