This study was conducted to examine the growth and physiological characteristics of Polystichum lepidocaulon native fern as affected by soil mixture as an environment modeled on habitate where was sunken-condition. 1. Polystichum lepidocaulon grew well sunken more than non-sunken condition. Under soil mixture of field soil : sand : leaf mold, Plant height, frond width, frond length, stipe length and ornamental value were increased compared with the other soil mixture. 2. Fresh and dry weight of fronds were higher with non-sunken than sunken condition. In sunken condition, fresh and dry weight were better with field soil : sand : leaf mold than the other soil mixture. 3. Number of spore fronds were increased with sunken condition. As sunken condition, sand : leaf mold was better than field soil : sand : leaf mold or leaf mold. 4. Photosynthetic rate, $CO_2$ absorption rate and water efficiency were higher with field soil : sand : leaf mold than that of sand : leaf mold or leaf mold. expect of stomatal conduction and $CO_2$ use efficiency.

This study was conducted to find out the optimum ranges of soil physical properties for wasabi growth by the relationship of soil physical properties and plant growth. Soil bulk density and hardness were higher in decomposition of granite and river sand than hydroball. This root distribution of surface layer was higher in decomposition of granite and river sand than hydroball. Growth characteristics and yield were higher in hydroball than decomposition of granite and river sand. In inlet site, the marketable rhizome weight in decompasition of granite, river sand, hydroball were 298kg/10a, 401kg/10a, 766kg/10a, respectively. But outlet, the weight in three soils were 251kg/10a, 256kg/10a, 633kg/10a, respectively.

물 고추냉이는 십자화과의 숙근성 다년생 초본식물로서 일본과 대만 등에서 재배되며 세계 여러 나라에서 식품, 가공원료, 향신료, 의약소재 등으로 이용되고 있다. 우리나라에서는 철원과 무주 등에서 재배되고 있으나 재배환경 및 기술의 한계로 규모와 생산량은 매우 저조한 실정이다. 따라서 본 연구는 물 고추냉이 순환 베드시스템 개발을 위한 기초연구로 수행되었다. 마사토의 높이와 고랑의 유무에 따라 3개 베드 (A-마사토 높이 4.0cm, 고랑 있음, B-마사토 높이 5.5cm, 고랑 있음, C-마사토 높이 7.0cm, 고랑 없음)로 시험하였다. 물 고추냉이의 생장량과 식물체 내의 양분 분석(질소, 인산, 칼륨)을 분석하였다. 그 결과 베드 높이가 가장 낮고(4cm) 고랑이 있는 베드에서 생장량이 가장 우수하였고 마사토 높이가 가장 높은(7cm) 처리구보다 생장량이 2배 이상 증가하였다. 전체적으로 엽장보다 엽폭이 길었고 심장형 잎의 특성을 그대로 나타내었다. 식물체 내의 양분 분석 결과 처리구 별로 질소, 인산, 칼륨의 함량 차이가 크게 나타났다. A 베드에서 질소 4,150, 인산 500, 칼륨 1,500ppm 에 비하여 C 베드는 질소 730, 인산 120, 칼륨 700ppm 정도로 낮았다. 대조구의 동일 지역, 동일 기간의 계류지 하우스재배(데이터 미발표)에 비해 순환식 베드 재배가 우수하였고, 특히 A 베드에서 가장 우수하여 절수, 2단 재배 등의 예상되는 효과를 감안할 때 물 고추냉이 순환식 베드 재배의 가능성이 충분하다고 판단된다.

To select the most proper soil for root initiation from stem cuts of Birdsfoot trefoil (Lotus corniculatus L.), eight-week-old stem cuts were cultured on three types of soil [commercial bed soil, decomposed granite (DCG), and river sand] for one month. The results showed that the root initiation ratios on DCG (77.8%) and river sand (70.0%) were relatively high, but the ratio on commercial bed soil (41.1%) was very low. To examine the effect of rare earth (RE) and Indole-3-Butyric Acid (IBA) on root initiation from stem cuts of Birdsfoot Trefoil, stem cuts were cultured on two types of soil (DCG and river sand) with treatment of RE and IBA for one month. The root initiation ratios turned out to be 90.0% (DCG with 60 ppm of RE), 80.0% (river sand with 20 ppm of RE), 96.7% (DCG with 40 ppm of IBA), and 96.7% (river sand with 40 ppm of IBA). These results suggested that the most efficient way for root initiation of Birdsfoot trefoil was to culture the stem cuts on river sand or DCG over 30 days with IBA treatment (40 ppm).

This study examined basic mechanical properties by developing eco-friendly soil concrete using Masato particulate matter treated as waste. Experiments show that DG10 satisfies the compressive strength criterion, but for DG20, the criterion was not reached. As the mixing volume of Masato particulates increased, the compressive strength and slump decreased, and in the case of the compression strength test after freezing and melting, it was found that the standards were not met.

