Table 1 Effect of ferulic acid treatment on number and length of crown root, lateral root and root hairs in rice

From: Autotoxicity mechanism of Oryza sativa: transcriptome response in rice roots exposed to ferulic acid

Character a Water 50 ppm FA
Crown root number 6.93 ± 0.88 2.93 ± 0.70
Lateral root number/seedling 20.73 ± 2.63 6.67 ± 1.54
Lateral root length (mm) 6.15 ± 0.93 2.45 ± 0.60
Root hair number/mmb 73.5 ± 6.50 40.1 ± 3.07
Root hair length (μm) c 599.05 ± 30.34 205.55 ± 27.29
  1. a Number and length of root hairs on seminal root measured after 24 h FA treatment; other characters were determined on seedlings after 3-day FA treatment. Data are mean ± SD.
  2. b Number of root hairs from one side of 1-mm sections at the root hair zone (3–4 mm behind the root tip) on seminal roots. Data are mean of 10 seedlings.
  3. c Length of the 20 longest root hairs from the root hair zone of each seminal root. Data represent the mean of 10 seedlings.
