Changes in shrub fecundity in fourwing saltbush browsed by cattle
Shrub fecundity is critical to long term persistence of fourwing saltbush (Atriplex canescens (Pursh) Nutt.) populations at our research site on the shortgrass steppe in Colorado. We conducted a 2-year experiment to test hypotheses concerning the impact of cattle-browsing on fecundity-related variables in fourwing saltbush. Protection from cattle browsing was significantly associated with flora...
متن کاملHeifer Performance Under Two Stocking Rates on Fourwing Saltbush-Dominated Rangeland
The efficiency of livestock production in shortgrass steppe may be increased by grazing fourwing saltbush (Atriplex canescens [Pursh] Nutt)-dominated rangeland in late fall and/or early spring, but there is a paucity of information concerning stocking rates and animal gains. The objective of this study was to compare the effects of light and moderate stocking rates on weight gains of heifers gr...
متن کاملEcotypic Variation and Copper-Sensitive Mutants
A new vertical mesh transfer (VMT) technique has been developed to facilitate the rapid isolation of plant metal-tolerance mutants. l h e technique i s quantitative, allowing comparisons of the growth responses of different strains or ecotypes. Using the VMT technique, we have characterized the dose responses of 1 O ecotypes of Arabidopsis fhaliana to Cuz+, Znz+, NiZ+, Cr3+, Cd2+, and AI3+. Eco...
متن کاملChromosome Number Variation in Iranian Populations of Acorus calamus
Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...
