본 실험은 표준화된 피복종자를 생산하기 위하여 피복통의 회전속도를 20, 30, 40, 45, 55, 60 rpm으로 하여 소형 피복통으로 레드클로버와 톨페스큐 종자를 피복하였다. 고형물질로는 vermiculite를 사용하였고 접착제는 polyvinyl alcohol을 사용하였다. 피복 후 통에서 회수된 단립 피복종자 무게, 서로 달라붙어 덩어리 진피복종자 무게, 피복되지 않고 회수된 미 피복물질 무게, 충격에 의한 피복층 탈락성 및 피복종자의 백립중 등을 조사하여 피복종자의 물리적 특성을 평가하였으며, 이 자료를 근거로 피복효과를 종합적으로 표현하는 피복지수를 산출하였다. 레드클로버 종자는 통의 회전속도 45 rpm에서 회수된 단립 종자 무게가 제일 높았으며(p<0.01), 덩어리진 종자 수가 적고 피복물질의 탈락율이 적었으며, 피복종자의 백립중도 가장 무거웠다. 톨페스큐 종자는 피복통 회전속도 40 rpm에서 회수된 단립 종자 무게가 제일 높았으며(p<0.01), 덩어리진 종자 수가 적고 피복물질의 탈락율이 적었으며, 피복종자의 백립중도 가장 무거웠다. 통의 회전속도별 피복지수는 레드클로버는 45 rpm에서 (p<0.01), 톨페스큐는 40 rpm에서 제일 높았다 (p<0.01). 피복통의 회전속도는 피복종자의 물리적 성질에 크게 영향을 미치기 때문에 종자피복 전에 종자나 피복제에 따른 피복통 회전속도의 표준화가 필수적이라 하겠다. Using a small pilot coating pan, red clover and tall fescue seeds were coated under different rotating speed of pan (20, 30, 40, 45, 55, 60 rpm) for standardization of seed coating. Vermiculite was used as particulate matter and polyvinyl alcohol as adhesive for the coating of seeds. Coating index was calculated based on the percent singles out, percent agglomerates out, weight of particulate matter fine, percent friability, and average weight per 100 seeds to evaluate the physical characteristics of coated seeds. The coated seed of red clover under 45 rpm rotating speed of pan, was best in terms of percent singles out, percent agglomerates out, weight of fines, and average 100 seed weight. The coated seed of tall fescue under 40 rpm rotating speed of pan, showed highest percent singles out, lowest percent agglomerates out, lowest weight of fines, and heaviest average 100 seed weight. Excellent coating results were obtained with the pan speed of 45rpm for red clover and 40 rpm for tall fescue seeds. As rotatory speed of coating pan affected much to the physical characteristics of coated seeds, standardization of the speed is required before seed coating.

Investigations were conducted into the imbibition rates of seeds, changes of seed viability after harvest, and the effects of specific gravity of seeds and high temperature treatment on germination to shorten the period of germination after seeding. Tire results are summarized as follows: 1. The lipid content of Dystaenia takesimana was 28.65% which was much higher than that of alfalfa or orchardgrass. 2. With KOH scarification imbibition rate was increased by more than two times and the optimum temperature was 20℃. 3. The percent germination was reduced gradually after harvest and rapidly after 45 days getting zero after one year. 4. The percent germination was increased by increase of the specific gravity of seeds and breeding heavier and larger seeds to improve seedling growth is suggested. 5. With high temperature treatment of the seeds at 40℃ in pregermination, the percent germination was increased from 44.3 to 91.1%. 6. It would appear that the slow germination of Dystaenia takesianana may be due to poor mobilization of seed reserves, an innate character of the seed.

To find out the factors causing the slow germination of Dystoenio takesimana, changes in the seed reserves during germination were investigated. The results obtained were as follows: 1. The carbohydrate in seeds of D. tokesimana was much exhausted due to respiration before germination and was not greatly exhausted during germination, which was different from the case of alfalfa or orchardgrass. 2. The protein content of seeds of D. takesimana increased in a linear pattern as germination progressed. 3. There was little change in the fat content of D. takesimana seeds during germination, while the fat content of alfalfa and orchardgrass seeds were greatly decreased. 4. It is suggested that slow germination of D. takesimana may be due to poor mobilization of seed reserves.

