Grafting on salt tolerant eggplant rootstocks can be a promising approach for enhancing
the salinity tolerance of tomato. In this study, the performance of tomato cv. Kashi Aman grafted
on two salt tolerant eggplant rootstocks (IC-111056 and IC-354557) was evaluated against
non-grafted control under saline (ECiw 6 and 9 dS m−1) and non-saline (ECiw ~1 dS m−1) irrigation for
2 years. Grafting improved tomato plant performance under salt stress. Moreover, rootstock
IC-111056 outperformed IC-354557. An increase in the average fruit yield of grafted plants compared
with non-grafted control at 6 and 9 dS m−1 was 24.41% and 55.84%, respectively with rootstock
IC-111056 and 20.25% and 49.08%, respectively with IC-354557. Grafted plants maintained a
superior water status under saline irrigation, evidenced with the relative water content and chlorophyll
SPAD index, along with higher proline and antioxidant enzyme activities (superoxide
dismutase, catalase, and ascorbate peroxidase). Rootstocks mediated the partitioning of toxic saline
ions in the scions by promoting higher Na+ accumulation (14% of mean accumulation) in the older
leaves and lower (24%) in the younger leaves of grafted plants. This resulted in higher K+/Na+ ratios
within the younger (active) leaves of the grafted plants. Our study demonstrates that grafting tomato
seedlings on selected salt tolerant eggplant rootstocks is a viable alternative for improving
plant physiological status and fruit yield under salt stress, through favorable modulation of salt ion
partitioning in the scions.
