Ailanthone inhibition data on seed germination and seedling growth of Lepidium sativum L. and Raphanus sativus L.

Ailanthone is a quassinoid from Ailanthus altissima (Mill.) Swingle with allelopathic properties that deserves interest for its potential use as a natural herbicide. Data about seed germination and root and hypocotyl length of two model species (Lepidium sativus L.ˈIngleseˈ and Raphanus sativus L.ˈTondo Rosso BIOˈ) treated with different concentrations of ailanthone are reported. Data derive from experiments performed in a growth chamber on filter paper, non-sterile urban soil, and a cultivation substrate for horticulture. Part of their elaboration and interpretation can be found in the research article titled “Ailanthone from Ailanthus altissima (Mill.) Swingle as potential natural herbicide” (Demasi et al., 2019).
