Abstract Lateral roots and root hairs are essential portions of cotton roots. However, the morphology lifespan ( Gossypium hirsutum L.) lateral in response to nitrogen stress have remained unknown. Two cultivars were assessed when no normal (138 mg N·kg −1 soil) added. The daily acquisitions phenotype information including angle, density, diameter, lifespan, hair length, obtained situ by a self‐designed platform RhizoPots equipped with high‐resolution scanners. Nitrogen starvation significantly reduced growth shoots roots, although there was less reduction than shoots. Root first organ respond deficiency through morphological changes. diameter angle as well decreased under stress. dramatically increased density length. Our results demonstrate that low can induce notable changes hairs, which may play crucial role adjustment uptake, particularly species adapt availability.
