The allelopathic effects of Atriplex canescens (Four wing saltbush) on seed germination of Salsola rigida
Abstract One basic method of improving rangelands in a country is the use of native as well as exotic species of plants adaptable. Among the but introduced species, Atriplex canescens has been introduced in many rangelands, but it is important and necessary to consider it’s effects on native species. In the current study the effect of chemical competition (allelopathy) of Atriplex canescens o...
متن کاملNucleotide sequence of a cDNA from Atriplex canescens (Pursh.) Nutt. A homolog of a jasmonate-induced protein from barley.
The alteration in gene expression that occurs in plants subjected to water shortage has been documented extensively (Skriver and Mundy, 19901, and gene cloning and sequencing has shed some light on the molecular processes that may protect cells from the harmful effects of osmotic stress (Bray, 1991, 1993). Since plant hormones such as ABA and jasmonate are in some cases capable of causing expre...
