    Notes: ‘Georgia-Jet’ sweet potatoes were grown at CO2 concentrations of 354, 431, 506, and 659 ppm for 90 days. Elevated CO2 concentrations decreased protein, total carotenoids and insoluble dietary fiber. An increase in dry matter and a reddish-orange color was observed at 506 and 659 ppm CO2 concentrations. Sensory evaluation scores for flavor and moistness indicated that sweet potatoes grown under high CO2 concentrations were acceptable and not different from the control.

    Interaction of enriched CO2 and water stress on the physiology of and biomass production in sweet potato grown in open-top chambers (1990)

    Notes: Abstract. The objective of this study was to investigate the effects of water stress in sweet potato (Ipomoea batatas L. [Lam] ‘Georgia Jet’) on biomass production and plant-water relationships in an enriched CO2 atmosphere. Plants were grown in pots containing sandy loam soil (Typic Paleudult) at two concentrations of elevated CO2 and two water regimes in open-top field chambers. During the first 12 d of water stress, leaf xylem potentials were higher in plants grown in a CO2 concentration of 438 and 666 μmol mol−1 than in plants grown at 364 μmol mol−1. The 364 μmol mol−1 CO2 grown plants had to be rewatered 2 d earlier than the high CO2-grown plants in response to water stress. For plants grown under water stress, the yield of storage roots and root: shoot ratio were greater at high CO2 than at 364 μmol mol−1; the increase, however, was not linear with increasing CO2 concentrations. In well-watered plants, biomass production and storage root yield increased at elevated CO2, and these were greater as compared to water-stressed plants grown at the same CO2 concentration.

    Herbicidal Effects on Water Uptake of Seeds of Selected Weed Species (1970)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 23 (1970), S. 0

    Topics: Biology
    Notes: Seeds of yellow foxtail, johnsongrass, pigweed and quackgrass were investigated to determine the effects of certain herbicides on water uptake by these species. Seeds of johnsongrass showed slight increase in water uptake over the 20-h period when treated with 1, 5, 10, and 500 mg/1 of 2,4-D. Tordon caused a most pronounced increase in water uptake at 0.1 and 1 mg/l as compared with the controls. Johnsongrass gave indications of either increases or decreases in water uptake when treated with herbicides during the 20-h period, but showed no effects during the 10-h period. Dormant seeds of yellow foxtail indicated an enhancement in water uptake at all 2,4-D concentrations during the 20 h period. The effects which the different herbicides had upon the uptake of water in yellow foxtail seeds seemed to be directly proportional to increase in imbibition time. In all cases, more water was imbibed after 20 h over that observed at 10 h. During the 10-h imbibition period, pigweed seeds treated with 2,4-D was noted to have a slight stimulating effect on water uptake at all concentrations employed except 5 mg/l, which indicated a depressing effect. It was also observed that 2,4-D caused a significant stimulating effect on water uptake of pigweed seeds over the 20-h period as compared with the controls. A stimulation in the total quantity of water imbibed after 20 h was noted at dacthal concentrations below 100 mg/l whereas at the 500 mg/l, a slight depression in water imbibition was observed. At dalapon concentrations of 1 to 100 mg/l, a marked stimulation in total water imbibed by quackgrass seeds was shown during the 10-h period.

    Germination Promotion of Loblolly Pine and Baldcypress Seeds by Stratification and Chemical Treatments (1972)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 27 (1972), S. 0 
    Details

    Topics: Biology
    Notes: The effects of 4 chemicals on the germination promotion of stratified and unstratified seeds of loblolly pine (Pinus taeda) and baldcypress (Taxodium distichum) were studied. The chemicals used were gibberellic acid, kinetin, potassium nitrate and thiourea, each at 3 different concentrations.Stratification promoted the germination of both seed species. Certain concentrations of gibberellic acid, potassium nitrate and thiourea improved the germination of unstratified loblolly pine and baldcypress seeds while kinetin had no stimulatory effect.All 4 chemicals at specific concentrations promoted the germination of loblolly pine seeds stratified for a short period of time. Considering both speed and completeness of germination, best results were obtained when 21-day stratified seeds were treated with either gibberellic acid (100 mg/1) or kinetin (10 mg/1). In baldcypress, on the other hand, none of these chemicals had any stimulatory effect on the germination of stratified seeds. Germination of both species of seeds was either partially or completely inhibited by the highest concentration of thiourea (30,000 mg/1) used.

    Metabolism of Maleic Hydrazide in Tea, Camellia sinensis (1967)

    Details

    Topics: Biology
    Notes: The results obtained with tea plants treated with 14C-maleic hydrazide indicate that tea plants can metabolize maleic hydrazide to some extent. According to autoradiographic studies, two radioactive spots were found on X-ray films after exposure and development. Based on two-dimensional paper chromatography, possible ring cleavage, and infrared spectroscopic techniques, the possible metabolic products are lactic acid, succinic acid, maleimide and hydrazine.The biological activity of the metabolic products was tested by utilizing the Avena first internode test. Based on this investigation, it was noted that each radioactive area contained compound(s) that possess(es) some growth promoting properties. However, the results obtained with unknown number one (U1) indicate that it possesses greater growth-promoting properties than unknown two (U2). finally, the approximate concentrations of U1 and U2 were determined by comparison with known concentrations of IAA and in relation to the amount of growth produced during the 19½-hour period of incubation.

    Effect of Chrysanthemum Plant Extract on Flower Initiation in Short-Day Plants (1966)
    Oxford, UK : Blackwell Publishing Ltd

    Topics: Biology
    Notes: An extract was prepared from Chrysanthemum plants in flower. It was separated into eight different fractions putting emphasis on the sterol components of the extracts. Fractions 5 and 6 were found to contain active substance (s), which to some extent, brought about floral bud initiation in both Chrysanthemum and Xanthium.The active substance (s) present in the above two fractions might be a sterol (s), similar to those of sitosterol and stigmasterol or other related compounds.Gibberellic acid brought about stem elongation as usual, but was found ineffective in causing any tissue differentiation in both Chrysanthemum and Xanthium.Investigations are underway to separate and identify the different compounds present in fractions 5 and 6. The effects of these compounds on test plants, both individually and in combinations, might provide some valuable information as to the nature of the flowering hormone.

    Notes: The seeds of loblolly pine (Pirns taeda L.) were cold-stratified for 0, 14, 28, 42, and 56 days. Endogenous growth regulators were extracted from these seeds, and also from the germinating and the 28-day warm stratified seeds. Partially purified extracts were separated on chromatographic paper. The chromatograms were cut into 10 equal segments, and these were tested for biological activity using three different btoassays.The results indicated that the unstratified seeds and those stratified up to a period of 28 days contained very little or no growth promoter (GA-like substances), and a relatively high concentration of an inhibitor (presumably abscisic acid), Following 42-day stratification, the promoter concentration gradually increased while the inhibitor level fell almost to zero. A high level of promoter but no inhibitor was detected in germinating seeds.No auxin-like activity was noted in the unstratified seeds. This activity slowly increased up to a period of 28 days and remained at this level for the subsequent stratification periods. However, the activity greatly increased in the germinating seeds.Very little changes in the levels of growth regulators were noted in warm-stratified seeds as compared to the unstrati-fied controls.
