The Allelopathy of Aqueous Extracts from Galinsoga parviflora Cav. under Low Temperature Stress
低温胁迫对辣子草水浸提液化感作用的影响

The effect of low temperature on the allelopathy of aqueous extraction from Galinsoga parvifloraCav.was studied by using micronucleus assay in Vicia fabaroot tip cells.The results showed that the mitotic index of V.fabaroot tip cells treated with the aqueous extraction decreased and micronucleus and aberration rates increased under normal temperature.However,after G.parviflorawas treated at low temperature,the mitotic index of V.fabaroot tip cells soaking in low concentration of aqueous extraction enhanced ...
