外源喷施叶酸对稻米叶酸含量及品质的影响
Effects of exogenous spraying of folic acid on the folic acid content and quality of rice
摘要
Abstract
In this experiment,Yanjing 48 was used as the test rice material.The effects of exogenous folic acid spra-ying on the nutritional quality and growth and development of rice were explored by exogenous spraying of calcium 5-formyltetrahydrofolate and calcium 5-methyltetrahydrofolate at different growth stages:jointing,heading,and fill-ing.The results showed that when the application rate of folic acid was 225 g·hm-2,the contents of 5-FTHF,5-MTHF and total folic acid in rice were the highest,increased by 66.80%,52.43%and 13.20%,respectively.Meanwhile,at different growth stages of rice,compared with single-period spraying,the folic acid content of rice sig-nificantly increased after multi-period spraying.Additionally,folic acid application led to a reduction in amylose con-tent by 0.24-1.49 percentage points,while improving taste value by 4.44%-6.85%,increasing plant height by 2.99%-5.91%,and increasing yield by 2.95%-7.94%.These findings indicated that the application of exoge-nous folic acid not only increased folic acid accumulation in rice grains but also positively affected eating quality and agronomic traits during the development of rice.关键词
