银杏(Ginkgo biloba L.)是现存种子植物中最古老的孑遗植物,被称为“活化石”,为我国特产。不仅是广泛栽培的经济树种,也是优良的用材树种,同时又是优美的观赏树种。 银杏种子可供食用和药用,是我国传统的出口商品。由于银杏是雌雄异株植物,若不加选择的栽培,往往影响产量的提高。因此,如何用一些生化指标进行性别预测,以决定取舍,作到按性别比例栽植,是提高产量的重要措施之一。
Ginkgo biloba L. is the oldest relict plant among the existing seed plants. It is called “living fossil” and is a special product of our country. Not only is widely cultivated economic species, but also excellent timber species, but also a beautiful ornamental tree species. Ginkgo seeds for food and medicine, is China’s traditional exports. Because ginkgo is a dioecious plant, if you do not choose the cultivation, often affect the yield increase. Therefore, how to use some biochemical indicators for gender prediction to decide the trade-offs and to do the planting according to the sex ratio is one of the important measures to increase the output.
