摘  要:
采用不同浓度瑞香狼毒提取物浸泡处理小麦种子,用恒温培养法测定适于种子萌发的药液浓度,通过田间试验调查小麦在分蘖期、拔节期和抽穗期条锈病的发生情况。结果表明,75.0 mg/L及以上浓度药液处理的种子不能萌发,30.0 mg/L及以下浓度药液浸种对萌发虽有一定影响但能达到较高的萌发率。田间试验调查结果显示,药液浸种后在小麦分蘖期不发生条锈病,在拔节期和抽穗期的病叶率均比对照低,差异达显著水平。

摘  要:
The extract of Stellera chamaejasme was used in wheat seed soaking,and the proper liquor concentration for seed germination was determined by constant temperature incubation.The results showed that the seed could not germinate if the liquor was thicker than 75.0mg/L;while high germination rate could be obtained when the liquor was thiner than 30.0mg/L.The effects of extract on rust incidence during tillering stage,jointing stage and heading stage was investigated by field trial.And the results revealed that after seed soaking,no stripe rust was occurred during tillering stage;and the deseased leaf rate during jointing stage and heading stage reduced significantly compared to the control.
