| 摘 要： | 以园土、河沙、自来水为基质,就不同浓度生根粉处理对西番莲(Passiflora caerulea Linn.)枝条在不同基质中扦插生根的影响进行了研究.结果表明,3种基质中以园土的效果最好,成本低,插穗生根率高,且侧根发达;河沙的效果最差,插条愈伤组织发生早,但基本不分化;以自来水为基质的插条发根迟,侧根少,根色发白.不同浓度生根粉处理的插条在不同基质中生根效果差异显著,其中以200 mg/L生根粉处理的插条在园土基质中的生根总体效果最好,生根率高达86.67%.

| Abstract: | Effects of different substrates such as garden soil , river sand , tap water and rooting powder of different concentrations on cutting rooting of Passiflora caerulea Linn.were studied .The results showed that garden soil was the best substrates with low cost , high rooting rate and developed lateral root;river sand was the worst substrate for cutting rooting of Passiflora caerulea Linn., with the callus formation in the cutting early , but almost no differentiation;the cuttings rooted late , lateral roots were few and white when the tap water was used as a substrate .The rooting rate of cuttings treated with different concentra-tions of rooting powder and different substrates was significantly different , of which , cuttings treated with 200 mg/L rooting powder and the garden soil as the substrate was the best , with the rooting rate of 86.67%. |
