기상청에서 시민들에게 제공하는 봄꽃 개화일 예보서비스는 한 지점에서 장기간 수집된 기후자료와 개화일 관측자료로부터 얻은 회귀식에 의존하므로 매일의 기온변화에 따른 수정작업이 어렵고, 과거에 관측되지 않았던 기후변이에 대한 반응을 반영하지 못하며, 기상관서 이외의 지역에 대한 개화일 예보가 불가능한 단점이 있다. 이러한 단점을 보완하기 위한 방법으로 일별 기온자료만으로 구동되는 생물계절모형을 현업서비스용으로 전환하는 연구를 수행하였다. 남한지역 29개 기상대로부터 1951-1980 기간의 개나리, 진달래, 벚꽃 관측 표준목의 발아일과 개화일 관측자료 및 기온자료를 수집하여 생물계절모형의 최적모수(기준온도, 저온요구도, 고온요구도)를 추정하고 이를 반영한 개화예측모형을 작성하였다. 생물계절관측의 불확실성을 지역별 오차보정 분포도로 표현하여 생물계절모형과 결합함으로써 봄꽃 3종의 개화일 예측방법을 확립하였다. 이 방법에 의해 1971-2012 기간의 29개 지점 봄꽃 개화일을 예측한 다음 실측 개화자료와 비교한 결과 벚꽃의 경우 RMSE가 2~3일로서 실용성이 있음을 확인하였다.

Adonis multiflora is a spring ephemeral herb growing in temperate deciduous forests. To determine the flowering properties of a natural population of A. multiflora, air temperature, flowering time, and flower-falling were monitored from February 2009 to May 2011. The A. multiflora population in this study started flowering in early March and ended it in mid-April. The average flowering duration of a flower was 14.4 days in 2009 and 19.6 days in 2011. The average duration of flower-falling was between 3.4 days and 4.2 days for three years. Cumulative flowering rate (CFR) was correlated with year day (YD), year day index (YDI), and Nuttonson's index (Tn), with correlation coefficients (CC) of over 0.9 at the 1% significance level; CC value between CFR and YD was the largest and that between CFR and YDI was the smallest. However, at the 5% significance level, CFR was closely related with Tn more than any other factors. The CCs between flowering times of two years in each plant were high and significant at 1% level. The YD value of flowering time of a flower was inversely related to its flowering duration significantly for three years. In a given plant, when more flowering started early, the flowering duration was longer. The first flower blossomed on 73.4 YD in 2010 and 78.9 YD in 2011, and remained for 16.7 days in 2009 and 27.4 days in 2011, respectively; the fifth flower developed on 92.5 YD in 2010 and 96.6 YD in 2011, and remained for 8.0 days in 2009 and 14.6 days in 2011. The YD differences between the flowering times of two flowers decreased in the order of inflorescence.

When we research a landscape or make a Landscape Impact Assessment, we use the image of a specific season like summer or fall. Since there are four distinct seasons, each with a different landscape, researchers need to understand viewers′visual preferences for individual seasonal landscapes. The purpose of this study is to investigate viewers′visual preferences according to seasonal change and the respondent′s age, gender and profession. In this research, the independent variable is season: suing, summer, fall, winter and snowy winter. Three landscape types used in the experiment: forest, street and agriculture. Each landscape type has two sites for reliability. The assessment media for this research are pictures featuring landscapes taken in each of the four seasons. The study used the "paired comparison" method for taking the score of visual preference. The results of this study are as follows: 1. The summer landscape has the highest visual preference score. However, spring and fall landscapes should also be considered for visual landscape evaluation. 2. The visual preference of winter landscape covered with snow is very high, but since snow is temporal and irregular, it is difficult to consider this factor for visual landscape evaluation. 3. The visual preference score of winter is the lowest of four seasons. The attractive factors of spring are flowers, summer is greenery and fall is autumnal tints. But these are not present in winter. 4. The result of visual preferences according to age groups, gender and profession have no serious differences. 5. Visual preference to scenery of 4 seasons by age group was not different from general preference and thus was concluded to have no connection with age. 6. As a result from the research of visual preference to scenery of 4 seasons by sex, women were shown to like snow-scene more than men. This study presents an indication of general preferences of seasonal landscapes. It is expected that more advanced study will proceed after this one.

