Effect of the Application of Three Primary Elements and Lime on the Seed Oil Content and Yield Components of Perilla

3요소(三要素) 및 석회처리(石灰處理)가 들깨의 지방조성(脂肪組成) 및 수량(收量) 구성요소(構成要素)에 미치는 영향(影響)

This experiment was carried out to investigate the effect of the application conditions of fertilizers on the seed yield and oil content of Perilla ocymoides L. The results were summarized as follows; 1. Plant height, number of nodes and branches, and number of clusters were not significantly affected by the application of fertilizers, but yield capacity and oil content of perilla increased by the potassium application. Phosphate application resulted in incerased seed yield and calcium application significantly affected the oil content. 2. The combined application of phosphate, potassium and calcium resulted in a big seed size but oil content was not high. 3. The fatty acid composition of perilla was not showed affected by the effect of application of fertilizer Unsaturated linolenic acid (64.5 %) was highest in the content of main fatty acid in perilla lipid followed by oleic acid (14.0 %), linoleic acid (13.8 %), palmitic acid (5.4 %) and stearic acid (1.8 %). 4. The contents of inorganic substances in seed ash of perilla showed the distribution pattern of K(21.3 %), Ca(12.8 %), Mg(8.2 %), Fe(0.34 %), Zn(0.15 %), Mn(0.10 %) and Na(0.08 %).

들깨의 시비조건(施肥條件)에 따른 수량(收量)과 함유량(含油量) 등을 조사한 결과는 다음과 같다. 1. 시비조건(施肥條件)에 따라 초장(草長), 가지수, 마디수, 화방수는 별 차이가 없었으며 가리시용(加里施用)은 들깨의 수량(收量)과 함유량(含油量)을 증가시키는 효과가 있었고,인산혼용(燐酸混用)은 들깨의 수량(收量)을, 석회(石灰)는 함유랑(含油量)을 증가시키는 효과가 있었다. 2. 가리(加里), 석회(石灰), 인산(燐酸)의 조합시비(組合施肥)는 종실(種實)을 크게 하나 함유량(含油量)은 낮았다. 3 들깨의 지방산조성(脂肪酸組成)은 lenolenic acid 가 64.5%로 최고(最高)였으며 다음이 oleic acid (14.0%), linoleic acid(13.8%) palmitic acid (5.4%). stearic acid (1.8%) 순이었고 시비조건(施肥條件)에 따른 특별한 분포경향을 보이지 않았다. 4. 들깨 종실(種實)의 회분중 무기성분(無機成分)은 K(21.3%), Ca(12.8%), Mg(8.2%), Fe(0.34%), Zn(0.15 %), Mn(0.1%), Na(0.08%) 순이었다.
