| 摘 要： | 本文研究了不同浓度银杏外种皮提取物浸种对小麦、玉米、大豆萌发和幼苗生长的影响.结果表明:低浓度提取物可提高小麦、大豆和玉米种子的萌发率、发芽率;促进幼苗地上和地下部分生长,其中作用最明显的为500倍提取物的稀释液.在萌发期,500倍稀释液浸种液处理:提高小麦和玉米幼苗的淀粉酶和叶绿素的含量,促进大豆幼苗叶绿素和蛋白质含量提高,而高浓度的银杏外种皮提取物稀释液处理则降低小麦和玉米幼苗的淀粉酶和叶绿素的含量,也使大豆幼苗叶绿素和蛋白质含量降低.

| Abstract: | This paper studied the effect of different concentrations of extracts from Sarcotesta of Ginkgo biloba seed soaking on the growth of wheat, corn, soybean germination and seedling. The results showed that： low concentration of extract can improve the wheat, corn and soybean seed germination rate, germination rate ; seedling aboveground and underground part growth, one of the most obvious effect was 500 fold dilution was extract. In the germination stage, 500 times dilution soaking solution： increase the content of wheat and corn seedling amylase and chlorophyll, promote the chlorophyll and protein content of soybean seedlings, and extracts from Sarcotesta of Ginkgo biloba dilution of high concentration treatment decreased content of wheat and maize starch enzyme and chlorophyll, and the chlorophyll and protein content of soybean seedlings decreased. |