Tamarix chinenis blooms twice a you and its flowers, branches and leaves make the adjustment of tree shape. Propagation methods and growth characteristics of T. chinensis were studied in order to ascertain its potential use as one of vegetation resources for coast forestation and landscaping. The study results indicated that 1 or 2 you old hard wood cuttings showed higher rooting ratio than greenwood or semi hard wood cuttings. One to one mixture between vermiculite and pearlite appeared to be the best for bed soil, and sea sand and silt(loess) mixture was the next. Sea sand and granitic soil followed after. In terms of seasonal differences, spring cuttings showed the best rooting ratio, root number, and root length. Fall cuttings followed after spring cutting, and summer cuttings showed worst results regarding rooting ratio, root number, and root length. The best rooting promotion effects of growth regulators were observed with sea sand bed soils. There was no significant difference among growth regulators in terms of rooting and shoot growth. Low concentration below 100 ppm of growth regulators was enough for rooting promotion effect. In general, the number and mean length of roots and shoots were showed the excellent records in the sites with high rooting ratio. The study result strongly showed that T. chinensis can be considered as a suitable tree for coast forestation and landscaping because of its easy cutting propagation and rapid growth on saline lands.

The morphological and chemical characteristics of leaves and fruits were observed in the three mulberry varieties, including Daeryugppong(Morus Lhou(Ser.) koidz), Kugsang 20(Morus Lhou(Ser.) koidz) and Cataneo(Morus alba L.). The leaf development in spring was earliest in Cataneo and latest in Kugsang. Content of total nitrogen and Mg in leaf was the highest in Cataneo while that of P2O5, K and Ca in Daeryukppong. Flowers started to bloom from May 8 and in full bloom around May 15. Mature fruits began to set from June 10 to 15 and lasted by July 10 in Cataneo. Average fruit weight was heaviest in Kugsang 20(3.52 g/fruit), while lowest in Daeryukppong(1.61 g/fruit). In fruits, glucose and fructose were the major sugars. Citric acid was the most abundant organic acid in three varieties with its average content from 0.8 to 0.14%. The major pigment in fruit was anthocyanin and its content varied among varieties. The stability of anthocyanin was evaluated under various pH, temperature, and sugar concentrations. Rutin was the major flavonol glycoside present in fruits and its content varied from 0.92 to 3.36 mg/gDW. Other flavonol glycosides such as isoquercitrin and quercitrin were also detected in fruit.

The objectives of this study were to identify the period of initiation of floral primordia in black locust (Robinia pseudoacacia L.) and subsequent development of floral buds until following spring. Four mature trees of black locust located in Suwon, Korea were selected. Bud samples were collected from the current-year shoots, starting from mid June to July every week, from August to October and from February to April every month. The buds were fixed in FAA solution, dehydrated, and imbedded in paraffin for microscopic observation. Buds collected on June 16, and 23, 1997, contained primitive primordia that might be interpreted as early floral primordia. By June 30, a bud showed a positive indication of inflorescence primordium with a well-formed shoot apex. All the inflorescence primordia observed throughout the collection periods were always associated with unique hairy appendages around the primordium and enclosed within a sclerenchymatous chamber. By July 7 and 15, a floral apex had early bud scales. By July 22, primitive inflorescence developed into visible arrangement of individual floral primordial By July 29, the inflorescence developed into whirl arrangement of individual floral primordia in a transverse section, but showed little further development until October 15. The inflorescence primordia seemed to over-winter at this stage. Buds collected from February 15 and March 24 the following year also showed no further development of inflorescence primordia. By April 7 the inflorescence started to show further development with elongated axis. At this time individual flowers were easily recognized.
