最近在南加州的灌溉沙漠地区种植了球状洋蓟。这一地区的土壤由于应用咸水灌溉而具有或有可能成为高度盐分，因此，进行了为期两年的田间小区研究。用等量的氯化钠和氯化钙的水进行灌溉，施加了一个对照和五个生理盐水处理。测定了芽的产量和营养生长，两年来，相对芽产量不受影响，直到土壤盐度为6.1ds.m(-1)[饱和土壤浸出物的电导率(EC)]。单位盐度每增加6.1ds.m(-1)，产量下降11.5%。这些结果将朝鲜蓟置于中等耐盐性类别，减产主要归因于花蕾重量的减少而不是花蕾数量的减少，营养生长比花蕾生产对盐胁迫的耐受性更强，中脉和叶片组织中的氯浓度随着盐度的增加而增加。
Globe artichokes recently have been planted in the irrigated desert area of southern California. Soils in this area are, or have the potential to become, highly saline from the application of saline irrigation water, Thus, a 2-year field plot study was conducted. A control and five saline treatments were imposed by irrigation with waters that contained equal weights of NaCl and CaCl2. Bud yield and vegetative growth were measured, For the two years, relative bud yield was unaffected up to a soil salinity of 6.1 dS.m(-1) [electrical conductivity of the saturated soil extract (EC)]. Each unit increase in salinity above 6.1 dS.m(-1) reduced yield by 11.5%. These results place artichoke in the moderately salt-tolerant category, Yield reduction was attributed primarily to reduced bud weight rather than bud count, Vegetative growth was more tolerant to salt stress than was bud production, Chloride concentration in midrib and blade tissue increased as salinity increased.
