Creator:: Erfan Ali, Shaikh Muhammad
Abstract:: The toxicity of aluminum (Al) to wheat (Triticum aestivum Host) was studied under controlled conditions using a technique designed to evaluate the recovery of root growth following a relatively brief (48 hour) exposure to nutrient solutions containing Al, When wheat seedlings were exposed to a minimum critical concentration of Al,...

Full Text:: Influence of cations on aluminum toxicity in wheat

Creator:: Henning, Stanley John
Abstract:: The progression and consequences of aluminum toxicity were studied microscopically in the root tips of four wheat varieties representing different classes of Al tolerance. The root tips studied were collected from seedlings grown in nutrient solution cultures containing either sublethal or lethal Al treatments which were unique for each variety....

Full Text:: -14(Major department) Title: ALUMINUM TOXICITY IN THE PRIMARY MERISTEM OF WHEAT ROOTS Abstract

Creator:: Rhue, Roy Dean
Abstract:: The time-concentration interaction of Al toxicity in the root meristems of Brevor wheat was studied using the L.D. 50 as a criteria for Al damage. The L.D. 50 represented a precise, well defined degree of biological damage which was easily reproduced under conditions where factors like temperature, pH, nutrient concentration,...

Full Text:: INTERACTION OF AL TOXICITY IN WHEAT ROOT MERISTEMS INTRODUCTION The primary effect of aluminum (Al) in wheat

Creator:: Lopez-Benitez, Alfonso
Abstract:: A technique previously designed to screen wheat cultivars and segregating populations for tolerance to Aluminum utilizing nutrient solutions in growth chambers was found to be efficient in differentiating among cultivars of wheat, rye, and triticale for tolerance to Al under greenhouse conditions. A 5°C increase in temperature, from 25°C to...

Full Text:: Influence of aluminum toxicity in intergeneric crosses of

Creator:: Kerridge, Peter Campbell
Abstract:: Wheat varieties of differential tolerance to Al were used in a series of nutrient solution experiments to study the inhibitory effects of Al on growth and nutrient uptake. The pH and the Al and P concentrations were rigorously maintained to prevent the confounding effects of Al and P precipitation and...

Full Text:: Aluminum toxicity in wheat (Triticum aestivum vill., host

Creator:: Bustaman, Sjahrul
Abstract:: Rainbow trout were exposed to aluminum at pH 7.25 and 8.25 and four hardnesses (10, 30, 80, and 120 ppm CaCO₃) for 96 hours in a continuous-flow system and mortality and aluminum accumulation in the gills were determined. Temperature, pH, and dissolved oxygen were measured daily for each treatment. Dissolved...
