Abstract
A USEFUL short paper by E. E. Kemp (J. Roy. Hort. Soc., 73, part 9, 291-305 ; Sept. 1948) gives some very practical information on the rooting of more difficult cuttings. The author draws on the practical experience of the Edinburgh Royal Botanic Garden to describe the important factor selection of material for this type of propagation. Descriptions of this are greatly helped by a series of very clear photographs. In the sections on preparation of cuttings for insertion and on rooting media, the writer interprets practically the physiological approach typified by Priestley and Swingle. Nodal cuttings are more generally satisfactory because of the absence of pith and the presence of additional meristem. The effect of environment on the healing of the cut wound and subsequent formation of callus and roots are also described on a physiological basis, which further indicates the chief desiderata of the rooting medium—air and water. It is indeed refreshing, in this era of hormonal rooting of cuttings, to find a good exposition of the blending of 'normal' physiology with practice for dealing with somejbf the difficulties of propagation.
