Under natural environmental condition, the achenes of Arternisia sphaerocephala and Artemisia arenaria were treated with different electric intensity, to probe the variation of achene weight when the mucilaginous layer holds sand particles, the hydration and dehydration of the achenes, and the germination situation of mucilage-intact achenes and mucilage-free achenes.

用不同强度的电场处理沙生植物白沙蒿和沙蒿果实，在自然环境下研究电场作用后粘液物质将沙粒粘附于瘦果周围后瘦果重量的变化情况、果实水合与脱水情况、粘液果实及剔除粘液层的果实萌发情况。

In order to explore the mechanisms of auxin action and metabolism, as well as the changing characteristics of its relative enzymes, IAA content in strawberry fruits with different treatments was determined by HPLC. Content of IAA and the activity of IAO and POD in fruits treated by NPA or TIBA, the inhibitor of auxin transport, were analyzed to investigate the changing characteristics and possible source of auxin, as well as the relation among IAA, POD and IAO. Results were showed as the followings: there had a certain count of IAA in receptacles and achenes, and IAA content in achenes was higher than that in receptacles.

摘要为了探索草莓果实中生长素的代谢变化及其发挥作用的机理，利用HPLC定量测定了草莓果实发育过程中瘦果和花托中的吲哚乙酸，结合生长素运输抑制剂NPA和TIBA处理考察了草莓果实中IAA含量以及不同存在状态的生长素氧化酶和过氧化物酶活性变化，综合分析了草莓果实中IAA 的变化特性、可能来源及其与生长素代谢相关酶的关系。
