“…In spite of several reports about volatile components in different species of Bothriochloa (Bhandari et al, 1993;De Wet and Scott, 1965;Kaul and Vats, 1998;Melkani et al, 1984;Pinder and Kerr, 1980;Scrivanti et al, 2009;Zalkow et al, 1980), only one study of their allelopathic potential has been published (Hussain et al, 1982). Nothing is known of the role of allelopathy in the normal development of communities with B. laguroides var.…”

“…An autoallelopathic effect is consistent with leachate suppression of germination on other species and reduced growth of buffelgrass seedling from neighboring plant root exudate (Hussain, Naqvi, and Ilahi 1982;Hussain et al 2011). It is possible that the leachate from the "older" thatch was less effective than from fresh thatch used in the field plots.…”

“…and Pennisetum americanum (L.) Leeke, which are closely related to buffelgrass (Hussain et al 2011). Buffelgrass root exudates also appeared to limit growth of neighboring buffelgrass seedlings (Hussain, Naqvi, and Ilahi 1982).…”

Buffelgrass (Pennisetum ciliare (L.) Link), a non-native perennial bunchgrass, invades ecologically intact areas of the Sonoran Desert. It competitively excludes native plants and increases fire frequency and intensity. Since the 1990s, whole buffelgrass plants have been manually uprooted and removed to control the invasion in southern Arizona. Uprooting plants results in bare, disturbed soil which promotes buffelgrass seed germination. This study examined whether leaving entire uprooted buffelgrass plants (thatch) on a field site reduces future buffelgrass establishment compared to removing uprooted plants from the site. A secondary goal was to determine whether light reduction and autoallelopathy were major factors in the negative effect of thatch on buffelgrass seedling density. Field plots with an average of 8,095 kg/ha thatch had 1.9 buffelgrass seedlings/m 2 which was significantly fewer than the 2.9 seedlings/m 2 in plots without thatch. Thatched portions of thatch plots (50% of their total area) had only 0.7 seedlings/m 2 . In the greenhouse, which reduced outdoor light intensity by 35.2%, buffelgrass seeds sown in bare soil resulted in significantly higher seedling density than beneath buffelgrass thatch. Potential autoallelopathic chemicals leached from partially decomposed buffelgrass thatch and leached thatch had an intermediate but not significant (p ¼ 0.09) effect on seedling numbers. Results suggest that leaving uprooted buffelgrass plants has the benefit of reducing seedling establishment in the area disturbed by uprooting. ARTICLE HISTORY

“…Most of these compounds are recognized for their allelopathic properties (Einhellig and Leather, 1988;Wó jcik-Wojtkowiak, 1992). As reported by Hussain et al (1982), the essential oil of Bothriochloa pertusa -from India -shows allelopathic effects inhibiting the germination of other plants. Bothriochloa species from South America exhibit great dominance in the area where they live, due to their effective reproduction and mode of colonization.…”
