  • The purpose of this study was to find new way for vitality of flower shop. The subjects for this research were composed of 58 male and 155 female. In survey of satisfaction of flower shop's product price, 'satisfied' responses in male and female respondents were 8.62 and 14.21%, respectively. Results of survey of consumer's awareness on packaging of flower shop's products have shown that the 'satisfied' responses in male and female respondents were 6.88 and 12.91%, respectively. In question of the satisfaction of flower products as a gift, the 'satisfied' responses in male and female respondents were 8.61% and 1.95%, respectively. In question of the attitude of seller, the 'satisfied' responses in male and female respondents were 6.88% and 6.46%, respectively. In survey of the mind of consumer's repurchase, male and female respondents were satisfied 5.16% and 9.05%, respectively. Our results have shown that consumer's satisfaction in most questions was of low level. Therefore, we propose that these results are associated with the needs of active efforts of flower shop's manager.

  • Photoperiod is one of the factors affecting productivity of cucumber plant by inducing ethylene hormone production and so triggering flower sex differentiation into female flower. However, only few studies have been perfomed in order to reveal the effect of photoperiod in molecular level in relation to the flower differentiation. Therefore, in this study, Mercy cultivar of cucumber (andromonoecious) was treated with photoperiod of 8, 12, 16 hours of light, while control received no treatment of additional light. Photoperiod of 8 hours was achieved by blocking the sunlight with shade net and 16 hours by giving longer light exposure using white LEDs. Cucumber's flowers were quantified and the apical and lateral shoots were extracted to evaluate the gene profile related to the photoperiod, ethylene production, and female flower differentiation, which were CsACS2, CsETR1, CsCaN, and CsPIF4 using PCR method. Photoperiod of 8 hours affected the production of female flower with average number of 6.7 flowers in main stem and 8.0 flowers in lateral stem, compared to photoperiod of 12 and 16 hours which produced 3.7 and 2.0 flowers in main stem with 7.0 and 11.3 in lateral stem, respectively. In silico studies in this experiment resulted in proposed model of signal transduction that showed the connection between ethylene production and flower differentiation. PCR analysis confirmed the expression of CsACS2, CsETR1, and CsCaN, that was positively correlated with numbers of female flowers in cucumber, but the expression of CsPIF4 that represent photoperiod haven't been confirmed correlated with the ethylene production and flower differentiation.

  • This study was conducted to test the significant difference of fertility variation among families and to select superior families for acorn production in the breeding seedling seed orchards (BSSOs) of Quercus acuta and Quercus glauca. The seed orchards were located in Jeju island and established by seedlings raised from selected parents for genetic testing in 2006. In the spring of 2021, the numbers of female and male flower were counted from 5 to 10 individuals per family in the BSSOs. To test statistical significance of which parameter is not satisfied through the normality test, we used a nonparametric analysis. Correlation analysis was performed to quantify the association between female and male flower production. As the results, the significant difference of flower production among families was found in both seed orchards. The averages of female flower production were 65.3 and 181.9 in Q. acuta and Q. glauca. The positive Spearman's rank correlation was existed between male and female flower production. Broad-sense heritability on female and male flower production were 0.191 and 0.147 in Q. acuta, and 0.285 and 0.068 in Q. glauca, respectively. Sexual asymmetry (e.g., maleness index) between female and male, and contribution variation among families (e.g., parental balance) were analyzed to find reasonable alternatives in the management of seed orchards. Effective population size of seed crops was predicted as a concept of status number. Loss of gene diversity (accumulation of group coancestry) would not be alarming in the BSSOs. Our results would be helpful to select breeding materials for establishing new seed orchards and to supply genetically improved seeds of evergreen oaks, which is one of the backbones of the strategy of carbon sink in the 2050 Carbon Neutrality of Korea Forest Service.

  • This study was conducted to identify cross compatibility with table grape and pollen characteristics by flower type in Vitis amurensis Rupr. (GW-22, GW-45, GW-56, GW-200, GW-202 and GW-300) collected in Gangwon area. Flower structure, germinability and morphology of pollen, and cross compatibility with table grape were examined. Flowers of GW-22 and GW-56 had an aborted gynoecium and five erect fdaments, and all of them was male. The percentage of pollen germination of GW-22 and GW-56 on the agar medium was 27.6-29.8%. Flowers of GW-45, GW-200, GW-202 and GW-300 had well-developed pistils and five stamens with curled filaments. The percentage of pollen germination of female plant on the agar medium was 0%. Pollen grail)s from GW-22 and GW-56 (male flower) have symmetrically distributed three furrows on their surface and each furrow contains a germ pore at the equatorial level (Tricolporated). GW-45, GW-200, GW202, and GW-300 (Female flower) produced pollen grains with no germinative structures (acolporated). In self-pollina-tion of female flowers, berries of clusters were no berry and no seed. Therefore, flower structure in V. amurensis proved to be that of other dioecious Vitis species. In cross combination of female and male flower of V. amurensis made normal seeds. In cross combination of table grape and V. amurensis of male flower made normal seeds. But, in cross combination of female flower of V. amurensis did not make seeds. Therefore, V. amurensis was cross compatible with vitis spp, and V. amurensis varieties may contribute to breeding studies of Vitis spp.

