Abstract
Root hair production by young plants of lucerne, maize and perennial ryegrass grown in a sandy loam was assessed by examining roots growing at a soil-glass interface. Results are given for the percentage frequency distribution of root hair lengths and the numbers of root hairs produced per millimeter root. The mean lengths of root hairs observed on lucerne, maize and perennial ryegrass roots were 0.35, 0.90 and 1.12 mm, respectively. Lucerne produced an average of 105 root hairs/mm of root, whereas maize produced 161 and perennial ryegrass produced 88. The total length of root hairs per millimeter length of root was estimated to be 37, 146 and 99 mm for lucerne, maize and perennial ryegrass, respectively.
