砧木種類對玫瑰花切花產量與品質的影響

Effect of Rootstock on the Productivity and Quality of Rose Cut Flowers

本試驗是以台灣主要切花品種'Samantha', 'Pitica', 'Labdira'以及'Princess Caroline'為接穗；砧木品種則有Rosa indica 'Major', R multiflora, R. odorata以及R. odorata 'Thornless'。二者利用芽接接插法繁殖後，探討砧木種類對嫁接苗所生產的切花之產量與品質的影響。試驗植株在栽培五個月後開始採收切花。在8個月的切花生產中，'Samantha'、'Pitica'以及'Landora'接穗接於R. odorata或R. odorata 'Thornless'的嫁接苗，產量較扦插苗高。但'Princess Caroline'品種則以扦插苗的產量最高。嫁接苗所生產的切花之花蕾長度，與扦插苗無異但品質指數卻有相當差異。'Samantha'和'Pitica'品種嫁接於R. odorata和R. odorata 'Thornless'所生產的切花品質最好。'Landora'品種嫁接於R. odorata 'Thornless'的嫁接苗所生產的切花品質優於扦插苗。'Princess Croline'品種，則扦插苗所生產的切花品質最好。

The effect of rootstock on the productivity and quality of rose cut flower was studied by budding cvs. 'Samantha', 'Pitica', 'Landora' or 'Princess Caroline' on Rosa indica 'Major', R. multiflora, R. odorata or Rosa odorata 'Thornless' rootstock.After planting for 5 months, budded plants began to harvest cut flowers. In 8 months of harvest, on cultivars of Samantha, Pitica, and Landora plants budded on R. odorata or R. odorata ' Thornless' produced more cut flowers than cutting plants did. Furthermore, the flowers of better quality was produced by budded 'Samantha' or 'Pitica' on R. odorata or R. odorata ' Thornless'. The flower quality of budded 'Landora' on R. odorata 'Thornless' was better than cutting plant. However, on cultivar of Princess Caroline, cutting plants produced more cut flowers of higher quality index than budded plants did.
