Other claims from this paper (5)

Intervention effect PRG ploidy had no effect on herbage DM production, white clover content or tissue turnover over winter (P > 0.05).
Intervention effect White clover inclusion caused a significant decrease in herbage DM production over winter, of 254 kg DM/ha.
Intervention effect Stolon mass was not affected by PRG ploidy (P > 0.05).
Intervention effect Stolon length and number of leaves per stolon were affected by PRG ploidy (P < 0.05).
Intervention effect Including white clover in PRG swards can alter winter sward dynamics, potentially causing difficulties in spring management through reduced over-winter growth rate compared with PRG.
