  • 천연화합물과 합성화합물은 모두 합쳐서 식물생장조절제라 부르고 이들 화합물은 경우에 따라 식물의 기간들의 생장율을 촉진하거나 억제한다. 호르몬이란 용어는 천연적으로 발생하는 색물생장 조절제에 국한되는 것이다. 실제의 응용에 있어서 합성된 생장조절제가 사용되는 것은 이 물질이 생체내에서 안정도가 더 크기 때문이다. 따라서, 합성물질은 식물 호르몬의 구조적인 유사성으로 흉내를 내거나 내생 호르몬들의 생합성, 전류, 및 대사를 조정해서 그 수준을 조절하게 된다. 그래서, 식물생장 조절물질들의 기능과 가능력을 이해하기 위해서 분자수준에서 식물호르몬들의 작용의 양상을 고찰한다.

  • This experiment was carried out to find of shortening degree of plant height and seed yield of sesame by different treatment of fertilizer and regulator application. Treatment of higher yield was compost, foliar spraying of Tachigaren chemicals and pinching + 1. 5 times as much as control application of 3 elements which was nitrogen, phosphate, potassium. Especially, Tachigaren chemicals plot was showed increasing lodging resistance because of shortening stem of 6cm compare with control plot and more 8% than control plot in seed yield. Expectant treatment of seed yield was application of compost 2,000Kg per l0a. Foliar spraying of Tachigaren chemicals at 6 leaves full-open of main stem was expected higher yield as well as shortening stem.

  • A series of experiments were carried out to know the effect of growth retardants on the growth of rice seedlings and ethylene evolution from the rice seedlings. The results suggested that the reduction rate in order of plant height was S-327 > BAS-106 > NTN-821 > PP-333 > CGR-811. The heigher concentration levels of growth retardants applied. the more effective reductions of plant height were found. Ethylene evolution from the rice seedlings was significantly negative correlated with plant hight of of seedlings in all treatments.

  • This experiment was conducted to evaluated the effect of CM (plant growth regulator) treatment on flowering, pod maturing and root yield components of Astragalus membramaceus Bunge. Three dilution rates (60, 70 and 80 times) were sprayed at $3{\sim}4$ leave stage. As the results, flowering was delayed $25{\sim}35$ days than August 13 of control and higher dilution rates was more effective to delay flowering. At the havesting time, be compared with non-treatment, plant height reduced $7.6{\sim}18.9\;cm$ and number of matured pods were decreased $50.6{\sim}76.1$ by increasing dilution rates. However, weight of dry root per plant was increased to 29% and dry root yield per 10a was increased to 28% in dilution rates 70 compared with non-treatment.

Effects of a Growth Retardent Paclobutrazol on the Oil, Protein Content and Fatty Acid Composition of Peanut(Archis hypogea L.) (생장조정제(生長調整劑) Paclobutrazol이 땅콩의 유분(油分) 및 단백질함량(蛋白質含量)과 지방산(脂肪酸) 조성(組成)에 미치는 영향(影響))

  • This study was conducted to evaluate the effect of retardent Paclobutrazol on the seed quality factors such as oil content, protein content and fatty acid composition in peanut cv. Saeddle(early variety) and Napung(medium variety). The results are summarized as follows : Oil content of seed was appeared to increase when Paclobutrazol was applied and especially it was remarkably increased at 120 ppm-90 DAS both in varieties. Even though protein content showed a little increase at 120 ppm-70 DAS in early variety and 120 ppm -90 DAS in medium variety, however, it was decreased in most case. Saturated fatty acids such as palmitic and stearic acid was reduced by Paclobutrazol treatment but unsaturated fatty acids such as oleic, linoleic, eicosenoic and eicosadienoic acid was tended to increase in early variety while palmitic acid was increased in medium variety but linoleic acid reduced and no change was observed in oleic acid content.
