Title

Effect of Abscisic Acid Treatment on psbA Gene Expression in Two Wheat Cultivars during Grain Filling Stage under Drought Stress

Yue Wang ACTA AGRONOMICA SINICA 2011

Other claims from this paper (10)

Intervention effect PEG drought stress decreased relative water contents, chlorophyll contents and yield of wheat.
Intervention effect PEG exposure caused transcriptional inhibition of the psbA gene in wheat.
Intervention effect Exogenous ABA significantly alleviated drought stress injury in wheat.
Intervention effect Exogenous ABA restored all measured parameters of wheat to control levels under drought.
Association Shaanmai 5 had less destroyed plasma membranes than Yumai 949 under drought.
Association Shaanmai 5 showed smaller reductions in RWC, chlorophyll contents and yield than Yumai 949 under drought.
Association Shaanmai 5 showed a smaller reduction in psbA transcriptional level than Yumai 949 under drought.
Association Cultivar-dependent drought stress resistance of wheat is correlated with psbA gene expression.
Mechanism Exogenous ABA may enhance wheat stress resistance at grain filling by protecting PSII gene transcription.
Mechanism Exogenous ABA has a regulatory function on psbA expression in wheat.

Title

Vetch-wheat crops are superior to vetch-oat crops in terms of protein yield

R. Lauk; E. Lauk; E. Lauringson; et al. Acta Agriculturae Scandinavica Section B - Soil & Plant Science 2006. doi:10.1080/09064710600684854

Other claims from this paper (18)

Intervention effect Adding vetch seed to cereal seed, and raising vetch seed density, considerably decreased the yield of the cereal component.
Intervention effect Vetch reduced wheat yield by up to 1861 kg ha−1 on average over three years.
Intervention effect Vetch reduced oats yield by up to 1413 kg ha−1 on average over three years.
Intervention effect Wheat 1000-seed weight decreased by up to 6.3 g with increased vetch seed density.
Mechanism The decreases in cereal yields are explained by the formation of smaller grains under increased vetch seed density.
Intervention effect Adding vetch and raising its seed density substantially increased the protein content of cereal grains.
Intervention effect In oats, the change in grain protein content with vetch was smaller than in wheat.
Intervention effect The maximum protein yield per area of cereals was obtained from monocultures.
Intervention effect In a mix with vetch, the nitrogen consumed by cereals decreased.
Intervention effect Protein yield of cereals per area unit was reduced at higher vetch seed densities.
Intervention effect Vetch-cereal mixes had an advantage over cereal monocultures for protein yield.
Intervention effect The maximum protein yield in vetch-wheat mixes was 500 kg ha−1 on average over three years.
Intervention effect The maximum protein yield in vetch-oats mixes was 438 kg ha−1 on average over three years.
Intervention effect The vetch-oats mixed crop gave the highest grain yield of the two combinations.
Mechanism The higher mixed crop yield of vetch-oats resulted from the oats component.
Observation Oats is somewhat more competitive with vetch than wheat.
Mechanism Vetch-wheat mixed crop gave the highest protein yield because wheat grain protein content was higher than oat grain.
Recommendation Legume-cereal mixes are suited to organic farming conditions.
