Under normal circumstances, it is easy to distinguish between male and female ginkgo trees, which can be distinguished by the appearance of leaves, the shape of inflorescence and the shape of crown, but it may be because of grafting that these ginkgo trees in front of my house are a little out of line, which makes me a little confused.
Identification of male and female ginkgo trees under normal circumstances 1. Identification by leaves
We all know that the leaves of ginkgo trees are fan-shaped, but the leaves of their male and female trees are different. Normally, the leaves of female trees are round and full, while the leaves of male trees are generally long and narrow, and there will be some gaps in the leaves, usually with a big gap in the middle.
Second, identify by inflorescence
The flowers of the male tree will have a bunch of long inflorescences, as shown below, which are a bit like mulberries, but thinner. The flowers of the female tree are a bit like matchheads, and they will not be strung, each of which is separate and forms a group of inflorescences.
Third, through the crown identification
Generally speaking, the crown of the female tree is rounder, and the crown of the male tree is more straight and tapering, that is, the branches of the male tree are smaller and denser, while the crown of the female tree is larger and the branches are flatter.
As mentioned earlier, there are five ginkgo trees in front of my house, two of which are female trees with fruit, and the other three are male trees. The method mentioned above is a theoretical method to identify male and female, but in fact, it may be because of grafting that there are some special places in these five ginkgo trees in front of my house.
First, the sprouting seedlings of female trees are male trees. The following picture shows the sprouting seedlings of a female tree. We can see from the leaves that there is a gap in the middle, which belongs to the leaf characteristics of male trees. This should be the reason for grafting. We can understand.
