  • Total 29 commercial crucifer seed lots were tested for seed transmission of Xanthomonas campestris pv. campestris by seed washing liquid plating assay. One imported cabbage seed lot was found to carry Xanthomonas campestris pv. campestris. Several methods and chemicals for eradication of Xanthomonas campestris pv. campestris in and on the cabbage seed were tested for effectiveness. Soaking cabbage seed in $3\3%$ hydrogen peroxide solution for 30 minutes effectively eradicated Xanthomonas campestris pv. campestris in a naturally infested seed lot. In a field survey, black rot turned out to be an important disease in cabbage in Korea.

  • 녹색꽃양배추는 이용부위를 기준으로 할 때 화채류로 분류되어 화전을 수확대상으로 하며 화뢰의 발육적온은 15-18℃로, 재배시기가 고온에 가까워지는 초여름부터 초가을 수확의 작형에서는 화뢰형성 불량 등 이상화뢰의 발생이 많아지게 된다(Fujime와 Hirose, 1981). 특히 봄철 노지 재배에서는 15-25℃의 생육적온을 벗어나는 저온과 고온에 조우될 위험성이 크며, 생육초기의 저온과 후기의 고온이 품질저하의 원인이 되므로 (Takuya와 Tugio 1994), 무리한 조기정식을 피하고 가능한 6월 중순 이전에 수확을 마쳐야 한다.

  • Effects of cold plasma treatment (CPT) against Salmonella Typhimurium inoculated on cabbage and lettuce, naturally occurring bacteria in black pepper powder and red pepper powder, and Bacillus cereus inoculated onto red pepper powder were investigated. The numbers of S. Typhimurium on cabbage and lettuce were reduced by $1.5{\pm}0.2CFU/cm^2$ (900W, 5 min) and $1.1{\pm}0.1$ log $CFU/cm^2$ (900W, 10 min), respectively. The numbers of naturally occurring aerobic bacteria in both black pepper powder and red pepper powder were reduced by $2.3{\pm}0.3$ and $0.6{\pm}0.2$ log CFU/g, respectively. The numbers of B. cereus vegetative cells on red pepper powder were reduced by $1.5{\pm}0.1$ log CFU/g, but the numbers of spores remained unchanged. The inhibition of S. Typhimurium on cabbage was adequately described by Fermi's model and the Weibull model. The predicted optimum treatment power and time for S. Typhimurium inoculated onto cabbage were 746 W and 6.8 min, respectively. Our results indicate that CPT represents a useful method for microbial decontamination of vegetables and spices.

  • Whole apples were cut with a sharp or dull knife, and whole cabbages and crisp lettuce heads were cut into salad or thin strips with a knife or by hand. The fresh-cut apples, cabbages, and lettuce were packed in low-density polyethylene bags and kept at $4^{\circ}C$, and their qualities were investigated. Browning and softening of the apples that were cut with a sharp knife were more delayed than those of the apples that were cut with a dull knife. The soluble solids and pH of the fresh-cut apples were not affected by the sharpness of the cutting blade. The browning indexes of the fresh-cut cabbages and lettuce were significantly lower in the samples that were cut with a knife than by hand and in the samples that were cut into large pieces. The results suggest that the cutting blade sharpness, cutting tools, and cut types affected the quality of the fresh-cut apples and leafy vegetables, and that the cutting methods which minimized the cutting damage should be used to retard the browning and softening of the produce.

  • In Brassica, S locus glycoprotein (SLG) and S locus receptor kinase (SRK) genes function together for self-recognition in the self-incompatibility response. In addition, a water channel called aquaporins (MOD) is required for the self-incompatibility response. In this study, we isolated the SC-SLG, SC-SRK, and SC-MOD genes from a self-compatible line of B. oleracea. In the self-compatible line, the SC-SLG, SC-SRK, and SC-MOD genes showed the highest degree of sequence similarity with published data and to normal expression by RT-PCR. Therefore, it can be concluded that the SCR/SP11 gene of the B. oleracea pollen may not function and/or that mutations may occur in genes for self-incompatibility that are not linked to the S locus region.

  • Flow properties of red flower cabbage pigment solutions were determined over a wide range of temperatures ($20-50^{\circ}C$) and soluble solid concentrations (1-65%) using a cone and plate rotational viscometer. Flow properties of the pigment solutions were adequately described by the simple power law model. Within the tested ranges of concentration, temperature and shear rate, the flow behavior index (n) and the consistency index (K) of the solutions were in the ranges of 0.841-0.998 and $0.008-31.525\;Pa{\cdot}s^n$, respectively. The effect of temperature on the apparent viscosity of the solutions followed an Arrhenius type relationship. Activation energy of flow varied from 9.36 to 52.48 kJ/mol depending on the solid concentration and shear rate. The combined effect of temperature and concentration on the apparent viscosity at the shear rate of $100\;s^{-1}$ could be represented by a single equation as ${\ln}\;{\eta}_a\;=\;6.11\;-\;3103.94(1/T)\;-\;0.03C$.
