Other claims from this paper (15)
- Observation The four grass materials had different regrowth patterns.
- Observation Primary growth was fastest at 21/16 and 24/19¦C.
- Observation Regrowth was fastest at 15/10¦C except in fescue.
- Observation Fescue regrowth was fastest at 24/19¦C.
- Intervention effect Four-week defoliation halved total dry matter yield.
- Intervention effect Frequent defoliation halved mean tiller and leaf number.
- Intervention effect Frequent defoliation reduced leaf area to a quarter of that under eight-week defoliation.
- Association Lower temperatures advanced reproductive development.
- Observation Reproductive development did not occur at 24/19 and 30/25¦C.
- Observation Italian ryegrass and prairie grass grew faster initially than tall fescue.
- Observation Yield and tiller number increased over successive regrowths with eight-week defoliation.
- Observation Tama Italian ryegrass maintained productivity under frequent defoliation.
- Mechanism Prairie grass productivity was limited by low tiller number despite high yield per tiller.
- Association Tama regrowth productivity was essentially independent of previous growth.
- Association Prairie grass regrowth depended strongly on previous regrowth.
