Procedure to obtain different solvent extracts (APME, APEA, APET, and APWR) of Agriophyllum pungens seed.

The relationships between seed release of Agriophyllum squarrosum and mean maximum wind velocity (mean ± s.e.).

ABTS radical scavenging activity of different solvent extracts from Agriophyllum pungens seed: APME, 80% methanol; APEA, ethyl acetate; APWR, water; and APET, 80% ethanol. Data were presented as mean±SD (n=3). Means sharing different letters (a–f) are significantly different (P<0.05). Same extracts as created in . BHA (butylated hydroxyanisole), α-tocopherol and ascorbic acid at the concentration of 0.5 mg/mL were used as positive controls.

The number of seeds (mean ± s.e.) in aerial and soil seed banks of Agriophyllum squarrosum in April and August 2012. Bars with different upper case letters indicate significant differences between April and August within each seed bank type, and those with different lower case letters show significant differences between the soil and aerial seed banks within each month (P < 0·05), according to the l.s.d. test.
