Title:The effect of tiller shading on growth of several grasses

Abstract/Contents:The relationship between growth of the main shoot and that of its tillers was investigated in (a) tall fescue, (b) cocksfoot, (c) timothy, (d) tall oatgrass, (e) Italian ryegrass and (f) perennial ryegrass. One primary tiller of each plant was shaded with black cheesecloth and the remaining tillers removed. In all species there was a marked reduction in increase of DM, leaf area and secondary tillers in the shaded tiller regardless of leaf age. The reduction was greatest in the order (a))(b))(c))(d))(e))(f). In (a), tiller shading reduced the dry weight, leaf area and number of tillers on the main shoot, but not in (e) or (f). The ratio of the dry weight of the shaded tiller:total top dry weight decreased in all species compared with that for an unshaded tiller in control plants; the ratio was lowest in (a) followed by (b), (c), (d), (e) and (f). It therefore appeared that in some species the growth of tillers and the main stem was seriously affected by tiller shading, but in others the effects were relatively slight. F.en s.
