桃半成熱枝扦插繁殖

Rooting of Semihardwood Cuttings of Peach

在網室中進行噴霧扦插繁殖，以IBA 2,500ppm及將插穗基部行削皮創傷，可促進桃半成熟枝，單芽，二芽，三芽扦插枝發根。培養介質以蛭石對發根之效果最佳。本試驗結果提供桃密集栽培時，生產大量經濟苗木之途徑。

In the mist propagation system, peach semihardwood single-bud, two-bud or three-bud cuttings have been successfully rooted. Combination of 2500ppm IBA concentrate dip basal wound, and vermiculite (No.2) as rooting medium showed high rooting percentage for semihardwood cuttings. Thi results showed that the massive and inexpensive source of nursery trees for high density planting of peachs such as meadow orchard was possible.
