Figures & data
Table 1 Tiller numbers of the five ryegrass types counted on eight occasions over the first year from establishment of a closed sward. Values are means for five plants/type.
Fig. 1 Average fortnightly total root counts between November 1992 and November 1994 for five ryegrasses grown under well-watered and nitrogen-fed conditions in experimental root bins.
Fig. 2 Average fortnightly total root counts for 0–1.8, 1.8–3.5, 3.5–5.3 and 5.3–7.1 cm soil depths for five ryegrasses grown from November 1992 to November 1994 under well-watered and nitrogen-fed conditions in experimental root bins.
Fig. 3 Average fortnightly total root counts between December 1994 and December 1995 for five ryegrasses with no water applied for the first three months (A) and well-watered (B).
Fig. 4 Total root counts between December 1994 and December 1995 at 0–15, 15–25 and 25–60 cm depth for five ryegrasses with an initial 3 month drought treatment (A, B and C) or well-watered (D, E and F).
Fig. 5 Average vertical distribution of root counts for the five ryegrasses, as a percentage of total root counts, for well-watered treatments in 1993, 1994 and 1995, and the summer drought stressed treatment in 1995.
