Cryopreservation of Vegetative Dormant Winter Buds
Cryopreservation of vegetative winter buds is an alternative method to preserving plant species in the field. In this method, nodal sections of scionwood are stored in liquid nitrogen vapor. Cryopreservation of the vegetative dormant winter buds involves low maintenance costs and virtually eliminates the risk of germplasm loss. At the NCGRP, this method is routinely used to preserve Malus sp. (...
متن کاملCryopreservation of dormant buds from diverse Fraxinus species.
Ash (Fraxinus) is an economically important tree genus in the landscape industry, as well as a key component of North American forests, especially in the North Central United States and adjacent regions in Canada. In recent years, the Emerald Ash Borer beetle (Agrilus planipennis) has significantly threatened the survival of native North American Fraxinus species. A dormant-bud cryopreservation...
متن کاملCryopreservation of Populus trichocarpa and Salix dormant buds with recovery by grafting or direct rooting.
BACKGROUND Methods are needed for the conservation of clonally maintained trees of Populus and Salix. In this work, Populus trichocarpa and Salix genetic resources were cryopreserved using dormant scions as the source explant. OBJECTIVE We quantified the recovery of cryopreserved materials that originated from diverse field environments by using either direct sprouting or grafting. MATERIAL...
متن کاملCryopreservation of Salix species using sections from winter vegetative scions.
Twigs of Salix species are candidates for cryopreservation procedures because they become tolerant of freezing temperatures during mid-winter. We examined several variables in developing a two-step cryopreservation procedure for sections from these twigs. Samples of Salix triandra cooled to -30 or -35 degree C and then transferred to the vapor phase over liquid nitrogen gave the greatest percen...
