STUDIES OF BULB HARVEST DATE AND VERNALIZATION ON GROWTH AND FLOWERING OF LILYG Chapter 1. Effect of lily bulb harvest date on the growth and flowering. Abstract: Oriental hybrid lily ‘LeReve’, ‘Sorbonne’, ‘Siberia’, and OT hybrid lily ‘Yelloween’ were used to determine the relationship between bulb harvest dates and the number of days from planting to shoot emergence and to anthesis. Data on shoot emergence and on anthesis was subjected to regression analysis of the bulb harvest dates. The number of days from planting to shoot emergence (ŶSE) and to anthesis (ŶAN) were significantly decreased, showing the linear effect responding to number of harvest dates in a year (x) for all cultivars (P≤0.001). The regression model equations of the number of days from planting to shoot emergence are ŶSE =145.7 - 0.44x (0< ŶSE <66, 180< x <331) for ‘Le Reve’, ŶSE =194.97 - 0.58x (0< ŶSE <90, 180< x <336) for ‘Sorbonne’, ŶSE =116.8 - 0.24x (29< ŶSE <74, 180< x <365) for ‘Siberia’, and ŶSE =152.8 - 0.36 x (21< ŶSE <88, 180< x <365) for ‘Yelloween’. The regression model equations of the number of days from planting to anthesis are ŶAN =229.5 - 0.45 x (66< ŶAN <149, 180< x <331) for ‘Le Reve’, ŶAN =334.5 - 0.65 x (107< ŶAN <227, 180< x <365) for ‘Sorbonne’, ŶAN =336.1 - 0.61x (113< ŶAN <226, 180< x <365) for ‘Siberia’, and ŶAN =322.1 - 0.64 x (88< ŶAN <207, 180< x <365) or ‘Yelloween’. The number of days from harvest to anthesis were significantly decreased, responding linearly to harvest dates of bulbs for all cultivars (P≤0.001). Chapter 2. Effect of duration of lily bulb vernalization on the growth and flowering. Abstract: To determine the relationship between the duration of bulb vernalization and the number of days from planting to shoot emergence and the days from planting to anthesis, Oriental hybrid lily ‘Le Reve’, ‘Sorbonne’, ‘Siberia’, and OT hybrid lily ‘Yelloween’ were used. The results showed that the duration of bulb vernalization was subjected to linear regression with the number of days from planting to shoot emergence and to anthesis. The number of days from planting to shoot emergence (ŶSE) and to anthesis (ŶAN) were significantly decreased by durations of bulb vernalization (x) for all cultivars (P≤0.001). The regression model equations of the number of days from planting to shoot emergence are ŶSE =57.8 - 0.54x (0< ŶSE <58, 0< x <107) for ‘Le Reve’, ŶSE =97.83 - 1.03x (0< ŶSE <98, 0< x <95) for ‘Sorbonne’, ŶSE =94.28 - 0.72x (0< ŶSE <95, 0< x <130) for ‘Siberia’, and ŶSE =124.73 - 1.1 x (0< ŶSE <125, 0< x <114) for ‘Yelloween’. The regression model equations of the number of days from planting to anthesis are ŶAN =140.5 - 0.54 x (43< ŶAN <140, 0< x <180) for ‘Le Reve’, ŶAN =234.33 - 1.2 x (20< ŶAN <234, 0< x <180) for ‘Sorbonne’, ŶAN=237.81 - 1.12 x (37< ŶAN <237, 0< x <180) for ‘Siberia’, and ŶAN =198.12 - 0.94 x (29< ŶAN <199, 0< x <180) for ‘Yelloween’. The number of days of ‘Le Reve’ and ‘Yelloween’ from harvest to anthesis were significantly increased by extended bulb vernalization treatment, however, those of ‘Siberia’ and ‘Sorbonne’ significantly decreased (P≤0.001). Chapter 3. Effect of lily bulb harvest date and vernalization duration on the growth and flowering. Abstract: To develop vernalization model in Lilium hybrids, Oriental hybrid lily ‘Le Reve’, ‘Sorbonne’, ‘Siberia’, and OT hybrid lily ‘Yelloween’ were used to determine the relationship between harvest dates and bulb vernalization duration with the days from harvest to anthesis, respectively. The results showed that both of the harvest date (x1) and durations of bulb vernalization (x2) significantly affected the days from harvest to anthesis by curved surface relations for all cultivars (P≤0.001). The regression equations of the days from harvest to anthesis (ŶAN) are ŶAN =234.3 + 0.68x1 + 0.41x2 (R2=0.88) for ‘Le Reve’, ŶAN =451.8 + 0.25 x1 - 0.23 x2 + 0.009 x1 × x2 (R2=0.51) for ‘Sorbonne’, ŶAN =425.5 + 0.3 x1 + 0.07 x2 – 0.002 x12 + 0.006 x1 × x2 + 0.007 x22 (R2=0.78) for ‘Siberia’, and ŶAN =390.4 + 0.31 x1 + 0.19 x2 - 0.006 x12 + 0.007 x1 × x2 (R2=0.76) for ‘Yelloween’ (for all cultivars, 180< x1 <360, 0< x2 <180, P≤0.001). Chapter 4. Changes in soluble carbohydrates, plant growth regulators in different bulb tissues, and growth and development influenced by bulb harvest date and duration of bulb vernalization of the vernalized Oriental lily ‘Siberia’. Abstract: The soluble sugar, growth regulators content were affected by harvest date and lily bulb tissues. Plant height, the number of flower buds, and abscission leave of the Oriental lily ‘Siberia’ influenced by harvest dates and duration of bulb vernalization treatment durations were investigated. The results showed that the plant height and flower buds number were not significantly affected by harvest dates and bulb vernalization, but the number of losing leaves was significantly affected by harvest dates (P≤0.05). Concentrations of soluble sucrose, glucose, and fructose were significantly different in lily bulb tissues (mother scales, daughter scales and shoot) (P≤0.05). The glucose content was significantly increased when bulbs were harvested late, but no significant differences were observed in sucrose and fructose contents regardless of bulb harvest dates. The sucrose content in shoot was significantly higher than those of in mother scales and daughter scales (P≤0.05). The IAA and GA concentrations were significantly increased as bulb harvest dates were delayed, however, ABA content was decreased (P≤0.05).

Dipping treatment of cut end of flower stems in hot water has been proven to be effective to increase the post-harvest life of various floral crops. The effects of hot water dipping treatment on the "Aktiva" oriental lily were studied. Dipping treatment of the cut flowers in water at 48 oC for 20 minutes followed by storage at 5 oC for 7 days or at 85 oC for 20 seconds and storage at 5 oC for 12 days increased the vase life by about 6 days as compared to the control. Hot water dip and low temperature storage treatments did not negatively affect the quality of cut flowers, but significantly extended longevity of cut "Aktiva" Oriental lily flowers. Wrapping material performs a pivotal role in protecting flowers against quality reduction, physical damage, water loss, and external conditions that are detrimental to storage and transported flowers. In this study, the oriental cut lily "Siberia" was sleeve-wrapped using different materials (PE sleeve, Newspaper and white-paper) and stored in a storage room at 5 oC or at room temperature, in order to assess the effects of wrapping material and storage temperatures in the postharvest period. Our findings demonstrated that 1) the vase life of Newspaper + 5 oC storage treatment and white-paper +5 oC storage groups were 3.3 days and 2.3 days longer than those in the control + 5 oC storage group, respectively; Newspaper+ AT storage and white-paper + AT storage increased vase life by 3.1 days and 2.2 days, respectively, relative to the control group; and the PE sleeve-wrapping was similar to that of the controls; 2) The flower bud opening degree at the same day, and the Newspaper and white-paper + 5 oC storage were lower than the control and PE sleeve wrapped samples; 3) the Newspaper and white-paper + 5 oC storage conditions inhibited flower senescence and contained high fresh weights, and reduced cooling damage during low-temperature storage.

