AbstractRegeneration of Slender speedwell (Veronica filiformis) from small parts of stem without using stimulative agents was the focus of the investigation. Four different short fragments of shoot (main terminal, secondary terminal, nodal segment and internodal segment) were cultivated under greenhouse and natural conditions. All tested vegetative segments induced roots, rooted in a soil substrate and in a semi-natural lawn, survived winter, and flowered. Multiplication of clonal plants was confirmed for both the main and secondary terminal segments. These terminal segments had the best response in number of growing individuals, flowering stems, and weight of dried biomass. The manipulative experiment revealed that clonal success of speedwell is connected with possibilities to hive off of all tested above-ground segments. Establishment of plantlets from the segment in natural condition was not successful when accompanied by certain grass species.

This study reports on an improved protocol for callus induction and subsequent regeneration from nodal segment of wood apple (Aegle marmelos L.) Creamish friable competent callus was achieved from nodal segments on MS medium augmented with 4.0 mg1-1 2,4-D within two weeks of inoculation. The callus produced large number of shoots when cultured on MS medium fortified with 2.0 mgl-1 BAP+0.1 mgl-1 NAA within ten days of culture. In vitro raised shoots were rooted on half strength MS medium enriched with 1.0 mgl-1 IBA within fifteen days of culture. The rooted plantlets were successfully established with 80% survival.

We review and extend the numerous polyol-based synthesis protocols and postdeposition treatments that have been reported for silver nanowires (AgNWs). After tailoring substantial process parameters such as the process time, temperature as well as the stirring speed, the polyvinylpyrrolidone (PVP) to silver nitrate (AgNO3) ratio, and the type of PVP, a high mean aspect ratio of 800 could be achieved. Interestingly, the addition of a small portion of potassium chloride (KCl) not only leads to a reduction in diameter but also extremely enhances the nanowire dispersion and its stability. This effect is attributed to the role of KCl, which, along with PVP, acts as a cocapping agent. Furthermore, sprayed AgNW and copper nanowire (CuNW) films were tested as transparent heaters. The AgNWs could be operated at a power density of at least 0.72 W/cm2, which corresponds to a temperature of 213°C, whereas the CuNWs failed at a power density and temperature of 0.4 W/cm2 and 150°C, respectively. Interestingly, the degradation of AgNWs shows a step-wise behavior and is mainly dominated by fragmentation, while the CuNWs are gradually oxidized.

The polyamines such as putrescine, spermidine, and spermine were reported to increase green plant regeneration in rice anther culture. Low response of anther culture of rice sub-species indica may be improved with the addition of putrescine in the culture media. Four experiments were conducted to study the role of polyamines in inhibition of ethylene biosynthesis and their effects on rice anther culture development. Anthers of two subspecies of rice, indica (IR64, Krowal, Jatiluhur) and japonica (Taipei 309) were cultured onto media supplemented with putrescine (N6P) and without putrescine (N6). Young<br />panicles containing the anthers at mid-to-late nucleate microspores were cold pretreated at 5 + 2°C and incubated in the dark for 8 days before the anthers were cultured. Results<br />showed that medium without putrescine produced an earlier senescence of indica rice anther than that of japonica. The addition of 10-3 M putrescine into the culture media inhibited ethylene biosynthesis as anther senescence delayed, increased the three polyamines contents, and decreased the ACC content as well as ACC oxydase activity in anther-derived calli. In the anther and anther-derived calli of subspecies indica, the total<br />polyamines content was lower (10.14 nM g-1 anther and 8.48 nM g-1 calli) than that of subspecies japonica (12.61 nM g-1 anther and 10.16 nM g-1 calli), whereas the ethylene production was higher (32.31 nM g-1 anther and 2.48 nM g-1 calli) than the japonica (31.68 nM g-1 anther and 1.76 nM g-1 calli). This study suggests that application of 10-3 M putrescine in anther culture of rice subspecies indica improves androgenesis by inhibiting<br />early senescence of cultured anthers and enhancing embryo or callus formation from microspores.
