Germination under Saline Conditions’
Three mutant strains of Arabidopsis thaliana var Columbia were selected for their ability to germinate in elevated concentrations of NaCI. They were not more tolerant than wild type at subsequent development stages. Wild-type strains could not germinate at concentrations >125 mM NaCI. l w o of the mutant strains, RS17 and RS20, could withstand up to 225 mM, whereas RS19 was resistant to 175 mM....
متن کاملSaline/Sodic sub-soil on triticale, durum wheat and bread wheat yield under irrigated conditions
Sub-soil (> 30 cm) salinity and sodicity is a growing problem particularly in irrigated agricultural areas with rising water tables, poor water quality and/or deficient soil drainage. There were two objectives in this study; (1) to quantify the effect of sub-soil salinity and sodicity in grain yield of triticale, bread wheat and durum wheat and, (2) to determine if genotypes within and between ...
متن کاملEvidence for 1,8-dihydroxynaphthalene melanin in three halophilic black yeasts grown under saline and non-saline conditions.
The ascomycetous black yeasts Hortaea werneckii, Phaeotheca triangularis, and Trimmatostroma salinum are halophilic fungi that inhabit hypersaline water of solar salterns. They are characterized by slow, meristematic growth and very thick, darkly pigmented cell walls. The dark pigment, generally thought to be melanin, is consistently present in their cell walls when they grow under saline and n...
متن کاملGenotypic variation in phosphorus efficiency between wheat cultivars grown under greenhouse and field conditions
Phosphorus (P) efficiency (relative growth), which is described as the ratio of shoot dry matter or grain yield at deficient P supply to that obtained under adequate P supply, was compared in 25 winter wheat cultivars grown under greenhouse and field conditions with low and adequate P levels in a P-deficient calcareous soil. Adequate P supply resulted in significant increases in shoot dry weigh...
متن کاملPyruvate Kinase Activity of Wheat Plants Grown under Potassium Deficient Conditions.
The activity of pyruvate kinase was determined in the first leaves of wheat plants grown under K(+)-deficient conditions. An enhancement of the enzyme activity compared with the normal plants was found to start from eighth day of growth, and about 4-fold increase in the enzyme activity was observed in 14-day wheat leaves. The addition of K(2)SO(4) to the nutrient solution given to the K(+)-defi...
