How to preserve ginkgo seeds and what is the probability of survival

1. Storage method

The common storage method for ginkgo seeds is sand storage and stratification, which is conducive to the growth and development of the embryo, and the germination rate of the seeds is also high. The specific operation method is as follows:

1. Wash the seeds with water, spread them out and dry them for 3-5 days, and remove the sand from those with a moisture content below 5%, in a half-and-half ratio, preferably in a layer of 5-10 cm. First put a layer of clean sand, then a layer of seeds, and finally cover with a layer of clean sand.

2. The seeds need to be turned over after about 3-5 days of sand storage, and then turned over again after a week to avoid moldy seeds.

2. What is the probability of survival?

Using this method, the germination survival rate is relatively high, about 15% higher than the general survival rate. Usually, the survival rate of ginkgo seeds is not very high, only about 70%. However, it is not just the seeds that affect the survival rate. The time and method of planting will also affect the probability of survival. It is best to do it in spring and autumn, and the seeds must be germinated before planting, so that the survival rate will be higher.
