고추 유모의 초기 생육에 미치는 미량원소 엽면시비제의 효과를 검정하기 위하여 사포닌과 EVA를 각각 1000㎖·ℓ^-1와 3000㎖·ℓ^-1의 농도로 처리하여 그 결과를 조사하였다. 고추 유모의 초장, 엽수, 경경 그리고 엽면적에 미치는 두 가지 엽면시비제의 생육촉진효과는 처리 제제와 처리 농도에 따라 일정한 경향을 나타내지는 않았다. 그런데, 사포닌 3000㎖·ℓ^-1처리에서는 대조구에 비해서 시간이 경과함에 따라서 초장과 경경에서 약간의 증가 경향을 나타내어 생육촉진효과의 가능성을 시사하였다. EVA는 일시적이기는 하지만 엽면적을 증가시키는 결과를 나타내었으며, 1000㎖·ℓ^-1보다는 3000㎖·ℓ^-1에서 더 높았다. 본 실험에서의 미량원소의 엽면시비는 단기간의 초기생육에서의 결과이므로 그 효과를 속단할 수는 없으나, 정밀한 시비 관리가 어려운 토양재배나 일시적인 생육촉진 효과에는 유용하게 이용될 수 있을 것으로 생각된다. Two kinds of foliar fertilizers of microelements, Saponin and EVA, were examined for check up the effect of growth promotion in hot pepper seedling. There were no significant effects of foliar fertilization of microelement nutrients on plant height, leaf number, stem diameter and leaf area in hot pepper. But, there were some increases of plant height and stem diameter with Saponin 3000㎖·ℓ^-1 treatment than control. Also, there were increases of leaf area with increasing concentration of EVA. It was confirmed that foliar fertilization of microelement nutrients may improve the growth of hot pepper seedlings.

The study was conducted to find out the effects of slow-released fertilizer(SRF) on the growth and yield of soybeans and in the soil. The plant height of soybeans was showed the higher in the SRF than in urea at early growth stage, but that showed the very similar results in both of SRF and urea at late growth stage. The chlorophyll content and photosynthetic activity of soybeans were higher in the SRF than in urea at 40days after sowing. Grain yield was not significantly different between in the SRF and in urea. Total nitrogen content in the grain and shoot of soybeans was showed higher in the SRF than urea. Nitrogen uptake in the grains of soybeans was similar results in both of the SRF and urea, but that of SRF in the shoot was higher than in urea. Efficiency of nitrogen in the SRF of soybeans was higher than in urea by 13.1%. Nitrogen content in the soil after experiment of SRF was lower than in urea.

토마토를 이용하여 미량원소 엽면시비제인 Saponin과 EVA를 각각 1000㎖·ℓ^-1와 3000㎖·ℓ^-1의 농도로 처리하여, 생육초기에 미치는 효과를 조사하였다. 토마토의 초장, 엽수, 경경 그리고 엽면적에 미치는 엽면 시비제의 생육촉진효과의 일정한 경향을 관찰할 수는 없었지만, 생육단계에 따라서 일부 처리에 있어서는 엽면시비에 의한 수치의 증가를 관찰할 수 있었다. 그러나, 각각의 조사항목에 대한 수치의 변화는 서로 연관성이 있을 것으로 생각되며, 이러한 수치의 변화는 미량요소에 의한 효과인지 아니면 성분표시가 되어있지 않은 식물생장조절물질 같은 성분의 효과인지에 대해서는 앞으로도 계속적인 실험을 통하여 확인할 필요가 있을 것으로 생각되었다. 본 실험의 결과에서 생산자의 무분별한 엽면시비제의 사용은 그 효능과 효과에 의문을 제기할 수 있는 가능성이 충분히 있을 수 있으므로, 그 사용에 있어서는 작물에 따라서 성분, 사용량, 사용방법을 충분히 파악하여 사용하는 것이 경제적일 뿐만 아니라 작물생육을 위해서도 유익할 것으로 생각되었다. This study was conducted to investigate the effects of foliar application of microelements on the earlier growth of table variety tomato. There were no significant effects of foliar application on plant height, leaf number, stem diameter, leaf area in tomato, but it seemed that there were some possibility for growth promote effect in leaf number and leaf area by foliar spray of EVA 1000㎖·ℓ^-1 and Saponin 1000㎖·ℓ^-1 treatment at some growth stages. Foliar spray of microelements may have some efficient effects for plant growth or differentiation, they have to confirmed the optimum concentration, treatment times and components with plants.

This study was conducted to investigate the effects of fertigation and foliar spray with liquid organic nutrients on the early growth of hot pepper seedlings. The foliar spray of liquid organic nutrients with l000㎖ · ℓ^(-1)was effective on the increase of plant height, number of leaves, stem diameter and leaf area of hot pepper seedling. The spray of liquid organic nutrients with 500㎖ · ℓ^(-1) was only effective on the increase of number of leaves of hot peppers. But the fertigations of liquid organic nutrients with 1000㎖ · ℓ^(-1)and 2000㎖ · ℓ^(-1) increased partly to plant height and leaf area of hot pepper seedlings. It was confirmed that foliar application of liquid organic nutrients containing chitosan and wood vinegar could improve the early growth of hot pepper seedlings

In order to examine how growth substances influence to fruit growth and its quality, we cultivated 3 different kinds of melons which grown in hydroponic system into 3 different types of growth substances, such as perlite, perlite/rock wool and rock wool/perlite. In this experiment, “Siroi Kagayaki”, showed no significant difference in fruit weight and its diameter in any of growth substances, but higher in plant height in perlite/rock wool than Perlite. In case of “TS-1806”, there were no significant differences in soluble solids, fruit weight and diameter in all the substances. However, it showed longer in fruit length in rock wool / perlite than that in perlite/ rock wool. In addition, the soluble solids in placenta and flesh were higher in perlite than those in rock wool/perlite.

