Developmental characteristics of grass varieties in relation to their herbage production part 3 tiller development in dactylis glomerata and lolium perenne in relation to head emergence



Developmental characteristics of grass varieties in relation to their herbage production part 3 tiller development in dactylis glomerata and lolium perenne in relation to head emergence



Journal of Agricultural Science 91(1): 117-130



Features of the gross morphology of primary growth of D. glomerata 'S.345' and L. perenne 'S.24' and associated changes in digestibility are described. Species differences were noted with regard to the relationships between head emergence and the time when stem apices were raised to defoliation height, vegetative reproductive tiller ratios and tiller size. Also there were differences in the sequence of extension growth of leaf sheaths, internodes and inflorescence leading to emergence of the head. Associated changes in the vertical distribution of leaf blades were examined. In perennial ryegrass extension growth of the inflorescence continued after emergence had begun, but not in cocksfoot. Weight increments in the inflorescence, from emergence onward, followed the same pattern in the 2 spp., however. Differences in the developmental patterns of the 2 grasses apparently did not influence their relative digestibility. Upper internodes of reproductive tillers of 'S.24' ryegrass declined repidly in digestibility. Species differences, and the pattern of changes in the digestibility of lower and upper parts of reproductive tillers, are discussed in relation to mechanical aspects of sward development and micro-environmental effects.
