Five species of columnar cacti were examined with the aim of introducing new orchard crops to the Negev desert of Israel. The species comprisedStenocereus gummosus, S. griseus, S. thurberi andPachycereus pringlei, all found in semi-arid regions of Mexico, andCereus peruvianus, which is grown in sub-tropical regions. Young seedlings were planted at four sites in the Negev. The sites differ in climatic conditions and water quality. Growth data, expressed as total stem length and stem biomass, was obtained after five to six years in the orchards. They showed thatC. peruvianus grew best in the site with moderate temperatures and good-quality water, whereas the other species also did well under more extreme conditions of high temperatures and brackish water. Growth of all species was significantly retarded at the site having water with the highest NaCl content. In the sixth year a severe drop in temperature at one of the sites caused extensive injury toC. peruvianus andS. griseus plants, raising doubts as to the suitability of that site for their cultivation. At this stageC. peruvianus is the most promising candidate for domestication. Its growth rate was much higher than that of the other species, yield was precocious and fruit of good quality. Stem tissue ion concentrations (dry weight basis) showed that accumulation of K+was similar at all four sites and that Na+and Ct were significantly higher (probably in toxic concentrations) at the site with the highest concentrations ofNa+and Cl~ ions in the water. At all sites Cl~ concentration inC. peruvianus was much lower than that in the other species indicating that the exclusion of Cl- from the stems was not correlated to salt tolerance.
