不同处理对罗布麻种子生理特性的影响

Effect of Different Treatments on the Physiological Characteristics of Apocynum venetum L. Seeds

[目的]为罗布麻有性繁殖率的提高提供一定的数据参考。[方法]不同储存时间、不同土壤pH值、不同生长调节剂、不同温湿度和光照处理罗布红麻种子,对其发芽率进行比对。[结果]罗布麻种子新采收时,温度25℃,在微碱性土中,经密闭限氧透光条件下发芽率最高,并且赤霉素和萘乙酸对其种子的发芽率均有调节性,但生长调节剂浓度过高会抑制其发芽率。[结论]不同处理对罗布麻种子生理特性的影响显著不同。

[ Objective ] The research aimed to provide certain reference basis for increasing the sexual reproduction rate of Apocynum venetum. [ Method ] The effects of different storage time, different soft pH value, different growth regulators, different temperature and humidity and light on the germination rate of Apocynum venetum L. were compared. [ Result ] The germination rate of Apocynum venetum L. seeds was highest under the conditions of 25 ℃, slight alkaline, closed and the limited oxygen transmission. Gibberellin and NAA had the regulatory effects on the seed germination rate. But the growth regulators at too much higher concentration would inhibit the germination rate. [ Conclusion] The effects of different treatments on the physiological characteristics of Apocynum veaetum seeds were significantly different.
