In vitro micropropagation is already a current multiplication tool for walnut self-rooted cultivars and rootstocks, but grafting still performed in the field or greenhouses, mainly using seedlings as rootstocks. The present work describes new approach to obtain clonal walnut-grafted plants, involving shoot production of ‘Paradox’ (Juglans hindsi × Juglans regia) cl. ’Vlach’, be used rootstock, ...

The effect of stationary liquid media to improve shoots elongation in date palm cv. Najda and an in vitro pre-acclimatization stage to increase the survival ercentage of plantlets in the greenhouse was investigated. Two basal liquid media were tested: full strength and half strength Murashige and Skoog medium (MS). Media were devoid of plant growth regulators (PGRs), containing 0.5 mg/L 6-benzy...

An efficient micropropagation protocol of Cyclopia genistoides (L.) Vent., an indigenous South African shrub of economic importance, was established. In vitro shoot cultures were obtained from shoot tip fragments of sterile seedlings cultured on solid Schenk and Hildebrandt (SH) medium supplemented with 9.84 microM 6-(gamma,gamma-dimethylallylamino)purine (2iP) and 1.0 microM thidiazuron (TDZ)....

ABSTRACT: Couroupita guianensis Aubl. is an Amazonian forest species with important medicinal and ornamental value. This study evaluated the effect of different culture media light spectra on in vitro germination development zygotic embryos C. guianensis. The media, MS WPM, were without addition plant growth regulators associated four LED spectra: white (CW), 70% red + 30% blue (R2B), 100% (R),...

Tissue culture techniques can be beneficial for quick clonal propagation and production of disease-free plants of purple passion fruit as one of the most important medicinal and ornamental plants. These techniques are essential tools for the production of transgenic plants and high-value phytochemicals. The present study was planned to introduce an efficient in vitro propagation for pu...

Two species of Pb-adapted shrubs, Alyssum montanum and Daphne jasminea, were evaluated in vitro for their tolerance to elevated concentrations of cadmium. Shoot cultures were treated with 0.5, 2.5, and 5.0 μM CdCl2 for 16 weeks and analyzed for their organogenic response, biomass accretion, pigment content, and macronutrient status. Cadmium accumulation and its root-to-shoot translocation were ...
