This research was carried out to obtain the field resistance to disease and pest, and high yielding of new Boxthorn (Lycium chinense Mill.) varieties. Growth characteristics, yield potential, correlation of trait which was related the yield and path coefficient of the domestic native varieties. two of cultivated varieties and four of introduced varieties were investigated. In growth characters of collected varieties, the stem length of collected varieties in China were slightly long. Leaf area in Jindo, Kumsan native and Yusong 1 and 2 were wider than that of other varieties. Resistance to pest iniury was very strong at China 1, Japan 1 and Yusong 2 in eriophyidmite, and also resistance to anthrax anthracnose were showed less than 10% of the rate of attack fruit at Japan 1 and China 1. Flowering stage was more early in Chungyang native than that of other varieties. Fruit size of Kumsan native, Yusong 2 were large size fruit varieties. Fruit setting number was most abundant at 1,623 in Yusong 2 which was collected variety. And dry yields of fruit per lOa was more cmparatively abundant in Yusong 2 at 86% than those of Chungyang native. The high correlation cofficienct character with fruit yield were fruit setting and branching number and leaf area. Direct effect by path anaslysis were fruit setting number (Py=0.45), and branching number was showed indirect effect.

This study was conducted to examine the effect of grafted peppers (Capsicum annuum) on different rootstocks on fruit quality. Three pepper cultivars, 'Nokkwang', 'Saengsaeng Matkkwari', and 'Shinhong' were grafted onto five commercial rootstocks that are known to be resistant to Phytophtora blight. Non-grafted or auto-grafted peppers were used as controls. Grafted plants were grown during two consecutive harvest periods by semi-forcing culture (April to August) and retarding culture (September to March the subsequent year). Full size green fruits were harvested and weighed weekly from June to August (Semi-forcing culture) and from December to March of the subsequent year (Retarding culture). The fruit size, weight, flesh thickness, and firmness were measured every month. Total marketable yield was not significantly influenced by either auto-graft of 'Nokkwang', 'Saengsaeng Matkkwari', and 'Shinhong' of pepper or grafted with the five commercial rootsctocks. By contrast, grafting influenced the apparent fruit quality of peppers. Fruit characteristics differed depending on the rootstock cultivars. However, the fruit characteristics of rootstock did not affect the fruit characteristics of scion grafted onto that rootstock. Fruit characteristics in each treatment differed among harvest time (first, second, and third harvest). Fruit quality parameters were also different as affected by the harvest period. In conclusion, apparent quality and textural property of pepper fruits were influenced by not only grafting with different rootstocks but also by the harvest period and harvest time. Accordingly, rootstock/scion combination, the scion variety and the harvest period must be carefully chosen to get the desired optimal fruit quality.

This study was carried out to evaluate biological activities to different ethanol extracts from unripened and ripened fruit (Rubus coreanus Miq.). 25% to 75% ethanol extracts of unripened and ripened fruits were similar to extract yield respectively. Yield of ethanol extract of ripened fruit were approximately 3 times higher than that of unripened fruit. 75% ethanol extract of unripened fruit showed the highest contents of total polyphenol ($180.04{\pm}0.41$ mg/g) and total flavonoid ($50.43{\pm}0.81$ mg/g). Contents of total polyphenol and total flavonoid of unripened fruit were about 2 times higher than those of ripened fruit. $IC_{50}$ values of DPPH radical scavenging activity and linoleic acid peroxidation inhibition activity of BHA and ${\alpha}$-tocopherol showed $13.19{\pm}0.21$ and $18.16{\pm}0.23{\mu}g/m{\ell}$, $4.25{\pm}0.04{\mu}g/m{\ell}$ and $5.56{\pm}0.10{\mu}g/m{\ell}$ respectively, but 75% ethanol extract of unripened fruit showed the lowest $23.85{\pm}0.10{\mu}g/m{\ell}$ and $7.34{\pm}0.07{\mu}g/m{\ell}$ among other all extracts. $IC_{50}$ values of LDL (low density lipoprotein) oxidation inhibition activity and ${\alpha}$-glucosidase inhibitory activity of 75% ethanol extract of unripened fruit showed the lowest $1.04{\pm}0.04{\mu}g/m{\ell}$ and $7.21{\pm}0.13{\mu}g/m{\ell}$ among other all extracts respectively. Specifically, 75% ethanol extract of unripened fruit has relatively better biological activities than other ethanol extracts, it could be potentially used as bioactive source for health functional foods.

This experiment was conducted to investigate planting depth, which applied the basic data for planting growth ability and mechanical planting of oriental melon. 'Gumssaragi-eunchun' variety was approach grafting to 'Shintozoa' and seedling was growing during 45 days in the 9cm pot and then planted on Jan. 16. The comparison of planting plots was carried out for four experimental plots, which were separated into 0cm, 4.5cm, 9cm, standard cultivation, and 12cm planting depth in soil. In the tunnel of vinyl house, the lowest and the highest temperature was $9.3^{\circ}C\;and\;41.2^{\circ}C$, respectively, and humidity was $59\~99\%$ during Jan. 18 and 19. The faster graft-take rate after planting was the deeper planting depth. The growth of 40 days after planting was not significant in each planting plot, except 0cm experimental plot. Fruit weight was the heaviest in 4.5cm planting depth of experimental plot but sugar content and flesh thickness were not significant in each planting depth. The more depth in planting meant the more increase in fermented fruit rate and decrease in marketable fruit rate. Marketable yield was 2,361kg per l0a in 9cm planting plot, which was $2\%\;and\;1\%$ lower than in 0cm and 4.5cm, respectively, and $11\%$ greater than in 12cm planting plot.

Nutritional and physio-chemical conditions for mycelial growth and fruit-body formation of Pleurotus florida were determined in synthetic media. Mannitol and sucrose were good sugar substances for the mycelial growth and fruit-body formation whereas less mycelial growth and no fruit-body formation was obtained with arabinose, lactose and inulin. The optimum concentration of mannitol was about 2%. Peptone as a nitrogen sources resulted in a rapid mycelial growth and fruit-body formation with higher yield, but nitrite-nitrogens inhibited the mycelial growth. The higher yield was obtained with 0.2% peptone. Among the vitamins used, the greatest mycelial growth and fruit-body formation brought about by thiamine and folic acid. $KH_2PO_4$ and $MgSO_4$ at 0.2% and 0.02%, respectively, were effective for the mycelial growth and fruit-body formation, but other inorganic salts used were ineffective. The optimum temperature for mycelial growth and fruit-body formation were $25^{\circ}C$ and $20^{\circ}C$, respectively, and light intensity of $100{\sim}500\;lux$ and pH 6.0 appeared to be effective.
