The environment of agriculture in Korea is changed very rapidly. Since the labours in fruit cultivation field are getting older, the resources and the aid materials for farming need to be multi functional and easy to use. Therefore, They have to use various kind of aid materials in field of fruit cultivation like as fruiting bag. The development of practical utilization way of embossing process for manufacturing of fruiting bag and wrapping paper of agricultural products was main purpose of this study. Embossing roll was designed in Ginyong Embo(Co.) for the embossing process of fruiting bag. The embossing treated fruiting bag was manufactured in Agro(Co.) at mill scale. The mechanical properties of embossing paper was investigated and operation efficiency of bagging was tested at field. The properties of embossed paper was satisfied for fruiting bags for cultivation of apple and pear.

As well as crop cultivation, they could not avoid automatizing and using more environmental friendly process in cultivation of fruit. And also, the consumer ask more safe fruit which is produced with more clean method. This is why the usage of aid materials for fruit cultivation like as fruiting bags are increasing. Practical utilization of wax emulsion treated water repelling fruiting bags are developed continuously and it's properties is compared properties of nomal fruiting bags. The water repelling process was developed with wax emulsion coating. After the experiment of wax emulsion preparation from paraffin and DEA and/or OA in Lab. scale, the wax emulsion was manufactured on pilot scale. The wax emulsion coated paper was prepared in mill scale coater. The water repellency and properties of emulsion coated fruiting bags were evaluated and compared with that of current fruiting bags.

Fruit bagging paper is used for protecting of fruits from insect and/or microorganisms. Generally, fruit bagging paper controled light, temperature and humidity and then it is used for good fruit color, size and taste. The physical properties of conventional(domestic and abroad) fruiting bag and wrapping paper were analyzed and compared to each other. And also, the optical properties of conventional(domestic and abroad) fruiting bag and wrapping paper were analyzed and compared to each other. The chemical additives and residual herbicide in conventional fruiting bag and wrapping paper were analyzed and compared to each other. The analyzed data was bench marked for developing water repelling paper and embossing paper.

In order to explore mycelial growth and fruiting body formation of Lyophyllum decates on different media, ten cultivation media by using cottonseed hull, sawdust, corn cob etc. as main components were designed for seven strains. The results showed that the mycelial colour of all strains are mainly snow-white, and the formula of media using corn cob as main materials was better than that using cottonseed hull and sawdust for mycelial growth, but no fruiting body was formed. The cottonseed hull medium with a small amount of sawdust, plant leaves, humus or fermented material and wheat was beneficial for fruiting formation. The incubation period for fruiting formation of strain 3001 was 108 days and the highest yield was-214.80 g/bag. Fructification of the strains tasted occurs successively in order of 3001, 1035, 1004 and 1013. It was concluded that different medium composition had significant effect on the mycelial growth and fruiting body formation.

Embossing treated fruit bagging paper was prepared with newly designed embossing roll and mechanical properties of fruit bagging paper were evaluated. The embossing technology was developed. First of all, embossing roll was designed in Ginyong Embo(Co) for the embossing process of fruiting bag. The embossing treated fruit bagging paper was manufactured in Agro(Co) at plant scale. The mechanical properties of embossing paper was investigated and operation efficiency of bagging was tested at field. The properties of embossed paper was quit satisfied for fruiting bag for cultivation of apple and pears.

This study was carried out to investigate the suitability of various agricultural by-products as basal substrates for the mycelial growth and fruiting body formation of Hericium erinaceum. For this aim, oak sawdust, cotton waste, sugarcane bagasse, Job's tears, rice hull, Chinese cabbage, and coconut waste were used as sole or mixed substrate(s). Corn waste and rice bran were used as nutrient supplements. The growth and density of mycelium, yield of fruiting body, and biological efficiency were compared among tested substrates colonized by Hericium erinaceum. The best measurement of mycelial growth and density, yield of fruiting body, and biological efficiency in a laboratory test was found in a spawn substrate composed with oak sawdust 80% and rice bran 20%. The suitability of this spawn substrate composition for Hericium fruiting body production was testified through practical tests in plastic bottles (850 ml) in a mushroom farm which had bottle cultivation facility. However, test in a mushroom farm which had plastic bag cultivation facility, best production of Hericium fruiting body (520 g per one bag) was observed in a spawn substrate composed of cotton waste 40%, saw dust 40%, corn waste 10%, and rice bran 10%.

Phlebopus spongiosus is a well-known edible ectomycorrhizal mushroom indigenous to southern Vietnam. The mushroom specimens collected from northern Thailand in this study were identified as P. spongiosus. This identification was based on morphological characteristics and the multi-gene phylogenetic analyses. Pure cultures were isolated and the relevant suitable mycelial growth conditions were investigated. The results indicated that the fungal mycelia grew well on L-modified Melin-Norkans, and Murashige and Skoog agar all of which were adjusted to a pH of 5.0 at 30 ℃. Sclerotia-like structures were observed on cultures. The ability of this mushroom to produce fruiting bodies in the absence of a host plant was determined by employing a bag cultivation method. Fungal mycelia completely covered the cultivation substrate after 90-95 days following inoculation of mushroom spawn. Under the mushroom house conditions, the highest amount of primordial formation was observed after 10-15 days at a casing with soil:vermiculite (1:1, v/v). The primordia developed into a mature stage within one week. Moreover, identification of the cultivated fruiting bodies was confirmed by both morphological and molecular methods. This is the first record of P. spongiosus found in Thailand and its ability to form fruiting bodies without a host plant.

The mycelial growth of P. coccineus strain was good in PDA and YMA, but mycelial growth was low in MEA. Light irradiation during the incubation period affected the pigment formation and density of mycelia. Mushroom of P. coccineus strain was able to produce fruiting bodies in both bottle and bag cultivation, and oak sawdust was found to be the most suitable substrate for spawn culture and cultivation. In artificial cultivation using sawdust medium, fruiting body was grown to the extent that visual observation was possible from the 15th day, and it formed about 5 days fast in the treatment group with low relative humidity. From 40 to 45 days of mushroom development, mature fruiting bodies could be harvested, and the lower relative humidity of the growing room favored mushroom development and growth. Antioxidant activity of fruiting bodies harvested from artificial cultivation showed that ABTS radical scavenging activity of bottle-cultivated and wild fruit bodies were shown at 505㎍/㎖ and 515㎍/㎖, respectively. However, fruiting bodies harvested in bag cultivation were high at 910㎍/㎖. As a result of DPPH radical scavenging activity, all extracts were found to be inactive, exhibiting IC₅₀ value of more than 2,000㎍/㎖ concentration. The ethyl acetate extract of mushrooms obtained from bottle cultivation showed the highest activity with 1,550㎍/㎖ IC₅₀ value. Methanol extract of wild fruit bodies had the highest ABTS radical scavenging activity at the same concentration (10mg/㎖).
