“…Low rooting closely corresponds with the slowing down of growth and winter dormancy. These results are in complete agreement with the findings of previous studies on the relationship of rooting potential of stem cuttings to the morphophysiological status of the parent plant from which the cuttings are obtained (Harada and Nakayama 1957, Wareing and Smith 1963, Smith and Wareing 1972a,b, Vieitez and Pena 1968, Nanda and Anand 1970. The results, however, further show that while the high rooting phase from February till August is auxin sensitive (exogenously applied auxins promote rooting) the low rooting phase from September to January is not (exogenously applied auxins do not promote rooting).…”

Ficus infectoria stem cuttings were treated with 10 and 100 μg/ml each of IAA, IBA, 2,4, ‐D and NAA at monthly intervals and planted to study their rooting response after recording morphophysiological status and cambial activty of the parent branches. Attempts were also made to surgically expose the cambium before auxin treatment to determine the relationship of seasonal variation in auxin effectivity to cambial activity. The results show that: (1) there are two distinct phases in the sensitivity of Ficus infectoria stem cuttings to auxin‐induced rooting; (2) the high rooting phase coincides with renovation of growth and high cambial activity starting in March and lasting through August and the low rooting phase coincides with winter dormancy and low cambial activity; (3) roots emerge in longitudinal rows in slitted auxin‐treated cuttings; (4) slitted auxin‐treated cuttings root profusely in June when cambial activity is high but not in October when cambial activity is low suggesting a close correspondence of seasonal variation between the rooting activity of auxin and cambial activity.

“…The importance of vegetative buds in stimulating rooting of cuttings is well documented (4,9,17). Van Der Lek (10) observed that vegetative buds which stimulated rooting in summer and autumn, inhibited rooting in winter, with inhibition decreasing progressively in late winter.…”

Seasonal Changes in Auxin Effect on Rooting of Douglas‐Fir Stem Cuttings as Related to Bud Activity

The relation of seasonal bud activity to the periodicity of rooting in Douglas‐fir, Pseudotsuga menziesii (Mirb.) Franco, stem cuttings was studied in combination with auxin and cold storage treatments. Cuttings were collected in all months except April and May, for 3 years. Rooting was least in September and October when bud dormancy was most pronounced, greatest in December and January if exogenous auxin was applied, or in February and March if no auxin was used. The buds contributed significantly to rooting from January to April, and were responsible for differences in rooting of terminal and lateral cuttings during this period. Auxin did not enhance rooting in September and October, but at other times it replaced or supplemented the role of vegetative buds in promoting rooting. Auxin also removed the differences in rooting between lateral and terminal cuttings. Cold treatment in October and November removed bud dormancy and enhanced rooting. After November the need for auxin or cold treatment diminished and rooting without either treatment reached a maximum in February and March. Auxin did not change the seasonal pattern of rooting but broadened and enhanced the rooting response in favor of earliness. These results are discussed in relation to the effect of bud activity on auxin response and root initiation. The hypotheses are proposed that cambial dormancy or auxin deficiency is not the limiting factor during bud dormancy, and that cold treatments have the effect of bringing inhibitors and promoters into proper balance for optimum rooting response.
