Abstract
Abstract Root samples were obtained from 9-year-old trees of 3 citrus scions propagated on ‘Milam’ (a possible Citrus jambhiri Lush, hybrid) cuttings and seedlings. The root distribution and root density of trees on cuttings compared favorably with that of trees on seedlings, the usual commercial method of rootstock propagation. Significant factors affecting their respective root systems were method of propagation, scion, and soil depth; one interaction, propagation × depth, was significant. Trees on cuttings had a significantly larger total feeder root weight and surface root density than trees on seedlings.
