Table 2.

The influence of foliage treated with 0, 0.4, 0.8, 1.2, 1.6, or 2.0 mM ethephon at 15 DAS on plant height, shoot fresh weight, root fresh weight, shoot dry weight, and root dry weight of Taipei-309 and Rasi cultivars of rice (Oryza sativa L.) at 30 DAS. Data are presented as treatment means ± SE (n = 4). Data followed by the same letter are not significantly different by the LSD test at p < 0.05. DAS, days after sowing.
