THE USE OF AUXINS IN FORESTRY


The author, Professor of Botany at the Faculty of Natural Science.
University of Zagreb and Secretary of the Department of Natural Sciences
of the Yugoslav Academy of Science and Arts, gives here a short review
on the book entitled »Express forests« by D. A f a n a s i j e v, published
1952 in Sarajevo in the Serbo-Croatian language. Eng. A fa n a s i-
j e v shows in his book the results of his experimental investigations at
the Experimental Station in Sarajevo, made during the years 1937—1941.
According to them he suggests the idea of breeding »express growing
forests«, which could be attained by the use of agro technical methods in
several years, but for which several decennaries have been needed by the
use of present methods in forestry. Eng. Afanasije v gives the most
particular importance, besides the fertilization with various fertizars, to
»the auxins«, and considers »the explorations and the amelioration of
auxins« as the chief task of forestry. At this occasion, the author is demonstrating
the use of auxins in agriculture, horticulture and forestry,
and is analysing — from this point of view — the explanation of Eng.
Afanasijev.


The author points out in his analysis, that Eng. Afanasijev has been
using in his experiments — for which there were prepared experimental
methods — various mixtures of heterogeneous manures with some addition
of Mangane and Borax as trace elements, as well as an admixture of
brown coal and even aspirin. There are not given any statements about
these mixtures and even Eng. Afanasijev himself confesses that »the
explorations of auxins are made as the ancient alchemists hap-hazardly
were doing«, and even that by this method »it is not determined which
elements of the utilized mixtures has produced fast growth«. The author
in his review calls attention to the inexactness of the methods of Eng.
Afanasijev.


On the other hand, the author calls attention on the inaccuracy of
Eng. Afanasijev for having applied already a well known and determined
definition of »auxin« in the science. Eng. Afanasijev considers »trace
elements« as true auxins what does not correspond to the present state
of science. The author gives a short and summerized review or system
of biocatalysators by Schopfe r as information to forestry experts
and calls attention to the general literature on auxins (Boysen-Jen sen,
Otte, Schlenker, Went, Thimann, Cholodny, Skoog,
etc.) not being stated by Eng. Afanasijev in his book. The author points
to the application of brown coal by the experiments of Afanasijev, which
as well is not exactly accomplished, and without the knowledge of the
scientific literature.
