[...] They vary as to the colour of their leaves (from light-green to dark-metallic violet) the size and shape of the blade (narrow flat etc.) the form of its surface (smooth rough etc.) the colour of young shoots the length of internodes the ratio of the green to the brown part of a shoot the duration of the growing period (some forms begin their growth very early in spring and stop it late i [...] a. Young roots concentrate at the base of the shoot above the wired place.203 3. LAYERING The following types of layering were cested: (a) Simple mound layering (Plate 5). The leaves on the tower part of the shoot were removed and the earth mounded ound the bush in the usual way i.e. [...] These seven years' observations of the author have shown that the percentage of rooted plants depends upon the age of the shoots and the amount of moisture in the soil which surrounds them. [...] Shoots of the first type show a better power of orientation in the soil conditions and develop their roots in the proper direction while those of the second type waste their energy in producing a great quantity of roots all along the underground part of the shoot.211 Shoots of the first type may be obtained by every method of layering in case they are placed vertically from the base (the ringed
