Respiration Rate in Each Organ of Ginseng Plant

인삼 식물체의 부위별 호흡량

This study was conducted to know the respiration rate in different organ of 4 years old ginseng plant on June 14 and in different root conditions of 6 years old on October 1. Respiration rate of each organ was the increasing order of young berry, leaf, peduncle, stem and root at all temperature(15$^{\circ}C$ to 30$^{\circ}C$). Temperature coefficients of respiration rate from 15$^{\circ}C$ to 30$^{\circ}C$ of each organ were 2.39 in young berry, 1.75 in leaf, 1.57 in root, 1.17 in stem and 1.16 in peduncle. There was no difference between respiration rate of large size root (117${\pm}$8.8g) and that of small size (54${\pm}$4.0g) in 6 years old ginseng. Respiration rate was decreased with the decrease in the water content in root, especially in small size root. And respiration rate of red skin root was higher than that of healthy root.

본 시험은 6월 14 일에 4년생 인삼 식물체의 각 기관별, 10월 1 일에 6년생을 근상태별로 구분하여 호흡량을 측정하였던 바 그 결과는 다음과 같다. 1. 기관별 호흡량은 유과≒엽>화경>경≒근의 순이었다. 2. 15$^{\circ}C$~3$0^{\circ}C$ 사이에서의 기관별 호흡계수는 유과 2.39, 엽 1.75, 근 1.57, 경 1.17, 화경 1.16이었다. 3. 채굴 당시 대편삼(117$\pm$8.8g)과 소편삼(54$\pm$4.0g)간에 호흡량의 차이는 인정되지 않았다. 4. 근내 수분함량이 감소할수록 호흡량은 저하되었으며 그 정도는 소편삼에서 현저하였다. 5 . 건전삼에 비해 근적변삼에서 근호흡량이 현저히 많았다.
