Protein spectra from 6 species of Gossypium were obtained by disc electraphoresis of seed extracts. Protein extracts were made by soaking 0.5g. of seed in 15ml of Tris-glycine buffer for 24 hours. Gels 24 hours. Gels were stained in 0.5% Amido Black solution for 1 hour, and destained in 7% acetic acid for 72 hours. Nine to 15 bands were visible in each gel. Homologies of Protein bands among the species were determined by migration velocity. Evidences obtained from electrophoretic separation of seed Protein were consistent with those from genetic, cytological, morphological and Phenogenetic methods regarding the origin of New World cultivated cottons. Possibility, however, does not exist to exclude Gossypium herbaceum from one of the Progenitors of New World cultivated cottons from electrophoretic evidences alone.

Nepal, with its unique geographical and ecological features due to its abrupt rise in altitude, plays significant role in biological evolution. Existence of numerous wild relatives of the present-day cultivated agricultural crop plants in this small Himalayan nation may serve as a potential source of several yet unidentified desirable genes that are needed for future incorporation in the improvement of cultivated crop plants. This report includes 82 different wild relatives of 41 genera under 19 families of 37 agricultural crops of Nepal(Table 1). It serves as the sample of the glossary of these wild relatives of crop plants in Nepal. Under food grain crop plants of gramineae, leguminoceae and polygonaceae families, 16 different wild species namely wild rices(7 species), wild relatives of wheat plant(3 species), wild arhar(3 species), wild fingermillets(1 species) and wild buckwheat(2 species) have been identified in different parts of the country. Similarly, under vegetable crop plants of Araceae, Amaranthaceae, Crucifereae, Cucurbitaceae, Dioscoreaceae, Labiteae, Leguminosae, Liliaceae, Malvaceae, Polygonaceae, Solanaceae and Umbellifereae, 37 different wild species-wild colocasia(1 species), wild amaranths(3 species), wild leafy vegetables(2 species), wild gourds(3 species), wild cucumber(1 species), wild yams(4 species), wild mints(3 species), wild fenugreeks(4 species), wild pea(1 species), wild beans(3 species), wild garlics(2 species), wild spinach(3 species), wild lady's finger(1 species), wild spinach(3 species), wild eggplants(2 species) and wild carrot(one species) have also been identified. In case of wild relatives of cultivated orchard plants, 11 different wild species namely wild mango(one species), wild banana(one species), wild strawberry(one species), wild pear(one species), wild cherries(2 species), wild apple(one species) and wild grapes(3 species) have been identified, Among 19 different wild species of economic crop plants, five wild species of sugarcane, one species of wild sunhemp, two wild relatives of cotton, three wild relatives of rose, two wild species of tobacco, four wild species of turmeric and two wild species of tea have also been identified. This report includes only sample of the total wild species of the present-day cultivated agricultural crop plants. Further exploration on this economic botany will help the country in cataloging the wild relatives of cultivated crop plants and their future use in crop improvement.

The goal of this suudy is to investigate the production and distribution of silk fabrics of the CHO-SUN Era. My conclusions culture was advanced as a result of its promotion by government authorities. It proceeded from south to north, and spread all over the country. The north became the center of the silkworm culture since cotton was cultivated in the south. Second, the production of silk fabrics proceeded by government orders at the beginning. But it proceeded by private enterprise at a later period. Since government-managed textile handicrafts began falling off during the 16th century, privately managed handicrafts were accomplished slowly. Third, at the same time as the introduction of natural cotton fabrics, the production of various fabrics in the CHO-SUN Era proceeded all over the country, and special production localities-formed. PYUNGAN-DO(평안도), HAMKYOUN-DO(함경도), HOANG HAE-DO(황해도), and KYUNG SANG-DO (경상도) were the main region of silk fabric production. Fourth, the silk fabrics were distributed through the capital markets and the province markets. And superior silk fabrics were distri-buted through the capital markets. And all sorts of low quality silks JU were distributed through the province market. Fifth, thus an abundance of superior silk fabrics was distributed in the CHO-SUN Era. But thequantity of production was not enough. And most of it was used in the Royal Court. The quantity of shortage was supplied by imports.

The yerba mate that grows in the subtropical forests of South America is an evergreen tree within the Aquifoliaceae family. The yerba mate (Ilex paraguariensis) tea is habitually used as a drink in Argentina, Paraguay, Uruguay, and Southern Brazil. A wild mate tree needs about 25 years to fully grow to 15 a height of meters; however, they only grow to a height of 3-5 meters when cultivated. The leaves are 7-11 cm long and 3-5cm wide with a serrated margin. Yerba mate tea-based beverages are made from the leaves and stems of the mate tree. It is known that they contain a rich content of antioxidants and polyphenol, vitamins, amino acids, minerals and colorants. Dyeing properties of a mate plant in the silk, wool, linen and cotton fabrics were investigated. Constituents of colorant of mate tea are chlorophyll and carotinoid; in addition, it has more minerals such as (Fe, Ca, Mn, Mg, Na, K, Zn, and Cu) than green tea. Mate tea colorants showed good affinity to silk and wool fabrics. It was found that the optimum condition for dyeing was 30 minutes for dyeing time, 7 for pH of dyebath, and at a dyeing temperature of $80^{\circ}C$. The maximum absorbance wavelength (${\lambda}_{max}$) of silk and wool fabrics dyed with mate tea were at 420-440nm; however, that of linen and cotton fabrics were at 400nm. K/S values of fabrics dyed under optimum conditions were 1.979 for silk fabrics, 1.541 for wool fabrics, 0.551 for linens and 0.465 for cotton fabrics. Munsell hue values of dyed fabrics measured 3.1Y-6.4GY for silk, 1.4Y-8.3Y for wool, 5.5Y-3.7GY for linen, and 5.3Y-1.3GY for cotton. All dyed fabrics showed hues in-between greenish yellow and greenyellow. Colorfastness to rubbing, perspiration and dry-cleaning of dyed fabrics with mate tea were very good; however, the grades of colorfastness to washing of dyed linen and cotton fabrics were poor, and colorfastness to light were poor.

