변색기의 수준별 야간 고온이 포도 '거봉'의 과피색 발현에 미치는 영향을 분석하기 위해 시기별 과피색 변화, 과피 내 안토시아닌 및 식물호르몬 ABA와 GA 함량을 분석하였다. 변색기 20일 동안의 야간 24, 27℃ 처리에 의해 '거봉' 포도의 과피색 불량이 나타났으며, 야간 온도가 높을수록 과피색 발현이 더욱 억제되었다. 수확기 과실 품질을 분석한 결과, 야간 21℃ 처리구에 비해 24, 27℃ 처리구의 과방중, 과립중, 당도가 감소하였다. 야간 21℃ 처리구의 과피에서 만개 후 50일부터 안토시아닌이 축적되기 시작했고, 개별 안토시아닌 중 Mal과 함께 총 안토시아닌 함량이 수확기까지 지속적으로 증가하였다. 야간 21℃ 처리구를 기준으로 과피의 총 안토시아닌이 야간 24, 27℃ 처리에 의해 감소하였으며, 개별 안토시아닌 중에서는 Peo를 제외한 나머지 안토시아닌의 감소 경향이 뚜렷하였다. 식물호르몬 ABA는 야간 21℃ 처리구의 과피에서 변색기에 최대값을 보이고 다시 수확기까지 감소하였는데, 이러한 ABA 함량의 증가는 야간 24, 27℃ 처리에 의해 감소하는 경향이었다. GA는 변색기 과피에서 급격하게 감소하여 수확기까지 낮은 함량으로 유지되었는데, 야간 기온이 낮을수록 빠르게 감소하였다. 야간 21℃ 처리구 과피에서 ABA/GA 값은 만개 후 60일에 최대값을 보이고 다시 수확기까지 감소하였지만, 이 증가 양상이 야간 고온에 의해 감소하며 과피 안토시아닌 축적과 동일한 경향을 보이며 변화하였다. 따라서 변색기 야간의 24℃ 이상의 고온은 '거봉' 포도의 과피색 발현을 억제하며, 이는 식물호르몬 ABA, GA의 비율 변화, 과실 당도 감소로 인한 총 안토시아닌 함량 및 조성 변화 때문으로 판단되었다.

The aim of the present study was to evaluate the effects of replacing 70% of the protein from fish meal by protein from ensiled or dry cassava leaves and sweet potato vines on the performance and carcass characters of growing F1 (Large White${\times}$Mong Cai) pigs in Central Vietnam. Twenty-five crossbred pigs (Large White${\times}$Mong Cai) with an initial weight of 19.7 kg (SD = 0.84) were allocated randomly to five treatment groups with 5 animals per group (3 males and 2 females). Pigs were kept individually in pens ($2.0{\times}0.8\;m$) and fed one of five diets over 90 days. The control diet was formulated with fish meal (FM) as the protein source while the other four diets were formulated by replacing 70% of fish meal protein by protein from ensiled cassava leaves (ECL), dry cassava leaves (DCL), dry sweet potato vines (DSPV) or ensiled sweet potato vines (ESPV). Animals were fed their diets at 4% of BW. Results showed that final BW, ADG, DMI and feed conversion ratio (FCR) among the experimental treatments were not significantly different (p>0.05). ECL or DCL and ESPV reduced feed cost per unit gain by 8-17.5% compared to the fish meal diet. There were no significant differences in carcass characters among the diets (p>0.05). Lean meat percentages and protein deposition ranged 41.5-45.8% and 40.2-52.9 g/d, respectively. Using ensiled or dry cassava leaves and sweet potato vine can replace at least 70% of the protein from fish meal (or 35% of total diet CP) without significant effects on performance and carcass traits of growing (20-65 kg) pigs. Including cassava leaves and sweet potato vines could improve feed cost and therefore has economic benefits.

포도에 피해를 주는 애무늬고리장님노린재에 대한 효과적인 방제약제를 선발하고 방제체계를 수립하기 위하여 몇 가지 실험을 실시하였다. 농가에서 살포한 약제들 중 애무늬고리장님노린재에 대한 방제효과를 조사한 결과 Chlorpyrifos, Parathion, Fenvalerate, Esfenvalerate.Fenitrothion 등이 효과가 있는 것으로 나타났다. 또한 포장실험에서 Fenitrothion과 Chlorpyrifos는 각각 94.8과 91.6%의 좋은 방제가를 보였다 애무늬고리장님노린재에 대한 약제처리 시기 및 방제횟수가 과실수량(평균 상품화 과방중)에 미치는 영향을 조사한 결과 잎 전개기 1회 방제구 466.0g, 꽃송이 분리기 1회 방제구 460.7, 잎 전개기 및 꽃송이 분리기 각 1치 방제구465g, 잎 전개기, 꽃송이 분리기, 그리고 착과기 각 1회 방제구 487.4g으로 무처리구 418.2g보다 높았다. 방제비용을 감안할 때 잎 전개기 1회 방제는 잎 전개기 및 꽃송이 분리기 각 1회 방제(2회 살포)보다 효과가 높았으며, 잎 전개기, 꽃송이 분리기, 그리고 착과기 각 1회 방제(3회 살포)와 큰 차이가 없었다. 따라서 포도원에서 잎 전개기(2~3엽기 =3~4엽이 보이는 시기)애무늬고리장님노린재 적기방제는 경제적으로 타당성이 있었으며, 기타 관리방안에 대하여 고찰하였다.

