Effect of Maturity on Physiological Change and Postharvest Quality of Cut Gerbera

利用'Furore'和'Ornella'非洲菊切花於不同成熟度採收，調查其呼吸率、乙烯釋放量、鮮重變化、吸水性、瓶插壽命及開花品質。結果顯示，採收成熟度為兩性小花雄蕊3輪以上之高成熟度切花，具有較高的呼吸率及乙烯釋收量，乙烯釋放量上升的情形亦最早發生。高成熟度切花之瓣澱粉含量較高，花朵鮮重、瓶插期間吸水量及花朵直徑較大。且莖部組織中皮層細胞較圓整，導管較大、數目也較多，但過高的採收成熟度，會增加'Ornella'品種的花莖彎曲度，及使'Furore'品種舌瓣花早藍化，因而瓶插壽命較短。蕾期採收之切花雖呼吸率及乙烯釋放量較低、乙烯上升情形發生較慢等優點，但花朵開放直徑較小、花色表現較差，觀賞品質不佳。因此，建議國內鮮銷非洲菊切花之商業採收成熟度為：舌瓣花完全展開但兩性小花尚未開放至兩小花雄蕊1~2輪成熟採收，可有花朵直徑、瓶插壽命及花色表現等觀賞品質較佳之結果。Two cultivars of Gerbera jamesonii Bolus ‘Furore' and ‘Ornella' were tested in this study to investigate the physiological change and vase life of gerbera cut flowers at different maturity stages. The highest respiration rate was found on non-anthesis monoclinous dicyclid florets after flowers harvested. The highest ethylene production was found receptacle when flowers were cut and upper part stem in 6 days vase life. Cut flowers harvested at maturity with third circle stamens of monoclinous dicyclic florets presented the highest respiration rate, the highest ethylene production, and increased the earliest ethylene production. Highly maturity cut flowers contained higher starch content on petal, gained more flower fresh weight, and larger flower diameter and water uptake than those of less mature cut flowers after flowers harvested. In stem tissues, cortex cells were round and complete. The number and size of vessels showed bigger diameter than that of younger tissues. However, over maturity cut flowers were easily bend on ‘Ornella' gerbera and showed easily bluish and decrease vase life on ‘Furore' gerbera flowers. Gerbera cut flowers harvested on bud stage had the advantage of the low respiration rate, low ethylene production, and slower ethylene increased trend, however, flower diameter presented smaller when flower bloomed, florets was fade cause poor flower quality. The good gerbera flower performance showed the requirement with ray floret fully open, disk floret were not open yet, and considered the maturity of one or two of the stamens of monoclinous dicyclic florets could result flower diameter, vase life, and flower color performed well

(51(2):111-124)Effect of Ethylene and Preservatives on the Vase Life of gerbera jamesonii Cut Flower

本試驗以商業栽培品種“Furore”和“Ornella”非洲菊切花為試驗材料，探討外加乙烯、乙烯抑制劑及保鮮液對切花瓶插壽命之影響。非洲菊切花以外加0.1～10 ppm 乙烯處理24小時雖會刺激呼吸率和乙烯釋放量之增加，但對瓶插壽命影響並不顯著。以乙烯抑制劑胺基三唑 (aminotriazole; ATA) (1.2mM)、1-甲基環丙烷 (1-methylcyclopropene; 1-MCP)(1800 ppb)、Retain (100 ppm) 和硫代硫酸銀 (silver thiosulfate; STS) 處理，亦無法延長其瓶插壽命，顯示非洲菊為對乙烯不敏感之切花，且乙烯並不是影響非洲菊切花老化之主要因素。以1,3-二氯- 5,5-二甲基乙內醯脲 (1,3-dichloro-5, 5-dimethylhydantoin; DDMH)、NiCl2配合蔗糖之保鮮液預措2小時，能有效的延長非洲菊切花瓶插壽命，其中“Furore”非洲菊以1.25 ppm DDMH + 250 ppm NiCl2 + 0.25% 蔗糖之效果最佳，“Ornella”非洲菊以25 ppm DDMH + 500 ppm NiCl2 + 0.5% 蔗糖最佳，皆可增加約4天之瓶插壽命。此外，亦探討保鮮液預措後對切花之吸水性、鮮重變化、呼吸率和乙烯釋放量之影響。The vase life of “Furore” and “Ornella” gerhera cut flowers treated with preservatives and exogenous ethylene at 0~10ppm concentrations were studied. Meanwhile, the water uptake, fresh weight change, respiration rate, and ethylene production of gerbera cut flower pulsed with preservative treatment were investigated. Ethylene all concentrations of tested increased the respiration rate and ethylene production of the treated flower, but not significantly affected their vase life. Pulse treatment with ethylene inhibitors, including aminotriazole (ATA) (1.2mM), 1 -methylcyclopropene (1-MCP) (1800ppb), retain (100ppm) and silver thiosulfate (STS) (0.1~2.0 mM), had no effect on prolong of the vase life of gerhera cut flower. The results showed that the cut flowers of gerbera were not sensitive to ethylene, and their senescence was not caused injury by ethylene. The vase life of these two cultivars prolonged for 4 days after pulse treatment with 1,3-dichloro-5, 5-dimethylhydantoin (DDMH), NiCl2 and sucrose for 2 hours. The best effect was obtained with the treatment of combination of 1.25 ppm DDMH, 250 ppm NiCl2 and 0.25% sucrose for “Furore” and treatment of combination of 25 ppm DDMH, 500 ppm NiCl2 and 0.5% sucrose for “Ornella”

循环胆红素水平与新诊断非增殖期糖尿病视网膜病变及其危险因素相关性的病例对照研究

目的本研究旨在评估循环胆红素谱［总胆红素（TBIL）、结合胆红素（DBIL）、未结合胆红素（IBIL）］与非增殖期糖尿病视网膜病变（NPDR）的相关性。方法采用病例对照研究设计，通过人工智能眼底相机对2型糖尿病患者视网膜病变情况进行筛查，并由眼科医生进一步阅片确认病例。最终纳入312名2型糖尿病（T2DM）患者（78例新诊断的NPDR患者与234例无糖尿病视网膜病变的T2DM患者进行1：3匹配）。同时收集患者人口学和相关临床资料，检测患者血清胆红素及相关生化指标。结果NPDR患者的TBIL、DBIL和IBIL浓度显著降低（P值分别为0.003、0.001、0.006），且与糖化血红蛋白（HbA1c）水平无关（P值均 &gt;0.05）。在调整了性别、糖尿病病程、HbA1c和收缩压等传统风险因素后，这种关联仍然存在。此外，在血糖控制良好的T2DM患者（HbA1c ≤7%）或无微量白蛋白尿的T2DM患者［尿白蛋白/肌酐比值（UACR） ≤30 mg/g］中，低水平未结合胆红素者的NPDR风险更高，比值比（OR）95%CI分别为3.44 （1.04， 11.38）和2.53 （1.10， 5.82）；在血糖控制不良（HbA1c &gt;7%）或有微量白蛋白尿（UACR &gt;30 mg/g）的T2DM患者中，低水平结合胆红素者的NPDR风险更高，OR 95%CI分别为2.05 （1.09， 3.86）和2.40 （1.14， 5.02）。结论循环胆红素与NPDR的风险呈独立的负相关关系，这可能成为早期预测和防治糖尿病视网膜病变的临床生物标志物
