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. (...

Bird cherry-oat aphid, (Rhopalosiphum padi /L./ (Hemi-ptera, Aphididae), is a holocyclic host-alternating species in temperate climates between wooden bird cherry, Prunus padus L. (Rosaceae) (winter, primary host) and grasses (summer, secondary hosts). In the spring, the aphid hatches from the winter eggs on P. padus and two wingless generations are developed before appearance of winged spring ...

Flower buds of peach, apricot, and sweet cherry are killed by low temperatures during winter and spring. Frost protection measures used commonly in the spring are applied to freeze protection during the winter in the Yakima Valley of Washington. Critical temperatures change rapidly during winter.

Several plants are used for their decorative effect during winter holidays. This review explores the toxic reputation and proposed management for exposures to several of those, namely poinsettia (Euphorbia pulcherrima), English holly (Ilex aquifolium), American holly (Ilex opaca), bittersweet (Solanum dulcamara), Jerusalem cherry (Solanum pseudocapsicum), American mistletoe (Phoradendron seroti...
