Valeriana officinalis belongs to the Valerianaceae family, is a well-known herb and medicinal plant. Plant roots are commonly used as medicine by pharmaceutical industry. Observation on morpho-agronomic characteristics of valerian propagated in vitro needed determine their morphological production field. The study aimed observe derived from culture. experiment was conducted at Indonesian Spices...

Heavy metal contamination of agricultural land is partly responsible for limiting crop productivity. Cd is known as a non-essentiel HM that can be harmful to plants even at low concentrations. Brassica juncea (L.) is able to accumulate more than 400 μg.g D.W. in the shoot, a physiological trait which may be exploited for the phytoremediation of contaminated soils and waters. In our study, we ha...

New individuals in clonal populations arise through the recruitment of sexual or clonal offspring. The predominance of one type of regeneration over the other has been correlated with different selective environmental pressures. We compared the reproductive mode (sexual through seeds and vegetative through plantlets or detached cladodes) of Opuntia microdasys from three desert habitats of the C...

Embryogenesis was induced from regenerated carrot plantlets in a shorter time and at a higher frequency than that observed previously from hypocotyl explants of carrot seedlings (Masuda et al. J. Plant Physiol. 145, 531 (1995)). Serial observations of embryogenesis from single cells to globular embryos via cell clusters were possible in the conditioned medium. The ability to produce embryos see...

Growth characteristics, oxygen exchange, and carbohydrate and chlorophyll contents were determined 30 days after subculturing of single node-derived plantlets of Solanum tuberosum cv Haig cultivated in vitro. Cultivation conditions were: (a) photomixotrophy in closed vessel, (b) photomixotrophy in closed vessel on medium supplemented with silver thiosulfate, (c) photomixotrophy in aerated vesse...

Genome editing is highly useful for crop improvement. The method of expressing genome-editing enzymes using a transient expression system in Agrobacterium, called agrobacterial mutagenesis, shortcut used technology to improve elite varieties vegetatively propagated crops, including potato. However, with this method, edited individuals cannot be selected. regeneration-promoting genes can result ...

Polyploid plantlets, including triploid, tetraploid, and mixoploid, were induced from the European pear (Pyrus communis L.) cultivar ‘Fertility’ by in vitro colchicine treatment of leaf explants. The leaf explants were incubated in 0.4% (w/v) colchicine for 24, 48, or 72 h, then transferred to adventitious shoot-induction medium. Regenerated shoots were pre-selected according to their morpholog...

Background and Purpose: Black locust (Robinia pseudoacacia L.) is a valuable species native to North America and today widely planted throughout the world for biomass production. In Hungary, where Robinia has great importance in the forest management, the clones have been selected for plantations on good, medium and poor quality sites. To conserve the identity, superior clones are vegetatively ...
