黄花蒿对大蒜化感作用研究OA
Allelopathy of Artemisia annua L.on Allium sativum
为探究黄花蒿对大蒜鳞茎萌发及其幼苗生长的化感作用,用水提取黄花蒿叶、根、根际土壤,获取不同质量浓度的浸提液,用于处理大蒜鳞茎,测定大蒜鳞茎萌发率及其幼苗生长状况和叶绿素含量等指标.结果表明:随着黄花蒿水浸液浓度的升高,黄花蒿水浸液对大蒜鳞茎萌发率及其幼苗苗高、根长、叶绿素a和b含量、叶绿素含量、过氧化物酶活性、植株鲜质量、植株高的抑制作用不断增大,对大蒜幼苗丙二醛含量的促进作用不断增强;黄花蒿水浸液通过抑制大蒜鳞茎萌发率及其幼苗过氧化物酶活性、增…查看全部>>
In order to explore allelopathy of Artemisia annua L.on bulb germination and seedling growth of Allium sativum,bulbs of A.sativum were treated by different mass concentrations of water extracts from leaves,roots and soil around roots of A.annua.The bulb germination rate,seedling growth and content of chlorophyll of A.sativum were determined.The results showed that bulb germi-nation rate,seedling height,and root length,and content of chlorophyll a,content of …查看全部>>