Comparison of fruit bodies of Pleurotus ostreatus cultivar chunchu No .2 grown on the sawdust, rice straw and cotton waste substrates revealed differences in the pattern of differentiation of hyphal compartments. Required period for primordium induction of fruit bodies grown on sawdust substrate was 13 days. Physical structure shown as hardness of stipes grown on the sawdust substrate, fruit bodies were harden than control. Pileocystidia were well developed on the surface of pileus in the fruit body cultivated on rice straw. Microstructures of fruit body grown on the sawdust and cotton wastes substrates shown fast-discharge of basidiospore and sytoms ageing. Hyphae of fruit bodies formed on sawdust substrate had less stainable cytoplasmic material and many more vacuoles than hyphae of fruit bodies formed on synthetic substrate with 50% of pine sawdust, 30% of cotton seed hull and 20 of beet pulp(control).

This study was conducted to determine whether Pleurotus ostreatus (oyster mushroom), cultivated in various ratios with herbal extract remnants instead of cotton supplemented with nutrients (the control), improved mycelial growth, mushroom yields and longevity during storage. In addition, we investigated the transfer of medicinal herb components into the mushrooms since they contained non-specific medicinal herbs and their composition could not be controlled. Mushrooms cultivated with 70% and 100% medicinal herb remnants had faster growth rates, higher yields and less failure in the development of the fruit body than the control group. There were no differences in HPLC chromatogram among the methanol extracts of Pleurotus ostreatus in all groups. In addition, glycyrrhizin, an indicative compound of licorice which was a major herb among the herbal remnants, was not detected in any of the extracts. Pleurotus ostreatus that was cultivated with 70% and 100% herbal extract remnants had improved storage longevity in comparison with the control. They exhibited the least weight loss during storage among the groups and they maintained firmness in the stipe and pileus. However, the sources of media did not alter the color difference of the stipe and pileus or the quality index of the outward appearance during storage. In conclusion, cultivating media that contained over 70% of medicinal herb extract remnants increased the growth rates and yields of Pleurotus ostreatus. In addition, these mushrooms had enhanced storage longevity due to their firmness. Therefore, medicinal herb extract remnants should be utilized in the cultivating media of various mushrooms.

To make clear the species of Korean Asiatic cotton, 21 Asiatic cotton varieties collected from China, Manchuria, Japan and Korea and preserved at suwon Crop Experiment Station were crossed to the tester stocks and cytological studies were made for their $F_1$ pollen mother cells. The results were summarized as follows: 1. In the all $F_1$ hybrids between the 21 collections and G. herbaceum tester stocks always one ring-four association was observed. 2. In the $F_1$ hybrids between additional 5 collections and G. arboreum tester stock ring-four or chain-four was not observed. 3. In the $F_1$ hybrids between G. herbaceum tester stocks and between G. arboreum tester stocks no ring-four or chain-four was observed, while in the $F_1$ hybrids between G. herbaceum tester stock and G. arboreum tester stock always one ring-four was observed. In the $F_1$ hybrids between collections also no ring-four or chain-four was observed. 4. From above results and together with the results reported in previous paper the species of Asiatic collections was inferred to the D.U. Gerstel's G. arboreum and their race was inferred to the J. Hutcinson's G. arboreum L. race sinense.

We investigated the effect of different media components on the characteristics and productivity of Lentinula edodes cultivated in sawdust. Ten substrates were used for this study. Soybean and cotton seed meal were unsuitable substrates as fungal mycelia did not grow to maturity during the incubation period. Lentinula edodes (NIFoS culture number 2462) was grown on the ten substrates, and soybean hull, mixed medium, cotton seed hull and corn grain showed greater effect on the productivity than wheat bran. However, wheat bran induced higher productivity in NIFoS 2778 than the other substrates. Sawdust medium with soybean meal produced smaller fruiting bodies than the other substrates. In contrast, corn meal media produced larger mushrooms than the other substrates. The external characteristics of the mushrooms varied based on the substrates upon which they were grown. This is not surprising given that the substrates differed with respect to carbohydrate and protein content, e.g., cotton seed and soybean meal contained a higher crude protein and crude ash than the other substrates tested.

This experiment was conducted to find out the useful data for upland crop cultivation in the newly reclaimed tidal land. Poseung silty clay loam soil was selected, and cotton(Mogpo VII) and tall fescue were cultivated under different drainage systems and soil ameliorator applications. Soil hardness and bulk density were decreased by subsurface drainage and plastic film installed at 40cm depth of the soil. Red earth application was also effective to loosen the soil, but zeolite and gypsum made the subsoil compact. Water content of the soil was high in surface drain than that of subsurface drain or plastic film curtain plot during dry season. The water content was in order of plastic film curtain, surface drain and subsurface drain. Electrical conductivity(EC) was decreased to lower than 0.4 Simens $meter^{-1}$ ($SM^{-1}$) in the subsurface drain during rainy season, and the EC of subsurface drain was maintained a quater to an half of surface drain. The yield of cotton and tall fescue were high in order of subsurface drain, plastic film curtain and surface drain plot. The yields of cotton were increased to 36-73 % by ameliorator application, and the red earth application was more effective for tall fescue growth compare to gypsum and zeolite.
