    Notes: The effect of germination on the blood hem agglutinating activity (BHA) of eight varieties’ of pea and bean seeds was studi Ed. Among seeds, the BHA of Wando, Laxton Progress, Pinto and soybean was the highest, that of Mung bean was the lowest. The BHA decreased progressively with days of germination. After 4 days of germination, the BHA of seeds decreased to the following percentages of ungerminated seeds: Dwarf Gray pea, 16.3%; Early Alaska pea, 8.1%; Laxton Progress pea, 5.3%; Mammoth Melting pea, 9.1%; Wando pea, 5.1%; and soybean, 3.7%. The BHA of Mung bean and Pinto bean disappeared completely after 4 days of germination. This study shows that an antinutritive factor, hemagglutinin, of seeds was decreased by germination.

    Notes: The anthocyanins of Royalty grapes were extracted with methanol containing 0.1% HCI and purified by adsorption on cation-exchange resin, and the individual pigments separated by paper chromatography. Acid hydrolysis and chromatographic characteristics provided information on the nature of the acyl and sugar moieties of the anthocyanins. The anthocyanins were identified by their Rf values, sugar moiety, alkaline-degradation products of the anthocyanidins, partial acid hydrolysis, and spectral characteristics in the visible and ultraviolet regions. The pigments, in decreasing order of concentration, were malvidin-3,5-diglucoside, malvidin-3,5-diglucoside acylated with p-coumaric acid, malvidin-3-monoglucoside acylated with p-coumaric acid, malvidin-3-monoglucoside, peonidin-3,5-diglucoside, malvidin-3,5-digluco-side acylated with caffeic acid, peonidin-3-monoglucoside, peonidin-3-monoglucoside acylated with i)-coumaric acid, and peonidin-3,5-diglucoside acylated with p-coumaric acid. The presence of 3-glucosides of cyanidin, delphinidin, and petunidin, and 3,5-diglucoside of petunidin is indicated.

    Notes: A fermented milk model system was employed to investigate the volatilities of butyric, caprylic, and caproic acids as affected by low, intermediate, and high levels of carrageenan, guar and xanthan gums. Carrageenan exhibited no effect on fatty acid volatility. Intermediate levels of guargum increased the volatility of caprylic acid. Low and high levels of guar gum had no effect on free fatty acid volatility. At low and high levels, xanthan gum had no effect on volatilities of fatty acids. The intermediate level of xanthan gum increased volatilities of caproic and caprylic acids. The effects of viscosity were potentiated with increased fatty acid chain length.

    Notes: Surfactant-enhanced subsurface remediation is being evaluated as an innovative technology for expediting ground-water remediation. This paper reports on laboratory and modeling studies conducted in preparation for a pilot-scale field test of surfactant-enhanced subsurface remediation. Laboratory batch and column studies evaluated the surfactant-contaminant ground-water interactions in an effort to properly design the field-scale demonstration. A series of laboratory tracer tests and numerical simulations were completed to demonstrate the effectiveness of the hydraulic system (a vertical circulation well—VCW) for capturing injected solutions in a shallow, highly conductive, unconfined ground-water formation. The results of these studies were then used to optimize the performance of the VCW system during the subsequent field-scale demonstration study which utilized the VCW for injecting and extracting a surfactant solution. Information from the simulation studies, combined with the results of the batch and column tests, was crucial for procuring regulatory approval for the field demonstration, and successful design of the field-scale demonstration.

    Notes: Two different vertical circulation well (VCW) systems (Type A and Type B) were used to detect and subsequently remove tetrachloro-ethylene (PCE) spilled in a three-dimensional sand tank. The Type A system has one injection interval and one extraction interval. The Type B system has two injection intervals separated by an intermediate extraction interval. PCE was detected through partitioning tracer tests using ethanol and 2,2-dimethyl-3-pentanol as the non-partitioning and partitioning tracers, respectively. The concentration breakthrough curves for the tracers exhibited significant chromatographic separation due to partitioning of the 2,2-dimethyl-3-pentanol into the PCE. Because of the unique streamline distribution generated by the VCW systems, injected solutions did not sweep through the entire contaminated pore volume, which resulted in less than 100 percent detection of the spilled PCE. However, multiple tests along the borehole of the well were used to delineate the vertical profile of PCE residual saturation. Three food- grade surfactants were used to remediate the spilled PCE. For surfactant-enhanced solubilization, the PCE effluent concentrations for the VCW systems were approximately eight (Type A) and 13 (Type B) times higher than that of a pump-and-treat system using water alone. The VCW effluent concentrations are actually diluted because the extraction rate exceeds the injection rate. Removing the effects of dilution occurring in the borehole, the concentrations leaving the treatment zones around the VCW are found to be 32 (Type A) and 52 (Type B) times higher than using water alone. During surfactant-enhanced mobilization, the Type A VCW system was unable to capture all of the PCE-surfactant microemulsion as it migrated downward. The uncaptured PCE could have negative impacts on ground water quality due to its increased solubility. The Type B system was found to be hydraulically more efficient than the Type A system both in terms of overall PCE removal and capturing mobilized microemulsions.

    Notes: Abstract. At present about half of the N fertilizer used in China is as urea. However, recovery of urea N in crops is often limited to 30–40%. Application of urea in combination with hydroquinone plus dicyandiamide (U-HQ-DCD) gave an improved urea-N recovery and grain yield by spring wheat in a pot experiment. The apparent total urea-N recovery was 69% and 73% of this recovered N was found in the grain. The grain yield was 32% higher than in the treatment where urea was applied without inhibitors. The application of hydroquinone and dicyandiamide also resulted in a smaller soil nitrate content, which might restrict post-harvest leaching of N. Another beneficial effect of these inhibitors was that the N2O emission from the soil—plant system was reduced by 35% compared to the treatment where only urea was applied. The use of urea in combination with hydroquinone plus encapsulated calcium carbide gave smaller beneficial effects.

    Notes: For the discrimination of tea germplasms at the inter-specific level, four tea species and varieties (Camellia sinensis, C. sinensis var. assamica, C. sinensis var. pubilimba, C. sinensis var. kucha) and their 20 wild allied species (C. sp.) preserved in the China National Germplasm Tea Repositories (CNGTR) were investigated using randomly amplified polymorphic DNA (RAPD) markers. Fifteen primers were chosen from the 61 screened for RAPD amplification. The average DNA polymorphic frequency of RAPD primers at the inter-specific level was 0.30, varying from 0.16 to 0.60, lower than that at the intra-specific level. Using the presence, sometimes absence of unique RAPD markers, it was possible to discriminate 14 of the germplasms investigated. No single primer could discriminate all the 24 germplasms. However, OPO-13 provided rich band patterns and it could discriminate 10 genotypes. The combination of two and three primers made it possible to discriminate 15 and 21 germplasms, respectively. Furthermore, the combination of band patterns or the DNA fingerprinting based on specific RAPD markers generated by OPO-13, OPO-18, OPG-12 and OPA-13 allowed the discrimination of all 24 germplasms investigated. Therefore, RAPD markers also provide a powerful tool to differentiate tea germplasms at the inter-specific level.
