为探究植物生长调节剂对抗逆菊扦插苗生长的影响,本研究使用植物生长调节剂处理黄花、粉花的抗逆菊扦插苗,以清水处理黄花抗逆菊为对照(CK),测定其冠幅、株高等地上生长指标,根长、根幅等地下生长指标,地上生物量及地下生物量,并进行主成分分析和结构方程模型分析。结果表明,在一定浓度范围内的植物生长调节剂对该植物的生长发育具有一定的促进作用,与黄花抗逆菊相比,粉花抗逆菊对植物生长调节剂表现出更高的敏感性。植物生长调节剂处理后的粉花抗逆菊叶数、根幅较黄花抗逆菊分别增加16.3%、23.2%;黄花抗逆菊地上生物量、地下生物量较CK分别增加1.3倍和1.4倍。粉花抗逆菊的地上部分、黄花抗逆菊的地下部分对植物生长调节剂的响应较为明显。主成分分析表明,抗逆菊的地上部分生物量对植物生长调节剂的响应较为明显。结构方程模型显示,抗逆菊的地上生物量主要受冠幅和叶数的直接影响,而地下生物量主要受根长的直接影响。

To investigate the effects of plant growth regulators on the growth of cuttings of adversity-resistant Chrysanthemum,plant growth regulators were used to treat the cuttings of yellow-flowered and pink-flowered chrysanthemums with resistant conditions, and the yellow-flowered and adversity-resistant Chrysanthemum treated with clear water were used as the control (CK), the crown width, plant height above ground growth indicators, root length, root width and other underground growth indicators, above ground biomass and underground biomass were measured, principal component analysis and structural equation model analysis were conducted. The results showed that plant growth regulators can promote the growth and development of the plant. Compared with yellow flowers, pink flowers showed higher sensitivity to plant growth regulators. After treatment with plant growth regulator, the leaf number and root width of pink flower were increased by 16.3% and 23.2%, respectively, compared with yellow flower. Compared with CK, the aboveground biomass and underground biomass increased 1.3 times and 1.4 times, respectively. The response of aboveground part of pink flower and underground part of yellow flower were obvious to plant growth regulators. Principal component analysis showed that the aboveground biomass of adversity-resistant Chrysanthemum had obvious response to plant growth regulators. The structural equation model showed that the aboveground biomass was directly affected by crown width and leaf number, while the underground biomass of adversity-resistant Chrysanthemum was directly affected by root length.
