Evaluation of Rubus seed characteristics: seed coat morphology, anatomy, germination requirements and dormancy breaking

Creator:: Wada, Sugae
Abstract:: Rubus seed characteristics; seed coat morphology, anatomy, germination requirements and dormancy were studied in order to define protocols for breaking seed dormancy. Morphological analysis of the seed coat (testa) using scanning electron microscopy (SEM) included 56 seed accessions of 10 subgenera preserved in the collections of the US Department of...

Statistical Methods for Tissue Culture Medium Optimization and A Multiplexed Fingerprinting Set for Hazelnuts

Creator:: Akin, Melekşen
Abstract:: Hazelnut is one of the most important nuts in worldwide production and the European hazelnut (Corylus avellana L.) is the most economically important of the 11 recognized hazelnut species. Development of new cultivars is continuous, with emphasis on better nut quality, high yield and disease resistance. Hazelnuts are highly heterozygous,...

Micropropagation and regeneration of hazelnut (Corylus species)

Creator:: Yu, Xiaoling
Abstract:: A micropropagation system was developed for hazelnut cultivars and rootstocks. Culture establishment was affected by explant source, explant collecting season, and type of explant. The highest frequency of culture initiation and lowest tissue oxidation and contamination were obtained from internodes with single axillary buds from grafted greenhouse-grown plants early in...

Improving initiation and mineral nutrition for hazelnut (Corylus avellana) micropropagation

Creator:: Hand, Charles R.
Abstract:: Corylus avellana L. is a global commodity and a valuable crop for the U.S. Pacific Northwest. A tremendous amount of work has been put into the development of healthy disease free, high yielding and tasty hazelnuts for the in-shell and confectionary markets. Clonal propagation is required to provide nursery trees...

Nondestructive evaluation of in vitro-stored plants : a comparison of visual and image analysis systems

Creator:: Aynalem, Hailu M.
Abstract:: In-vitro plants in slow-growth storage must be routinely evaluated for repropagation and assessment of viability. It is often difficult to determine plant health by visual assessment due to variation in growth patterns and plant structure among genera. In order to evaluate cold-stored germplasm, laboratories need more effective approaches for viability...

Improving in vitro mineral nutrition for diverse red raspberry and Rubus germplasm

Creator:: Poothong, Sukalya
Abstract:: Red raspberry, Rubus idaeus L., is a valuable crop for the U.S. Pacific Northwest and clonal propagation is required to produce disease-free plants and for germplasm preservation. One challenge of red raspberry micropropagation is the wide variation in growth response among the cultivars. The studies described in this dissertation were...

Development, detection and elimination of Verticillium dahliae in mint shoot cultures and effects of bacterial cultures and bacterization on the growth and disease development

Creator:: Wang, Nan
Abstract:: Roots of greenhouse-grown peppermint (Mentha piperita L.) and spearmint (Mentha spicata L.) plants and in vitro-grown shoot cultures were inoculated with Verticillium dahliae conidial suspensions to study symptom development, detection, and elimination of the V. dahliae. There were significant differences in the symptom expression of control and infected shoot cultures...

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...

Detection, identification, and antibiotic treatments of bacterial contaminants from micropropagated strawberries

Creator:: Tanprasert, Piyarak
Abstract:: Bacterial contamination is one of the most important problems both in plant tissue culture research and commercial laboratories. Early detection of contaminants saves time, effort, and money. Strawberry runner explants were screened for contaminants during June to August, 1994 and 1995. Most contaminants found were bacterial rather than fungal. Bacterial...

Genetic stability of micropropagated and in vitro cold-stored strawberries

Creator:: Kumar, Mohan B.
Abstract:: Genetic stability of micropropagated and cold-stored Fragaria x anannasa cultivar 'Pocahontas' was evaluated by Random Amplified Polymorphic DNA (RAPD) assay. Plantlets grown for eight months on M & S medium with 5 μM and 15 μM N6- benzyladenine (BA) were analyzed. No evidence of mutations was seen in over 200...
