Wheat allelopathy induced and enhanced by artificial breeding on the Loess Plateau of China
Based on field trials and laboratory assessment of evolutional wheat genotypes in 2002-2007 on the Loess Plateau of China, it was discovered that wheat allelopathy was induced and enhanced with the breeding history. Field investigation indicated wheat stubbles obviously suppressed weeds infestation while covering in sequent maize field, whose intensity depended on wheat genotypes and/or cultivars. It resulted from leaching allelochemicals during wheat straws decomposition. And furthermore, the more lately wheat accession was popular, the longer period functional allelochemicals activity persisted. These findings would be confirmed well by agronomic traits like high yield and physiological basis of fluorescence kinetics. Fm and F was induced to increase, particularly, photosynthesis system PS II would be expressed superiorly under drought press.
