Effect of Different Factors on Rooting Characteristics and Survival of Lonicera japonica Thunb

不同因子对金银花生根特性及成活的影响(英文)

[Objective] The aim was to explore the effects of different factors on rapid propagation and seedling survival of Lonicera japonica Thunb. [Method] The cuttings of 1, 2 or 3 years old, with different length, were soaked in different hormones at different concentrations for different time and planted at different dates. Finally, their rooting rate and survival rate in different treatments were measured and compared. [Result] The rooting rate and survival rate of one-year old cuttings with length of 10-13 cm and planted on September 20 and October 20, 2012 were relatively higher among all the treatments. Hormone treatment could significantly promote the callus formation and accelerate the rooting of the cuttings, and improve their survival rate. The cuttings treated with 120-200 mg/L ABT1 or NAA for 35-45 min had higher rooting rate and survival rate. Among them, the survival rate of cuttings treated with 160 mg/L ABT1 for 35 min was the highest, up to 92.5%. [Conclusion] The study provided basis for improving the survival rate of L. japonica by cuttage, and for optimizing the rapid propagation technique.

目的是在快速的繁殖和忍冬装饰用的梨树 Thunb 的幼苗幸存上探索不同因素的效果。与不同长度， 1， 2 或 3 岁的剪样在不同时间在不同集中在不同荷尔蒙被浸泡并且在不同日期种了。最后，他们在不同处理的 rooting 率和幸存率被测量并且比较。[结果] rooting 率和幸存与一些 10-13 厘米一个年评估旧剪样并且在 9 月 20 日种了， 2012 年 10 月 20 日在所有处理之中是相对更高的。荷尔蒙处理能显著地支持胼胝形成并且加速剪样的 rooting，并且改进他们的幸存率。与 120-200 mg/L ABT1 或 NAA 对待 35-45 分钟的剪样有更高的 rooting 率和幸存率。在他们之中，为 35 与 160 mg/L ABT1 对待的剪样的幸存率纪录最高，直到 92.5% 。学习为改进 L 的幸存率提供了基础。由插木繁殖法的装饰用的梨树，并且为优化快速的繁殖技术。
