AU - Peet, M.M. T2 - Agricultural and Forest Meteorology AB - Data from six years of carbon dioxide (CO2) enrichment studies at North Carolina State University were analyzed in an attempt to develop predictive relationships for plant responses to different enrichment schemes and CO2 levels (600–5000 μl l−1). Cucumbers (Cucumis sativus L.) and tomatoes (Lycopersicon esculentum Mill.) were enriched using: (i) closed-loop cooling to extend enrichment periods beyond that generally practicable and (ii) elevated CO2 levels to compensate for short enrichment times normally encountered in conventional enrichment. Yields of nine cultivars of cucumber and seven of tomato, from both ground bed and bag culture, were regressed against solar energy, number of enrichment hours, fractional enrichment time, CO2 set point concentration (i.e., target concentration), and actual daily CO2 concentration. Absolute yields for cucumber were found to be strongly related to the solar energy received and, to a lesser degree, the number of enrichment hours. CO2 concentration, either set point or actual, was significant only when included in quadratic form. The relationship developed suggests that the optimum concentration is inversely related to the length of the enrichment period and that the product of the number of enrichment hours and the set point concentration should equal 14 400 μl h l−1. Absolute yields for tomato were also highly dependent upon solar energy, and to a lesser degree, either actual CO2 concentration, number of enrichment hours, or fractional enrichment time. Weight gain advantages for cucumber were found to be a linear function of fractional enrichment time (enrichment time divided by solar daylength), reaching a maximum value of 54% when continuously enriched during daylight hours. Weight gain advantages for tomato were found to be a non-linear function of fractional enrichment time with values of fractional enrichment time less than 0.5 producing little or no gain.

Days to germination (DTG) and percentage germination (PG) at 15 and 25°C after 2 and 20 weeks storage were calculated. No significant differences in PG could be detected among control seeds at 15°C 2 and 20 weeks after treatment. The DTG of control or chemically treated seed at 2 weeks was consistently lower than at 20 weeks, regardless of infusion medium. In contrast, the DTG was increased with storage. The PG of seeds treated with GA47 + ethephon was higher than that of all other treatments after 2 and 20 weeks of storage regardless of infusion medium. Moreover, the PG and DTG of seeds treated with GA47 and Progib were higher after acetone infusion. Seeds treated with Cytex, Cytozyme or Ergostim and infused with acetone did not germinate at either 15 or 25°C. The rate and total emergence of seedlings, sex expression, maturity date and fruit yield were not affected by seed treatment or infusion media when tested in field studies.

Concentrations of sucrose, raffinose saccharides, hexoses and starch, as well as activities of the sucrose metabolizing enzymes sucrose phosphate synthase (SPS) (EC 2.4.1.14), sucrose synthase (EC 2.4.1.13), and acid and neutral invertases (EC 3.2.1.26) were measured. Sucrose synthase and neutral invertase activities were relatively low (1.7 +/- 0.3 micromole per hour per gram fresh weight and 2.2 +/- 0.2, respectively) and changed little throughout fruit development. Acid invertase activity decreased during fruit development, (from as high as 40 micromoles per hour per gram fresh weight) in unripe fruit, to undetectable activity in mature, ripened fruits, while SPS activity in the fruit increased (from 7 micromoles per hour per gram fresh weight) to as high as 32 micromoles per hour per gram fresh weight. Genotypes which accumulated different amounts of sucrose had similar acid invertase activity but differed in SPS activity. Our results indicate that both acid invertase and SPS are determinants of sucrose accumulation in melon fruit. However, the decline in acid invertase appears to be a normal function of fruit maturation, and is not the primary factor which determines sucrose accumulation. Rather, the capacity for sucrose synthesis, reflected in the activity of SPS, appears to determine sucrose accumulation, which is an important component of fruit quality.

Radioactive phosphate was incorporated into the 120-kDa subunit of SPS during labeling of excised leaves with [32P]Pi, as shown by immunoprecipitation and denaturing gel electrophoresis of the enzyme. Conditions which activated the enzyme (illumination of leaves or mannose treatment of leaf discs in darkness) reduced the incorporation of radiolabel into SPS in the in vivo system. The partially purified SPS protein could also be phosphorylated in vitro using [γ-32P]ATP. In the in vitro system, the incorporation of radiolabel into the 120-kDa subunit of SPS was dependent on time and magnesium concentration, and was closely paralleled by inactivation of the enzyme. These results provide the first evidence to establish protein phosphorylation as a mechanism for the covalent regulation of SPS activity.

Similar maps to determine the southern limits of successful plant performance do not exist. Many northern species perform poorly when moved to southern climates and are generally better adapted to cooler areas or where rapid cooling occurs at night. Night (2000 to 0500 hours) temperature data from four physiographic areas of North Carolina were used to develop threshold temperature (5–30°C) curves for the months of May through October. These curves displayed a smooth, continuously differentiable, sigmoid shape between maximum and minimum asymptotes at 5 and 30°C. Fletcher (southern mountains) experienced the lowest night temperatures followed by Lewiston (northern Coastal Plain), Raleigh (central Piedmont) and Wilmington (southern Coastal Plain). Low/medium/high threshold temperatures of 15/20/25°C resulted in 261/64/0.5 and 278/256/64 threshold hours accumulated during July at Fletcher and Wilmington, respectively. A high threshold temperature of 25°C resulted in 1, 71, 65 and 133 threshold hours accumulated at Fletcher, Lewiston, Raleigh and Wilmington out of 828 total hours occurring during June, July and August. Threshold temperature curves were described mathematically using a five-parameter asymptotic model developed by van Genuchten. The mean threshold temperature exceeded by not more than 10% of the maximum threshold hours occurring during June, July and August was calculated for each station. These values and the threshold temperature curves were used to develop a hypothetical classification scheme for plant high night temperature tolerance zones.

Without migration, interpopulation variation and covariation depend mainly on the pattern and intensities of selection among populations and the harmonic mean of effective population sizes. Both transient and equilibrium covariance structures are formulated with suitable approximations. Migration reduces the differentiation among populations, but its effect is less with genotype-environment interaction. In some special cases of genotype-environment interaction, the equilibrium interpopulation variation and covariation is independent of migration.

High RH as well as high CO2 resulted in increased relative growth rate (RGR), increased dry weight of leaves, stems and roots, and increased leaf area on main and lateral stems during the first 2 weeks of growth. During this period, high CO2 levels interacted to stimulate the RH effects. During the third to sixth weeks of growth, the interaction of RH and CO2 was either lost or, as in the case of RGR and root dry weight, reversed in such a way that a negative effect of high CO2 at high RG was found. At 6 weeks there were positive main effects of RH and CO2, but no interaction on plant height, number of leaves on lateral shoots, number of lateral shoots, and length of lateral shoots. The shoot to root dry weight ratio increased at high RH. Water consumption of plants decreased sharply at high RH and moderately at the high CO2 level. Stomatal aperture was larger at high RH, but smaller at the high CO2 level. It is concluded that increased plant growth resulting from increased RH might be caused by an increase in stomatal aperture which in turn facilitates CO2 absorption and utilization.

The accumulation of RNA generated from this transcriptional fusion varied both temporally and spatially in all tissues examined in greenhouse-grown tobacco plants, suggesting that the CaMV 35S promoter is not constitutive. Younger, actively dividing leaf, stem, root, and flower tissues contained higher steady state levels of zein RNA than did older, more quiescent tissues. Zein RNA levels greatly decreased during seed development and were undetectable in the mature seed. In addition, the two RNA termination or processing signals present in our construct were differentially utilized during seed development.
