Cryopreservation of pollen

Creator:: Craddock, W. James Hill
Abstract:: Cryopreservation of pollen offers a simple and effective method of long-term pollen storage. Pollen may be stored in liquid nitrogen (LN) for many years without loss of its essential capabilities to pollinate, fertilize, and set normal fruit and seed when used in plant breeding, for controlled pollinations, or for the...

Improvement of cryopreservation regrowth of in vitro Ribes by pretreatment

Creator:: Luo, Jie, 1968-
Abstract:: Improved recovery of cryopreserved meristems and calli from in vitro currant (Ribes aureum Pursh and R. ciliatum Humb. & Bonpl.) plants was obtained by two-hour pretreatment with sucrose, proline, abscisic acid-responsive protein (RABP), and bovine serum albumin (BSA) solutions. Meristems and calli cold-acclimatized for one week were immersed in pretreatment...

Cryopreservation of in vitro-grown apical meristems

Creator:: Chang, Yongjian
Abstract:: Alternating temperature (22°C / -1°C) pretreatments were effective for increasing cold hardiness and recovery of cryopreserved meristems. Combining low temperature pretreatment with abscisic acid (ABA) or sucrose treatments reduced the time required for optimal cold hardiness of meristems. Desiccation tolerance was directly correlated with increased cold hardiness and recovery of...

Cryopreservation of Shoot Tips: Antioxidant Investigations with Rubus and Protocols for Mentha and Vaccinium

Creator:: Uchendu, Esther Eyiuche
Abstract:: Oxidative stress that occurs during cryopreservation may be reduced by the addition of antioxidants. Vitamin E (Vit E), Vitamin C (Vit C), glutathione (GSH), lipoic acid (LA), glycine betaine (GB) and polyvinylpyrrolidone (PVP) were applied at four steps of the PVS2 vitrification protocol (pretreatment, loading, rinsing, and regrowth). Shoot tips...

Relationships between endogenous phenolic compounds of rhododendron tissues and organs and cold hardiness development

Creator:: Chalker-Scott, Linda
Abstract:: The leaching of water soluble phenolic compounds from cold stressed Rhododendron leaves was found to be a reliable indicator of tissue damage. In sublethally stressed leaf tissues, more and novel phenolic compounds appeared and were hypothesized to be precursors of cell wall components such as lignin and suberin. Subsequent radiolabeling...

Frost hardiness of buds, flowers and fruit of pear (Pyrus communis L.)

Creator:: Strang, John George
Abstract:: Spring frost damage to pears in the Pacific Northwest frequently results in substantial crop losses. This research was undertaken to investigate the effects of frost on pear buds, flowers, and fruit through controlled freezing tests and field studies in order to better understand the frost phenomenon and refine frost protection...

The role of glutathione in the development and release of rest on 'Redhaven' peaches

Creator:: Siller-Cepeda, Jorge H.
Abstract:: A rapid and sensitive HPLC method for quantifying both the reduced and oxidized forms of glutathione simultaneously in woody plant tissues was developed. This method was applicable to a variety of woody plant species and different tissues. Total glutathione content in the bark tissue of seven of the woody plant...

Hydrogen cyanamide on triphenyltetrazolium chloride reduction, sulfhydryl group binding, and catalase activity in bromegrass (Bromus inermis Leyss) cells

Creator:: Zhen, Liping
Abstract:: Hydrogen cyanamide (CY) has been used to break rest in temperate crops, but levels used to overcome rest are sometimes toxic to plants. The rest breaking effect of CY is thought to involve peroxide metabolism. Inhibition of catalase by CY has been proposed as a mechanism for overcoming dormancy in...
