chinois. 为研究稀土对红花种子萌发和种苗初期生长的影响，给稀土用于红花的优质高产栽培技术提供生理生化依据，利用不同浓度稀土溶液浸泡红花种子，测定种子萌发和种苗初期的各项生理生化指标。结果表明：50mg／L和100mg／L的稀土溶液是处理红花种子的适宜浓度，能够促进红花种子的萌发，稀土能够提高红花的脱氢酶和硝酸还原酶的活性，有利于物质的转化，刺激胚芽与胚根的生长，有利于干物质的积累。[著者文摘]

Experimental results indicated that rare earth elements promoted seed germination, embryo growth, dry matter accumulation, seed vigor and index, substance degradation in seedling of safflower as a result of increasing activation of dehydrogenase and nitrate reductase in embryo and seedlings of safflower. The optimum concentration of safflower seeds was 50 mg/L and 100 mg/L of rare earth.
