삽목시기가 진달래의 발근에 미치는 영향을 알아보기 위하여 시기별로 삽목하여 본 결과 5월부터 6월에 걸쳐서 비교적 높은 발근율을 얻을 수 있었는데, 6월 12일에 실시한 삽목에서 92.5%의 발근율을 나타내었다. 그러나 생식생장이 시작되는 7월 이후에는 발근율이 현저하게 낮아졌다. 즉 진달래의 삽목 최적기는 6월 중순으로 판단되었다. 관행 녹지삽목(greenwood straight cutting)과 녹 종삼목(踵揷木)(greenwood heel cutting)간에는 발근율에 있어서 별 차이를 보이지 않았다. 5월 15일에 실시한 숙지삽 결과 45%의 발근율을 보였으며, 6월 12일에 흰진달래를 삽목하였을 때에도 85%의 발근율을 나타내었다. NAA, lBA 및 Rootone 의 처리효과 실험에서 일반적으로 $200mg{\cdot}L^{-1}$의 저농도에서 12시간 동안 처리하는 것에 비하여, 고농도($2,000mg{\cdot}L^{-1}$) 에서 수초간 처리하는 것이 발근촉진효과가 좋았는데, NAA $2,000mg{\cdot}L^1$에서 15초간 침지처리하는 것이 가장 효과적이었다.

적심 및 rootone 처리가 고추 10품종의 발근력에 미치는 영향을 조사한 결과, 모두 정상적으로 발근되었으나 품종간에 큰 차이를 보였다. 즉 'Gukbo'와 'Chungyang' 등은 발근력이 낮은 반면, 대목 이용 가능성이 높은 'Geumsang' 등은 매우 높았다. 발근촉진제 rootone 처리는 모든 품종의 발근을 현저히 증가시켜 높은 실용성을 보여주었다. 또한 적심에 따른 발근 지연 현상은 rootone 처리로 거의 완벽하게 보완될 수 있었다. 선발된 대목 10품종과 접수 3품종을 적심과 IBA 단용 또는 병행처리 후 발근력을 검토한 결과, 대목 중에서는 'Tantan'이 가장 높았고, 'Konesian Hot'과 'Wonkwang 1호'도 높았다. 또한 공시된 10개 대목은 대면적에 일반재배 되는 품종인 'Manita', 'Chungyang', 'Nokkwang'보다 발근력이 높았다. IBA 처리는 발근력을 다소 향상시켰으나 rootone 처리에 비해 효과가 뚜렷하지 않았다.

The seedlings of yacon (Polymnia sonchifolia Poeppig ＆ Endlicher), which were cuttings, plug seedling (PS), crown bud before sprouting (CBBS), crown bud after sprouting (CBAS), and divided seedling after budding (DSAB) were planted at 70$\times$50 cm planting distance on ridge; that was interow spacingintrarow spacing, and about 28,500$\pm$71 plants/ha. CBBS didn't need work and equipment to raise seedlings. PS and DSAB grew taller to 140.5 and 143.3cm, respectively, than others at 150 days after planting. In the changes of plant height, PS and DSAB showed taller than others during growth period, cuttings, CBBS, and CBAS grew rapidly in middle growth stage. Excepting main stem and petiole length, other characters were significant for seedling. Fresh weights were different among seedlings. Even though the yield of plants grown from CBAS and CBBS were lower with 34.7 and 36.4 ton/ha, respectively, than 3.6 ton/ha of DSAB; its yield index were over 95%, hence, those of plants grown from cutting and PS were lower with 73 and 87%, respectively. The ratio of tuberous roots over 200g to total tuberous roots per plant was the highest from DSAB. Most of tuberous roots were under 200g per tuberous root from cuttings. CBBS, CBAS, and DSAB are suitable to use seedlings for high yield of yacono. Yacon plant by DSAB much produced tuberous root of over 200g.