The rapid development of SNS (Social Networking Service) platforms has caused an uproar around the world. The emergence of SNS platforms has also broken through the limitations of the number and geographical space of "small circles of people", "small groups" and "small organizations" in traditional society, making people in different industries, with different hobbies and occupations be connected. Meanwhile, it also eliminates the "nothingness" in the virtual network world, transplants the real human relationship to cyberspace and solves the "reputation" crisis in the development of e-commerce to a certain extent. With thousands of product reviews popping up every day on third-party SNS platforms, which ones are more authentic and reliable for enterprises? Which ones are cheap and fine? What better meets the psychological and emotional needs of consumers? It’s pretty confusing for users to get rid of the fake, retain the genuine and search for information. As far as enterprises are concerned, although most of them have recognized the important value of SNS marketing, the key point is to how to better grasp the laws of SNS marketing, do a good job in the management and operation of SNS marketing, and let the enterprises go to the world. Based on the retrieval and combing of relevant literature, this research, through prior investigation, constructs a theoretical model of the influence of Third-party Online Review Characteristics (Reviewer Characteristics, Interpersonal Relationship Characteristics and Information Content Characteristics) including Consumer Emotional media mechanism on Customer Satisfaction and Online WOM Re-diffusion Intention. Through this model, the relationship between Third-party Online Review Characteristics and Consumer Emotion, Consumer Emotion and Customer Satisfaction, Consumer Emotion and Online WOM Re-diffusion Intention, Customer Satisfaction and Online WOM Re-diffusion Intention, the mediating effect of Consumer Emotion on Third-party Online Review Characteristics and Customer Satisfaction, the mediating effect of Consumer Emotion on the Characteristics of Third-party Online Reviews and Online WOM Re-diffusion Intention are systematically analyzed. After setting the research hypotheses, a questionnaire was conducted on 850 users who were regularly active on SNS platforms in 16 cities in Shandong Province, China. And A total of 716 valid samples were returned. Based on a large number of samples, SPSS25.0 was used for frequency analysis, Reliability and validity analysis, exploratory factor analysis, confirmatory factor analysis, correlation analysis and regression analysis, which verified the research hypothesis. The positive analysis in this research shows that Reviewer Characteristics have a positive effect on Consumer Emotion, except the positive effect of Professionality on Pleasure; Interpersonal Relationship Characteristics have a positive effect on Consumer Emotion; Information Content Characteristics have a positive effect on Consumer Emotion; Consumer Emotion has a positive effect on Customer Satisfaction; Consumer Emotion has a positive effect on Online WOM Re-diffusion Intention; Customer Satisfaction has a positive effect on Online WOM Re-diffusion Intention. At the same time, through positive data analysis, the hypothesis that Consumer Emotion (Pleasure and Arousal) have a mediating effect between Reviewer Characteristics (Professionality and Authority) and Customer Satisfaction is verified and supported, except the mediating effect of Pleasure between Professionality and Customer Satisfaction. This thesis verifies and supports the hypothesis that Consumer Emotion (Pleasure and Arousal) have a