A substantial number of micropropagated plants do not survive transfer from in vitro conditions to greenhouse or field environment. The greenhouse and field have substantially lower relative humidity, higher light level and septic environment that are stressful to micropropagated plants compared to in vitro conditions. The benefit of any micropropagation system can, however, only be fully reali...

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 ...

The establishment of new in vitro cultures is often a difficult task due to low growth of initial explants. The explant has to adapt to the new nutritional and environmental conditions, in addition to the surface-disinfection process. Since the explant origin plays an important role, in this work, the effect of the origin of the explants (micropropagated or conventionally propagated plants) in ...

Differences in rooting ability of birch (Betula pubescens J.F. Ehrh.) cuttings were observed as a result of differences in genotype and physiology of the stock plants. The uniformity in response among cuttings from micropropagated plants compared with cuttings from seed plants confirmed the advantage of using micropropagated plants to study environmental effects. Shoot morphology of the seed st...

Molecular markers are efficient for assessing the genetic fidelity of various species of plants after in vitro culture. In this study, we evaluated the genetic fidelity and variability of micropropagated cassava plants (Manihot esculenta Crantz) using inter-simple sequence repeat markers. Twenty-two cassava accessions from the Embrapa Cassava & Fruits Germplasm Bank were used. For each accessio...

Antibacterial properties of plasma activated water (PAW) were investigated in two plant pathosystems: Xanthomonas vesicatoria (Xv) infected tomato plants and ‘Candidatus Phytoplasma asteris’ infected periwinkle micropropagated shoots. Bacterial leaf spot severity caused by Xv was reduced and a reduced symptomatology and lack of bacterial colony formation in PAW treated periwinkle micropropagate...

Cecropia glaziovi Sneth. (syn. C. glaziovii, C. glazioui) (Cecropiaceae) is a South American medicinal plant whose antihypertensive activity is attributed to its flavonoid and proanthocyanidin contents. The seasonal and intraspecific variations of these two classes of compounds in C. glaziovi leaves were assayed by spectrophotometry in samples of young and mature leaves collected from native, c...

Inter-simple sequence repeat (ISSR) markers were used to evaluate the genetic stability of the micropropagated plants of Cannabis sativa over 30 passages in culture and hardening in soil for 8 months. A total of 15 ISSR primers resulted in 115 distinct and reproducible bands. All the ISSR profiles from micropropagated plants were monomorphic and comparable to mother plants, confirming the genet...

Maguey, Agave salmiana, is an important plant for the "pulque" beverage and functional food industries; however, it has several constraints for elite and homogeneous plant production. In this study, a micropropagation process was established to generate in vitro plants. The effect of the method on metabolite content and antioxidant (AOX) activity in regenerated plants was evaluated. Young germi...

plant tissue culture refers to growing and multiplication of cells, tissues and organs of plants on defined solid or liquid media under aseptic and controlled environment. micropropagation allows rapid production of high quality, disease-free and uniform planting material. the micropropagation of high quality planting materials of ornamentals, and forest and fruit trees has created new opportun...
