Drying seeds to appropriate relative humidity is the first step to long term seed storage. NLGRP and CPC recommend drying seeds to 25-35% relative humidity at room temperature. One way to acheive specific relative humidities is to use saturated salt solutions. Here, Lisa shows the steps of creating a saturated salt solution from Magnesium Chloride Hexahydrate (Cl2H2MgO6) or Potassium Acetate (CH3CO2K). She also demonstrates the equipment needed to create dessication chambers of various sizes.

Difficulty cleaning arctostaphylos seeds

I’m having difficulty removing the fruit from different species of manzanita after field collection. Does anyone have any tips for processing/cleaning these seeds? How necessary is it to remove the pulp (versus letting it dry) for short-term storage? Long-term storage?

Heather Schneider, Santa Barbara Botanic Garden

In the fall of 2017, Dr. Heather Schneider from the Santa Barbara Botanic Garden attended the Kew Millennium Seed Bank Partnership’s three-week Seed Conservation Techniques Training Course. The course brought together conservationists from all over the world to improve conservation seed banking practices used by MSB partners. The course covered a variety of topics from seed biology to field work to processing and storage. At the end of the course, students were encouraged to create an action plan for improving their own seed bank techniques at home. Dr. Schneider will discuss some lessons learned and changes implemented at the Santa Barbara Botanic Garden resulting from this course.
