Allelopathic potential and competitive traits of sweetpotato cultivars
نویسندگان
چکیده
Allelopathy and competition are components of plant-plant interactions, delimiting the level interference. Understanding this interaction has practical applications in agriculture. Crop cultivars possessing high allelopathic ability competitive traits themselves tools for sustainable weed management, enabling reduced use herbicides. Greenhouse field experiments were conducted to assess suppressive selected sweetpotato ( Ipomoea batatas L.) cultivars. The effect nine on Palmer amaranth Amaranthus palmeri S. Watson), junglerice Echinochloa colona L.), hemp sesbania Sesbania hederacea P. Mill.) was first evaluated greenhouse. experiment set up a completely randomized design with four replications twice. Sweetpotatoes cultured sand. target weeds seeded pots filled 2:1 mix soil:potting watered 100-ml aliquot root leachates once every 2 d. Weed height shoot biomass measured. ‘Heartogold’, ‘Centennial’, ‘Stokes Purple’ most Junglerice inhibited by leachates. Nine field. Experiments at Fayetteville Kibler, Arkansas, USA, split-plot design, infestation (broadleaf spp., grass or weed-free) as whole plot split-plot. Across locations, ‘Beauregard-14’ had longest vines, whereas ‘Hatteras’ ‘Heartogold’ tallest canopy. largest leaf area. This cultivar 2- 4-fold both locations. Yield average 55 68% broadleaf across respectively. ‘Bayou Belle-6’were high-yielding Kibler Fayetteville. highest yielding not but did incur yield loss from competition, indicating withstand Cultivar competitiveness, weed-suppressive ability, tolerance important factors that should be considered before making selection.

Lily Cultivars Have Allelopathic Potential in Controlling Orobanche aegyptiaca Persoon
As a devastating holoparasitic weed, Orobanche aegyptiaca Persoon. (Egyptian broomrape) causes serious damage to agricultural production and threatens economic development, which has raised widespread concern. The present study was conducted to determine whether lilies have the potential to be used as 'trap crops' for controlling O. aegyptiaca Persoon. In the experiments, the ability of three p...
