RAPD analysis This study aimed to develop an efficient method for micrpropagation of true-to-type date palm plants through direct organogenesis. Nodular cultures were obtained from shoot tips on MS medium plus 2 mg/l 2ip and 1 mg/l NAA. Among combinations of 2ip and 2,4-D added to culture medium for direct shoot buds proliferation, 5 mg/l 2ip alone gave the highest organogenesis frequency. For ...

This experiment was performed to optimize the medium for tissue culture of Taraxacum kok-saghyz Rodin. Different tissue culture approaches such as shoot regeneration from seed, callus formation from leaf explants and plant regeneration from callus were investigated in this study. All the explants were cultured on MS basal medium supplemented with 20g/l sucrose, 7g/l agar and different plant gro...

A total of 231 different soil Streptomyces isolates were recovered from 16 different locations in North Jordan. They were assessed for their phytotoxic activity on seeds of cucumber (Cucumis sativus L.) and ryegrass (Lolium perenne L.) placed adjacent to a 2 cm wide Streptomyces culture strips grown at 28C degrees for 3 weeks on starch casein nitrate (SCN) agar. Phytotoxicity was ascertained on...

Salicylic acid (SA) is one of numerous phenolic compounds found in plants with numerous important physiological events. Exogenously application of Salicylic acid (SA) is useful for the growth and development of plants. This investigation aimed to study the improving effect of salicylic acid on the tissue culture of Ziziphus spina-christi. To study its improving effect were used shoot-tip explan...

In vitro techniques may provide a suitable tool for effective propagation and conservation of plant species representing various ecological niches. The elaboration of such protocols is also prerequisite for selection of heavy-metal-tolerant plant material that could be afterwards used for restoration or remediation of polluted sites. In this study, culture protocol for Gypsophila fastigiata pro...

this review article investigates a comprehensive description of the factors, methods, strategies, approaches and prerequisites influencing in vitro micropaopagation and the amount of their use across the world. the findings presented here are the results of the study of several hundred papers published all over the world. tissue culture techniques are routinely used for micropropagation. enhanc...
