Micropropagation of Paraserianthes falcataria
… The focus of this study was to establish micropropagation techniques for Paraserianthes falcataria, in order to introduce this species as a prospective source of timber and paper of the future. Seed germination experiments were investigated for seed pre-treatments with various agents, …

Verticordia micropropagation through direct ex vitro rooting
… that these protocols would be successful in micropropagation, growth and survival of different V. grandis clones and possibly applicable to other Verticordia species. The elongation of in vitro Verticordia shoots on multiplication media was improved by reducing the concentration of BAP from …

Studies on the micropropagation of carob : Ceratonia siliqua L.
Micropropagation of carob was possible from field-grown mature trees using axillary buds as explant material. Surface sterilisation and subsequent development of the buds was difficult to achieve due to the production of phenolic exudates by the explants, which were detrimental to plant health. The …

The use of natural pressurised forced ventilation in plant micropropagation
… flower bud production,leaf and shoot growth and micropropagation have been promoted and leaf and flower bud abscission have been reduced. In cauliflower, tobacco and Annona the leaf chlorophyll contents, rates of photosynthesis and yields were improved by this forced ventilation. These beneficial …

Micropropagation of Begonia and a study of genome stability in Begonia rex
The development of procedures and media for the micropropagation of B. rex are described. Media for the production of plantlets from a number of other Begonia hybrids are also provided. Growth analysis data is given for plants produced in vivo from leaf cuttings and in vitro from mature leaf …

In vitro micropropagation, evaluation of disease resistance and hardiness of several new rose cultivars
New hardy rose cultivars, R. hybrida 'Carefree Beauty', 'Prairie Youth' and 'John Frobisher' and R. rugosa 'Henry Hudson' and 'Jens Hunk' were successfully propagated in vitro. Stem pieces containing axillary buds, leaves and roots of these cultivars were the source of explants. Shoots obtained …

Development of a Laboratory Protocol for the Micropropagation of Monterey Pines (<i>Pinus Radiata</i>), Año Nuevo Stand
… genetic clones of the resistant pines through micropropagation. These genetic clones will be used for outplanting in places outside the native stands for ornamental and plantation purposes. This project analyzes the results of ten trials with varied parameters and bases the final protocol on …

The efficient propagation method of miniature roses
… Our studies revealed the following: (1) Micropropagation is superior to conventional propagation methods for miniature rose production. (2) The budded-cutting method could potentially compete with micropropagation and single-node cuttings, especially for cultivars (e.g. 'Royal Sunblaze') …

In vitro establishment, shoot multiplication, and rooting of Pinus strobus, Pseudotsuga menziesii, and Thuja occidentalis 'Hetz Wintergreen'
Tissue culture propagation or micropropagation is an important new technology used to clone herbaceous and woody angiosperm plants. This technology would have great potential if it could be applied to mature conifers. The research objectives of this study were to improve disinfestation, axillary …

Stability of 'Thornless Evergreen' Blackberry in Vitro and Ex Vitro (Tissue Culture, Chimera, Variability, Somaclonal Variation, Rubus)
… thorny, and gametes carry the thorny gene. Via micropropagation, pure thornless plants were selected from rapidly propagated shoot tips. These pure thornless plants had shortened internodes and a characteristic "bent petiole" condition. Isolated root segments of pure thornless plants produced …

Photosynthesis and nutrition in In Vitro plants
The successful micropropagation of woody or herbaceous perennial plants is often limited by large losses which occur as plants are transferred from culture to soil. Poor photosynthetic capability may be partly responsible for losses at this stage. Results show that growth irradiance, CO 2 and …

Somatic Embryogenesis of Pathogen-Free Horseradish (Armoracia Rusticana) Plants in Vitro
… growers to restore root quality and yields. Micropropagation of PF plants through tissue culture could be used to deliver PF planting stock to growers, but it was time-consuming and has high labor costs. In addition, the growers needed millions of plants to supply their planting stock needs. …

Propagação e micropropagação de lisianthus
… of live leaves to root. The experiment used micropropagation lisianthus seedlings grown in vitro as a source of explants in factorial (4x5) represented by four culture environments (growing room, laboratory room with artificial light, laboratory room with natural light and greenhouse) and …

De novo morphogenesis on tomato thin cell layers and variation for genetic recombination among plantlets regenerated from tissue culture
… was compared among tomato plants placed into micropropagation, callus, and thin cell layer tissue culture systems. More shoots were produced on thin cell layer explants than on cotyledon calli, or micropropagated shoot tips. Genetic recombination rates and map distances were compared among …

Bud-forcing and in vitro culture for conservation of oak (Quercus L.)
… the Quercus species reached the target stage for micropropagation with all treatments, indicating that forcing bud break is a viable option for Quercus, but the rate of bud development in some species may be enhanced by BAP application. In Experiment 2, newly-flushed shoots were collected in the …
