水稻品种植酸含量与稻米碾磨和外观品质的关系

THE RELATION BETWEEN THE PHYTIC ACID CONTENT AND MILLING AND OUTWARD APPEARANCE QUALITY IN RICE VARIETIES

水稻品种植酸含量不同，稻米的碾磨品质、外观品质存在差异．在早稻、中稻、晚粳类型品种和籼型杂交晚稻中，植酸含量与整精米率呈显著或极显著正相关；与碎米率、垩白率、垩白度、乳白米率呈显著或极显著负相关，其中籼型杂交晚稻的垩白率。

There are differences on milling quality and outward appearance quality in rice varieties of different phytic acid content .In early rice 、middle rice、late japonica varieties or late indica hybrid rice,the content of phytic acid has positive interrelation significantly or extremely significantly with head milled rice yield and a negative ones with the broken kernel yield 、chalkiness、chalkiness area and milky white grain yield ,but in late indica hybrid rice the relations with chalkiness and milky white grain yield are under significant level.
