Saline stress onto growth and physiology of trifoliate citrus hybrids during rootstock formation

Cultivation of West Indian cherry irrigated with saline water under phosphorus and nitrogen proportions

“…As irrigation water salinity increased, rootstock and scion stem diameters were linearly reduced by 21.74 and 21.38% between plants grown under the highest (3.8 dS m -1 ) and lowest (0.6 dS m -1 ) levels of irrigation water salinity (Figures 1A and B). Reduction in the growth of fruit crops under salt stress conditions have also been observed by Brito et al (2017) and Bezerra et al (2018) in citrus rootstocks and guava plants, respectively. These authors attribute such reduction in plant growth to the increase of salinity in the root zone, through successive irrigations, which increase soil salinity.…”

Morphophysiology of Tahiti lime grafted onto Sunki mandarin hybrids under salt stress

“…Summary of variance analysis for rootstock stem diameter (SD-R), stem diameter measured at the grafting point (SD-GP), stem diameter measured in the scion (SD-S) and number of leaves (NL) after 30, 60, 90, 120, 150 e 180 days after the beginning of stress application (DABS) *, ** -Significant at p ≤ 0.05 and p ≤ 0.01 by F test; NS -Not significant; DF -Degrees of freedom; CV -Coefficient of variation Table 2. Summary of variance analysis for internal CO 2 concentration (CI), transpiration (E), stomatal conductance (gs), CO 2 assimilation rate (A), water use efficiency (WUE) and instant carboxylation 180 days after the beginning of stress application (DABS) stage and stress intensity (Silva et al, 2014;Barbosa et al, 2017;Brito et al, 2017). Syvertsen & Garcia-Sanchez (2014) report that temperature and rainfall conditions may intensify or mitigate salt stress on citrus.…”

“…Studies have reported genetic materials used as rootstocks with potential tolerance to salinity (Fernandes et al, 2011;Silva et al, 2014;Barbosa et al, 2017;Brito et al, 2008Brito et al, , 2016Brito et al, , 2017. Thus, the use of salinity-tolerant rootstocks can allow the use of water with high salt levels or even saline soils (Grieve et al, 2007;Prior et al, 2007;Brito et al, 2014Brito et al, , 2015.…”
