- 摘要:
- 选用2种不同基质和4种植物激素,以清水为对照,研究基质及植物激素对枸杞嫩枝扦插效果的影响。结果表明:国产基质培养插穗时,其成活率、生根数显著高于进口基质,但用进口基质培育的扦插苗新枝长、根长、根系重显著高于国产基质。IAA具有明显提高插穗成活率的作用,但对根系的生长发育促进作用不明显,国光生根NAA对插穗成活率促进作用比IAA小,但对根系的生长发育和地上部分的促进作用比较大,国光生根NAA可作为首选药剂,必要时IAA也可以选用。基质与植物激素之间存在着一定的互作效应,如国产基质与IAA结合使用、进口基质与IBA结合使用插穗成活率均较高,但前者比后者高。
- Abstract:
- Two different substrates and four plant hormones were chosen,and water as CK,soaked and handled the ‘Ningqi No.1’as softwood cuttings,the effect of different substrates and plant hormones on Chinese wolfberry shoots cuttings were studied.The results showed that the survival rate and the root number of wolfberry softwood cuttings were significantly higher when used domestic substrate than import domestic,but the length of new branch,the root length and the root weight were higher when used import substrate than domestic substrate.IAA could significantly improve the survival rate of wolfberry cuttings,but had little effect on root growth.Guoguang rooted NAA had less promoting effect on the survival rate than IAA,but compared to IAA,it had lager effect on root growth and development,and on overground part than IAA.Guoguang NAA could be the preferred agents,when necessary we could choose IAA.There were certain interacted effects between substrate and the plant hormones.If used domestic substrate combine with IAA,and import substrate together with IBA,the survival rate of wolfberry softwood cuttings were relatively high,but the former were higher than the latter.
