The physiology of plagiotropic growth of rooted cuttings of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco]

Creator:

Starbuck, Christopher J.

Abstract:

Experiments were conducted to determine if the plagiotropic growth habit of rooted cuttings of Douglas-fir might result from a system favoring the accumulation of indoleacetic acid in the adaxial side of the shoot in response to vertical placement. Actively growing excised branch terminals were subjected to gravitational disorientation to determine...

Root initiation and elongation in Douglas-fir, Pseudotsuga menziesii (Mirb.) franco, stem cuttings as related to bud and cambial activity

Creator:

Bhella, Harbans Singh

Abstract:

The relation of bud and cambial activity to root initiation and elongation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stem cuttings was studied through two successive growth cycles. Stem cuttings of current season's growth were taken periodically from field-grown Douglas-fir trees to determine: (1) origin and development of root initials; and...
