This study was conducted to standardize ingredient ratio and preparation method of mafor traditional special kimchies in kyungsang province, korea. There were about 35 varieties of special kimchi in Kyungsang province. Six varieties of them such as burdock kimchi, wild leek kimchi, green thread onion kimchi, perilla leaf kimchi, Godulbaegi(Korean wild lettuce) kimchi, and red pepper leaf kimchi were selected, because they tasted good and the physiological functions of their main ingredients were excellent. The ingredient ratios of the selected special kimchi were standardized through surveying hereditary preparation of some families in kyungsang province and using the literatures including cooking books. The standardized ingredient ratio of the burdock kimchi was 15.1 pickled anchovy juice, 6.8 red pepper powder, 5.7 garlic, 2.2 ginger, 18.0 rice flour paste, 13.5 green thread onion, and 1.2 sesame seed in proportion to 100 of burdock. The standardized preparation step of the selected special kimchies was similar except some preprocessing methods of main ingredients. The diagonally cut-up burdock ws usually parboiled or soaked in salted water, then it was mixed with the other ingredients. Wild leek and green thread onion were usually pickled with salt or pickled anchovy juice. Sometimes the green thread onion pickled was dried in the sun. General preprocessing of perilla leaf, Korean wild lettuce, and red pepper leaf was soaking them in salted water for about 5-10 days. Sometimes red pepper leaf was heated with steam and dried in the sun, then it was mixed with the other ingredients.

Forage productivity of two sorghum hybrids, Pioneer(P) 931 and P 956 and a sorghum-sudangrass hybrid, P 988, was studied. The 1st-cut of sorghun hybrids was made for silage 6 times from heading stage at a week-interval and regrowth (2nd-cut) was harvested on Oct. 13 although plants were not reached the same growth stage of 1st-cut. However, the 1st- and 2nd-cut of sorghum-sudangrass were made for green fodder 6 times from 4 weeks before heading stage at a week-interval. 1. Percent dry matter(DM) of 1st-cut of sorghum and 1st- and 2nd-cut of sorghum-sudangrass increased as growth stage advanced. Percent DM of 2nd-cut of sorghum decreased as the 1st-cut date delayed due to insufficient growing period on Oct. 13. 2. In the 1st-cut of sorghum the proportion of leaf blade (LB) or culm+leaf sheath (LS) to total DM decreased, but that of panicle increased as growth stage advanced. The panicle proportion of P 956 increased and culm+LS decreased more rapidly compared with those of P 931. IIowever, in sorghum-sudangrass hybrid the proportion of LB decreased and culmf LS increased as growth stage advanced through heading stage. 3. In the 1st-cut of sorghum hybrids crude(C) protein and C. fiber decreased, but nitrogen free extract (NFE) increased as growth stage advanced although C. fat and C. ash were similar among the growth stages. In the 2nd-cut of sorghum C. protein and C. ash increased, but NFE decreased as harvesting date delayed due to plants were younger although C. fat and C. fiber were similar among the harvesting dates. In the sorghum-sudangrass C. protein of 1st-cut decreased, but C. fiber of 1st-cut and NFE of the 1st-and 2nd-cut increased as growth stage advanced. 4. DM yield of 1st-cut of sorghum increased from heading stage to 3 weeks after heading and then levelled off, but total DM including regrowth was similar among the harvesting time. In the sorghum-sudangrass hybrid DM yield of 1st-cut and total DM yield including 2nd-and 3rd-cut increased as the harvestingtime delayed.
