How to store fresh apricot pollen and how to preserve almond flour

The results of 5, 20 and 30 apricot pollen showed that the pollen germination rate and high vigor pollen ratio increased with the decrease of temperature. 5 Conditions: The two pollen can be effectively stored for 2 months, and the germination rate of apricots can still reach 5 8 after 6 months of storage.

20 and 30 conditions can preserve pollen for about a year, and for the same variety, the two temperatures have little effect on pollen viability. The results showed that as long as the water content was suitable, the pollen could be directly injected with LN2 without pretreatment, and the high germination rate of pollen could be maintained at the thawing temperature of 37, but the thawing effect of pollen 37 with high water content was better.

There was no significant difference between the pollination and seed setting rate of LN2 and that of fresh pollen after one year of storage.

After removing the collected anthers, lay them on the smooth paper, and put them in a room where the temperature is kept at 20 25 and the humidity is kept at 60% and 80% (the indoor heat and dryness will affect the anther cracking), after 24 hours, the anthers will crack and let go of the pollen, wait for a little drying, collect the pollen and put it in a glassware, and store it in a homemade drying dish for later use. The drying dish can be made by homemade, you can use a paper tube or an iron cylinder, put some quicklime at the bottom of the cylinder, lay paper on the lime, fill the paper with pollen, and cover the cylinder mouth.