  • Morphological changes of flowers and insect visitors were observed to investigate pollinator of Caesalpinia decapetala. The flowers of C. decapetala are protandrous. Functionally, the flower is changed from male to female. As a male, pollen grain is released after anther dehisced while style is immature. After completed pollen grain release, the style starts to lengthen. It helps the stigma to easily touch the carpenter bee's thorax covered with pollen grain. At this time, flower functions as a female. The majority of taxa and individuals observed were Hymenoptera. The most frequent visitor was the Xylocopa appendiculata circumvolans, carpenter bee. Carpenter bees exhibited only typical pollinator behavior among flower visitors, with touching reproductive organs and seeking nectar at the same time. The pollination behavior is as follows. Soon after carpenter bees perceived guide mark, they foraged rightward and grasped style and stamens with legs and they inserted proboscis into standard petal to seek nectar. With this behavior, the pollen grains of the male flower transfer to the ventral thorax of the carpenter bee. As the carpenter bee moves to another female flower, the deposited pollen grains are delivered to the stigma.

  • The purpose of study was to analyze secreted nectar volume, nectar sugar content and amino acid in addition to estimating honey quantities that can ultimately reap in male and female flowers of Evodia daniellii Hemsl.. The maximum blooming period of male flowers was on 24 to 26 July in 2012. On average, nectar volume secreted by nectary was $2.73{\pm}0.73{\mu}L$ from one male flower and nectar concentration showed 17.4%. The maximum blooming period of female flowers was on 7 to 9 August in 2012. Nectar volume secreted by nectary was $0.63{\pm}0.49{\mu}L$ from one female flower and nectar concentration showed 25.7%, averagely. As results of correlation analysis between the meteorological factors and nectar characteristics, we found that nectar quantities and concentration were influenced by temperature and relative humidity. Sugar content was calculated at $48.0{\pm}5.2{\mu}g$ per a male flower and $37.8{\pm}8.7{\mu}g$ per a female flower, which meant that both values were not significantly different (Mann-Whitney's U-test, p=0.400). The minimum estimates of honey harvest for a male and female inflorescence were 67.8 g and 53.5 g, respectively. Analysis of amino acid showed that Serine, Glycine and Alanine were more abundant in male flowers, however Asparatate, Glutamate, Asparagine and Glutamine were more abundant in female flowers.

  • The purpose of this study was to determine whether Rescue Remedy, the most popular Bach flower, was effective in reducing stress and fear in pets, thereby alleviating behavioral problems such as aggression and improving the welfare of canines. The evaluation was conducted with canines without diseases or behavioral problems. Two male Spitz dogs (average age 15 years, average weight 8 kg), one female Spitz dog (age 12 years, weight 8 kg), and nine Shetland sheep dogs (average age, 11 years, average weight 9 kg) were used in the study. Responses in the heart rate were found in three groups of dogs during nail trimming (P < 0.05). Heart rate variability in each of the three canines that were 8 and 13 years old were similar on the Bach flower remedy (P > 0.05). Ethogram observations during nail cutting indicated a reduction in aberrant behavior after administration of Bach Flower remedy. In conclusion, the application of Bach flower Rescue Remedies resulted in substantially lower heart rates and a reduction in stress-related behaviors was observed.

  • Some Korean terminologies on reproductive structures of seed plants in plant morphology, written incorrectly in many books, were analysed to propose accurately expressed terminologies. 31 books in areas such as general biology, plant biology, plant morphology, and biological dictionaries and glossaries were selected to analyse the accuracy of the terminologies for reproductive structures in gymnosperms, e.g., cone or strobilus, seed (or ovulate) cone and pollen cone, and conifer(s) or coniferous plants, and for flower structures in angiosperms, e.g., corolla, anther, filament, pistillate (or female) flower and staminate (or male) flower, apocarpous, and syncarpous. The definition and etymology of the terminologies were traced in 4 textbooks of plant anatomy and 2 dictionaries of biology and botany written in English. On the basis of the definition, etymology, and principles for terminology formation according to the International Organization for Standardization (ISO 704:2000), reasonably expressed Korean terminologies were proposed. All of the 8 terminologies examined in this study were included in the glossary of biological terminologies, published by the Korean Association of Biological Sciences in 2005, and designated as an editorial source for science and biology textbooks for middle and high schools by Ministry of Education in 2007. However, the only 1 of the 8 terminologies described in the glossary were consistent with the proposed expression in the present study. These inconsistencies indicated the need for a reassessment of this glossary of biological terminologies. The newly proposed terminologies would facilitate mutual understanding between teachers and students of plant biology.