This study is focused on the cultivation of seedlings and cuttings of roundleaf chastetree(Vitex rotundifolia L. f.) according to the sorts of soil and fertilization methods. The results are summarized as follows: When roundleaf chastetree seedlings(aged 1-0) and cuttings(aged 1-0) were cultivated in three different kinds of soil- sand, granite soil, and yellow silt- without any fertilization, 70% of the seedlings survived in sand and granite soil, and 35% did in yellow silt; 90% of the cuttings survived in granite soil and 80% did in sand and yellow silt. The general growth of both seedlings and cuttings was good in granite soil, and sand but relatively inferior in yellow silt. Seedlings showed good stem growth while cuttings had fine root growth. In case of cultivation of seedlings with different kinds and quantities of fertilizer adjusted and with granite soil as basic soil, seedlings and cuttings survived in the experimental section where only the organic fertilizer was used as basic fertilization; in contrast, seedlings grown in the experimental section were all dead where both inorganic and liquefied fertilizer were used. Cuttings showed considerably higher survival rates than seedlings at the experimental fertilization section; particularly, the survival rate of cuttings was twice as much as that of seedlings at the experimental section with low fertilization. This study results revealed that cuttings are desirable than seedlings in general rootage, growth, adaptability to soil, and cuttings have lower demand for soil fertility in time of growing roundleaf chastetree saplings.

본 연구는 응달고사리[Cornopteris crenulatoserrulata (Makino) Nakai]의 전엽체 대량증식 및 포자체 형성을 위한 배지구성물질 및 배양토의 최적조건을 구명하고자 수행되었다. 실험재료는 기내에서 포자발아를 통해 획득한 전엽체를 계대배양하여 실험에 사용하였다. 배지구성물질이 전엽체의 증식 및 형태 형성에 미치는 영향을 알아보고자, 배지구성물질의 농도를 1/4, 1/2, 1배로 조절한 MS배지와 Knop배지를 조성하였다. 기내 배양된 전엽체 300mg을 메스로 다진 후 상기 5종의 배지에 배양하였다. 실험의 결과, 전엽체의 생체중은 Knop배지에서 3.93g으로 가장 많이 증가되었으며, 현미경으로 관찰한 결과 기관형성도 정상적으로 이루어졌다. 선행연구에서 선발된 Knop배지를 기준으로 sucrose(0, 0.5, 1.0, 2.0 및 3.0%) 및 활성탄(0, 0.1, 0.2 및 0.4%)의 농도를 달리 첨가하여 전엽체에 미치는 영향을 확인하였다. 실험결과, 0.5%의 sucrose를 첨가한 배지에서 생체중이 5.90g으로 증가하였으며, 활성탄은 첨가하지 않는 것이 효과적이었다. 포자체 형성을 위한 최적의 토양조건을 구명하고자, 원예상토와 피트모스, 펄라이트, 마사토 등 인공토양의 비율을 달리하여 8종류의 토양을 사각분에 충진하였으며, 기내에서 배양된 전엽체를 10초간 분쇄한 후 사각분에 1g씩 균일하게 분주하여 16주간 배양하였다. 배양결과, 원예상토를 단용으로 처리한 실험구에서 포자체가 171.5개로 가장 많이 발생하였으며, 원예상토와 마사토를 2:1(v:v)로 혼합한 토양에서 125.0개, 원예상토, 피트모스, 마사토를 1:1:1(v:v:v)로 혼합한 토양에서 113.3개 순으로 포자체가 발생하였다. 포자체의 생육은 포자체의 형성이 가장 많았던 원예상토를 단용한 토양에 비해 원예상토와 마사토를 2:1(v:v)로 혼합한 토양에서 생체중, 엽장, 엽폭, 근장 등이 우수하였다. 한편 피트모스가 혼합된 토양에서는 전엽체와 포자체 형성이 억제되는 경향을 보였다. 위 결과로 보아 응달고사리의 전엽체 기내배양에는 sucrose 0.5%가 첨가된 Knop배지가 적합하며, 포자체 대량생산을 위해서는 원예상토를 단용한 토양을 사용하는 것이 좋다고 판단되었다.

This study was conducted to investigate the optimal conditions for spore germination, prothallus propagation, sporophyte formation and seedling growth in Microlepia strigosa (Thunb.) C. Presl. Spore germination and prothallus development were promoted by low concentrations of Knop medium nutrient solution. The optimal medium for prothallus propagation and antheridium formation was 2X MS medium with 3% sucrose. The activated charcoal content of the medium did not affect prothallus proliferation. Among the various combinations of culture soil (bedding soil, peat moss, perlite and decomposed granite), a mixture of bedding soil, peat moss and decomposed granite at a ratio of 1 : 1 : 1 (v : v : v) had a positive effect on sporophyte formation. The most efficient conditions for promoting the growth of whole plants (sporophyte seedlings) were 50 - cell plug trays filled with a mixture of bedding soil and decomposed granite at a 2 : 1 (v : v) ratio.
