Other claims from this paper (8)

Intervention effect In wet silt loam, the number of cysts increased significantly with time.
Intervention effect In dry silt loam, the number of cysts stayed the same as the initial infestation.
Intervention effect In both wet and dry clay, the number of cysts declined significantly in all years of the study.
Intervention effect SCN infestation caused a reduction in soybean seed yields in both soils compared with noninfested controls.
Association Soil water content interacted with the level of SCN infestation to influence soybean yield.
Association Yield declines associated with SCN infestation were highly correlated with the number of seeds.
Observation SCN did not maintain populations in clay soil under greenhouse conditions.
Observation SCN did not produce the magnitude of yield decline typical of coarse-textured soil.

Other claims from this paper (11)

Intervention effect Four cycles of early flowering selection gave 0.8 d less flowering.
Intervention effect Four cycles of early flowering selection gave 10 g kg ‐1 less grain moisture.
Intervention effect Four cycles of early flowering selection gave 4.0 cm less plant height.
Intervention effect Four cycles of early flowering selection gave 2.7 cm less ear height.
Intervention effect Four cycles of early flowering selection gave 0.2 d less silk delay.
Intervention effect Four cycles of early flowering selection gave 0.15 Mg ha‐1 (3%) less yield.
Intervention effect Four cycles of early flowering selection gave 4% more broken stalks.
Mechanism Reduced plant size probably reduced photosynthetic capacity.
Association Later flowering synthetics respond more to early flowering selection than earlier flowering synthetics.
Association Longer, cooler days at flowering in shorter season areas favor early flowering selection.
Recommendation Early flowering selection can help move diverse germplasm into shorter season growing areas.

Other claims from this paper (5)

Observation Glycerinated cowpea hypocotyl cylinders had a definite cell wall yield threshold.
Intervention effect Acidification to pH 4 reversibly decreased the cell wall yield threshold.
Intervention effect Heat treatment completely inhibited the acidification-induced decrease in yield threshold.
Intervention effect Heat treatment significantly, but incompletely, inhibited the acidification-induced increase in cell wall extensibility.
Mechanism The authors infer that a wall-binding protein enzyme mediates the acid-induced fall in yield threshold.

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).
