中文摘要 | 為改善臺農2號番木瓜扦插苗之根系,以穴植管及2.5吋盆進行扦插苗容器育苗之比較,結果顯示穴植管苗根系中10 cm及15 cm以上根數比2.5吋盆苗之根系多,且穴植管苗能培育直立未盤根之根系。為探討市售扦插苗、穴植管扦插苗、2.5吋盆扦插苗及實生苗於田間栽培上之差異,將其定植於田間進行比較,結果顯示扦插苗相較於實生苗能降低開花與結果位置,並能提早2~2.5個月開花與採收。穴植管扦插苗在植株生長及果實品質上與其他兩種扦插苗並無顯著差異,僅結果數高於兩者,然而颱風過後,穴植管扦插苗之植株倒伏率低於其他兩種扦插苗,顯示穴植管扦插苗較具抗倒伏效果。 |
英文摘要 | In order to improve the cutting rooting system and plant development quality, dibbling tube and 2.5-inch plastic pot were used for papaya cuttings propagation in this study. The dibbling tube cuttings had more roots which length ≧ 10cm or 15cm than did the 2.5-inch plastic pot cuttings. The root system of dibbling tube cuttings grew vertically and had no root circling. The true seedlings, market cuttings, dibbling tube cuttings and 2.5-inch pot cuttings of "Tainong No.2" papaya were planted in the field to study the production efficiency of seedlings. The results showed that all those cuttings planted in the field had lower flowering and fruiting position than had true seedlings planted in the field. Also, the timing of first flowering and harvesting of all those cuttings were 2 ~ 2.5 months earlier than that of true seedlings. There was no significant difference in growth characteristics and fruit qualities among three kinds of cutting, but the dibbling tube cuttings planted in the field had more number of fruits than had other cuttings planted in the field. The plants from dibbling tube cuttings was less lodging rate than that of the plants from other two kinds of cuttings. |