mediating effect between Interpersonal Relationship Characteristics (Bond Strength and Homogeneity) and Customer Satisfaction; the hypothesis that Consumer Emotion (Pleasure and Arousal) have a mediating effect between the Information Content Characteristics (Usefulness, Reliability, Timeliness, Interactivity) and Customer Satisfaction. This thesis verifies and supports the hypothesis that Consumer Emotion (Pleasure and Arousal) have a mediating effect between the Reviewer Characteristics (Professionality and Authority) and Online WOM Re-diffusion Intention, except the mediating effect of Pleasure between Professionality and Online WOM Re-diffusion Intention. This thesis verifies and supports the hypothesis that Consumer Emotions (Pleasure and Arousal) have a mediating effect between Interpersonal Relationship Characteristics (Bond Strength and Homogeneity) and Online WOM Re-diffusion Intention; the hypothesis that Consumer Emotion (Pleasure and Arousal) have a mediating effect between Information Content Characteristics (Usefulness, Reliability, Timeliness, Interactivity) and Online WOM Re-diffusion Intention. The theoretical and practical enlightenments are confirmed in this research from the perspectives of Third-party Online Review Characteristics, Consumer Emotion, Customer Satisfaction, and Online WOM Re-diffusion Intention. Firstly, it is recommended that enterprises carefully study the Characteristics of Third-party Online Reviews and do well in guiding information reviews. The second is to continuously improve the value of Consumer Emotion and attach importance to the play of mediating effect. To focus on the role of Customer Satisfaction is the third. Finally, the improvement of the Online WOM Re-diffusion Intention must be took into account. SNS 플랫폼의 급속한 발전은 전 세계적으로 소란을 일으켰다. SNS 플랫폼의 등장은 또한 전통적인 사회에서의 "소규모 인맥", "소규모 그룹" 및 "소규모 조직"의 숫자 및 지리적 한계를 극복하였으며, 다른 산업, 취미 및 직업을 가진 사람들을 연결시켰다. 동시에 가상 네트워크 세계의 "무질서"를 제거하고 실제 인간관계를 사이버 공간으로 이식하며 전자 상거래의 "평판" 위기를 어느 정도 해소하였다. 제3자 SNS 플랫폼에서 매일 수천 개의 제품 리뷰가 등장하는 가운데 기업에게 더욱 진정한 신뢰성과 신뢰성 있는 리뷰는 어떤 것인가? 어떤 리뷰가 저렴하면서도 훌륭한 것인가? 어떤 리뷰가 소비자의 심리적, 감정적 요구를 더 잘 충족시키는가? 가짜를 걸러내고 진짜를 유지하며 정보를 찾는 것은 사용자에게는 꽤 혼란스럽다. 기업들에게는 대부분 SNS 마케팅의 중요한 가치를 인식하였지만, SNS 마케팅의 법칙을 어떻게 더 잘 이해하고, SNS 마케팅의 관리와 운영을 잘 수행하여 기업들이 세계로 나아갈 수 있는지가 관건이다. 관련 문헌 검색과 조사를 기반으로, 이 연구는 사전 조사를 통해 SNS 구전 특성과 소비자 감정 매체 기제가 정보만족도 및 2차 구전의도에 미치는 영향에 대한 이론적 모델을 구축한다. 이 모델을 통해 SNS 구전 특성과 소비자 감정, 소비자 감정과 정보만족도, 소비자 감정과 2차 구전 의도, 정보만족도와 2차 구전 의도 사이의 관계, 소비자 감정이 SNS 구전 특성과 정보만족도 간의 매개 효과, 소비자 감정이 SNS 구전 특성과 2차 구전 의도 특성 간의 매개 효과를 체계적으로 분석한다. 연구 가설을 설정한 후, 중국 산동성 16개 도시에서 SNS 플랫폼에서 정기적으로 활동하는 850명의 사용자를 대상으로 설문 조사를 실시하였고, 총 716개의 유효한 샘플이 반환되었다. 다수의 샘플을 기반으로 SPSS 25.0을 사용하여 빈도 분석, 신뢰성 및 타당성 분석, 탐색적 요인 분석, 확인적 요인 분석, 상관 분석 및 회귀 분석을 실시하여 연구 가설을 검증하였다. 이 연구의 긍정적 분석 결과는 다음과 같다. 발신자 특성은 소비자 감정에 긍정적인 영향을 미치는데, 전문성는 쾌락 감정에 대한 긍정적인 영향을 제외하고; 사회관계 특성은 소비자 감정에 긍정적인 영향을 미치며; SNS 정보 품질은 소비자 감정에 긍정적인 영향을 미친다; 소비자 감정은 정보만족도에 긍정적인 영향을 미치며; 소비자 감정은 2차 구전 의도에 긍정적인 영향을 미친다; 정보만족도는 2차 구전 의도에 긍정적인 영향을 미친다. 동시에 긍정적인 데이터 분석을 통해, 발신자 특성 과 정보만족도 사이에 소비자 감정이 매개 효과를 가진다는 가설은 쾌락 감정 과 전문성 간의 매개 효과를 제외하고 확인 및 지지된다. 이 논문은 사회관계 특성 과 정보만족도 사이에 소비자 감정 이 매개 효과를 가진다는 가설을 확인하고 지지한다. 또한 SNS 정보 품질 과 정보만족도 사이에 소비자 감정 이 매개 효과를 가진다는 가설을 확인하고 지지한다. 이 논문은 발신자 특성 과 2차 구전 의도 사이에 소비자 감정 이 매개 효과를 가진다는 가설을 확인하고 지지한다. 단, 쾌락 감정과 전문성 간의 매개 효과는 제외된다. 또한 사회관계 특성 과 2차 구전 의도 사이에 소비자 감정 이 매개 효과를 가진다는 가설을 확인하고 지지한다. 또한 SNS 정보 품질 과 2차 구전 의도 사이에 소비자 감정 이 매개 효과를 가진다는 가설을 확인하고 지지한다. 이 연구에서는 SNS 구전 특성, 소비자 감정, 정보만족도 및 2차 구전 의도의 관점에서 이론적 및 실용적인 깨달음을 확인하였다. 첫째로, 기업은 SNS 구전 특성을 신중히 연구하고 정보 리뷰를 지도하는 데에 노력해야 한다. 둘째로, 소비자 감정의 가치를 지속적으로 향상시키고 매개 효과의 역할을 중요시해야 한다. 세 번째로, 정보만족도의 역할에 초점을 맞추어야 한다. 마지막으로, 2차 구전 의도의 개선을 고려해야 한다.
