Among cauliflower, ‘Snow king’ and ‘Snow crown’, which are early maturing cultivars, showed active early vegetative growth. However, ‘Snow dress’ showed good curd characteristics and in marketability, ‘Green beauty’was superior and can also be grown in Cheju. All the cauliflower and broccoli Plots transplanted on Sep. 3 and on Sep. 17 had fewer number of days from the planting date to the harvesting date than did the plots transplanted on Oct. 1. h the case of broccoli, those transplanted on Oct. 1 had the highest marketability. In the case of cauliflower cultivars, ‘Snow dress’a late maturing cultivar, demonstrated the greatest reduction in growing stage when cultivated in an unheated plastic film houses and broccoli, growing stage is similar between those grown in an open field and those grown in unheated plastic film houses. For all the cauliflower and broccoli, the contents of vitamin A and C showed no significant difference between those grown in an open field and those grown in unheated plastic film houses.

Pseudocercospora leaf spot was major disease of grape cultivar 'Campbell Early' in Korea. Leaf spot first appeared in early June and rapidly dispersed to other leaves through rainy season. Disease progress of leaf spot by Pseudocercospora vitis in plastic green house, in the two provinces (Gimje and Gimcheon), were investigated in 2007. Differences of Infected leaves (%) between cultivation systems were observed in field and plastic green house, but there was no difference between provinces. Micro environmental factors, such as temperature and relative humidity, were correlated with infected leaves by PROC REG procedure of SAS (Statistical Analysis System). As a result, regression model best described ($R^2=0.95^{**}$) the infected leaves as a function of the interaction of cumulated temperatures; Y (Infected leaves)=-7.0101+0.0496$\times$20Hcum (Cumulated hour above 20 degree)+0.0208$\times$20cum (Cumulated temperature above 20 degree)-0.2781$\times$25Hcum (Cumulated hour above 25 degree). A statistics model was shown that cumulated hour and temperature above specific degree were critical factor for Pseudocercospora leaf spot on the grapevine leaves in plastic green house.

This study was carried to select artichoke (Cynara scolymus L.) varieties that can be cultivated in non-heated greenhouse during winter in Jeju Island in Korea. Artichoke varieties namely, 'Purple Romagna' (Neseed Co.), 'Imperial Star' (Keithley Williams Seed Co.), 'Green Globe' (Park Seed Co.), 'Emerald' (Ferry-morse Seed Co.), 'Italian' (Unknown), and 'Carciofo Di Romagna' (Lortolano), were raised in a plug tray with 72 cells for two months and transplanted in a non-heated greenhouse on October 5, 2004. The first harvesting of 'Emerald' and 'Imperial Star' were the earliest and April 26 and 27, 2005 respectively. Most of the varieties were harvested from early May to June 2005. The number of head per plant was the highest in 'Green Globe' with more than five heads and the lowest were recorded in 'Italian' with one head or less. The weight of heads per plant was more than 228 g in 'Purple Romagna', 'Imperial Star' and 'Green Globe'. The highest yield was in 'Green Globe' with 2,172 kg/10a, followed by 'Imperial Star' with 1,947 kg/10a. Accordingly, it is considered that 'Green Globe' and 'Imperial Star' are adequate for the high-yield cultivation in non-heated greenhouse in Jeju Island. They can be harvested from the April to June when cultivated from the early October of the previous year.

패션프루트(Passiflora edulis)는 브라질이 원산지이며 아열대와 열대지역에서 재배되고 있는 다년생 상록덩굴식물로 시계꽃과(Passifloraceae) 시계꽃속(Passiflora)에 속한다. 전 세계적으로 500여종이 분포하고 그 중 10여종은 식용, 나머지는 관상용으로 이용되고 있다. 지구온난화로 인한 기온상승으로 전남지역 재배에 적합한 대체 아열대과수 개발이 필요하다. 패션프루트는 겨울 최저온도가 $3^{\circ}C$이상 조건에서 재배 가능하여 남부 지역는 무가온 하우스재배를 하고 있지만 시설내 6월 하순부터 8월 중순까지 $35^{\circ}C$ 이상 고온이 지속되어 과실을 볼 수 없다. 8월 하순부터 피는 꽃은 인공수분으로 착과되어 11월부터 수확이 가능하지만 이후에 낮은 온도($10^{\circ}C$이하)로 착색이 진행되지 않아서 동해피해로 수확을 포기해야 한다. 어느 시기까지 인공수분을 해야 당년에 안정적인 수확이 가능한지를 알아보고자 패션프루트의 후기(2차) 개화시기 중에서 8월 30일, 9월 10일, 9월 20일, 9월 30일에 인공수분 하여 11월 하순에 착색이 정상적으로 진행되는 처리를 조사한 결과 8월 30일 처리구만 11월 21일 착색이 되었다. 미착색과에서 내용물이 진노랑색으로 진행되면 후숙하여 상품과로 판매가 가능하기 때문에 진노랑색에 도달한 시기를 조사하였다. 조사에서 9월 10일까지 인공수분 처리한 과실은 후숙하여 상품과로 판매가 가능하였다.

In this paper, the thermal characteristics in plastic greenhouses with heating systems of electric power, hot air, and non-heating are measured and analyzed by field tests. From these tests, we were able to estimate the heating efficiency and quantitatively evaluate the characteristics of indoor thermal distributions of the particular heating system in greenhouses. The heating system of electric power was ineffective to reduce the difference of thermal distribution in the vertical direction. The hot air heating system also does not properly reduce the serious temperature fluctuation by time. By removing the above problems, these data will be utilized effectively to design better thermal environment in greenhouses.

동일부지내에 설치된 각 단동하우스에 무가온 상태 및 심야전력 전기히터, 온풍난방기를 각각 설치하여, 동절기 시설원예용 하우스의 온열환경, 난방방식별 에너지 소비특성, 난방효율에 대해서 검토하였다. 동절기 하우스의 벽체, 지붕을 통해 유출되는 관류열량을 정량적으로 계산하므로서, 하우스의 단열계획과 효율적 난방방식의 선정 및 난방에너지 절약을 유도할 수 있는 기초데이터를 제시하고자 한다. (중략)
