摘要：

为筛选适宜的百香果扦插方案，提高扦插成活率，以‘壮蜜05’、‘台农1号’枝条为插穗，从外部形态和解剖结构观察插穗不定根的形成过程，研究扦插时期、空气温湿度、生根剂浓度、枝条节位对插穗生根的影响。结果表明，百香果扦插生根属于潜伏根原基生根类型。扦插后6~9 d形成愈伤组织，9~12 d插穗基部凸起形成白色根点，12~15 d长出不定根。短时间的高温对百香果扦插生根影响较小，适当范围内温度越低越有利于扦插生根。干湿交替的环境有利于百香果扦插生根。‘壮蜜05’适宜在3月15日插穗浸泡300 mg/L生根粉1 h后扦插，第7节位的扦插生根效果最佳。‘台农1号’适宜在3月15日、12月15日扦插，插穗不做处理或浸泡100 mg/L生根粉1 h后扦插，第5~10节位的扦插生根效果均较好。

Abstract:

In order to get the proper cuttage cultivation scheme of passion fruit, variety ‘Zhuangmi 05’ and ‘Tainong 1’ were used as the scion to observe the formation process of adventitious roots of cuttings from the morphology and anatomical structure, and study the effects of cutting time, air temperature and humidity, rooting agent concentration and branch node position on rooting. The results showed that passion fruit root was formed from latent root primodia. Callus was formed 6-9 days after cutting, white root spots were formed at the base of cuttings from 9-12 days, and adventitious roots grew from 12-15 days. Short time high temperature had little effect on cuttage rooting of passion fruit, and the lower the temperature in the appropriate range, the more conducive to cuttage rooting. The alternate dry and wet environment was conducive to the rooting. ‘Zhuangmi 05’ was suitable for cutting after soaking 300 mg/L rooting powder for 1 h on March 15, and the cuttage rooting effect of the 7th node was the best. ‘Tainong 1’ was suitable for cutting on March 15 and December 15 without treatment or after soaking 100 mg/L rooting powder for 1 h. The rooting effects of the 5th to 10th nodes were better.
