蒙古扁桃种子萌发生理研究

探讨了蒙古扁桃种子萌发生理。实验结果表明 ,成熟的蒙古扁桃种子胚形态和生理发育完全 ,种皮含有萌发抑制物质。在 1 7°C下蒙古扁桃种子萌发率较高 ,光可以促进蒙古扁桃种子萌发。用 2 %PEG 60 0 0、0 .5 %NaHCO3 、0 .1 %NaCl、0 .2 %NaCl和 5 0 μg/mLNAA浸种处理均促进蒙古扁桃种子萌发 ,而 5 0 μg/mL 6 BA浸种处理对蒙古扁桃种子萌发有抑制作用。

Study on seed germination's physiology of Prunus mongolica Maxim

The seed germination physiology of Prunus mongolica Maxim was studied. The results showed that the embryo of Prunus mongolica Maxim's mature seeds have completed its morphological and physiological development,the water and air could pass through its endocarp,its tasta contained some seed germination inhibitor. The experiment proved that Prunus mongolica Maxim seed germination percentage was higher at 17 °C than that was at 20 °C,the light could promote its seed germination,soaking with 2% PEG-6000,0.5% NaHCO3,0.1% NaCl,0.2% NaCl and 50 μg/mL NAA could promote its seed germination,but 50 μg/mL 6-BA inhibited its seed germination.
