Effects of frost and frost protectants on tall fescue seed production

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 still showed some decrease in seed yield 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).

Other claims from this paper (11)

Intervention effect Insecticide application was only partially effective in controlling aphids.
Association Higher numbers of diamondback moth larvae were observed on mustard species than on canola species.
Observation S. alba was completely resistant to cabbage seedpod weevil and no damage by this pest was observed.
Observation Aphid colonization was observed on plants of all species.
Observation Aphid infestation on S. alba and B. rapa occurred too late to have a major effect on seed yield.
Intervention effect Seed oil content of canola species was significantly reduced by insect damage.
Intervention effect Oil quality, indicated by fatty acid profile, of canola species was not affected by insect attack.
Intervention effect Uncontrolled insect infestation reduced seed yield of B. napus by 37%.
Intervention effect Uncontrolled insect infestation reduced seed yield of B. rapa by 32%.
Intervention effect Yield reduction was least in S. alba, where untreated control plots lost on average less than 10% relative to insecticide-treated plants.
Recommendation The authors conclude that S. alba has good potential as an alternative crop for northern Idaho because it can be grown with reduced late season insecticide application.
