摘　　要：[Objective] This study aimed to investigate the influence of different plant growth regulators on apricot pollen germination and pollen tube growth. [Method] Pollens of six kinds of Xinjiang apricots were cultured in solid media supplemented with five plant growth regulators （GA3 , NAA, 2, 4-D, 6-BA, IAA）. Then the rate of pollen germination and the length of pollen tube were respectively measured. [Result] In a certain concentration range, GA3 most significantly promoted the pollen germination and the pollen tube growth of Shushanggan, Kalayulvke, Dayoujia, Yiliakeyulvke and Kabakehuanna; NNA had the strongest improvement function on Kumaiti’s pollen germination and pollen tube growth. [Conclusion] All the five plant growth regulators promoted the pollen germination and the pollen tube growth of apricots at low concentration but inhibited them at high concentration.[目的]为了解不同植物生长调节剂对杏花粉萌发和花粉管生长的影响。[方法]在固体培养基中加入植物生长调节剂(GA3、NAA、2,4-D、6-BA和IAA)对6个新疆杏品种花粉进行离体培养,测定花粉萌发率和花粉管长度。[结果]在适宜的浓度范围内GA3对树上干、阿克玉吕克、大尤佳、伊犁阿克玉吕克和卡巴克胡安娜花粉萌发和花粉管生长促进作用最大;NAA对库买提花粉萌发和花粉管生长促进作用最大。[结论]5种植物生长调节剂在低浓度条件下促进杏花粉萌发和花粉管生长,高浓度下抑制。
