This article used thiosemicarbazide and para-pyridinecarboxylic acid to carry out reaction and synthesized 5-(4-pyridyl)-2-amino-1,3,4-thiadiazole, and then reacted with benzoyl isocyanate to synthesize a new type of urea biological active meterial. The structure of the target compound was confirmed by IR, 1H NMR and elemental analysis. The preliminarily biological activity tests show that the target compound has an activity as plant growth regulator, it’s activity as auxin is 19.3% and it’s activity as cytokinin is 27.4%.

The effects of three paclobutrazol (PBZ) application methods on ornamental characteristics of two pepper cultivars (‘Biquinho Vermelha’ and ‘Bode Amarela’) were evaluated. Plant growth regulator at 10 μM PBZ was added at transplanting by drenching 250 mL PBZ solution on the pot substrate, foliar spray of 10 mL PBZ solution or by submerging seedlings root + substrate for 10 seconds in the PBZ solution. Control plants were treated with tap water applied directly on the substrate. Plant height, canopy compactness, fruits and leaves number, and leaf chlorophyll content were evaluated when 50% of the plants had approximately 30% of mature fruits (commercial maturity). PBZ applied by drenching influenced positively the ornamental characteristics of ‘Bode Amarela’. Otherwise, the best PBZ application method for ‘Biquinho Vermelha’ was not established. The results suggest that search for suitable PBZ application method that no affects the pepper ornamental characteristics must be done specifically for each pepper cultivar.

One of the problems associated with preplant bulb dips into plant growth regulator (PGR) solutions is the lack of knowledge of solution efficacy as an increasing number of bulbs are treated. We evaluated the effectiveness (“longevity”) of paclobutrazol (Bonzi) and uniconazole (Sumagic) solutions repeatedly used to dip hybrid lily (Lilium sp.) bulbs. Experiments were conducted over a 2-year period, using sequential 1-minute dips into paclobutrazol (100 or 200 mg·L–1) or uniconazole (2.5 mg·L–1). No difference in plant height occurred as the number of bulbs dipped into PGR solutions increased to at least 55 bulbs per liter. This was true whether bulbs were washed (with tap water to remove soil particles attached to the bulbs) or unwashed prior to the PGR dip. These findings have an important impact on cost effectiveness of bulb dips, as the more times the solution can be used, the lower the cost. Washed bulbs were taller than unwashed bulbs due to lower PGR liquid uptake in washed bulbs (about 1 mL less per bulb) compared to the unwashed bulbs. These results indicate that the hydration condition of bulbs prior to dipping can affect the amount of PGR liquid uptake and therefore final plant height.

Seed Mediated

Silver nanoplates (SNPs) having different size were synthesized by a seed-mediated method. The seeds -silver nanoparticles with 4 – 6 nm diameters were synthesized first by reducing silver nitrate with sodium borohydride in the present of Trisodium Citrate and Hydrogen peroxide. Then these seeds were developed by continue reducing Ag\(^+\) ions with various amount of L-Ascorbic acid to form SNPs. Our analysis showed that the concentratrion of L-Ascorbic acid, a secondary reducing agent, played an important role to form SNPs. In addition, the size and in-plane dipole plasmon resonance wavelenght of silver nanoplates were increased when the concentration of added silver nitrate increased. The characterization of SNPs were studied by UV-Vis, FE-SEM, EDS and TEM methods.
