Yunnan varieties have higher agronomic standards in SA1-SA2 (5-25mg/L), and SA2-SA3 (25-45mg/L), which is conducive to the accumulation of total chlorophyll content.

摘要为更系统地了解水杨酸对红花苗菜产量与品质的影响，本文以河南红花BH-1与云南品种红花为材料，采用0mg/L（SA1）、25mg/L（SA2）、45mg/L（SA3）、65mg/L(SA4)、85mg/L(SA5)等水杨酸浓度为梯度对幼苗进行叶面喷施，共喷施两次。第一次喷施在播种后14天，期间间隔七天进行第二次喷施。河南红花在SA2-SA3(25-45mg/L)时农艺性状、多糖含量水准较高，叶绿素含量在SA3（45mg/L）时含量较高、多糖含量，黄酮含量受到外源SA抑制。云南品种在SA1-SA2(5-25mg/L)时农艺水准较高，在SA2-SA3(25-45mg/L)时，有利于总叶绿素含量的积累。自然环境条件下云南品种种植到河南，受逆境因素与SA的影响，黄酮含量高于河南品种。关键词：水杨酸 农艺性状 叶绿素 有效成分<BR>
