Salinity Ratings codes

Salinity Ratings refer to the level of salt tolerance: M = moderate; T = tolerant; S = sensitive; MS = moderately sensitive; MT = moderately tolerant

Notes:

(a) These data are applicable when rootstocks are used that do not accumulate Na+ or Cl- rapidly or when these ions do not predominate in the soil.
(b) Botanical and common names follow the convention of Hortus Third (Liberty Hyde Bailey Hortorium Staff, 1976) where possible.
(c) In gypsiferous soils, plants will tolerate ECe about 2 dS/m higher than indicated.
(d) Ratings with a * are estimates.
(e) Tolerance is based on growth rather than yield.
