Tripleurospermum insularum (Asteraceae) is a critically endangered (CR) insular endemic species in Turkey and facing high risk of extinction. Here, rapid efficient vitro propagation protocol using nodal segments obtained from seedling shoots cultured on Murashige Skoog (MS) basal medium supplemented with different plant growth regulators (PRGs) was developed to conserve T. insularum. Besides, t...

The cactus Mammillaria gracillis Pfeiff. was propagated in vitro on Murashige and Skoog (MS) medium without any growth regulators. At the bases of some plants abundant callus masses developed. Lower agar and higher MS salt concentrations stimulated callus pro­ duction. In the culture, morphologically normal and hyperhydric shoots were regenerated. The growth of crown-gall tumour was induced on ...

fars province is one of the natural habitats of pyrus species in iran. harvesting of fruits, deforestation, expansion of agriculture and overgrazing in recent years has threatened the wild pear open forests and imposed detrimental effects on their natural regeneration, therefore, investigation on propagation of wild pear species for afforestation is needed. this research was carried out to deve...

Gentiana species generally are of little importance to horticulture. This may explain that little attention has been given to virus infections in these ornamentals, so far. However, during the last couple of years the number of samples for virus diagnosis increased. The main symptoms recorded, were growth reduction, necrotic lesions and decline. The virus isolated most frequently was broad bean...

Aglaonema widuri is an evergreen and indoor ornamental plant. This study aimed to investigate the effect of some plant growth regulators on micropropagation of A. widuri. A protocol was developed for high frequency in vitro multiplication of ...

Plant phytochemicals are described as possessing considerable neuroprotective properties, due to radical scavenging capacity and acetylcholinesterase inhibitory activity, important bioactivities in neurodegeneration. Antirrhinum lopesianum is a rare endemism from the Iberian Peninsula, occurring at the northeastern border between Portugal and Spain. It is classified as Endangered, due to its hi...
