植物激素和基质对疏花水柏枝扦插繁殖的影响

The Effects of Plant Hormones and Culture Medium of Myricaria laxifflora(Franch.) on Cottage Propagation

通过不同浓度的生根粉、NAAI、BA处理疏花水柏枝插穗,并在清水和河沙中进行暗培养,研究其发芽数、生根数、新枝长、根长、新枝数量和生根数量。结果表明:清水中插穗更容易生根和发芽;河沙基质中,经生根粉2g/L处理后的插穗新枝长和根长最长;河沙基质中,经生根粉0.5g/L处理后的插穗新枝数量最多,经NAA 100mg/L处理后的插穗生根数量最多。

The cottage trials of Myricaria laxifflora （Franch.） were executed. Different growth regulator concentrations oi roo- fing power, NAA and IBA were be used, and the culture medium were water and sand. The burgeon number of quickset, rooting number of quickset, root length and amount, branch length and amount were be record. The results show that： （ 1 ） the water cutting was easier on roofing and burgeon. （2） The shoot length and root length was longest which through rooting power 2g/L treated in sand matrix. （3） In sand matrix, the amount of shoot was most which through ABT 0.5g ! L treated. And NAA 100mg/L treated the quickset the amount of root was most.
