| 中文摘要 | 汁胞異常是柑橘果實常見生理障礙,依形態特徵主要可分為汁胞粒化及汁胞萎縮。本研究調查2012年至2015年海梨柑(Citrus tankan Hayata f. hairi Hort.)果實汁胞異常情形,針對氣溫及降雨量進行探討,並比較汁胞異常果實與正常果實間品質差異。海梨柑中兩種異常汁胞皆會出現,2012年異常發生率及發生程度分別為54.8%及30.1%,當年降雨量為4年中最高;而2014年異常發生率及程度分別為25.4%及17.3%,降雨量則最少。2012年至2014年汁胞粒化發生率高於汁胞萎縮,而2015年則以汁胞萎縮發生率高於汁胞粒化,當年年均溫度為4年中最高。汁胞粒化果實較正常果實大且果皮率高,可溶性固形物、可滴定酸及果汁率則隨汁胞粒化程度增加而逐漸降低,但果肉含水率有增加趨勢;而汁胞萎縮果實大小及果皮率與正常果實無顯著差異,且果肉含水率較低,推測導致海梨柑兩種汁胞異常發生的原因及機制並不完全相同。 |
| 英文摘要 | Juice vesicle disorders are common physiological disorders in citrus. There are two basic types of disorders based on morphological characters, the granulation and the vesicles collapse. This study aimed to investigate the effect of rainfall and temperature in juice vesicle disorders of haili tangor (Citrus tankan Hayata f. hairi Hort.) from 2012 to 2015 and the comparison of normal, granulated and vesicles collapsed fruits. Both disorders were present in haili tangor. The incidence and degree of disorders were 54.8% and 30.1%, respectively in 2012, and the annual rainfall was the highest; while in 2014 when the annual rainfall is the lowest, they were 25.4% and 17.3%, respectively. In disorders occurred from 2012 to 2014, the granulation is higher than vesicles collapse, whereas the occurrence of vesicles collapse was higher in 2015, with average annual temperature in recorded high since 2012. The average size and peel proportion of granulated fruits was significantly higher than non-granulated fruits. The total soluble solid, titratable acidity and juice content were declined gradually over the period of granulation, however, the granulated pulps contained higher moisture content than the healthy ones. By contrast, there were no significant differences between vesicles collapsed and normal fruits in fruit size and peel proportion, and the pulps moisture content was lower in vesicles collapsed pulps than in healthy pulps. The results suggest that the causes and mechanisms of said two-type vesicle disorders are not completely the same. |
