  • 폐쇄형 묘생산 시스템을에서 기내 배양된 감자 소식물체를 이용하여 플러그묘의 생산이 시도(Kim 등, 2002)된 이래 묘소질이 우수한 감자 플러그묘를 생산하기 위한 연구가 지속되고 있다(이 등, 2002, 2003). 묘소질은 정식 후 활착의 용이, 수량 증대 및 품질의 우수성을 제공하는 잠재력으로서, 초장, 절간장, 엽형, 엽색 등과 같은 외적 소질과 광합성속도, 엽록소함량, 근활력 등 내적 소질로 구분된다(Kim, 2002). (중략)

  • 식물묘(transplant)는 육묘 후 포장에서 정식이 이루어지는 묘를 의미한다. 묘소질은 묘가 지녀야할 속성으로서 초장, 절간장, 엽색, 엽의 두께, 엽형, 괴근 형태 등은 묘의 외관과 관련된 묘소질에 해당하며, 광합성속도, 근활력, 엽록소 함량 등은 생리적 묘소질에 해당한다(Kim, 2002). 묘소질이 우수한 묘, 즉 외관이 우수하며, 병충해에 오염되지 않고, 생리 생태적 상태가 우수한 우량묘를 재배에 이용하면 정식 단계에서 활착 환경에 쉽게 적응하거나, 재배 과정에서 비료, 농약, 자재, 관리 노력 등을 적게 투입할지라도 수량이 증대되거나 품질 향상이 기대되므로 향후 우량묘에 대한 수요가 크게 증가할 것으로 예상된다(김과 박, 2002).

  • Experiments were conducted to know the effects of seed bed temperatures on the sprouting of seeds and seedling growth in the phytotron and field. Sprouting of seeds were most uniform when seed bed was stored under the straw and vinyl mulching for 48 hours after seed bed temperature increased up to 3$0^{\circ}C$ by the sun. In the phytotron, optimum temperature was 32$^{\circ}C$ for sprouting and day/night temperature of 25/30 and 20/15$^{\circ}C$ for greening and hardening of seedlings, respectively. In the field, the best results were obtained under the conditions of sprouting in the seedling chamber heated by electricity and greening the hardening under the double vinyl tunnel in the upland nusery bed.

  • Experiments were conducted to find out the optimum seeding rate and amounts of fertilizer application for seedling growth of five for machine transplanting. Number of leaves of seedlings increased as seeding rate decreased, but there was no significant differences in leaf number among fertilizer levels. At a seeding rate higher than 100g/box. number of leaves was less than 4.5, but more than five leaves were developed at a seeding rate of 50g/box.

  • Effects of growth regulators, scion length and scion diameter on shooting and seedling characteristics were investigated to increase seedling products by root cuttings of lacquer tree. Shoots developed and emerged above-ground from the root scion at 3∼5 weeks after cut plating, most of that was a shoot but some of that were 2∼3 shoots. Otherwise, non-shooting was the reason that cortical layer was decayed. Soaking in zeatin was the most effective on shooting of root cuttings and high concentration was effective. Also soaking on high contents of BA or kinetin was effective on shooting but was lower totally than soaking on zeatin. Seedling characteristics among 3 growth regulators and 3 concentrations were not any difference in statistical significant, but were move excellent than control. As root scion was tall, shoots were developed at early. 15cm length scion was the most excellent to use seedlings but 3cm length scion was wickedness. 10cm scion, however, was highest to product of seedlings than any others. 0.3∼0.5 cm length scion was showed 76% shooting rate at 10 weeks after cut planting, but seedling characteristics were not any difference among the kind of 3 diameters.

  • 접목을 실시할 때 접수와 대목의 적정한 생육은 접목을 용이하게 할 뿐만 아니라 활착 후 접목묘의 묘소질 지속에도 커다란 영향을 미칠 수 있다. 자연광 조건에서 육묘를 실시하면 묘의 생육이 불균일하여 묘소질이 일정치 않게 된다. 그러므로 인공광을 이용한 폐쇄된 환경 조건에서 육묘가 바람직하나, 대목용 박에 대한 적정 광합성 유효광량자속 또는 광주기가 제시되지 않고 있다. 본 연구의 목적은 대목용 박의 초기 생육에 미치는 광합성 유효광량자속과 광주기의 영향을 구명하는 데 있다. (중략)

  • Experiments were conducted to investigate the effects of seed bed soils and soil pH on the rice growth and control of seedling rots. A 2:1 ratio mixture of clay loam and compost resulted in the best seedling growth and quality among the soils used. At soil pH between 4 and 5. no seedling rots occurred and plant growth was normal. At soil pH above 6, seedling rots occurred and characteristics of seedings was poor. Tachiga ren application before seeding or immediately after seeding reduced seedling rots significantly at the high soil pH.

  • To utilize narrow space of vinyl house for rice seedling raising in three dimensions and raise infant seedling in large quantilies at once, shelves were constructed with few stories in inside of vinyl house and seedlings were raised by use of the shelve. Seedling characters, rice growth status on paddy field and rice grain yield were tested and the following results were obtained. Rice seedling raising was practicable to 10 days after sowing in the interval of 20cm height and 12 days, 30cm height on the shelve for seedling raising. Seedling characters, rice growth status on paddy field and rice grain yield were not varied according to the seedling raising height of the shelve. Seedling characters were not different according to irrigation intervals in raising box of rice seedling.

  • Compared with ordinary varieties, the cold resistant lines were heavy in fresh weight of seedling, low in stalk elongation. Their leaf-types were complete runner types, and they were high in wintering rate, and were abundant in the branch number and in pod numbers per branch. They were high in the seed yield.
