- Abstract
Arid and semiarid regions are vulnerable to water deficits and salinity. Citrus plants are sensitive to saline stress and require the use of tolerant scion-rootstock combinations. Thus, this study aimed to evaluate and classify citrus scion-rootstock combinations with respect to their tolerance to salinity during seedling formation in a protected environment. An experiment was conducted in a randomized block design with a 5 x 12 x 2 factorial scheme corresponding to five levels of water salinity (0.8, 1.6, 2.4, 3.2, and 4.0 dS m-1) applied in 12 citrus rootstocks grafted with two scion varieties: 'Tahiti' acid lime and 'Star Ruby' grapefruit. The scion-rootstock combinations were evaluated for accumulated dry matter and survival index at 330 days after sowing the rootstocks. Salinity exerted different effects on the dry matter formation of scion-rootstock combinations. 'Star Ruby' was less sensitive to salinity, particularly when the rootstocks were the hybrids from 'Sunki of Florida' mandarin (TSKFL) with 'Troyer' citrange (CTTR) -- 013 (TSKFL x CTTR -- 013), common 'Sunki' mandarin (TSKC) with 'Argentina' citrange (CTARG) -- 019 (TSKC x CTARG -- 019), TSKC with 'Swingle' citrumelo (CTSW) -- 031 (TSKC x CTSW -- 031), and the trifoliate hybrid (HTR) - 069, as well as the varieties Volkamer lemon and Santa Cruz Rangpur lime. When grafted with 'Tahiti' acid lime, the rootstocks displaying the less sensitive to salinity were TSKFL x CTTR - 013 and TSKC x CTARG - 019.
