  • This study was conducted to understand the characteristics of fruit softening during ripening which causes deep loses in quality of horticultural products during storage and marketing process after harvest. The changes of cell wall components during ripening was investigated. The climacteric rise was between 42 and 49 days after anthesis and then decreased. Ethylene evolution was similar to respiration. The hardness of fruit decreased markedly at this climacteric period and significances of textural parameters among the ripening periods were recognized but the significance between 50 and 55 days after anthesis was not. Sugar components of cell wall polysaccharides were uronic acid, galactose, glucose, arabinose, xylose, rhamnose, mannose and fucose. The contents of arabinose and mannose in alcohol-insoluble solids fraction increased, but other sugars were not changed. In cell wall fraction, the contents of uronic acid, galactose, glucose and arabinose were comparatively high, but galactose, arabinose and ironic acid were decreased markedly during ripening. ironic acid occupied above 75% of total monosaccharide in pectin fraction and decreased markedly during ripening. In acid-soluble hemicellulose fraction, the contents of uronic acid, glucose, galactose and rhamnose were high and they decreased from 50 days after anthesis. The contents of glucose and xylose were high in a alkali-soluble hemicellulose fraction and they decreased markedly at 55days after anthesis.

  • This study was carried out in the Chungnam National University grassland experimental field from October, 2007 to December, 2009 in order to find out the growth characteristics, seasonal anthesis distribution and botanical composition of the wildflowers which were altogether composed of 70% sheep fescue and 30% wildflowers. The experimental wildflower species contained 30 species in total to which sheep fescue (fundamental turfgrass), 8 native wildflowers, and 22 introduced wildflowers belonged. At the time of the anthesis of the wildflowers, the average length was 28.3 cm one year later and 34.5 cm two years later. They bloomed out into eight colors, but into simplified two colors during August, September, and October. The blooming season leant toward May and June and from August there was lots of difficulty in the wildflower blooming and the maintenance of their consistency. Especially, at the age of two (2009), the annual wildflowers after wintering were reduced but on account of domestic wildflowers the color, seasonal distribution, and consistency showed improved compared with those of one-year-old wildflowers. The annual ration of wildflowers, sheep fescue, and weed came to 25%, 61%, and 14% each one year later (2008) and 24%, 62%, and 14% each two years later (2009). Based on this result, cultivating wildflower grassland in the combination of native wildflowers and introduced wildflowers is estimated to be the proper method in the aspect of interaction.

  • The purpose of this study was to suggest the growth characteristics, seasonal anthesis distribution and botanical composition of wildflower pasture. The experimental wildflower were 34 species (1 turfgrass species, 4 native wildflower species and 29 introduced wildflower species). The experiment were administered in the Chungnam National University experimental field from March, 2008 to December, 2009 and the result is as follows: the wildflower length were within the range of 8-60 cm and their up-and-down space arrangement quite good. They bloomed into several colors of nine but one or three of nine colors were biased during August, September, and October. Their anthesis was biased toward May and June, and their seasonal distribution and permanence maintenance were too difficult from August and moreover two years later (2009) because of the decrease of the botanical distribution of annual wildflower after winter, the color, seasonal distribution, and permanence of wildflower became a problem. The botanical composition of wildflower, turf grass, and weeds came to 24%, 62%, and 14% each one year later (2008) and two years later (2009) 16%, 69%, and 15% each. Being grounded upon this result, in case of wildflower pasture of spring seeding, it is more important to maintain the color, seasonal distribution, and permanence of wildflower two years later than in the establishment year.

  • This study was carried out in the Chungnam National University grassland experimental field from October, 2007 to December, 2009 in order to find out the growth characteristics of the wildflowers, the seasonal anthesis distribution of the wildflowers and the botanical composition of the wildflowers which were altogether composed of 50% sheep fescue and 50% wildflowers. The experimental species contained 34 species in total consist of sheep fescue (fundamental turfgrass), 4 native wildflowers, and 29 introduced wildflowers belonged. At the time of the anthesis of the wildflowers, the average length was 30.0 cm one year later and 35.6 cm two years later. They bloomed out into ten colors, but into simplified colors during August, September, and October. The peak of the blooming was May and June and blooming pattern leant from August to October. Especially, at the age of two (2009) the color, seasonal distribution, and consistency emerged as problems owing to the reduction of annual wildflowers after winterization. The annual botanical composition of wildflowers, sheep fescue, and weed came to 28%, 55%, and 17% each one year later (2008) and 24%, 60%, and 17% each two years later (2009). Based on this result, cultivating wildflower grassland (sheep fescue 50% + wildflowers 50%) is the proper method for making up such flatlands as parks and riversides in a short period (one year) for the purpose of commanding a fine view.

The experimental species contained 23 species in total to which sheep fescue (fundamental turfgrass) and 22 introduced wildflowers belonged. At the time of the anthesis of the wildflowers, the average plant height was 29.7 cm at first growing season and 34.1 cm at second growing season. They bloomed out into eight colors, but into simplified two colors during August, September, and October. The blooming season leant toward April and June and from August there were lots of difficulties in the wildflower blooming and the maintenance of their consistency. The botanical composition of wildflowers, sheep fescue, and weeds were 21%, 64%, and 15% in the first growing season (2008) and 19%, 65%, and 16% respectively, in the second growing season (2009). Based on this result, cultivating the introduced wildflower grassland has more difficulty because there is some difficulty in the wildflower seasonal distribution and the maintenance of its consistency. And thus, the introduction of more various wildflower such as perennials and flowers blooming after summer, and the seed-mixture combination method should be studied.

  • In southeastern regions of the US, herbage systems are primarily based on grazing or hay feeding with low nutritive value warm-season perennial grasses. Nutritious herbage such as annual ryegrass (Lolium multiflorum Lam.) may be more suitable for preserving as baleage for winter feeding even with more intensive production inputs. Emerging in-line wrapped baleage storage systems featuring rapid wrapping and low polyethylene film requirements need to be tested for consistency of storing nutritive value of a range of annual ryegrass herbage. A ryegrass storage trial was conducted with 24-h wilted 'Marshall' annual ryegrass harvested at booting, heading and anthesis stages using three replicated in-line wrapped tubes containing ten round bales per tube. After a six-month storage period, nutritive value changes and fermentation end products differed significantly by harvest stage but not by bale location. Although wilted annual ryegrass exhibited a restricted fermentation across harvest stages characterized by high pH and low fermentation end product concentrations, butyric acid concentrations were less than 1 g/kg dry matter, and lactic acid was the major organic acid in the bales. Mold coverage and bale aroma did not differ substantially with harvest stage or bale location. Booting and heading stage-harvested ryegrass baleage were superior in nutritive value to anthesis stage-harvested herbage. Based on the investigated nutritive value and fermentation characteristics, individual bale location within in-line tubes did not significantly affect preservation quality of ryegrass round bale silages.