Objective of this Research was to determine the influence of foliar application of $CaCl_2$ or $K_2SI_2O_5$ and soil application of $CaCO_3$ or $SiO_2$ on growth and cut flower quality of Zantedeschia aethiopica 'Wedding March'. To achieve this, $CaCl_2$ or $K_2SI_2O_5$ were applied at six leaf stage with the concentration of 0.05, 0.1 and 0.2% and $CaCO_3$ or $SiO_2$ were applied as basal fertilization with the amount of 100, 200, 400kg per 10a or 50, 100, 200, 400kg per 10a respectively. Plant material was used Zantedeschia aethiopica 'Wedding March'. Among calcium chloride($CaCl_2$) and calcium carbonate($CaCO_3$), calcium chloride foliar application was more effective than calcium carbonate with basal fertilization to growth of common calla 'Wedding March'. In the 0.1% solution foliar application of calcium chloride, plant height, leaf length and length of cut-flower was more longer than control. Length of leaf petiole was more longer and leaf fresh weight was more heavier than control. The degree of petiole hardness was more effective in the 0.1% solution calcium chloride foliar application than any other treatment. In the silicate fertilization treatment, plant height of 50kg per 10a treatment was most highest as 73.9cm. also its length of leaf petiole and leaf fresh weight was more effective than any other treatment. The hardness of petiole was better in the 50kg per 10a silicate fertilizer treatment. The cell shape of leaf petiole was round and tissue was regular in the treatment of 0.1% calcium chloride and 50kg per 10a silicate fertilizer but the cell of control was irregular round type. Macro element content of calcium was more amount in the treatment of silicate 50kg per 10a basal fertilization. The infected ratio of Erwinia was no relation with lime and silicate fertilizer treatment. Lime fertilizer treatment is effective for growth and flowering of Calla than silicate fertilizer and the suitable concentration was 0.1%.
Synchrotron X-ray micro imaging technique was employed to non-invasively monitor the water flow inside xylem vessels in a bamboo leaf. The phase contrast X-ray images clearly visualized plant anatomy and the rise of a water front inside the vessels. Consecutive X-ray images taken for 60 seconds revealed water rise kinetics against gravity in the xylem of a cut dry leaf taken from a bamboo tree. For the first time, traces of water rise, variation of contact angle between water and xylem wall as well as the internal structure of xylem were obtained. In xylem vessels, a repeating flow pattern has a typical flow velocity of $30.7{\mu}m/s$ and faster flow is established intermittently. It is concluded that the transmission type of X-ray micro imaging can be used as a powerful tool to investigate the ascent of sap in the xylem vessels at a resolution higher than that of MRI.
Effects of BA treatment and cut planting methods on shooting and seedling characteristics were investigated to increase seedling products by cuttings of lacquer tree. Dipping on 1,000mg/L BA solution was better than dripping with same solution at 5 weeks after cut planting. As shooting rate was increased suddenly, it was 85% at 10 weeks after cut planting. Among 3 dripping treatments, interval was not effective on shooting rate. Dripping per 2 days with 100 ㎕ of 1,000 mg/L BA solution was most effective on seedling height and leaf number and than dipping was more effective than dripping per 5 and 7 days. Branch developed on near part from dripped scion. Shooting of horizontal planting was earlier about a week and rate was increased suddenly from 3 to 6 weeks, it was highest with 96% than others at 10 weeks after planting. Seedling of horizontal cut planting was tallest about 40cm and branch developed lower than vertical and oblique cut planting. In case of horizontal cut planting, 2-3 shoots were formed on different part of scion and than those were could divided to seedling, so horizontal cut planting was most effective to propagation of seedling than any others.
Mulberry plants cultivated in mid-Korea were studied on the growth habitat, canopy type, productive structure and vertical light intensity in relation to the quality of mulberry leaves for sericulture. The growth in length of new branch of summer cut mulberry in spring was vigorous on the uppermost of old shoot. Numbers of leaves on a branch were barely 4 leaves on lower than 20th branch from base, but those were 13 leaves on higher than 24th branch. Area of leaves completely expanded was broad on high branch, but narrow on low one. The form of canopy, the type of productive structure and the vertical light distribution depend upon varieties of cultivated mulberry plants were classified according to characteristic of each variety in two groups, respectively; globular and columnar form in canopy, broad leaves and narrow leaves types in productive structure, and seriously obstructured the light and fairly transmitted the light into lower leaf stratum invertical light distribution. Out of varieties of mulberry investigated, Suwon No. 4 and Rosang were belong to the former characters, but Illchiroe and Kaeryangsubun were to the latters. The values of leaf dry matter index and dry matter production produced by leaves were increased in direct proportion to the height of leaf stratum; the leaf dry matter index of the uppermost leaf was twice as much that of the lowest, and the dry matter production by the highest leaf was 17 times compared with that by the lowest leaf. It is assumed that the meagre leaves occurred in the lower leaf stratum of Suwon No. 4 and Rosang were caused to diminished the dry matter index and dry matter production in the under leaves of plant, which were affected by receiving the weak light.
