Source 1’s ratings for tolerance to saline water spray:

Rating Definition
tolerant the growth of shoots is reduced by 25%, or more than 25% of leaves are injured, when plant is irrigated with water that has EC greater than 3 dS/m
moderately tolerant the growth of shoots is reduced by 25%, or more than 25% of leaves are injured, when plant is irrigated with water that has EC of 2 to 3 dS/m and which contains less than 425 ppm of sodium and less than 590 ppm of chloride
moderately sensitive the growth of shoots is reduced by 25%, or more than 25% of leaves are injured, when plant is irrigated with water that has EC of 1 to 2 dS/m and which contains less than 280 ppm of sodium and less than 360 ppm of chloride
sensitive the growth of shoots is reduced by 25%, or more than 25% of leaves are injured, when plant is irrigated with water that has EC of less than 1 dS/m and which contains less than 280 ppm of sodium and less than 360 ppm of chloride

Source 1’s ratings for tolerance to salinity of soil:

Rating Definition
tolerant leaves uninjured when the soil’s salinity, as indicated by ECe, is 8 to10 dS/m
moderately tolerant leaves uninjured with ECe of 6 to 8 dS/m
moderately sensitive leaves sustain minimal to recognizable injuries when the soil’s ECe reaches 3 to 6 dS/m
sensitive leaves sustain minimal, if any, recognizable injuries with ECe of less than 3 dS/m

Source 2’s ratings for tolerance to saline water spray:

Rating Definition
highly tolerant no symptoms of salt-related stress observed when irrigated via overhead sprinklers with water containing 600 mg/L of sodium and 900 mg/L of chloride
tolerant no symptoms of salinity-induced stress observed when irrigated via overhead sprinklers with water containing 200 mg/L of sodium and 400 mg/L of chloride
moderately tolerant symptoms of salinity-induced stress observed on less than 10% of leaves when irrigated via overhead sprinklers with water containing 200 mg/L of sodium and 400 mg/L of chloride
sensitive symptoms of salinity-induced stress observed on more than 20% of leaves when irrigated via overhead sprinklers with water containing 200 mg/L of sodium and 400 mg/L of chloride

Source 2’s ratings for tolerance to salinity of soil:

Rating Definition
highly tolerant no symptoms of salt-related stress develop, even when the soil’s salinity, as indicated by ECe, exceeds 6 dS/m
tolerant no symptoms of salt-related stress develop with ECe of 4 to 6 dS/m
moderately tolerant no symptoms of salt-related stress develop with ECe of 2 to 4 dS/m
sensitive no symptoms of salt-related stress develop with ECe of less than 2 dS/m
