Title
Allelopathic effect of aqueous extract of aerial organs and underground millet (Panicum miliaceum L.) on germination and seedling growth factors onion (Allium cepa L.)
Authors
Abstract
Allelopathic effect of aqueous extract of aerial and underground organs of millet and mixed with different concentrations on germination characteristics of the research onion petri dish in a randomized complete block with eight treatments and three replications in the laboratory of Horticultural Science, University of Jiroft was conducted in 1392. Treatments include organs extract groundwater and aerial mixture millet at four levels of 30, 50 and 70 %Weigh-Volume control (concentration 5%).
The results showed that the concentration of aqueous extract organs germination percentage, germination rate, root length, shoot length, fresh and dry weight, seedling vigor significantly decreased so that the concentration of 70 by %Weigh-Volume of extracts examined organs, especially the underground organs and their combination did not germinate. The maximum reduction in germination percentage of onion juice in the treatment of underground organs volumetric concentration of 70 %Weigh-Volume, The lowest effective concentration aerial (shoot) extracts in the treatment of onions in controls (5%), weight - volume was observed.