This study was designed to find out the reasons of the slow growth of Dystaenia takesimana in its early stages and ultimately to promote early growth. To study the growth characteristics of this species, the seedling growth rate, the effect of growth regulators, chlorophyll content in fresh leaves and the relationship between soil characteristics and seedling growth were examined. The results obtained are summarized as follows: 1. The root growth of Dystaenia takesimana was very poor in the early stage and the growth curve of root was quite different from that of alfalfa and orchardgrass. 2. The chlorophyll content of Dystaenia takesimana was very low in the seeding year compared with other pasture plants. 3. With the treatment of gibbereilic acid the plant height of Dystaenia takesimana was considerably promoted, however, this kind of treatment could not be a practical method at the field level. 4. The growth of Dystaenia takesimama was closely related with organic matter, boron and moisture content in the soil. 5. As the results of this study, it was suggested that t11e early growth of Dystaenia takesimana could be promoted 1) by shortening the period of germination with the high temperature treatment (40℃) of the seeds is pre-germination and 2) by the application of compost to the field, and selection for good seminal root development is important to improve establishment.

Acid phosphatase activities were analyzed in ㎍ tissue samples from an angiosperm parasite (Cuscuta cephalanthi) and its host plant (Hedera helix) by a fluorometric microtechnique. The apex and the coiling portion of the parasite axis exhibited greater enzyme activies than other portions of the hypha. Acid phosphatase activity in the haustorium was 2-3 times that in the hyphal axis. The vascular bundles of the normal host exhibited the greatest enzyme activity. The acid phosphatase activity in the host infected by the parasite decreased to the activity level of the haustorium.

종자의 priming은 유식물의 초기 정착에 중요한 기술 중의 하나이다. 따라서 본 시험에서는 목초의 주요 초종인 톨 페스큐, 오처드그라스, 알팔파 및 화이트 클로버의 발아율 향상과 균일도 증가를 위하여 priming 약제의 종류와 농도를 달리하여 발아율을 조사하였다. 본 시험은 분할구 배치법으로 주구는 KNO₃, KH₂PO₄, K₃PO₄, Ca(NO₃)₂ 및 PEG 약제를, 세구는 50 mM(또는 10%), 100 mM(또는 20%) 및 200 mM(또는 30%)의 약제농도를 두었다. Priming 목초의 발아율은 약제의 종류 및 농도에 따라 다르게 나타났다. 화본과 목초인 톨 페스큐는 Ca(NO₃)₂와 K₃PO₄가 다른 약제보다 발아율이 높았으며, 오처드그라스는 약제간에 차이가 없었으나 KH₂PO₄가 다른 약제보다 발아율이 높았다. 한편 두과목초인 알팔파와 화이트 클로버는 모두 PEG에서 높은 발아율을 나타내었다. 한편 약제의 농도는 약제의 종류에 따라 달랐다. 이상의 결과를 종합해 보면 목초의 priming은 초종에 따라 적정 약제종류와 농도가 달랐다. Seed priming is a useful technique for early establishment of seedling. In this experiment, the conditions for priming of pasture seeds (tall fescue, orchardgrass, alfalfa and white clover) have been optimized to ensure an early germination and more uniform growth of seedlings. The experiment was conducted in a split plot design with three replications. The main plots consisted of five different materials such as KNO₃, KH₂PO₄, K₃PO₄, Ca(NO₃)₂ and PEG. The subplots were consisted of three chemical concentration groups such as 50mM (or 10%), 100mM (or 20%) and 200mM (or 30%). Effect of priming materials and its concentrations were different in all four pasture seeds examined. Chemical concentration did not show any significant effects on the germination of tall fescue, however, germination of tall fescue primed with Ca(NO3)2 and K3PO4 materials were higher than the others. The concentration of prime materials did not affect on the germination of orchardgrass, but germination of orchardgrass primed with KH2PO4 was showed better result than the other materials examined. The seeds of alfalfa and white clover primed with PEG showed better germination capability than the other priming materials. In addition, chemical concentration of primed seeds also showed significant difference on the germination of alfalfa and white clover. These results suggest that seed priming induced earlier and higher germination for all four pastures tested. However, the degree of priming effectiveness on pasture species depending on the priming materials and its concentrations.
