Abstract:

An in vitro method for the establishment and storage of over 200 Saccharum spp. hybrid clones was developed that involved only 1 medium for shoot development and multiplication, without decontamination procedures. Apical buds from the axils of developing leaves surrounding the apical meristem were cultured on medium containing the plant growth regulators benzylamino purine and kinetin which regenerated multiple shoots. Shoots transferred to a medium containing naphthalene acetic acid and 60 g L"1 sucrose, developed roots. In vitro plants were transferred to a half strength Murashige and Skoog

Cryopreservation of gametes is a valuable tool for the fast-growing aquaculture industry in New Zealand. In the present study, research was aimed to improve the cryopreservation of Pacific oyster (Crassostrea gigas) oocytes. For this, two main approaches were used: the modification of an existing published (standard) cryopreservation protocol for oyster oocytes and the modification of the oocytes themselves prior to cryopreservation. The objectives in the chapters of this thesis were: (a) determination of the cryobiological characteristics of oyster oocytes; (b) assessment and reduction of int

Abstract:

Sweetpotato (Ipomoea batatas (L.) Lam) is an extremely diverse and important crop ranking seventh in terms of global production. It is grown throughout the world as a staple crop, and is particularly important in tropical developing countries due to its wide adaptability as well as its enormous potential for preventing malnutrition. The International Potato Center (CIP) in Lima, Peru and the USDA-ARS Plant Genetic Resources Conservation unit (PGRCU) in Griffin, Georgia are the most important sweetpotato gene banks worldwide. Roughly 7,000 and 750 accessions are present in each, respectively. B

Abstract:

This thesis provides an analysis of recent attempts to regulate the governance of genetic resources through the initiation of new global commons regimes. These attempts have arisen out of a combination of the growing recognition of genetic resources' value and global nature; a new resurgence in support for the common property paradigm; and, during a period in which the world is becoming increasingly globalised, with many governance competencies moving to the supranational level. They can be viewed as part of a broader effort to proffer the common property approach as a legitimate alternative i

Dissertation submitted in compliance with the requirements for the Master's Degree in Technology: Biotechnology, Technikon Natal, 2002.<br>Lack of suitable techniques for field collection of the germplasm of different species, and spoilage of samples in transit, hinder efforts to collect, conserve, distribute and regenerate most plant germplasm in vitro. The aims of this investigation, therefore, were to address problems encountered in collection of field germplasm from species and hybrids of Eucalyptus (TAG5, TAGI4, ZG14, GC550 and GU2IO) that are propagated vegetatively and Trichilia d

碩士<br>國立中興大學<br>園藝學系所<br>105<br>Impatiens walleriana was the important winter bedding plants in Taiwan. By observing the habitats as well as the characters of perianths and trying to pollinate, We finally picked up I. walleriana as seed parents and I. taymonii as pollen parents, expecting that the hybrides will surive and be attractive. All three native Impatiens species had the ability to set seeds in Shei-Pa national park and Mai-Feng. The seeds numbers of a capsule in Impatiens devolii was not different in two habitats. Impatiens tayemonii in Shei-Pa national park had more seeds than in Mai

Abstract:

Wild barley (Hordeum vulgare subsp. spontaneum) could be a source of useful genes for improving cultivated barley. The useful genes present in Hordeum vulgare subsp. spontaneum may be new alleles at described loci, or these may be entirely new genes in the sense that there is limited allelic variation at these loci in the cultivated germplasm pool. This research was directed at gene discovery in wild barley and involved two steps: (i) characterization of diversity using genetic markers and (ii) development and characterization of novel germplasm for gene discovery.

Abstract:

The trees belonging to the genus Podocarpus, of which only four species are native to South Africa, are renowned for their superior quality timber. Prior to 1880, Podocarpus henkelii, together with P. falcatus and P. latifolius, played a significant role in the development of the country as they were heavily utilised as timber trees for the building of dwellings, furniture and other necessary items. Due to this over-exploitation in the timber trade, all the Podocarpus species in South Africa have been afforded a ‘Protected’ status on the IUCN red data list of species that are either threatened