The complex analysis of male reproductive system of vines and fruit-tyees growing in zone of the Armenian Nuclear Power Plant (ANPP) is realized. The obtained data demonstrate that the homogeneous pollen with high fertility and optimal morphometric parameters in all variants is formed. The obtained results demonstrate that there is no one-sided effect of ANPP on the development and formation of investigated male generative system of vines and fruit trees. Thus, on the base of obtained results we can't confirm its deleterious effect on the environment.

Kiwifruit vines with broad leaves are easily torn or shed by high-speed wind. In this study, the threshold wind speed at which a cane is broken was investigated experimentally with varying physical parameters of a kiwifruit vine under two different ABL (atmospheric boundary layer) conditions. In addition, the temporal variation of wind-blown young canes was visualized using a high-speed camera. The average threshold wind speeds for ABL types A and B are about 20.5 m/s and 18.9 m/s, respectively. A wind-blown young cane takes periodic up-and-down motion when it is broken off. The mean motion frequency of young canes of the kiwifruit vines was found to be about 4.5Hz.

The present study was carried out to elucidate the effect of girdling on the quality and harvest date of the 'Shigyoku' grapes. Among girdled vines, the interval from full bloom to harvest date was 77 days; this was as much as seven days shorter in vines receiving a 20% girdling treatment. With regards to fruit characteristics, significant differences were observed in cluster length, berry number, and berry weight in vines that received girdling treatments. There were also significant differences in cluster weight; 468.2 g, 491.6 g and 504.9 g in the control group, 10% girdling group, and 20% girdling group, respectively. Thus, the use of girdling treatments is an effective approach to increasing cluster weight by 5% in the 10% girdling treatment and 8% in the 20% girdling treatment. The 10% girdling treatment showed significant difference in terms of titrable acidity; in fact, the overall titrable acidity was relatively high among all the girdling treatments. The concentration of anthocyanin increased in 20% girdling treatment, but there were no significant differences in anthocyanin concentration among girdling treatments. Berry color developed rapidly in vines that received girdling treatment.

The objective of this study is on suggesting the simulation model of 10 selected plants for the traffic noise barrier through field experiment by computer. The field experiment was carried out at the traffic noise barrier of Honam highway. The results are as follows. 1. It was identified that Paederia scandens, Celastrus Orbiculatus, Lonicera japonica, Wisteria floribunda, Parthenocissus tricuspidata and Parthenocissus quinquefolia grows well vertically and takes 3 years in covering completely. 2. It was identified that Trachelospermum asiaticum and Hedera rhombea, evergreen Climber(vine), grows slowly in comparative with other deciduous Climbers(vine), but give drivers good landscapes in winter. So those have considerable value in the south region of Taejeon. 3. It was identified that Wisteria jl.oribunda, Lonicera japonica, Paederia scandens, Clematis mandschurica and Campsis grandijlora showed good view in flowering period. 4. It was identified that auxiliary materials for inducing growth were needed in other plants except Parthenocissus tricuspidata, Parthenocissus quinquefolia. 5. It was identified that subsequent research about the auxiliary materials for inducing growth and adequate planting distance of each plants is needed for actual application.

A severe root rot of kiwifruit caused by a species of Phytophthora occurred in 1-to 5-year-old vines at the south coast region of Korea in 1997. Infected vines exhibited leaf chlorosis, scorch and defoliation, root and stem rot, and eventual death. The disease was relatively severe in poorly drained lowlands, of which 19 out of 23 fields were damaged by the disease. Meanwhile, only one among 58 upland fields was infected by the disease. Incidence of infected vines reached over 80% in heavily damaged fields and a species of Phytophthora was isolated from inner tissues of roots, stems, and rhizosphere soils of the plants. The causal pathogen was identified as P. drechsleri based on its mycological characteristics. Pathogenicity of the fungus was confirmed by artificial inoculation to seedlings of kiwifruit 'Hayward'. The pathogen was re-isolated from the inoculated plants showing symptoms similar to those observed in the fields. Root rot of kiwifruit caused by P. drechsleri has not been reported previously in Korea.
