Low pH condition induced root hair formation in lettuce seedlings. Hair formation initiated in a 1.5-2.5 mm portion from a root tip 4 hr after the medium pH changed from pH 6 to pH 4 and became saturation 7 hr after. Over 80°/0 of the rhizodermal cells formed hairs at saturation. The longitudinal length of the rhizodermal cells located in the abovedescribed portion gradually decreased after the pH change, and the value became about a half of the initial size after 8 hr. Root hairs were formed… CONTINUE READING
