Resumen:
In order to study biochemical changes and biomass accumulation of citrus genotypes
on salt stress. Were studied in a randomized block design, in factorial (2 x 5), two
salinity leveis (0.3 and 4.0 dS m'l) and ave citrus rootstocks genotypes ('Sunki'
mandarin [Citrus sunki(Hayata) hort ex Tanaka] common x citrange [C. sinensis (L.)
Osbeck x Poncirus trifo]iata (L) Raf] 'Argentina' - 019 (TSKC x CTARG - 019); Rough
lemon Florida (LRF) (Citrus jambhiri Lush)l tangerine 'Sunki' common x (Rangpur
time C. limonia Osbeck x P. trifoliata) - 040 [TSKC x (LCR x TR) - 040]] Rangpur
Santa Cruz (LCRSTC) (Citrus limonia Osbeck) and lemon Volkameriano (LVK) (C.
Volkamer V. Ten & Pasq), with three replications and four working plants 90 days
after sowing began the application of saline treatments that continued until 120 days
after sowing time the plants were evaluated for ace biochemical characteristics and
biomass accumulation of plants The TSKC x genotype (LCR x TR) -. 040, LCRSTC
and LVK were the least affected by salt stress highlighting how materiais more
tolerant to salinity. The LRF genotype did not influence the salinity in the synthesis of
pigments, but dramatically reduced the biomass accumulation, highlighting how
sensitive than the other genotypes. The TSKC genotype CTARG - 019 was the
material that had the photosynthetic pigments and biomass most affected by salt
stress, being among the materiais studied the most sensitive to salinity. Carotenoids
alleviate the effects of salt stress in citrus plants.
