臺灣地區紫色狼尾草農藝性狀變異之研究
Study on diversity of agronomic traits of purple napiergrass in Taiwan
摘要
紫色狼尾草為本土狼尾草原生品系之一。本研究收集自臺灣15縣市共69個樣品，調查紫色狼尾草開花期之最上葉領株高、葉尖株高、莖徑長、莖徑寬、葉片數、劍葉葉片長、劍葉葉片寬、葉緣毛群寬、葉緣毛群高度、葉鞘毛群長、葉舌毛群高、葉痕毛群高、莖節數和節間長等共14項農藝性狀，每樣品調查3次，樣品間之農藝性狀數據，利用統計分析農藝性狀間之變異。結果顯示，14項農藝性狀彼此皆有顯著性的差異，分析性狀間彼此之相關係數，絕大部分性狀間呈現顯著性相關，如莖徑寬與葉數呈顯著正相關（P＜0.05）；葉領株高與葉尖株高、莖徑寬、莖徑長、葉數、劍葉葉長、劍葉葉寬、葉緣毛群高、葉緣毛群寬、葉痕毛群高、節數及節間長呈極顯著（P＜0.01）正相關；節數與劍葉葉長（r=-0.31）及葉緣毛群高（r=-0.32）呈極顯著之負相關。綜合上述，紫色狼尾草由14項農藝性狀調查間之相關大部分、均達顯著之正相關或負相關，某些性狀可做為良好分類依據，如節數與葉緣毛群之負相關關係，爾後可依選拔目標對特定性狀進一步調查，以利育成新品種。

Purple napiergrass is a subspecies of Pennisetum purpureum. The 69 samples of purple napiergrass, collected from 15 counties in Taiwan, were determined the diversity using agronomic traits in this study. The present experiment evaluated 14 agronomic traits, i.e. toppest height of last leaf collar (THC), plant height of leaf tip (PHL), length of stem (LS), width of stem (WS), number of leaves (NL), flag leaf length (FLL), flag leaf width (FLL), height of leaf margin pubescence (HLMP), width of leaf margin pubescence (WLMP), length of leaf sheath pubescence (LLSP), height of leaf ligule pubescence (HLLP), height of leaf scar pubescence (HLSP), number of nodes (NN), length between nodes (LN). Three plants were determined for each sample. The result showed that the 14 agronomic traits were significantly different among samples. Most of the correlation coefficients between the agronomic traits showed significant correlations (P ＜ 0.05). The correlation coefficients between WS and NL showed significantly positive correlation. Further, those between THC and PHL, LS, WS, NL, FLL, FLW, HLMP, WLMP, HLSP, NN and LN showed significantly were positive correlations (P ＜ 0.01). The correlation coefficients between NN and FLL and HLMP were significantly negative with -0.31 and -0.32, respectively. Therefore, the correlation coefficient between NN and HLMP might be used as the selection index for purple napiergrass breeding.
