中文摘要 | 為了解細本山葡萄的選種反應,於1999年與2000年在臺中進行試驗,以10個細本山葡萄及2個細葉山葡萄的品系作為材料。調查其根部性狀等農藝特性,以比較其外表型變異。田間設計採RCBD 3重複,2種不同土壤水分含量,調查11個性狀及計算其9個性狀之相關。大多數的性狀包括根產量和主根直徑均顯示具有遺傳型和外表型的變異,湛水處理顯著地降低了根產量和其他影響根產量的性狀,然而,山葡萄根的β-sitosterol成分含量卻無顯著改變。遺傳型和外表型相關的結果為:根產量和主根直徑、主莖直徑、株高、分枝重等呈顯著之正相關,正常灌水條件下,根產量和β-sitosterol成分含量、主莖直徑呈顯著之正相關,但以上的相關係數在湛水情況下降低且不顯著,在湛水的情況下,分枝數目與重量與根產量具顯著正相關。 |
英文摘要 | To understand the response of selection of Vitis thunbergii, We comared phenotypic variation and correlations among agronomic characters including root production. Two field experiments were conducted in 1999 and 2000 at the experiment field of TARI (Taichung). Ten Lines of Vitis thunbergii Sieb.et. Zucc. var. taiwaniana and two Vitis adstricta Hance were grown in two randomized complete block designs with three replication. Two experiments differed in respect to irrigation regime. The values of eleven characters and relationships of nine characters were assessed. Most of the characters including root yield and main stem diameter showed considerable genotypic and phenotypic variations. Water flooding significantly decreased root yield and its components, however, β-sitosterol content did not differ significantly. Genotypic and phenotypic correlations revealed that root yield had significant positive correlations with main root diameter, main stem diameter, plant height branch weight and main stem weight under normal irrigation. Root yield had significant correlations witih β-sitosterol content and main stem diameter under normal irrigation regime, while these correlations became insignificant under water flooding conditions. |
