摘要

玉牡丹及寶蓮花各取嫩枝及半成熟枝沾吲哚丁酸（IBA）0，500，1000及2000 ppm，以蛭石為介質進行扦插，結果玉牡丹嫩芽插以1000 ppm IBA之100%發根率，平均發根數39.8為最高，半成熟枝插以2000 ppm IBA之100%發根率，平均發根數56.3最佳；寶蓮花之半成熟枝以2000 ppm IBA處理73.3%左右的發根率，發根數14.1為最好，嫩枝插僅30%的發根率。玉牡丹半成熟枝扦插介質以蛭石較珍珠石為佳。

This research chose some semihardwood from Medinilla formosana Hayata and M. macnifica Lindl. and dipped them into IBA with 0, 500, 1000 and 2000 ppm respectively. And then we used vermiculite as medium to grow them. The results of this experiment were: (1) The stem buds of M. formosana Hayata, growing in 1000 ppm IBA, got 100% rooting ratio with 39.8 roots on average, The semihardwood of M. formosana Hayata, growing in 2000 ppm IBA, got 100% rooting ratio with 56.3 roots on average was the best one. (2) The semihardwood of M. macnifica Lindl, treating with 2000 ppm IBA, reached about 73.3% rooting ratio and had the most root number of 14.1 The method of stem bud cutting to M. macnifica Lindl, treating with 2000 ppm IBA, was only with 30% rooting ratio. (3) Comparison between two cutting media for the semihardwood M. formosana Hayata stems, vermiculite was better than perlite.
