    Notes: [Auszug] Accordingly, there is need of a satisfactory and more widely applicable method, for grasses which are grown in the field, to distinguish functional or non-functional parts of the root system. We applied carbon-14 to the leaves of seedlings of Italian ryegrass (Lolium multiflorum Lam.) and traced ...

    Notes: The root growth of 3 temperate–region grasses (perennial ryegrass, Italian ryegrass, and cocksfoot) and of 3 tropical grasses (Dallis grass, Bahia grass, and Rhodes grass) was investigated in large glass–sided root–boxes. The trend of root numbers and the rate of elongation of roots were ascertained to discover how the Japanese climate affected the root growth of these species.All the temperate–region grasses produced new roots vigorously during spring, but root growth ceased in August, whereas the roots of tropical grasses grew rapidly in this month. The alternate use of these two types of grasses during the growing season may therefore be worthwhile in Japan

    Notes: Absorption by the tap-root and by different nodal roots of white clover S100 and translocation of 32P were investigated to find to what extent nodal roots can compensate for the absence of a tap-root. 32P absorbed from the tap-root was distributed evenly within the whole plant. When translocation from the 2nd and 7th nodal roots was studied, similar distribution was obtained only from the nodal root closer to the centre of the plant. The backward movement of 32P absorbed from nodal roots at the base of the plant increased as the root size increased. Removal of tap-roots resulted in temporary depression of translocation; its effect disappeared within 3 weeks.It is concluded that the ability of nodal roots to compensate for loss of the tap-root depends on their position and size.
