The purpose of seed coating is to make seedling mechanization possible by enlarging the seed size. The objective of this study was to determine the optimum of polymer and particulate matters for seed coating in perilla. There were significant differences of percent germination and germination speed in accordance with the coating polymer and the concentration. Among the coating polymer, germination of seeds using polyvinyl alcohol (PVA) was generally smooth, and followed by polyvinyl pyrrolidone (PVP), hydroxyethyl cellulose (HEC), and methyl cellulose (MC). The germination rate was also different according to the coating particulate matters. Generally, percentage germination and germination speed of seeds using the mixture of diatomaceous earth, talc and bentonite were higher and faster than using other coating materials, respectively. However, percentage germination using limestone was low, and percent germination of coated seeds with coating material showed the tendency of decreasing more than that of the seeds just added with coating particulate matters.

The effect of plant growth regulators on perilla(Perilla ocymoides L.) germination was evaluated in the laboratory at 15℃, 20℃ and 25℃. Seeds of perilla cultivars 'Ipdulgge', 'Miryang', 'Yeupsil', 'Jukjaso' and 'Chungjaso' were dark-treated in varied level solution of gibberellic acid(GA3), 6-benzylaminopurine(BAP) and combined GA3 with BAP for a 1 day at 20℃. The effect of plant growth regulators varied among cultivar. Plant growth regulators treated did not affect percentage germination of all perilla seeds, but showed shorter number of days to 50% of the final germination(T50) and mean number of days to germination(MDG) than those untreated seeds. The germination behavior of all cultivar was highly correlated with plant growth regulators kinds and their concentrations. GA3 had to improve germination in 'Miryang', 'Yeupsil', 'Jukjaso' and 'Chungjaso', but the effect varied with applying level. GA3 250μ M treatment showed higher percent germination and shorter T50 and MDG of 'Ipdulgge' perilla than those of untreated, when the seeds were germinated at 15℃ , 20℃ and 25℃. When plant growth regulator treatment in 250μ M GA3 + 250μ M BAP of 'Miryang', in 250μ M GA3 of 'Yeupsil' and 'Chungjaso', and 100μ M GA3 + 100μ M BAP of 'Jukjaso' perilla seeds exhibited a faster rate of germination then those untreated seeds.

The purpose of this research was to search for optimized priming conditions for improving perilla(Perilla ocymoides L.) seed performance, and effect of seed priming on germination under adverse environmental conditions such osmotic, salt, and ABA stress. Among the nine different chemicals, at two concentrations each, Ca(NO3)2 at 200 mM resulted in the shortest days to 50% of the final germination percentage (T50). Seeds primed at 20℃ for 3 days germinated most rapidly at 25℃ temperature tested. Air-drying for 3h at 30℃ and room temperature after priming maintained all the advantages achieved during priming treatment. However dried at 50℃ significantly reduced germination and beneficial effect were lost gained by priming. Priming has improved the rate and uniformity of seed germination in perilla, especially under adverse environmental such osmotic, salt, and ABA stress. Germinability was decreased under the increased stress from osmotic, salt, and ABA. Under these increased stress, the germinability of primed seeds was higher and earlier than those of nonprimed seeds.

Preplant seed hydration treatments, particularly at low water potential, mobilized seed's resources that are utilized for rapid and synchronous germination, improved emergence rare, and larger stand size and yields. Seed priming is ideally suited to combat or lessen the impact of a number of soil and climatic constraints, including cold and wet conditions, thermoinhibition, drought, and incidence of diseases. The priming treatment is versatile enough to be integrated with other preplant physiological and non-physiological treatment to combat other internal and external constraints. These include chilling to break the primary dormancy, permeation with hormones to prevent the induction of secondary dormancy, and treatment with pesticides and beneficial microbes to combat seed and seedling diseases during stand establishment. The success or failure of priming treatment are influenced by a complex interaction of factors including plant species, osmeticum, water potential of the priming agent, during of priming, temperature, seed vigor, and dehydration and storage conditions following priming. Seed priming treatment under controlled temperature conditions, allows seeds to imbibe water and go through the initial stages of germination without radicle protrusion through seed coat. The use of a matricum for solid matrix priming(SMP) follows the same principals as for solution osmotic priming. The choice in mainly based on choosing a material wherein water uptake by the seed can be more closely regulated. Concentration of the matricum or osmoticum can be altered to fine-tune water relations The other factors that effect the results from seed priming, aeration, temperature, duration, light. dehydration, and storage are dependent on the species being primed. All crop seeds need air to germinate, thus optimizing aeration during priming. Germination rate and uniformity can be improved by priming for a vast array of crops as evidenced. The numbers of different species commercially primed and available to producers is quite small. The reasons for this might include the high charges to the grower of primed seed, lack of knowledge and or experience by growers of the results obtained from priming. Finally, more practical and essential subjects such as seed vigor and priming effectiveness, effects of dehydration after priming, storage conditions, and the ideal combination of matrix-solid, water, and seeds in SMP treatments are in need of further studies.

