用浓硫酸处理窄叶野豌豆种子的发芽试验

窄叶野豌豆种子存在硬实现象,硬实种子不透水,在不经过处理的情况下,发芽率极低(8%)。为提高窄叶野豌豆种子的发芽率,采用98%的浓硫酸对窄叶野豌豆种子进行浸种处理。通过在不同温度下进行发芽可知,窄叶野豌豆种子发芽最适温度为10℃。在10℃温度条件下,经浓硫酸浸种处理10 min的种子发芽率达到100%,发芽势达到82%。用浓硫酸处理5~50 min的种子平均发芽率为95.8%,平均发芽势为68%;而不经浓硫酸处理的空白对照试验组发芽率仅为8%。

Germination Test on Vicia angustifolia Linn. ex Reichard seeds with concentrated sulfuric acid

The hard seeds of Vicia angustifolia Linn. ex Reichard are impermeable. Under non-treated conditions, the germination rate is very low （8%）. To improve the seed germination rate, 98% concentrated sulfuric acid were used for Vicia angustifolia seed soaking treatment. The germination treatments in different temperatures were carried out. Results indicated that the optimum temperature for Vicia angusfifolia seed was 10℃. Under conditions of 10℃, after 10 min soaking by concentrated sulfuric acid, the germination rate reached 100%, and the germination potential reached 82%. After 5 -50 min soaking by concentrated sulfuric acid, the germination rate was 95.8% on average, and the germination potential was 68% on average. And for the blank control without concentrated sulfuric acid, the germination rate was 8%.
