由單節扦插苗，芽接扦插苗和微體扦插苗生產迷你玫塊盆花

The Production of Potted Miniature Rose by Single-node-cutting, Budded-cutting and Microcutting

本文比較經由單節扦插、芽接後扦插和微體扦插繁殖所產生之迷你玫瑰的盆花品質。Royal Sunblaze品種，每盆栽植一株芽接扦插苗或微體扦插苗一株或三株單節扦插苗，在扦插後16週其盆花的高度與樹冠直徑的比值都可達到標準比值1.5。栽植Royal Sunblaze的芽接扦插苗，其盆花植株高度較栽植微體扦插苗長成的盆花植株高。而且芽接扦插苗發育較多基部芽、花朵以及較大的樹冠陰影面積。Red Sunblaze品種，每盆栽植一株單節扦插苗或微體扦插苗，在扦插24週後都可發育成具商品價值的盆花。芽接扦插苗，由於植株過於高大反而未能發育成具商品價值的盆花。雖然，其樹冠陰影面積與單節扦插苗或微體扦插苗的樹冠陰影面積並無差異。

The quality of potted miniature rose, cvs. Royal Sunblaze and Red Sunblaze propagated by single-node cuttings, budded-cuttings, and microcuttings was compared. One budded cutting, one microcutting, one or three single-node cuttings of 'Royal Sunblaze' per pot achieved the standard ratio of pot plant height to diameter (1.5) of canopy shading area (CSA), 16 weeks after cutting. Budded cuttings of potted 'Royal Sunblaze' were taller than those from microcuttings. Furthermore, budded cuttings developed more basal shoots, flowers and canopy shading area than microcuttings and single-node cuttings. Twenty four weeks after cutting, one microcutting and one single-node cutting of 'Red Sunblaze' per pot developed into a commercial standard pot rose. In contrast, budded cuttings never developed into a commercial pot rose, because they were too tall. The canopy shading area of budded 'Red Sunblaze' budded-cutting was not significantly different from those of single-node cuttings or microcuttings.