무궁화 (Hibiscus syriacus 'Honghwarang')의 휴면특성을 구명하고자 온도와 생장조절물질을 처리하여 맹아(萌芽) 차이를 비교하였다. 맹아는 온도가 높을수록 빨랐으며($10{\sim}30^{\circ}C$), $30^{\circ}C$ 무처리구는 삽목 후 4일만에 맹아하기 시작하여 6일경에는 100% 맹아했다. GA와 BA처리도 대조구인 무처리와 큰 차이 없이 $20^{\circ}C$ 이상의 온도에서는 6일만에 맹아하여 62.5%의 높은 맹아율을 나타내었다. ABA 침지처리는 $25^{\circ}C$이하의 온도에서는 맹아율이 저조하였으나, $25^{\circ}C$이상의 온도에서는 삽목 6일 후에 맹아하기 시작하여 12일 후에 93% 맹아되어, 고온 조건에서는 생장억제제인 ABA처리가 맹아억제에 전혀 효과가 없었다.

To do mass multiplication of plug seedlings in potatoes, apical stem cuttings originated from virus-free microtubers were cut to one-two internodes and transplanted into the plug-tray. After 10days, we applied Chitosan and Wood Extraction on rooting and tuber formation of plug seedlings. To improve field adaptability of plug seedlings, rooted cuttings with a height of 20cm after 20days of cutting were transplanted ito the fields, We applied 500~2000ppm Chitosan on growth characteristics and tuber formation of that. The above and underground growths, such as plant height and number of leaves were significantly more vigorous after treatment with 500~1,000ppm Chitosan and 2,000ppm Wood Extraction, the spray treatment was carried out five times at intervals of four days after ten days of transplanting. T-N, K, P, Mg and Na, were higher as the concentrations of chitosan and Wood Extraction were higher. The growth and tuber yield in plug seedlings planting plot and seed potatoes planting plot were effectively highter as foliar application of Chitosan(500~2,000ppm) was done after planting the plot. T-N content in leaves and tuber was higher as the concentration of Chitosan was high. A similar tendency was shown in K, P and Mg. In the small tuber(under 30g), the number of tubers and tuber yield were relatively increased in the seed potatoes planting plot, but the large tubers(over 80g) yield was higher in the plug seedlings planting plot, and in order to increase tuber yield in plug seedlings it was necessary to add plant density to the field.

For the mass production of plug seedlings in cultivar ‘Dejima’ potato (Solanum tuberosum L.) the optimal apical cutting diameter for rooting and rapid multiplication of stem cuttings in hydroponics were determined. In addition, the best planting date was predicted to increase tuber yield of plug seedlings at fall cropping in Cheju-Do, Korea. Days to initial rooting decreased as the cutting diameter was reduced. Plant height, leaf number, root length and root weight per plant were favorable as the cutting diameter was small. The ideal cutting diameter was 1-2 mm in this experiment. In the hydroponic cultures, the Japanese standard (JS) nutrient solution was the most effective for multiplication of stem cuttings. It was able to propagate more than 20 times a month from a single mother plant. Viability of plants, which were derived from plug seedlings using stem cuttings, was excellent when transplanted to the field. The number of tubers and tuber yield in both of the plug seedlings and seed potato planting plots were high when planted on 25 August. The number and yield were reduced when planted on 15 August, 5 September and 15 September. The degree of decrease of tuber yield in the plug seedling planting plot however, was lower than that of seed potatoes when the planting date was late. In the case of small tubers (under 30 g), the number of tubers and tuber yield were evidently increased in the seed potato tuber planting plot; the yield of large tuber (over 80g) in the plug seedling planting plot was higher than that of the seed potato. The total tuber yield per plant in the plug seedling planting plot was less than that of the seed potato; therefore, in order to increase tuber yield it was necessary to increase field plant density.

