The effect of sowing date on grain protein, hordein fraction content and malting quality of two-rowed spring barley was investigated by using ten commercial cultivars with different grain protein content and the relationships among these traits were examined. The results showed that grain protein content and B hordein content increased as the sowing date postponed and were significantly affected by sowing date, while C and D hordein contents were less influenced by sowing date. There were significant differences in grain protein and hordein fraction content among the ten cultivars. The coefficient of variation of D hordein content was much larger than that of B and C hordein contents, suggesting its greater variation caused by different sowing dates. Beta-amylase activity and diastatic power were also significantly affected by sowing date, with malt extract being less affected. Significant differences in measured malt quality were found among the ten cultivars. Grain protein was significantly correlated with B hordein and malt extract positively and negatively, respectively. There was no significant correlation between beta-amylase activity or diastatic power and grain protein content. B hordein was negatively and significantly correlated with malt extract, but no significant correlations between C hordein, D hordein and malting quality traits.

OBJECTIVETo establish seed quality classification standard of Dipsacus asperoides.

METHODThrough the detection on seed purity, 1 000-grain weight, water content, germination rate of D. asperoides from different areas, and observation on seed external characters, the primary seed quality classification standard of D. asperoides was preliminarily formulated.

RESULTSThe first level D. asperoides seed germination rate was over 85%, 1 000-grain weight above 3.94 g, purity above 90.95%, water content lower than 9.08%. The second level D. asperoides seed germination rate was over 64%, 1 000-grain weight was above 3.57 g, purity was over 83.66%, water content was above 10.23%. The third level seed germination rate was above 35%, 1 000-grain weight was above 3.04 g, purity was above 75.51%, water content was lower than 11.37%.

CONCLUSIONGermination rate and 1 000-grain weight were the main indexes of quality classification standard, and purity and water content provide the important reference. This quality classification standard of D. asperoides was scientific and feasible, and can be used as the quality control standard of D. asperoides.

The seed-borne mycoflora of sorghum and foxtail millet collected from different growing areas in South Korea were isolated and taxonomically identified using dry inspection, standard blotter and the agar plate method. We investigated the in vitro and in vivo germination rates of disinfected and non-disinfected seeds of sorghum and foxtail millet using sterilized and unsterilized soil. The percent recovery of seed-borne mycoflora from the seed components of sorghum and foxtail millet seeds was determined and an infection experiment using the dominant species was evaluated for seedling emergence and mortality. A higher number of seed-borne fungi was observed in sorghum compared to that of foxtail millet. Eighteen fungal genera with 34 fungal species were identified from the seeds of sorghum and 13 genera with 22 species were identified from the seeds of foxtail millet. Five dominant species such as Alternaria alternata, Aspergillus flavus, Curvularia lunata, Fusarium moniliforme and Phoma sp. were recorded as seed-borne mycoflora in sorghum and 4 dominant species (Alternaria alternata, Aspergillus flavus, Curvularia lunata, Fusarium moniliforme) were observed in foxtail millet. The in vitro and in vivo germination rates were higher using disinfected seeds and sterilized soil. More seed-borne fungi were recovered from the pericarp compared to the endosperm and seed embryo. The percent recovery of seed-borne fungi ranged from 2.22% to 60.0%, and Alternaria alternata, Curvularia lunata and 4 species of Fusarium were isolated from the endosperm and embryo of sorghum and foxtail millet. Inoculation of the dominant seed-borne fungi showed considerable mortality of seedlings. All the transmitted seed-borne fungi might well be a primary source of infection of sorghum and foxtail millet crops.

Iron (Fe) deficiency and excess cadmium (Cd) in rice grain are important problems to be solved in agricultural production. Previous studies have shown that OsVIT1 and OsVIT2 are vacuolar iron transporters. In this study, wild-type ZH11 was selected as the background material and OsVIT1 and OsVIT2 were overexpressed in endosperm by using endosperm specific promoter Glb-1. Field experiments were conducted to study the effect of OsVIT1 and OsVIT2 overexpression on Fe and Cd accumulation in different parts of rice. The results showed that OsVIT1 overexpression in endosperm significantly reduced Fe content in grain by about 50%, while significantly increased zinc (Zn) and copper (Cu) contents in straw and Cu content in grain. OsVIT2 overexpression in endosperm significantly decreased Fe and Cd contents in grain by about 50%, and significantly increased Fe content in straw by 45%-120%. Overexpression of OsVIT1 and OsVIT2 in endosperm did not affect the agronomic traits of rice. In conclusion, OsVIT1 and OsVIT2 overexpression in endosperm reduced Fe accumulation in rice grain, which did not achieve the expected effect. OsVIT2 overexpression in endosperm also decreased Cd accumulation in grain and increased Fe accumulation in straw, which provided reference for iron biofortification and cadmium reduction in rice.

Using highly purified Con. A extracted from Vie seeds of canavalina ensiformis in Vietnam to make Con. A – Sepharose 4B affinity column for the expression of serum AFP and other Glycoprotein in patients which liver and breast cancer showed a high specific interaction between lectin Con. A and AFP as well as some pathological glycoprotein. That was the mainly basis for our later research on marking lectin affinity AFP in early diagnosis of hepatocellular carcinoma, especially in patients at high risk such as chronic hepatitis and cirrhosis.

Perilla is an Asian grain that consumed for food ingredient, oil crops, medicinal materials through the process of roasting. A 49-year-old male has been roasting grains for 10 years, who met with shortness of breath during the roasting perilla seeds, but not in other situations. Serum total immunoglobulin E (IgE) level, serum eosinophil count and skin prick test didn't showed significant results. Methacholine bronchial provocation test was positive (PC20 0.31 mg/mL). Specific bronchial provocation test with inhaling smoke from roasting perilla seeds showed a dual asthmatic response. Measured peak expiratory flow rate on his work place showed the result of 37% decrease at the end of work and full recovery at 6 hours after the end of work. Skin prick test to row perilla showed positive response with late symptoms. We diagnosed that the patient had an occupational asthma caused by inhaling smoke from roasting perilla seeds with IgE mediated mechanism.
