Table 6.

Shoot (SL_DTI) and root (RL_DTI) length drought tolerance index of two wheat genotypes after 5 days of growth under drought treatments (15%, 20% and 30% PEG), combined (P-15% PEG, P-20% PEG and P-30% PEG) treatments, and high voltage electrical discharge (HVED) pre-treatment (P). Values are means of three repetitions (10 plants/repetition) ± S.D. The different capital letters indicate significances among means of different treatments within the same genotype, while lowercase letters indicate significances among means between genotypes under the same treatment at p < 0.05 using LSD post-hoc test.
