摘要
[目的]研究4种桃砧木品种硬枝扦插生根情况。[方法]对4种桃砧木品种进行硬枝扦插生根试验，研究不用砧木品种、通气处理、生根剂浓度处理对其扦插生根的影响。[结果]4个砧木品种中，筑波6号生根率最高，其次是GF677，GF43最低；愈伤组织形成均较多，黑姑娘100％形成愈伤组织，筑波6号次之（87％），GF677最低（24％）；扦插30 d后统计均无腐烂情况；通气处理后愈伤组织形成的数量和生根率均有所增加，其中筑波6号最高，GF677次之，GF43最低；ABT生根剂50 mg／L浸泡后生根率和愈伤组织均最高，分别为83％和100％，150～250 mg／L的生根率较低，仅为1％～5％。[结论]4种桃砧木品种中，筑波6号的生根率最高，黑姑娘最容易形成愈伤组织，GF677的生根率和愈伤组织最低。
Objective] To research the growth situation of hardwood cuttage rooting of four varieties of peach rootstocks.[Method] Hardwood cuttage rooting test was carried out for four hardwood cuttage rooting.Effects of rootstock, aeration treatment and rooting agent concentration on cutting rooting were researched.[Result] Among the four rootstock varieties, Zhubo 6 had the maximum rooting rate, followed with GF677, and GF43 was the minimum.Callus formation was relatively more.The formation rate of Heiguniang was 100%, followed with Zhubo 6 （87%）, and GF677 was the minimum （24 %）.After cutting for 30 d, there was no phenomenon of decomposition.After ventilation treat-ment, the callus quantity and rooting rate both increased.Among them, Zhubo 6 was the maximum, followed with GF677;and GF43 was the minimum.After soaking in 50 mg/L ABT rooting agent, rooting rate and callus formation rate were the maximum, which were 83 % and 100%, respectively.150-250 mg/L ABT had relatively low rooting rate, which was only 1%-5%.[Conclusion] Among the four varieties of peach rootstocks, Zhubo 6 has the highest rooting rate; Heiguniang is the easiest to form callus;and GF677 has the lowest rooting rate and callus formation rate.
