Influence of Japanese Brome on Western Wheatgrass Yield

Marshall R. Haferkamp; R. K. Heitschmidt; Michael G. Karl Journal of Range Management 1997. doi:10.2307/4002704

Other claims from this paper (6)

Intervention effect Removal of Japanese brome reduced total standing crop by 500 kg ha-1 in the western wheatgrass community.
Intervention effect Removal of Japanese brome increased standing crop of western wheatgrass by 220 kg ha-2.
Intervention effect Removal of Japanese brome increased tiller density of western wheatgrass by 153 tillers m-2.
Mechanism The increase in western wheatgrass standing crop appeared to result from increased tiller density rather than increased weight per tiller.
Intervention effect Western wheatgrass water relations were essentially unaffected by removal of Japanese brome in 1992.
Recommendation Removal of Japanese brome may increase production of associated perennial grasses.

Observation Clover lost between 60% and 95% of lamina weight, especially from leaves.
Intervention effect The change from autumn to winter caused a greater decrease in the number of live leaves per shoot in clover than in grass.
Intervention effect The change from autumn to winter caused a greater decrease in the area and weight of individual leaves in clover than in grass.

Extension rate and respiratory activity in the growth zone of wheat roots: Time‐course for adjustments after defoliation

I. J. Bingham; A. Panico; E. A. Stevenson Physiologia Plantarum 1996. doi:10.1111/j.1399-3054.1996.tb00693.x

Other claims from this paper (11)

Intervention effect Leaf pruning reduced the extension rate of wheat seminal and lateral roots
Intervention effect Onset of the response to pruning occurred within 1 h in lateral roots
Intervention effect Onset of the response to pruning occurred between 2 and 3 h in seminal roots
Association In seminal roots, the reduction in extension rate was preceded by a decrease in soluble sugar content of the apical growth zone
Intervention effect Supplying glucose to defoliated wheat roots led to a steady increase in extension rate compared with non-fed controls
Intervention effect Supplying 3-O-methyl glucose had no effect on wheat root extension
Association The reduction in extension rate of seminal roots was accompanied or slightly preceded by a reduction in respiratory O2 uptake in the apical growth zone
Observation Changes in respiratory activity in the basal growth zone only occurred several hours after extension rate was reduced
Intervention effect At the time extension rate was reduced, the rate of O2 uptake of wheat roots could be stimulated with FCCP
Mechanism Respiration in wheat roots is suggested to be under the fine control of adenylates
Intervention effect Defoliation caused a rapid reduction in respiratory capacity in the root apex before any change in overall respiration

Other claims from this paper (12)

Intervention effect High EC significantly reduced yield in greenhouse tomato relative to 2 dS/m.
Intervention effect Low transpiration mitigated the effect of high EC on tomato yield relative to high transpiration.
Intervention effect Under high EC, high transpiration reduced marketable tomato yield by 30 percent relative to low transpiration.
Intervention effect Under high EC, high transpiration gave tomato fruits about 25 percent smaller than low transpiration.
Intervention effect Under high EC, high transpiration increased blossom-end rot incidence to 20 percent relative to low transpiration.
Intervention effect Low transpiration with high EC reduced tomato size and yield by 15 percent relative to 2 dS/m.
Observation Under low transpiration, incidence of blossom-end rot was only 2 percent.
Intervention effect Dry matter and sugar content of tomato fruit were higher under high EC than under 2 dS/m.
Observation Total dry matter yield of tomato was the same across treatments except the high EC, high transpiration treatment.
Observation In the high EC, high transpiration treatment, blossom-end rot reduced marketable tomato dry matter by 25 percent.
Observation Tomato fruit elasticity was not affected by any treatment once size differences were accounted for.
Recommendation Appropriate use of indoor climate tools can offset the effect of high salinity of irrigation water on tomato.

Intervention effect In barley, the 2:1 treatment increased the variation in net benefits by 18%.
Intervention effect Water-harvesting in valley floors is not a net yield-increasing technology for cereals.
Intervention effect In wheat, the 1:1 treatment reduced the coefficient of variation by 19%.
Intervention effect In wheat, the 2:1 treatment reduced the variation in net benefits by 8%.
