초록

본 논문에서는 생분해성 종이포트를 이용한 오이 접목묘 육묘시 추비용 양액의 농도와 육묘일수, 정식 후 야간 온도에 따른 오이의 생육을 검토하였다. 오이 종이포트묘 접목활착 종료 후 육묘 중 시비 농도를 0.5S(EC $0.8dS{\cdot}m^{-1}$), 1.0S(EC $1.6dS{\cdot}m^{-1}$), 2.0S(EC $3.2dS{\cdot}m^{-1}$)의 3수준으로 처리한 뒤, 육묘일수를 파종 후 26, 33, 40, 47일로 달리하여 정식하였다. 정식 직후 야간 온도를 10, 15, $25^{\circ}C$ 3수준으로 조합, 처리하여 10일 동안 재배하였다. 육묘기간 중 오이 종이포트묘의 초장, 엽수, 엽면적, 건물중, 및 상대생장률은 추비용 양액의 농도가 높아질수록 증가하였으며, 육묘일수가 경과할수록 처리에 따른 차이는 더 커졌다. 건물률은 육묘일수가 경과함에 따라 증가하는 경향을 보였으나, 양액의 농도가 높을수록 낮았다. 반면 비엽면적은 육묘일수가 길어질수록 감소하였고, 양액 농도가 높을수록 높은 값을 나타냈다. 정식 10일 후 오이의 생육은 육묘일수가 증가할수록 초장, 엽면적, 건물중에 있어서 높은 값을 나타냈으나, 상대생장률은 감소하였다. 육묘일수 26일, 30일의 경우 정식 후 오이의 생육은 야간 온도의 영향이 크지 않았으나, 육묘일수가 길어져 40일이상 육묘한 묘는 정식 후 $10^{\circ}C$ 정도의 저온에서 활착이 지연되어 생육이 저조하였다. 따라서 오이 종이포트 접목묘 생산시 추비용 양액농도 1S, 육묘일수는 30일 내외가 추천되며, 정식 후 활착 및 생육 촉진을 위해 $15-25^{\circ}C$ 범위의 야간온도 관리가 요구된다.

This study was conducted to investigate the growth of grafted cucumber seedlings in biodegradable paper pot trays influenced by seedling age, nutrient management before transplanting, and night temperature after transplanting. Grafted cucumber seedlings in paper pot trays were supplied with different nutrient solution concentrations of 0.5 x full strength (S) (EC $0.8dS{\cdot}m^{-1}$), 1.0S(EC $1.6dS{\cdot}m^{-1}$), 2.0S(EC $3.2dS{\cdot}m^{-1}$) two times a week until transplanting. 26, 33, 40, and 47 day-old cucumber grafted seedlings were transplanted and grown at three levels of night temperature (10, 15, and $25^{\circ}C$) during ten days. Increasing nutrient solution concentration enhanced the shoot length, number of leaves, leaf area, dry weight, and relative growth rate of seedlings. With increasing seedling age, the differences in growth were greater among nutrient treatments. The dry matter percentage increased with the seedling age, but was lower with higher nutrient concentration. The specific leaf area showed the opposite results. In cucumbers transplanted at 26- or 33-day seedling ages, night temperature did not affect the growth at ten days after transplanting. However, the growth of 40 or 47 day-old seedling decreased at $10^{\circ}C$. Compared with $25^{\circ}C$, the dry weight of cucumbers transplanted at 40- or 47-day seedling ages was depressed by 58% or 71%, respectively, at $10^{\circ}C$. Accordingly, it was concluded that the optimum nutrient solution concentrations and seedling age for the production of grafted cucumber seedlings in biodegradable paper pot trays can be 1.0S and about 30 days, respectively, and night temperature should be maintained at the range of $15-25^{\circ}C$ for promoting the growth after transplanting.
