Resumo:
In order to study the emergence, growth and biomass accumulation of coriander
cultivars under salt stress. The experiment was conducted in a protected
environment (greenhouse) of the Center for Science and Technology Agrifood -
CCTA Federal University of Campina Grande - UFCG, located in the municipality of
Pombal, PB, from August to September 2014. Were studied two coriander cultivars
(CI - Verdão SF 177 and C2 Portuguese Pacific) and ave leveis of irrigation water
salinity (0.6 (contro1), 1 .2, 1 .8, 2.4 and 3.0 dS m'l), arranged in a factorial scheme 2 x
5, under a randomized complete block design with four replications and ave plants
per repetition. Coriander plants were grown in trays of 36 ballots with capacity of 0.1
dm3 substrate, unti1 20 days after sowing, in this period the plants were evaluated for
the emergente, growth. biomass accumulation and tolerance salinity. Increased
salinity gives irrigation water reduced the percentage of emergence, growth and
biomass accumulation of coriander plant. Cultivar Portuguese Pacific is more tolerant
to salinity that cultivate Verdão SF 177. The Portuguese Pacific cultivars and Verdão
SF 177 can be irrigated with water up to 2.6 and 1 .9 dS m'l, respectively, in the initial
phase of growth.
