In our experimental format, all three cultivars are susceptible to P. capsici. ‘New Yorker’ seeds were obtained from a commercial source . The homozygous ABA-deficient mutants sitiens and flacca were compared with their isogenic, wild-type background, ‘Rheinlands Ruhm,’ and seeds for these were obtained from the C. M. Rick Tomato Genetics Resource Center, University of…

The biomass increase of the plants without external N was most likely supported by the pool of internal N in the plant. At the time the external N supply was removed, the N content in the plants was above their CNC. The critical nitrogen content of a tissue is defined as the lowest amount of…

Economists have found that the initial filing of a case often disrupts imports, irrespective of the final legal determination. The AD statute comes under Section 731 of the U.S. Tariff Act of 1930 , as amended. A related statute is Section 701, which applies to subsidized exports from foreign suppliers. Under Section 701, if a…

The TSCF accounts for the reduction in concentration in the pore water as it crosses the root membrane and moves through the xylem to the stem. Thus, the TSCF represents the ratio of contaminant concentration in the xylem stream of the stem, mg/L, to contaminant concentration in soil solution, mg/L. Hsu et al. and Burken…

The funnel was placed in the centrifuge tube and incubated in the 65Zn solution for 60 min, with the fluid level coming to the full level of the funnel spout to fully immerse the roots. To avoid generating a large amount of radioactive waste all plants were incubated in the same tube. For the first…

In addition, investigation of monovalent cation selectivity of OsHKT1;4 expressed in oocytes bathed in solutions containing solo cation-chloride salts further revealed that this transporter is highly selective for Na+ amongst Li+ , K+ , Rb+ , Cs+ , Na+ , and NH4 + . These results indicate that OsHKT1;4 is a Na+ transporter. HKT proteins…

As mentioned earlier, short-term increases in yield should appear directly in the GDP accounts if land under cultivation is relatively fixed in the short term, and agricultural output constitutes a sizable share of GDP. Table 5 presents fixed effects OLS estimators for equation , covering five-year growth periods from 1965 to 2000. Consistent with the…

The expansion of large-scale commercial agriculture has also caused deforestation of some of the most bio-diverse forests in the world, such as in the Amazon, for soybean production , and in Southeast Asian rain forests, for oil palm . Since the 1990s, particularly in Brazil and Indonesia where the greatest amount of deforestation occurred, the…

Such information can be used to derive inputs for crop models in conjunction with yield mapping analysis to identify areas in the field that are stable over space and time. Crop models can be executed on those areas to provide insights on the reason of variability as well as estimates of potential economic return of variable-rate…

While smallholders are not bound to PAD’s recommendations, PAD promises higher yields and profits, holds a monopoly on knowledge, and is using its knowledge to ensure obedience. This external control, a dynamic of urbanized agrarian knowledge, is problematic in its own right: while often very specific about climate and soil conditions, PAD appears to take little heed of local social,…
