Inflorescence bulbils of tiger lily in vivo and bulbils culture in vitro

The present study includes two experiments; the physiological and the biotechnological experiments. The physiological experiment was designed to investigate the most interesting rare natural phenomenon of the development of vegetative reproductive organs (bulbils) in the inflorescence of tiger lily. In the other hand, the biotechnological experiment was carried out to evaluate the regeneration potential of bulbils...

Effects of different culture conditions (photoautotrophic, photomixotrophic) and the auxin indole-butyric acid on the in vitro acclimatization of papaya (Carica papaya L. var. Red Maradol) plants using zeolite as support

Plant regeneration of papaya via organogenesis and somatic embryogenesis has been successful; however, the biggest problem of in vitro culture of this species is the acclimatization of regenerated plants, where over 70% of the plants are lost before being planted in the field. Decreasing the relative humidity inside the culture vessel and thus increasing the ventilation, appears to have a greater effect on the...

The effects of exotic weed Flaveria bidentis with different invasion stages on soil bacterial community structures

A new exotic weed, Flaveria bidentis, is spreading in central China where it forms dense monospecific patches modifying the structure of different native ecosystems and threatening native aboveground biodiversity. However, little is known about the consequences of such an invasion for soil bacterial community, especially its effect pattern at different invasion stages. In this study, soil samples were taken in native...

Extraction and characterization of Retama monosperma fibers

The aims of this study were to determine the good conditions for fibers extraction from Retama monosperma young stems and their mechanical, physical and chemical characteristics. The fibers were extracted using a range of NaOH concentration from 1 to 16% in a period of treatment of 1 to 24 h, coupled with a physical treatment. For the evaluation of physico-mechanical characteristics, 200 samples were performed in the...
