An Improved Cryopreservation Protocol for Mentha spp. Based on Pvs3 as the Cryoprotectant

Autor: A, Senula, D, Büchner, E R J, Keller, M, Nagel

Publikováno v: Cryo letters. 39(6)

Vitrification approaches are widely used to cryopreserve Mentha spp. genetic resources.Here, we compared the response of 20 different Mentha species and hybrids during cryopreservation and elucidated the efficacy of two cryoprotectants.One hundred an

Publikováno v: Genetic Resources and Crop Evolution. 44:509-517

For taxonomic purposes and because many wild relatives of Allium crops are endangered in their native habitat (Sancir et al., 1989), a collection of Allium species was built up in the IPK at Gatersleben. At present it consists of more than 3000 acces

Sucrose, cytokinin, and ethylene influence formation of in vitro bulblets in onion and leek

Autor: E. R. J. Keller

Publikováno v: Genetic Resources and Crop Evolution. 40:113-120

In vitro maintenance of plant organs can enhance programs in plant breeding and germplasm resources. In bulbous plants, such as onion (Allium cepa L.) and leek (A. ampeloprasum L.) induction and storage of in vitro bulblets could enable long term mai
