An efficient clonal propagation procedure for six rice varieties cultivated in Argentina was developed by using shoot tip cultures, and the genetic stability of the micropropagated plants was verified by isozyme analysis. One week old seedlings obtained on MS medium were sectioned and subcultured on MS medium (0.75% agar) supplemented with different combination and concentrations of cytokinins ...

in vitro propagation of rose has played a very important role in rapid multiplication of species with desirable traits and production of healthy and disease-free plants. micropropagation using nodal segments of rosa canina under different combinations of bap, ga3 and naa on ms and vs, medium was investigated. the results showed that the highest shoot proliferation was obtained on vs medium cont...

arnebia pulchra (willd. ex roem. & schult.) edm. is an endangered, perennial member of boraginaceae family. spectrophotometric and lc-mass analysis confirmed the existence of shikalkin derivatives in its root skin and polyphenolic compounds in the inner part of its root. studies on the regeneration of a. pulchra from its callus resulted in successful callus induction in the root explants excise...

The new year is a time for goal setting, reflection, and new beginnings. Often, resolutions begin with self-improvements of the physical kind-losing weight, exercising, eating clean. These are important ideas and goals, although often difficult to sustain in part because sustaining is an implied element of each. Intentions are different than goals in the sense that an intention can be implement...

With the goal of creating faster and more efficient methods of generating unique Ac/Ds insertional mutants in a population of Fragaria vesca, various methods of seed germination, kanamycin screening, and the effects of varying nitrogen fertilization on diploid strawberry have been examined. Seed germination was improved to 42% in B5 liquid medium compared to _ on MS solid medium. Kanamycin scre...

A comparative study of in vitro seed germination of two endangered orchid species, viz. Cymbidium elegans Lindl. and Dendrobium densiflorum Lindl. ex Wall., was carried out on Murashige and Skoog’s (MS) medium, supplemented with different concentrations and combination of 6-benzylaminopurine (BAP) and á-Naphthalene acetic acid (NAA). The hormone-free MS medium and MS medium supplemented with va...

in vitro propagation of rose (rosa indica) as well as rose breeding is a valuable economic enterprise and has received highest importance globally including indian subcontinent. the development of new cultivars for commerce is faced with new challenges. in vitro micropropagation protocols of varieties of roses have been established but very few reports on the clonal propagation of local cultiva...

The study was undertaken to examine the effect of two synthetic auxins on somatic embryogenesis and plant regeneration from mature embryo explants of 16 onion cultivars. Cotyledons were removed from the embryos and remaining portions were cultured on MS medium supplemented with 1.0 mg/L 2,4-D and 5.0 mg/L picloram alone or in combination (1.0 mg/L 2,4-D + 2.5 mg/L picloram) to produce embryogen...
