Responses of the conglutination function of achene mucilage in Artemisia sphaerocephala and Artemisia arenaria to electric field

NA Ri~1, YANG Sheng~2, HUANG Hong-yun~1(1.College of Science and Technology, Inner Mongolia University, Hohhot 010021, China; 2. Grassland Research Institute, Chinese Academy of Agricultural Sciences, Hohhot 010010, China)  
Under natural environmental condition, the achenes of Artemisia 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. The results showed that electric field treatment made the mucilaginous achenes hold more sand particles than CK; water absorption of the achenes became fast and dehydration of the achenes became slow; the electric field treatment increased the germination percentage of mucilage-intact achenes, but didn't affect the germination of mucilage-free achenes.
