  • Ethylene evolution of leaves was measured in the samples of barley and wheat grown in the various conditions and treatments. The older and stepped leaf of barley had tended to the tendency to contain more ethylene than the younger and sound leaf. Relatively high concentration of ethylene was evolved in the samples which the detecting time was delayed and so was in the samples incubated at high temperature. The higher evolution of ethylene was determined by the barley plant grown in the field and with compost application compared to the samples grown in the pot and with composite fertilizer application, however the flooding treatment resulted in decreasing ethylene evolution comparing to untreated barley and wheat. The prostrate type and higher chrolophyll content leaves of wheat appeared to produce more ethylene than erect and lower chrolophyll leaves did.

  • Barley leaves tea white bread were prepared by the addition of 0.005, 0.010, 0.015, and 0.020% hemicellulase to flour of the basic formulation. The experiments and control were then compared in terms of quality characteristics, including pH, total titratable acidity, fermentation power of dough expansion, specific volume, baking loss, moisture content, color, textural characteristics, internal surface appearances, and sensory qualities in order to determine the optimal ratio of hemicellulase in the formulation. There were no significant differences in pH and total titratable acidity of dough and bread among the experiments. Fermentation power of dough expansion were increased as incubation time increased. Bread made by the addition of hemicellulase had significantly higher specific volume than the control group. However, lightness and yellowness showed the reverse effect. Greenness was not significantly different among the samples. Baking loss was the highest at the 0.020% addition level, and moisture content was maximal with the 0.010% addition, while the lowest in the control bread samples. As hemicellulase contents increased, harness and fracturability decreased. Resilience was maximal with the 0.015% addition, and was minimal in the 0.005% group. In the sensory evaluation, color, flavor, softness, overall acceptability, barley leaves flavor, delicious taste, astringency, bitterness, and off-flavor were not significantly different among the samples. In coclusion, the results indicate that adding 0.010% hemicellulase in barley leaves tea white bread is optimal for quality and provides a product with reasonably high overall acceptability.

  • Ethanol-soluble amino acids in healthy and powdery mildew-infected leaves of the susceptible cultivar Peruvian and the adult-plant-resistant cultivar Asse of spring barley were quantitatively analysed. At I day after inoculation, the levels of amino acids in the infected first leaves of the two cultivars were similar to those of comparable healthy controls. During sporulation, increases in amino acids were more pronounced in Peruvian than those in Asse. The changes in amino acid content in the infected first and fifth leaves were closely related to the number of colonies per leaf. The susceptible cultivar Peruvian showed higher amounts of amino acids in infected first and fifth leaves at all infection intensitives than did Asse.

  • Starch contents in healthy and powdery mildew-infected spring barley leaves at first and fifth leaf stages were measured at different intervals after inoculation. Different patterns of starch accumulation in the susceptible cultivar Peruvian and the adult plant resistant cultivar Asse were found in infected first and fifth leaves. At the early phase of infection, the amount of starch in infected first leaves was slightly changed in both cultivars. During colony development and sporulation, the decrease in starch content was .more marked in the susceptible Peruvian, whereas the amounts of starch in the adult plant resistant Asse increased during colony development and then decreased sharply before and after sporulation. In heavily infected first leaves, the susceptible cultivar Peruvian showed a drastic decrease in starch content. In the adult plant resistant cultivar Asse, the higher amount of starch retained in these infected leaves, regardless of infection intensity. The regulation of starch accumulation in mildewed barley plants at different leaf stages was discussed in relation to adult plant resistance of spring barley.

  • Chemical composition of barley leaves of four varieties (Olbori, Suwon 298, Suwon 311 and Milyang 60) grown under the same environmental conditions at the same location was investigated. Barley leaf samples were collected on two weeks before heading period. The barley leaves contained $25{\sim}29%$ crude protein, $9.3{\sim}9.9%$ crude lipid, $9.3{\sim}11.2%$ ash, $1.3{\sim}1.8%$ ${\beta}$-glucan on dry matter basis. Chlorophyll contents of Olbori, Suwon 298, Suwon 311 and Milyang 60 were 951 mg%, 885 mg%, 866 mg%, 826 mg%, respectively. Mineral contents of barley leaves were not significantly different each other and potassium content was found to be the highest among all the minerals observed. Vitamin C contents of Olbori, Suwon 298, Suwon 311 and Milyang 60 were 328 mg%, 266 mg%, 278 mg% and 269 mg%, respectively. Free sugar contents of barley leaves were somewhat different and the glucose content was the highest among the free sugars, ranging from 5.70% to 8.35%. Besides glucose, fructose, sucrose and raffinose contents were also relatively higher than the other free sugars. In other oligosaccharides, 1-kestose($GF_2$) content was between 0.26% and 0.39% and a slight amount of 1-nystose($GF_3$) was also detected. Although aspartic acid, glutamic acid and serine were relatively higher content than the other free amino acids, the values were not consistent in different varieties.

  • Papilla and cytoplasmic aggregates clearly formed on the epidermal cells of barley leaves in response to the primary germ-tubes of Erysiphe graminis f. sp. hordei, but their sizes were much smaller than those in response to the appressoria. Some cells of barley leaves exposed to powdery mildew for 36-48h were more deeply stained as compared to the other cells by acid fuchsin. However, the content of malondialdehydein in powdery mildewed leaves, one of the product of lipid peroxidation, did not increase by 96h after inoculation. Positive reactions for callose, protein and phenolics were recognized in the papilla and cytoplasmic aggregates at 6h after inoculation, but cutin, suberin, cellulose and lignin were not noticeable until 72h after inoculation. The total phenol content in methanol extracts increased with increasing time after inoculation. All histochemical reactions were not race-specific in barley­powdery mildew combinations tested.

