Summary
The total fibrous-root length of mature field-grown lettuces, which were protected from rainfall and not irrigated after establishment was less than 75 per cent of that of irrigated plants, although the corresponding root weights were very similar. Non-irrigated plants had thicker roots, less roots near the soil surface, and more at depth. Up to the time that the roots started to die, about two weeks before the lettuce were mature, the variation of root length with depth and time is described by a simple logarithmic expression. re]19730803
