Abstract:
In order of evaluate the growth of citrus genotypes (varieties and hybrid) under salinity, in the
formation phase, an experiment was accomplished in randomized blocks, with three repetitions, in
greenhouse. Five levels of irrigation water salinity were studied, combined to twelve citrus genotypes
rootstochs in two varieties cups. Nine plants compos the experimental unit, in pots of polyethylene of
288 mL by five months after the sow, when they were transplanted for pots of plastic, using
commercial substratum. The saline waters applications initiated at 60 days after the to sow, and
extending until the dumb ones be capable to the transplant in field. Every 30 days from the beginning
of the treatments to the enxertia, it was obtained the plant height, the stem diameter and leaf number
of the portaenxertos; after the graft, the graft leaf number, length of the graft and graft diameter were
obtained. The data were submitted the variance analysis by the Test 'F', and performing for the
quantitative factors the regression analysis and for the qualitative ones averages tests (p<0,05).
Ending that: The salinity reduces the citrus growth; the TSKFL X CTC25 - 010 and Citrangeiro Troyer
have larger growth before the enxertia; The rangpour lemon with Tahiti combination is the most
indicated.
