“…The effective size of the variance Ne is important to be able to determine the minimum number of seed donor trees in the collection process. Thus, the results show the importance of estimating the size of the samples designated for use in breeding programs, genetic conservation, seed collection, and addressing environmental recovery, as well as for the monitoring of genetic diversity in manipulated populations [24,42,44].…”

“…These microsatellite loci were amplified by polymerase chain reaction (PCR) using a Veriti thermal cycler (Applied Biosystems, Foster City, CA, USA) with a total volume of 10 µL per reaction (containing 10 ng of genomic DNA, 1× buffer, 210 µM of each dNTP, 1.5 mM MgCl 2 , 0.16 µM forward primer and M13 (FAM or NED) broth [23], 0.32 µM reverse primer, 1.05 U Taq DNA polymerase (Invitrogen, Carlsbad, CA, USA), and 3.49 µL ultrapure water. These PCR amplifications consisted of two steps, of which the first was primer-specific and the second M13 binding [24]. The amplification products were checked by electrophoresis on 1.5% agarose gels stained with GelRed (Biotium, Fremont, CA, USA) in 1× TBE buffer (pH 8.0).…”

The Amazonian native tree species Parkia multijuga has potential silvicultural characteristics that can be utilized to productive plantations. Understanding its mating system is necessary to delineate the methods for the breeding of the species, the collection of seeds for conservation, and the use of seedlings for production plantations. The aim of this study is to evaluate the mating system and population genetic diversity of P. multijuga, using molecular markers. The DNA of 221 plants was extracted and genotyped with nine microsatellite loci using capillary electrophoresis in an automated DNA sequencer. The estimates for single and multilocus crossing rates were 0.998 and 1.0, respectively. The paternity correlation was low (r^p(m) = 0.307). The fixation index (f) showed values below zero, indicating an excess of heterozygotes. The cluster number K = 2 shows a better grouping among families for genetic structure. P. multijuga families consist mainly of half-sibs, and the reproductive strategy of the species is allogamy.

“…Swietenia macropnylla King (SMK) belongs to the family Meliaceae, which is commonly known as mahogany. It is native to the tropical regions of America, spreading from Materials 2023, 16, 6558 2 of 11 southern Mexico to the North of Brazil [11]. In Taiwan, SMK has been extensively planted in the plain area to exploit it as available wood material for making furniture and other advanced wood products.…”

In this work, the Honduras Mahogany (Swietenia macropnylla King, SMK) seed husk was used as a novel biomass resource for producing activated carbon by physical activation. The texture characteristics and chemical characterization of resulting products were investigated in correlation with the process parameters. Based on the thermochemical properties of the SMK biomass, the process conditions were set to a rate of about 10 °C/min under nitrogen (N2) flow of 500 cm3/min heated to 500 °C, then switched to carbon dioxide (CO2) flow of 100 cm3/min in the specified activation conditions (i.e., temperature of 700–850 °C for holding times of 0–60 min). Our findings showed that the texture characteristics (i.e., surface area and pore volume) increased with an activation temperature increase from 700 to 800 °C for a holding time of 30 min but gradually decreased as the temperature increased thereafter. Similarly, the texture characteristics also indicated an increasing trend with the residence time extending from 0 min to 30 min but slightly decreased as the time was extended to 60 min. Therefore, the optimal activation conditions for producing SMK-based activated carbon should be set at 800 °C for a holding time of 30 min to obtain the maximal texture characteristics (i.e., BET surface area of 966 m2/g and total pore volume of 0.43 cm3/g). On the other hand, the chemical characteristics were analyzed by energy dispersive X-ray spectroscopy (EDS) and Fourier Transform infrared spectroscopy (FTIR), showing oxygen complexes contained on the hydrophilic surface of the resulting activated carbon.
