中文摘要 | 本研究運用灰色系統理論分析黃、綠及紫三種甘藷葉片之葉綠素與類胡蘿蔔素相關化合物(chlorophyll- and carotenoid-related compounds)對葉片反射光譜NDVI植生指數之關聯性。灰關聯分析結果顯示,葉綠素與類胡蘿蔔素相關化合物對NDVI之灰關聯序與化合物之極性有顯著相關。在葉綠素相關化合物方面,PPIX、MGPP、Pchlide、Chlideα及Childe b等葉綠素的代謝物質都屬於無植醇鏈之脫植醇色素(dephytylated pigments),其極性較大而易溶於水。而CHl a、Chl b、Phe 及Phe b則都屬於含有植醇鏈之含植醇色素(phytylated pigments),其極性較小而傾向脂溶性。此化學結構的差異造成有植醇鏈的葉綠素相關化合物對葉片反射光譜NDVI之貢獻度較大。對類胡蘿蔔素相關化合物而言,Car對NDVI之貢獻度大於大部分之葉綠素相關化合物,但極性較高之MPCar,對NDVI之貢獻度則大於極性較低之LPCar。 |
英文摘要 | This research applied grey system theory to analyze the correlation between the contents of chlorophyll- and carotenoid-related compounds and the normalized difference vegetation index (NDVI) calculated from the leaf reflectance data of three sweet potato varieties with yellow, green or purple color. The results of grey relational analysis indicate the polarity of chlorophylls or carotenoids is significantly correlated to NDVI. Chlorophylls without phytol chains also called dephytylated pigments such as PPIX, MGPP, Pchlide, Chlide a and Childe b are more polar and located in the stroma. Chlorophylls containing phytol chain also named phytylated pigments such as Chl a, Chl b, Phe a and Phe b are less polar or nonpolar and located in the thylakoid membrane. The less polar carotenoids play more contribution to the NDVI than the more polar carotenoids do. The carotenoid-related compounds play relatively more contribution to NDVI than the chlorophyll-related compounds do. |
