INTRODUCTION
It was in 1934 that the rootformlng activity of the plant
growth hormones, or auxins, was recognized. The continuing discovery of new substances wilh auxin activity, and the ready availability of many of these as synthetic products, led to very rapid
application of the principles to the large-scale handling of plants.
By 1936 a great many laboratories of plant physiology and horticulture were engaged in trials of the new compounds and within another
year a considerable volume of literature was appearing. There now
exists, therefore, more than ten years' accumulated experience on
the part of both pure and applied physiologists in'the rooting of
cuttings with auxins. 1
Much of thls experience is derived from routine trials in
many laboratories, greenhouses and experiment stations, which have
not been published. This is particularly true of recent years, since
the use of auxin preparations has become universal practice. A good
part of the data, however, has been published, though sometimes only
very briefly. Most of this refers to woody plants, that is, trees
and shrubs, and it is this body of results that has heen collected
in the present publication.
It was the authors' feeling that, before taking up again
research on vegetatlve reproduction of woody plants, it was essential to survey wh~t has been done. Accordingly an effort has been
made to collect all published data of a quantitative or semi-quantitative nature. These are sufficiently extensive so that work on
any new plant can be oriented within fairly narrow limits as to time,
concentration, season, etc. and probable resulls can be at least
rcughly predicted.
Two previous summaries have been made, by Pierce in 1939
and by Mitchell and Rice in 1942. The latter contains 89 references
while the present publication contains 291, i.e. some three times
as many. The increase is due partly to papers published since 1942
(to June 1947), and partly to the inclusion of many results published
in Europe and in the tropics which had not been previously covered.
IFootnote. For recent reviews of the entire field of auxins see:
J. van Overbeek, Ann. Rev. Biochem. Vol. 13 (1944); K. V. ThJ.mann,
A Treatise on Hormones, (ed. G. Pincus and K. V. Thimann) Chap. 2,
New York, the Academic Press, 191[.8.
1
OpportunIty has also been taken to include a number of unpublished
results from these laboratorIes. Data in this field are very widely
scattered, being published in Journals of agriculture, botany,
forestry, horticulture and plant physiology from allover the world,
as well as many special publications of limited circulation. For
this reason no claim is made for absolute completeness.
SOME
I~POnTA~T C(~TROLLI~G
FACTORS
As might be expected, very few new principles have been
elucidated by this work. There are four that are worth special
mention, however:-(a) Wounding by scraping down to the cambium at the base
of the cutting improves rooting markedly in many (but not all)
cases. The data on wounding have been Included in a special table
at the end of this publication.
(b) The age of the tree from which the cutting is taken
IS often a major factor, rooting ability decreasing rapidly with
increasing age. For this reason the ages of the stock material
have been included in the table wherever the original authors have
mentioned them. "here comparative results from the same species at
more than o~e age were reported these have also been included.
(c) Nutrition of the cuttings after auxin treatment is
probably of great importance, judging from the few studies so far
published, but it is too early to form a judgment as to the practical
value of this factor.
(d) Control of humidity, for leafy cuttings, has long been
recognized as important, but deserves much more quantitative study.
As yet no papers have been encountered in which different measured
humidi ties or spraying methods have been compared, though comparisons
have been published between arbitrarily selected humid and non-humid
conditions. Each laboratory has its own practice in this regard,
and it has not been possible to include data on the moisture relations of the cutting or the propagation bed in the table, because
the original papers are usually vague on such matters.
2
ME1HODS OF TREATMENT
In regard to the details of auxin treatment, little can be
added to the original statement of Went and Thimann (1937) that
11 the highest non- toxic concentration" usuall y gives the bes t rooting.
Where basal dipping in aqueous solutions is adopted the period of
exposure is usually 18 or 24 hOlII'S': Coating of the base of the
cutting with a mixture of the auxin and talc, indicated as "T" in
the treatment colu~l. of course involves no stated time of contact.
In general a simple mixture of the auxin and talc is indicated, but
in one instance (ref. 115) the data refer to a preparation in which
the auxin was intimately ground up with the talc; the optimum concentrations with this were frow 2 to 5 times lower ~han with a simple
mixture. In a few cases mixtures of the auxin with charcoal ("Ch."
in table) have been used, and the same mixture, or the talc, sometimes contains a fungicide, though few comparative results have been
published with such mixtures.
CCMPOUNDS USED
The auxins used have mainly been indole-3-acetic (IA), indole-3-butyric (IB) and naphthalene-I-acetic (~A) acids. Where
results with several concentrations of a given auxin are published,
we have selected the optimum concentration and mentioned the other
concentrations that were less effective. Often, however, the authors
merely report what they consider as the optimum concentration
("opt. cone." in table). Results with auxins other than the above
substances are listed under "other auxins", with name of the substance mentioned in the last column. Occasionally data have been
reported with commercial auxin preparations, whose nature and concentration are not stated; we have therefore included below a list of
these with approximate indications, culled from the literature, of
their composition. These are necessarily somewhat fragmentary.
ABBREVIATIONS
In the attempt to include as many critical data as can be
extracted from the papers, extensive use has been made of abbreviations, which may make the table seem at first somewhat cryptic.
However, in most instances these are the obvious abbreviations, and
in any event, they are fully explained in the lists below.

The species and variety,
literature reference,
type of cutting used,
month when taken,
treatment given the controls, i. e. whether untreated (U),
given plain water (time in hours mentioned), other plain
medium, or unspecified (C),
the percentage of controls which rooted (figures in parentheses are based on less than 10 cuttings; figures underlined once, on 10-49; and those underlined twice, on larger
numbers. Only these last can be considered signifjcant to
the second digit.),
the average number of roots per rooted control cutting,
concentration of indole-acetic acid in parts per million,
followed either by the duration of treatment in hours
("100;24" meaning 100 ppm. for 24 hours), by "dip" to indicate a basal dip of about 5 seconds in a concentrated
alcoholic auxin solution, or by "T", "Ch" or "L" when the
auxin is applied in a talc, charcoal or lanolin mixture
respecti vel y,
the percentage of indole-acetic acid treated cuttings which
rooted,
the average number of roots per rooted cutting (treated
with indole-acetic acid),
corresponding data for indole-butyric acid,
corresponding data for naphthalene-acetic acid,
corresponding data for "other auxins" (named ~n last
column) ,
number of days between treatment and recording the results,
additional comments on controls, on auxin treatment indicated, and on the effectiveness of other concentrations
and of other auxins,
notes on the material used, condltions of the experiment,
etc., and also names of the "other auxins" or of commercial
preparations containing the lA, IB, or NA respectively.
It is hoped that, with the aid of the above notes, the data
here compiled will. prove convenient for reference and a useful guide
for all engaged in vegetative propagation.
Grateful acknowledgment is made to the Maria ~Ioors Cabot
Foundation for its support not only of research in this field but
also of this publication.