  • Combined applications of rice bran with pine leaves were tested to examine the inhibitory effects to paddy weeds and increased yield of rice for developing techniques of environment-friendly weed management in paddy rice fields. Weed control efficacy at 60 days after treatment was improved to 88.8% by combined application of rice bran with pine leaves, while weed control efficacy by single application of rice bran showed 67.5%. The other weed control efficacy combined with chestnut leaves and barley straws were 76.3% and 69.9% respectively. Combined application of rice bran with pine leaves was more effective to broadleaf weeds such as Monochoria vaginalis. Weed control efficacy by combined application with pine leaves was 100% until 70 days after rice transplanting and maintained weed control effect up to 90 days after transplanting. Rice yield by combined application of rice bran with pine leaves was 526 kg/10 a, which was higher yield than by combined application with barley straws, single application of rice bran, natural snail application and hand weeding.

  • Purpose: The aim of this study was to investigate the effects of various leaf powders on chocolate by analyzing quality characteristics, antioxidant activities, and sensory characteristics. Methods: Pine needles, mulberry leaves, ramie leaves, barley leaves, and squash leaves were freeze-dried, powdered, and added to the chocolate. Results: Water contents of all leaf powder-added groups were significantly higher than that of the control (15.78%). The pH values of chocolate with leaf powder were lower than that of the control (6.33) while that of mulberry leaf chocolate (6.56) was higher than that of the control. In color measurement, L-value, a-value, and b-value were highest in pine needle chocolate (30.31, 3.52, and 4.78, respectively). The ${\Delta}E$ value (total color difference compared to white board) was the highest in squash leaf chocolate (69.51) and significantly different from that of the control (67.69). The hardness of leaf powder-added chocolate was lower than that of the control (6.84 N), except for pine needles. In the antioxidant activity analysis, chocolate with pine needles and squash leaves had higher polyphenols, flavonoids, and ABTS radical scavenging antioxidant activity than those of the control. Overall consumer acceptability was the most preferred in the control compared to the other groups. However, chocolate with mulberry and barley leaves also received high scores (5.60 and 5.40, respectively) for overall acceptability. Conclusion: It can be concluded that chocolate with barley leaves is desirable for making functional chocolate due to its high consumer preference and positive effects on improving antioxidant activities.

  • Fifteen sheep were used in a trial which compared the feeding value of whole barley gain and cottonseed cake as supplements to a basal diet of leaves of fourwing saltbush (Atriplex canescens). Diet SB contained 700 g (air-dry matter) of saltbush alone, diet SB + BG contained 700 g SB with 400 g whole barley grain and diet SB + CS contained 700 g SB with 400 g cottonseed cake. The digestibility of the dry matter of diets SB (69%) and SB + CS (70%) were lower (p < 0.001) than of diet SB + BG (76%). Sheep offered SB alone daily lost 80g whereas those fed the other diets gained 11 g (SB + CS) or 17 g (SB + BG) per day. Daily water consumption of the sheep offered the three diets was similar (p > 0.05), but their water consumption was higher (p < 0.001) than that of sheep offered daily 700 g wheat straw and 200 g barley grain. The results indicate that, at the levels of feeding used, barley grain and cottonseed cake had similar value as supplements to fourwing saltbush harvested in summer. The addition of the supplement allowed the sheep to gain some live weight. However, the presence of saltbush leaves in the diet resulted in higher water intakes by the sheep.

  • Freezing-resistant plants can survive subzero temperatures by withstanding extracellular ice formation. During cold acclimation, their leaves accumulate antifreeze proteins (AFPs) that are secreted into the apoplast and have the ability to modify the normal growth of ice crystals. Three barley, two wheat and two rye cultivars were grown under two different temperature regimes (20/16$^{\circ}C$ and 5/2$^{\circ}C$, day/night). Apoplastic proteins from winter cereals were separated by SDS-PAGE and detected with antisera to AFPs from winter rye. Apoplastic proteins accumulated to much higher levels in cold-acclimated (CA) leaves compared with nonacclimated (NA) ones in winter cereals. After cold acclimation, the protein concentration of apoplastic extracts increased significantly from 0.088 $mgmL^{-1}$ to 0.448 $mgmL^{-1}$, with about 5-fold increment. Also, the apoplastic protein content per gram leaf fresh weight in CA leaves ranged from 31 $\mu\textrm{g}$ $(gFW)^{-1}$ to 120 $\mu\textrm{g}$ $(gFW)^{-1}$ with an averaged value of 77 $\mu\textrm{g}$ $(gFW)^{-1}$, and coefficients of variation of 54.9%. The CA leaves in Musketeer (a Canadian winter rye cultivar) showed the greatest AFPs and antifreeze activity followed by 'Geurumil' (a Korean winter wheat cultivar), and 'Dongbori l' (Korean facultative barley cultivar). The proteins secreted into the wheat leaf apoplast at CA condition were more numerous than those observed in winter rye, where two $\beta$-1,3-glucanase-like proteins (GLPs), two chitinase-like proteins (CLPs) and two thaumatin-like proteins (TLPs) accumulated during cold acclimation. The proteins in barley leaf apoplast at CA conditions were a little different from those in wheat leaves. The AFPs were various among and within species. More freezing-resistant cultivars had more clear and numerous bands than less freezing-resistant ones. The high determination coefficient ($R^2$ =91 %) between freezing resistance and AFPs per gram leaf fresh weight indicated that the amount of AFPs was highly related to freezing resistance in winter cereal crops.
