Abstract/Contents:"To model variations in leaf/stem ratio in connection with studies of field-drying of grass, account was taken of the effects that the stage of morphological development of grass has on the allocation of biomass to plant components, as well as on duration of growth and peak yield. A comparison of experimental data and corresponding daily weather data suggested that it is more satisfactory to express the stages of grass development in terms of degree-days than time alone. On the basis of one set of weekly measured data, the ratio of green leaf weight to above-ground biomass was found to be a close fit to a positive linear relationship early in the growth period (during expansion of the first leaf on each tiller), followed by negative exponential relationship (during expansion of subsequent leaves), in relation to relative development expressed as growing degree-days. Similar trends, but with some quite large variations in absolute values because of unknown factors, were found in two other datasets consisting of a few measurements only."
