Family Scientific Name: Solanaceae
Family Common Name: Potato Family
Scientific Name: Lycium berlandieri Dunal
Common Name: Berlandier’s Wolfberry
Ecotype: Madrean Archipelago
General Distribution: Berlandier’s wolfberry is a species typical of the Chihuahuan and Sonoran desert scrub ecosystems found in Northern Mexico and in the United States from Arizona to Texas (Matthews 1994). It grows along washes and on flats, rocky slopes and gravelly hills (Matthews 1994). In Arizona it flowers March-September (Matthews 1994). It is a particularly important food and shelter source for Gambel’s quail and scaled quail, although other birds and rodents utilize it as well (Matthews 1994). Berlandier wolfberry is drought tolerant, losing its leaves and becoming dormant under water stress (Matthews 1994).
Propagation Goal: Plants
Propagation Method: Seed
ProductType: Container (plug)
Propagule Collection: Collect mature berries by hand.
Propagule Processing: Mash the very wet berries with a potato masher, fork, and/or fingers to separate pulp. Follow with a wet ferment (describe) for one week in a gallon jar. Water winnow and rinse through No. 20 sieve.It may be possible to skip the fermenting step and simply separate the pulp after mashing. Further experimentation is needed in the manual seed facility. Hobby sized rock tumblers can also be used to separate the pulp from the seeds (Dreeson 2004). Cleaned seeds should be stored in cool, dry, airtight containers ~5°C (Bonner and Karrfalt 2008).
Establishment Phase: Germination rates of some Lycium sp. increase with cold stratification, although it varies between species and some do not require stratification (Bonner and Karrfalt 2008). Untreated Lycium andersonii seeds have germination rates between 68% and 94% while Lycium barbarum seeds need 60-120 days of cold stratification in moist sand at 5°C to achieve germination results of 74% (Bonner and Karrfalt 2008). Information on germination rates and stratification of Berlandier wolfberry is lacking, so germination tests on untreated and stratified seed of this species would be beneficial. Berlandier wolfberry can also be propagated by cutting (Matthews 1994).