It's not uncommon for the amount of leaves to be reduced significantly due to the early differentiation of flower-bud by short-day condition when growing perilla for harvesting the leaves in the greenhouse during the winter. This study analyzed the effect of day-length on the growth and regulation of flowering, which are closely related with differentiation of flower and amount of leaves. Development of new leaf was inhibited by short-day treatment for more than 5 days. As the period of short-day was longer, the effect on the development of new leaf inhibition was more evident. Number of leaves was reduced in both 40 days and 110 days short-day treatments as period of short-day length was longer. Short-day treatment for less than 3 days did not induce flowering, but short-day treatment for more than 5 days induced flowering. As the period of short-day treatment was shorter, percentage of flowering was lower and days to flowering was longer. That is, when treated for 20 days, flowering began in 20 days. Seed weight was reduced as the length of short-day treatment was longer.

The lower leaves shading in upper leaves is unknown to be reduced significantly due to the early differentiation of flower-bud by dark treatment of leaves when growing perilla for harvesting the leaves in the greenhouse during the winter. This study analyzed the effect of dark treatment of leaves on the growth and regulation of flowering, which are closely related with differentiation of flower and amount of leaves. One leaf and 3 leaves per plant were dark treated for 0, 5, 10 days. Plant hight was reduced in 3 leaves treatment, but there was no difference in 1 leaf treatment. Stem diameter was reduced in both 1 leaf and 3 leaves treatments, which was more significant in 3 leaves treatment. Leaf area was reduced when 1 leaf was treated for 10 days, but there was no difference when 1 leaf was treated for 5 days. When 3 leaves were treated, leaf area was no difference between treatments. However, leaf area which 3 leaves were treated was reduced more significantly than that 1 leaf was treated. Seed weight was remarkably decreased when 1 leaf was treated for 10 days, and it was decreased when 3 leaves were treated for more than 5 days.

본 연구는 오이종자의 발아율 향상과 발아촉진을 위해 처리가 간편하고, 처리비용을 절감할 수 있는 hydropriming의 실용화를 위해 필수적인 요인에 관한 실험을 수행하였다. 오이 종자의 발아촉진에 최적 priming 처리제는 50mM ·NaN03였다 유근장 및 유근 건물 중은 priming 처리제 종류에 따라 유의적인 차이는 없었으나, priming 및 hydropriming 종 자는 무처리보다는 높았다. 그러나 50mM NaN03와 hydropriming 처리간 발아력 증진 효과가 동일하여 오이종자에서 물을 이용한 hydropriming은 처리비용을 절감할 수 있어 합리적인 종자처리였다 오이 종자의 hydropriming 적정 처리온도는 20℃, 처리시간은 24시간이였다. Hydropriming시 적정 용액량은 종자 2g에 대한 용액량 10m 공급처리가 발아율 향상. T50,MDG 단축 및 유근생장에 효과적 이였다. 인위노화 종자는 발아율이 감소하였고 발아속 도는 지연되었으며, 비정상적인 발아는 증가하였다. 활력이 저하된 노화종자를 hydropriming 처리는 발아율이 향상되었고, 조기 발아하였다 또한 비정상인 발아는 감소되었으며, 유근생장이 촉진되어 종자력이 부분적으로 회복되었다. 이러한 경향은 노화일수록 경과된 종자일수록, 부적당한 발아조건인 15℃ 명확하게 나타났다. Various hydration treatments have been devised to improve the rate and uniformity of seed germination as well as seed viability. Hydropriming and priming, the imbibition of seeds in distilled water and osmotic solutions respectively, are useful techniques for early establishment of uniform seedlings. In this study, the optimum conditions were determined for hydropriming cucumber seeds. Effects of hydropriming were compared those of osmotic priming. Seeds, hydroprimed or primed with distilled water and 50 mM NaN03 at 20℃ for 24 hour, showed shorter number of days to 50% of the final germination percentage(T50) , and mean number of days to germination(MDG) than those untreated seeds. Nor did the ratio between the amount of seed to the volume of solution affect percent germination. But, hydorprimed with 10 ml distilled water showed improving the rate of germination than other treatment seeds. Hydropriming the aged seeds did improve percent germination at 15℃ and 25℃ . The T50 and MDG values were reduced significantly by hydropriming the aged seeds regardless of germination temperature. In addition to being simple and inexpensive, the quicker germination of hydropriming at low temperature. The effectiveness of hydropriming seeds caused some increase in the percentage of normal seedlings.

This study was conducted to estimate growth of leaf and shoot and flowering as affected by GA3 treatment in vitro. Plant height was longer as the concentration of GA3 was higher up to 2.0mg/l. Stem diameter was thick up to the concentration of GA3 was 0.1mg/l , but become thinner as the concentration of GA3 was higher. Root weight and root length were well developed in GA3 concentration was 0.5∼2.0mg/l. Number of roots was more in GA3 concentration was 0.5 and 1.0mg/l . The first flowering occurred in 40 days after 0.5 mg/l GA3 treatment. As the concentration of GA3 was higher, flowering was delayed. Number of flowering was significantly increased in GA3 concentration was 0.1 and 0.5mg/l. However, it was gradually decreased after 60 days. Percentage of flowering per plant was highest in GA3 concentration was 0.5mg/l , but it was lower as the concentration of GA3 was increased.
