Gibberellin을 Seed Potato에 처리함으로서 seed potato내의 환원당과 비환원당의 소장과 붕아경의 현미경적인 조직의 변화에 대한 몇가지 실험결과를 요약하면 다음과 같다. 1) Gibberellin을 처리한 Seed potato에 함유한 환원당은 처리하지 않은 Seed Potato에 비하여 현저히 증가하였으며 그 증가정도는 붕아일수의 경과에 따라 차가 심하였다. 처리농도에 있어서는 10ppm구가 5ppm구 보다 증가하였으나 파종 14일부터는 반대의 경향을 인정할 수 있었다. 2) Gibberellin을 처리한 Seed Potato에 함유한 비환원당의 소장도 환원당과 동일한 경향임을 인정할 수 있었다. 3) 붕아경은 Gibberllin 5ppm 및 10ppm 구 공히 Control에 비하여 신장이 빨랐으며 14일후에는 10ppm 구는 Gibberellin처리에 의한 도장현상으로 약간의 생육장해가 발생하였다. 4) Gibberellin 처리에 의하여 붕아된 붕아경은 종단 및 횡단세포가 현저히 커졌으며 피시부나 중심부가 균등하게 팽대하였고 10ppm구가 더 커졌음을 인정할 수 있었다.

Effects of gibberellin on alpha and beta-amylase activities of Aspergillus orygae var. microsporus have been studied. Results obtained are as follows: 1. The growth of mycelium and dry weight of surface ped was accelerated by 0, 0001% gibberellin solution, spores of Aspergillus oryzae var. microsporus. were preveously soaked for three days. 2. Adding to culture media with 0, 0015% gibberellin, alpha-amylase was increased 50% much as beta-Amylase was as much as 50%.

This experiment was conducted to determine Gibberellin content in tobacco leaves at different growth stages in relation to nitrogen levels applied. Some of the results obtained can be summarized as follows: 1. The content of Gibberellin showed an increasing tendency as the levels of nitrogen increased. 2. The highest content of Gibberellin was observed at 60 days after transplanting, showing much higher than those of 30 and 90 days after transplanting. 3. The content of Gibberellin at various growth stages under different nitrogen levels ranged from 0.2490 ng to 10.9308 ng per IKg of fresh leaf weight of Burley 21. 4.The kinds of Gibberellin present in tobacco leaf appeared to be Gibberellinl ,9,19 and 20.

춘파과맥 ${\ulcorner}$완주봄보리${\lrcorner}$의 종자를 5~100ppm의 지벨레린의 용액에서 백체출현기까지 최아하여 발아 및 포장시험을 실시한바 그 성적을 요약하면 다음과 같다. 1. 지벨레린최아에 으하여 발아율의 감퇴없이 2 (상온구)~3일(저온구)의 발아촉진을 보였다. 2. 지벨레린최아를 하면 초기생육촉진이 일면으로는 주장적현상이 현저하였는데 그경향은 고농도 일수록 심하다. 3. 지벨레린최아로 근생장의 억제작용은 전연 인정되지 않았다. 4. 포장조건에는 발아촉진의 효과가 별로없었고 고농도처리에서는 발아율의 감퇴를 초래하여 수수감소 및 수량감소를 초래하였다. 5. 고농도일수록 초기의 주장화경향이 심하고 회복도 늦으나 생육중기에 가서는 거의 모두 정상으로 회복되며, 따라서 출수 성숙 및 간장이 처리에 의한 변이를 보이지 않았다. 6. 5~10ppm의 농도에서는 발아저해가 적고 초기의 주장화경향이 적으며 수수감퇴도 적은 반면에 수장이나 천립중은 증대경향이어서 결과적으로 중수경향을 보였으나 재 검토가 필요하다. 7. 지벨레린 최아만으로는 발아촉진은 기대되나 조숙화는 기대되지 않는다.

Mung bean sprout has been grown for 96 hours by soaking mung bean in such eight test divisions as Gibberellin 5-50ppm solution, well-water, and so on. Study on the charge of vitamin C an reducing sugar during its growth can be summarized as follows. 1. During the growth of mung bean sprout, the length and weight in the sample treated with Gibberellin 20ppm are highest of all Gibberellin divisions. 2. When mung bean sprout has grown for 24 hours, its vitamin C content reaches maximum in each sample. 3. There is little dehydro asscorbic acid in each sample during the growth period of 24-96 hours. 4. During the period of growth, the content of vitamin C in the sample treated with Gibberellin 5ppm are highest of all. 5. When mung bean sprout has been grown enough for cooking, in 48 hours, the content of vitamin C in the sample treated with Gibberellin 10ppm is highest but a significant difference is not recognized. 6. After 24 hours growth, vitamin C decreases but reducing sugar increases.

This study was conducted to develop gibberellin treatment technique to enhance flower initiation in Aquilegia japonica Nakai & H. Hara. Seedlings were planted in 12cm-diameter pots on October 2016 and grown in green house. Ambient temperature in the green house was set at minimum $15^{\circ}C$ during day and night to suppress flower initiation at cold temperature condition. Two different types of gibberellin, $GA_3$ and $GA_{4+7}$, at 4 different concentration levels 100, 200, 400 and 600 mg/L, were tested in this study. Gibberellin was sprayed first at planting and secondly at 1-week after planting. Ten to fifteen ml of gibberellin was sprayed for each pot. Plant height and petiole length were elongated by both gibberellin types, flowering was more enhanced by $GA_3$ (91.7~100%) compared to of $GA_{4+7}$. However, abnormal flower was less observed in $GA_3$ treatment (0~16.7%) than $GA_{4+7}$. Number of flower stalks per plant ranged from 1.9 to 2.5. Number of flowers per plant ranged from 6.8 to 10.3. Differences in flowering characteristics between treatments were statistically significant. Optimal gibberellin treatment to enhance flower initiation in A. japonica Nakai & H. Hara substituting cold treatment was $GA_3$ at the concentration between 400 mg/L to 600 mg/L.

Gibberellic acid did not affect ethylene production, whereas gibberellin biosynthesis inhibitors triggered ethylene production in dormant tubers. Gibberellic acid did not induce sprouting of dormant tubers, however, treatment of gibberellin biosynthesis retardants enhanced sprouting rates. Sprouting rate in ancymidol-treated tubers was highest among gibberellin biosynthesis retardants. Sprouting rate of tubers treated with ancymidol increased to $91.4\%$. Batatasin-III content in $GA_3$ treated tuber was increased in the highest concentration $(30{\mu}g\;I^{-1})$. Tubers treated with mepiquat chloride, Batatasin-I was increased steadily, but contents of Batatasin-III and V showed dramatic decrease at the $ 1,000{\mu}g\;I^{-1})$ concentration. This infers that gibberellin biosynthesis retardants play key roles in promoting breaking dormancy on dormant tubers of Chinese yam.
