The aim of these experiments was to apply magnesium (50 and 100 mg Mg kg soil) to neutralise the potentially negative effects of soil contamination by cadmium (10, 20, 30 and 40 mg Cd kg soil) on the number of some groups of microorganisms. Another objective was to determine the relationship between the number of these microorganisms relative to yield of yellow lupine and some physicochemical p...

Atriplex taltalensis is an endangered shrub endemic to northern Chile. Sparse populations of this species can be found in areas with extreme edaphoclimatic conditions the Atacama desert, and its seeds have a poor germination rate. Consequently, mass-cultivating it challenging. In study, vegetative propagation mechanisms A. were evaluated using vitro culture aid their conservation. shoot explant...

The resurrection plant Selaginella pulvinata (Hook. & Grev.) Maxim is used as an ornamental and medicinal plant. It also a good candidate for exploring the desiccation tolerance of plants. However, there not efficient propagation method S. . In present study, we evaluated establishment in vitro using frond tips explants. original shoot induction, adventitious proliferation plantlet growth m...

Objective: Here, we established the protocol for plant regeneration of Psoralea corylifolia via In-vitro micro propagation. Methods: The Apical meristems was used as the explants cultured on Murashige and Skoog (1962) medium (MS) supplemented different concentrations and combinations of plant growth regulators, 6-Benzylaminopurine (BAP), Kinetin (Kn), 1-Naphthaleneacetic acid (NAA) and B5 vitam...

Aboveground organs of plants are ultimately derived/generated from the shoot apical meristem (SAM), which is a proliferative tissue located at the apex of the stem. The SAM contains a population of stem cells that provide new cells for organ/tissue formation. The SAM is composed of distinct cell layers and zones with different properties. Primordia of lateral organs develop at the periphery of ...

A complete protocol is presented for in vitro regeneration of pomegranate (Punica granatum L.), a tropical fruit tree, using cotyledonary nodes derived from axenic seedlings. Shoot development was induced from cotyledonary nodes on Murashige and Skoog (1962) (MS) medium supplemented with 2.3±23.0 mM benzyladenine (BA) or kinetin (Kn). Both type and concentration of cytokinin signi®cantly in ̄uen...

The effects of major mineral salts, L-glutamine, myo-inositol and carbon source on shoot bud proliferation of date palm (Phoenix dactylifera L.) cv. Mejhoul were evaluated. Different concentrations of ammonium nitrate (NH4NO3; 550, 825 or 1650 mg/L), potassium nitrate (KNO3; 633.3, 950 or 1900 mg/L), calcium chloride dehydrate (CaCl2·2H2O; 147, 220 or 440 mg/L), potassium dihydrogen phosphate (...
