Suboptimal nitrogen (N) availability is a primary constraint for crop production in developing countries, while in developed countries, intensive N fertilization is a primary economic, energy, and environmental cost for crop production. We tested the hypothesis that under low-N conditions, maize (Zea mays) lines with few but long (FL) lateral roots would have greater axial root elongation, deep...

Abstract Corydalis saxicola Bunting, a medicinal herb known for alkaloids, grows mainly in Guizhou province and northwest Guangxi of China. In this study, the first time plant, an efficient adventitious shoot proliferation regeneration system via organogenesis from leaf petiole explants was established. Cytokinins, including 6-benzyladenine (BA) thidiazuron (TDZ), induced callus then organogene...

a methodology to regenerate whole plants of fig tree (ficus carica cv. jaami-e-kan) from apical meristem of greenhouse plantlets was developed. two meristematic explants size (0.2-0.4 and 0.5-0.7 mm), two kinds of culture media and three concentrations of 6-benzyladenine (0.5, 1 and 1.5 mgrl-1) were tested as a completely randomize design (crd) with a simple factorial arrangement for establishm...

In this study, several methods have been used to facilitate shoot formation from nodal explants of local almond ecotypes known as “Beldi” grown in Eastern Morocco. Nodal segments divers old genotypes were cultured on various concentrations auxin (indole-3-butyric acid (IBA)) and cytokinins (6-benzyl-aminopurine (BAP), thidiazuron (TDZ), kinetin (KIN)) added two different media (Murashige Skoog ...

A complete micropropagation protocol was developed for Pistacia vera cv. Ghazvini, an important rootstock in Pistachio orchards in Iran. In present study, the efficiency of a new medium called GNH (Garoosi, Nezami and Haddad) was investigated against some standard media. Different vitamins, calcium (Ca) sources and plant growth regulators (PGRs) were tested on in vitro shoot multiplication and ...

In vitro propagation method was developed for obtaining large number of plantlets of Valeriana wallichii DC. (Valerianaceae), an indigenous high value medicinal and aromatic plant species of Indian Himalayan region, using nodes of in vitro grown seedlings. High frequency shoot proliferation was induced in explants cultured on Murashige and Skoog (MS) medium supplemented with different concentra...

The genus Berberis vulgaris ( L.) is currently found in tropical, subtropical, temperate, and cold climate zones. There little doubt that Southeast Asia where the majority of vulgaris' interspecies biodiversity found. Additionally, species are widely distributed, mostly hilly areas, and, terms moisture requirements, they mesophytic xeromesophytic plants. In this article, experiments on in-vitro...

The current study envisages producing Cordyline plants on a large scale employing costeffective In vitro protocols. The effect of various concentrations and types of plant growth regulators were observed to optimize the efficient media for propagation. Axillary buds excised from the greenhouse grown mother plants of Cordyline terminalis were cultured on MS medium supplemented with BAP (1.0-2.0 ...

Rosmarinus officinalis L. belongs to the Lamiaceae family and is cultivated worldwide due its diverse uses as an ornamental evergreen shrub in gardening, well a food seasoning natural medicine. The present research was conducted study morphological traits of seven wild-grown rosemary populations Greece, propagation two selected with most desirable characteristics, by use shoot cuttings vitro cu...

Orchids have a long period of production and need to be under the right conditions. Therefore, in vitro propagation is an alternative reduce time. This study aimed determine optimal conditions two species orchids, Cattleya maxima Lindl. Phalaenopsis amabilis (L.) Blume. For this goal, experiments were carried out: multiplication rooting, for both species. In experiment, treatments differentiate...