방울토마토 잠액 수경재배에 육묘단계를 생략한 재배기술을 확립하기 위하여 ‘Pico’, ‘Pepe’ 및 ‘Koko’ 3품종의 측지를 육묘상에서 15일간 육묘한 것과 양액 재배상에 바로 정식하고 양액의 농도를 표준과 50% 농도의 2수준으로 처리하여 생육상태와 수량을 조사하였다. 1. 직접정식이 육묘정식보다 초기 생육단계에서 초장이 길었고, 엽수가 많았으며 엽면적이 넓었다. 수확시기는 직접정식이 육묘정식보다 6일 정도 빨랐고 품종간에는 ‘Pepe’가 다른 2품종보다 빨랐으며 양액 농도간에는 차이가 없었다. 2. 과일 1개당 평균 무게는 정식묘가 양액의 농도에 따른 영향은 없었고 품종간에는 ‘Pepe’가 적었다. 그리고 수량은 표준농도의 양액에 직접 정식한 ‘Pepe’에서 가장 많았다. 3. 과즙의 당도는 직접 정식한 구가 육묘 정식한 구보다 높았고 품종간에는 ‘Pepe’가 높았다.

본 실험은 왜화제인 daminozide, chlormequat, hexaconazole, uniconazole, paclobutrazole과 triazole계 살균제인 diniconazole, myclobutanil, difenoconazole, tebuconazole, bitertanol 등이 'New Guinea' 임파첸스의 삽수발근에 미치는 영향을 조사하기 위하여 수행하였다. 왜화제 처리에 의한 부정근의 형성은 'Papete'와 'Anguilla'에서 daminozide를 제외한 모든 약제에서 촉진되었으며 hexaconazole, uniconazole과 paclobutrazole 처리에서 chlormequat보다 더 많은 부정근이 형성되었다. 최장근의 길이와 근권은 'Papete'에서 chlormequat, hexaconazole, uniconazole 및 pac1obutrazol의 비교적 높은 농도에서 감소되었으나 'Anguilla' 품종에서는 차이가 적었다. 한편, triazole계 살균제처리에 의한 부정근의 형성은 'Papete'와 'Martinique' 품종에서 현저하게 촉진되었으며 'Pagopago'에서는 큰 영향이 없었다. 최장근의 길이와 근권은 'Martinique'와 'Pagopago'에서 'Papete'에 비하여 민감한 반응을 보였다. 이와 같은 결과들은 발근촉진을 위하여 triazole계 살균제들이 효과적으로 사용될 수 있다는 것을 제시한다.

The study was conducted to investigate the effect of rootstock on growth and early yield of stenting-propagated cut roses (Rosa hybrida Hort.) 'Pink Aurora' and 'Yellow King'. The scions, prepared as single-node cuttings, each with a five-leaflet leaf, were grafted onto cuttings of Rosa indica 'Major', Rosa multiflora 'Chille Wonye No. 1', Rosa multiflora 'K-1', or Rosa multiflora 'Burr' as the rootstock. The rootstock cuttings were removed of all leaves and buds before grafting. The base of scion and the top of rootstock were held together and simultaneously cut at a $45^{\circ}$ angle for ease of grafting. Scion-rootstock unions were stuck in rockwool cubes and placed on a misted glasshouse bench for rooting before being transplanted into a rockwool slabs for cultivation. Rooting was the greatest in the 'Pink Aurora' and 'Yellow King' grafted on the rootstock Rosa indica 'Major'. In 'Pink Aurora', stem length, stem diameter, five-leaflet leaves per stem, and stem fresh weight of the harvested cut flowers were not affected by the rootstock. The greatest total yield of 'Pink Aurora' was obtained in plants grafted onto the Rosa indica 'Major' rootstock. Overall growth of 'Yellow King' was the greatest in plants grafted onto Rosa multiflora 'Burr' rootstock, although total yield was not affected by the rootstock. These results suggest that Rosa indica 'Major' is the most effective rootstock not only for rooting, but also for early yield and growth for stenting propagation of these cut roses.