A new circulating hydroponic system was invented for oriental melons grown in the greenhouse. Fordeveloping nutrient solution management techniques, we examined the changes of nutrient contents ofcirculating solution in three different types of new hydroponic systems. The yield and fruit quality oforiental melons in hydroponics were better than those in soil culture. The substrate culture wasappropriate for hydroponics of oriental melons, and NFT was turned to be the opposite due to thephysiological disorder during hot seasons. Yamazaki's melon solution with EC 2.0 dSm-1 was themost appropriate for oriental melons. The new circulating hydroponic system seemed to be appropri-ate for oriental melons because of the stable EC, pH and the macro- and micro-element contents.NO3-N, Ca and Mg contents in the circulating solution kept a good balance in all types of hydropon-ics. However, P content, compared to other types, decreased by the degree of 1 me L-1 in perlitemedium. K content showed irregular status in perlite but showed the stable status in cocopeat. Gen-erally, microelements, except Mo, showed stable absorption in the substrate culture. However, in NFT,most of the elements showed irregular absorption except B and Mn. Microelement absorption, espe-cially Cu, Zn and Mo, decreased during hot seasons.

This study was conducted to investigate the relationships between the responses of soybean and red pepper to simulated acid rain, the simulated acid rain(SAR) of pH 1.8, 2.3 and normal rain of pH 6.0 applied from 30 days after emergence of soybean and red pepper to harvest at the two-week interval. SAR of pH 1.8 and 2.3 caused brown spots in the Ieaves of soybean and red pepper and the injured rates were severe as the pH of SAR lowered. Chlorophyll content of soybean and red pepper decreased as the pH of SAR lowered. Visual injured rate affected by simulated acid rain treated 3 times were negatively correlated with chlorophyll content of soybean and red pepper.

There are various limiting factors that take part in the production of daughter plants, but the importantthing for mother plants of strawberries is to undergo a sufficient period of dormancy during winter. It is a well knownfact that many runners and daughter plants are generated from mother plants that have been through sufficient coldtreatment, but such researches were not found in Korea. This experiment was conducted due to the recent need for aresearch on the effects of cold treatment using ‘Seolhyang,’ ‘Maehyang’ and ‘Ssanta’ cultivars bred in Korea for twoyears in 2012 and 2013. The strawberries were divided into 4 types treatments: cold treatment plants in which 1,000hours have passed in the temperature of 5oC and below; cold+heated treatment plants in which 1,000 hours havepassed in the temperature of 5oC and below, and then 2 weeks in the greenhouse; greenhouse treatment plants raisedin the greenhouse; and plants in harvest treatment. The results of the 2012 experiment showed that ‘Seolhyang’ hadthe bigger number of daughter plants in the cold, cold+heated, and harvest than greenhouse. ‘Maehyang’ had the biggestnumber of daughter plants in the cold+heated , and lowest in the greenhouse and harvest. ‘Ssanta’ had no significantdifference in all treatments. The results of the 2013 experiment showed that ‘Seolhyang’ and ‘Maehyang’ bothhad more daughter plants in cold and cold+heated than in the greenhouse and harvest. ‘Ssanta’ tended to show a similarresult and cold+heated had statistically more daughter plants than greenhouse 딸기재배에서는 육묘가 차지하는 비중이 크다. 육묘의제일 첫 단계는 모주의 관리부터 시작되는데, 재배농가에서는 가능한 한 건강한 다수의 자묘를 확보하는데 노력을 기울인다. 자묘의 발생에 관여하는 제한요인은 여러 가지가 있지만, 딸기의 모주는 겨울 동안 충분한 휴면을 하는 것이 중요하다. 충분한 저온을 경과한 모주에서 많은 런너와 자묘가 발생한다는 사실은 알려져 있지만 국내에서의 연구결과는 전혀 볼 수가 없다. 최근에국내에서 육성된 품종을 이용한 딸기 모주의 저온경과의효과에 대한 연구가 필요하여 본 실험을 실시하였다. 국내 육성 품종인 ‘설향’, ‘매향’, ‘싼타’ 딸기를 이용하여2012년과 2013년 2년간 반복하여 실험을 하였다. 모주의 온도처리는 5oC 이하에서 1,000시간 이상 경과한 저온 처리 묘(이하 저온처리묘), 5oC 이하에서 1,000시간이상 경과 시킨 후 온상에서 2주간 보온한 저온+보온처리 묘(이하 저온+보온처리 묘), 겨울 동안 온상에서 보관된 온상 묘, 봄철까지 수확을 진행 한 재배 묘의 4가지처리구로 구분하였다. 2012년의 실험 결과에서는, ‘설향’품종은 저온, 저온+보온 처리구 그리고 재배 처리구에서자묘수가 많았고, 온상 처리구에서 유의하게 적었다. ‘매향’은 저온+보온 처리구가 월등하게 자묘가 많았고, 온상 처리구와 재배 처리구는 유의하게 적었다. ‘싼타’는모든 처리구에서 유의한 차이가 없었다. 2013년의 실험결과에서는 ‘설향’과 ‘매향’ 품종은 저온 처리구와 저온+가온 처리구가 온상 처리구와 재배 처리구 보다 자묘발생이 통계적으로 유의하게 많았다. ‘싼타’도 비슷한 경향을 나타내었는데, 저온+보온 처리구는 온상 처리구보다 통계적으로 유의하게 자묘수가 많았다. 본 실험의 결과에서 실험년도와 품종 간에 차이는 있었지만 모주를겨울동안 충분하게 저온을 거치도록 하는 것이 자묘 발생에 유리한 것으로 판단되었다.
