M. D. Hare New Zealand Journal of Agricultural Research 1993. doi:10.1080/00288233.1993.10417740

Other claims from this paper (9)

Observation Tall fescue reproductive tillers are particularly sensitive to frost damage at ear emergence and during anthesis.
Intervention effect A -5 C air frost destroyed all seed heads of tall fescue.
Intervention effect A single exposure to -2 C frost reduced tall fescue seed yield by nearly 50%.
Intervention effect The -2 C frost had relatively less effect on tall fescue seed weight and germination, provided frost did not occur at ear emergence or anthesis.
Intervention effect Developing tall fescue seed 6 and 8 days old was less susceptible to -2 C frost.
Intervention effect Developing tall fescue seed 6 and 8 days old showed a slight reduction in the rate of germination after -2 C frost.
Intervention effect The two frost protectants (Teric and Kocide 101) did not prevent frost damage from occurring in tall fescue.
Intervention effect After -2 C frost the seed yield reduction was less in tall fescue seed heads protected by Kocide 101 than in untreated seed heads (P < 0.05).
Intervention effect After -2 C frost the seed yield reduction was less in tall fescue seed heads protected by Teric than in untreated seed heads (P < 0.10).