A new hybrid variety of pasqueflower, 'Yeonhong', was derived from an interspecific cross between Pulsatilla davurica and P. koreana at the Jeollanamdo Agricultural Research and Extension Services (JARES) in Naju, Korea. The original cross was performed in 2001, and the 'Yeonhong' hybrid was established in 2003 after two years of selective breeding. 'Yeonhong' is characterized by deep pink flowers and is self-incompatible. The inherent characteristics of the variety are deep yellow anthers, a deep pink stigma, six petals, and green leaf color. 'Yeonhong' blooms twice a year. The agronomic characteristics of the variety are 26.5 flowers per plant, 58.6 cm in flower height, 46.8 cm in cut flower length, 11.5 cm in bract width, and 34.4 cm in leaf length. Flower characteristics include 8.4 days of longevity for cut flowers and 34 days of longevity for bracts. The new variety is suitable for use as a cut flower.
This study was carried out to determine the economic injury level of the rice leaffolder,Cnaphalocrocis medinalis G.. The damage aspects of rice plant (at tilling stage) by leaf folders at different larval density per plant were studied in pot experiment (24 cm in diameter, 18 cm in height). One leaf folder consumed 6-7 leaves during larval stage. The damage by leaf folders was simulated by cutting off 0, 10, 30, 50, 70, and 90% of leaves before and after heading stage July 15th (at panicle initiation stage) and August 15th (at milk stage), respectively. When leaves were cut before the heading of rice, the linear relationships between the leaf cutting rate (X) and each factors of yield (Y) were as following; for grain maturity it was Y = -9.379X + 83.630 ($R^{2}=0.493$),\;Y = 0.139X + 0.490 ($R^{2}=0.925$) for yield, and Y = -4.880X + 81.116 ($R^{2}=0.665$) for head rice. When leaves were cut after the heading of rice, it was Y = -23.0l4X + 83.589 ($R{2}=0.915$), for grain maturity, Y=0.141X + 3.466 ($R^{2}=0.842$) for yield, and Y = -13.795X + 81.964 ($R^{2}=0.898$) for head rice. We found that when leaf cutting after the heading stage caused more damage than before the heading in terms of yield and yield components. Based on theses results the economic threshold level was estimated to be 30% and 7% leaf loss before and after heading stage.

On multimedia databases, in order to realize the fast access method, indexing methods for the multidimension data space are used. However, since it is a premise to use the Euclid distance as the distance measure, this method lacks in flexibility. On the other hand, there are metric indexing methods which require only to satisfy distance axiom. Since metric indexing methods can also apply for distance measures other than the Euclid distance, these methods have high flexibility. This paper proposes an improved method of VP-tree which is one of the metric indexing methods. VP-tree follows the node which suits the search range from a route node at searching. And distances between a query and all objects linked from the leaf node which finally arrived are computed, and it investigates whether each object is contained in the search range. However, search speed will become slow if the number of distance calculations in a leaf node increases. Therefore, we paid attention to the candidates selection method using the triangular inequality in a leaf node. As the improved methods, we propose a method to use the nearest neighbor object point for the query as the datum point of the triangular inequality. It becomes possible to make the search range smaller and to cut down the number of times of distance calculation by these improved methods. From evaluation experiments using 10,000 image data, it was found that our proposed method could cut 5%~12% of search time of the traditional method.
This thesis emphasize on diurnal changes of leaf water potential in relation to differences of cutting arrangement. 1. The more is leaves attached to the cutting, the higher is water stress in the cutting compared with less leaves. 2. The less is diameter of cut-part, the more are shown changes in increased and decrease in diurnal leaf water potential. 3. The more is length of stem, the more are shown water stress in diurnal leaf water potential 4. There is no differences between earthen-ball cutting and non-earthen ball cutting in diurnal leaf water potential. 5. Cuttings with two year's slip, compared with one year's leaf water potential increases slowly, dry weigh of root and numbers of rooted cutting are most likely dependent upon other factors rather than the water stress.
