In this research the effect of ethinyl estradiol on somatic embryogenesis of Medicago sativa was investigated. Seeds were grown in vitro on MS medium containing 2,4-D, Kin and NAA for callus induction. Plant regeneration media with 14 different combinations of auxin, cytokinin and ethinyl estradiol were provided. Three to four-week old celli and stem or hypocotyl segments of Medicago sativa wer...

Crataegus pontica, Cerasus microcarpa and Amigdalus orientalis are from important accompanying woody plant species in Zagros forests and their regeneration dynamic helps to improve the regeneration of tree species. This research was carried out with the aim of investigating and recognizing the regeneration establishment pattern of C. pontica, C. microcarpa and A. orientalis in three forest site...

This study was conducted to evaluate the responses of Iranian commercial genotypes of maize (hybrids and their inbred lines) to callus induction and plant regeneration, using mature embryos. Twenty five genotypes comprising of 12 inbred lines, 11 single cross hybrids, 1 double cross hybrid and 1 composite cultivar were used. Mature embryos of the genotypes were plated on MS and N6 media. Callus...

Accurate prediction of the remaining useful life (RUL) is a key function for ensuring safety and stability lithium-ion batteries. To solve capacity regeneration model adaptability under different working conditions, hybrid RUL based on complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) bi-directional gated recurrent unit (BiGRU) proposed. CEEMDAN used to divide into in...

Periwinkle (Catharanthus roseus L.) belongs to the Apocynaceae family and accumulates more than 130 terpenoid indole alkaloids (TIAs), of which two dimeric alkaloids Vinblastine and Vincristine have antineoplastic activity and are useful for treatment of various cancers. Therefore, the production of these drugs has been emphasized in plant tissue culture. In this research, 25 treatments of plan...

Gladiolus is cultivated as a high-value ornamental plant in the worldwide and it has the highest cultivation area and the highest level of underground organs imports in Iran. In this study, in order to investigate indirect regeneration of Amsterdam and Advance Red cultivars an experiment was conducted in a completely randomized design with three replications. For callogenesis, bud sprout (apica...

failure mode and effects analysis (fmea) is a method based on teamwork to identify potential failures and problems in a system, design, process and service in order to remove them. the important part of this method is determining the risk priorities of failure modes using the risk priority number (rpn). however, this traditional rpn method has several shortcomings. therefore, in this paper we p...
