Seed Halopriming Improves Salinity Tolerance of Some Rice Cultivars During Seedling Stage

Botanical Studies

Table 4 Seed priming greatly increased salinity tolerance of IR 64 seedlings, as measured by SES score 7 days after salinity stress

Cultivar	Seed priming treatment	SES score	Level of salinity tolerance
Pokkali	Unprimed	2.6 ± 0.84	Tolerant
	Primed	2.4 ± 0.97	Tolerant
CI Pendek	Unprimed	3.4 ± 0.84	Tolerant
	Primed	3.8 ± 1.03	Tolerant
Merah Kalsel	Unprimed	4.6 ± 0.84	Moderately tolerant
	Primed	3.6 ± 0.97	Tolerant
IR 64	Unprimed	8.4 ± 0.97	Highly sensitive
	Primed	3.6 ± 0.97	Tolerant

The Standard Evaluation System (SES) for rice was used to assess visual salt damage in seedlings at 7 days after salinization (200 mM NaCl). SESscores: 1 (highly tolerant), 3 (tolerant), 5 (moderately tolerant), 7 (sensitive) and 9 (highly sensitive). Values are the means of ten seedlings ± SE
