Relationship of Growth Characteristics and Leaf Surface Lipid of Tobacco

잎담배의 엽면수지량과 생육형질과의 관계

This experiment was conducted to investigate effects of fertilizers on leaf surface lipid(LSL) , and relationship between growth characteristics and LSL of aromatic tobacco, cv. Sohyang, grown in pots with 3 rates of N, P and K. With increasing the amount of applied nitrogen from 3 to 6kg110a, the contents of LSL per plant and per leaf area were decreased For maximum LSL Per plant and per leaf area nitrogen of 3kg/10a was required ,There were lit tie affected by P and K. Leaf weight per plant and mean leaf area were correlated significantly and positively with LSL per plant, but thickness of largest leaf negatively. Specific leaf weight and leaf dry weight /leaf fresh weight ratio were correlated significantly and positively with LSL per leaf area, but mean leaf area negatively.

향끽미종잎담배인 소향의 시비량을 달리하여 엽면수지량과 생육형질과의 관계를 조사한 바, 주당 및 단위 엽면적당의 엽면수지량은 질소수준간에 유의차를 보여 3k9/ 10a수준에서 많았고 인산 및 가리의 영향은 유의성이 인정되지 않았다. 주당엽면적수지량은 초장. 최대영장과 폭. 주당건엽중 및 생명중과 평균엽면적 과는 각각 정 (+). 엽후와는 부(-)의 상관이 나타났다. 단위엽면적당 엽면수지량은 단위엽면적중 및 건물율과는 정 (+), 평균엽면적과는 동일 질소수준에서 부(-)의 상관이 나타났다.
